00:00:00.000 --> 00:00:23.240
I got this oh so glorious power supply from Freedgeek, which has most of what I need.

00:00:23.240 --> 00:00:26.760
So I don't need pretty much any of these cables.

00:00:26.760 --> 00:00:34.040
The only all I actually need is two 8 pin CPU power connectors, because I'm taking each

00:00:34.040 --> 00:00:37.040
one and going to each individual board.

00:00:37.040 --> 00:00:49.600
However, this one only has one, though I went and also grabbed a whole bunch of cable mod

00:00:49.600 --> 00:00:55.240
cables. So I grabbed a whole bunch of cable mod cables that someone was going to toss.

00:00:55.240 --> 00:01:05.240
So I have another CPU power connector here. So I'm going to deep in these, well either deep in it or just cut it and then splice

00:01:05.240 --> 00:01:12.600
it in. But I'll pull a whole bunch of 12 volt and ground lines, both from Molex and probably

00:01:12.600 --> 00:01:18.880
from this PCI-E connector, and just splice it all into this connector here.

00:01:18.880 --> 00:01:22.600
There's a very good chance that I might just be able to deep in all of this, though I don't

00:01:22.600 --> 00:01:25.600
have the tool on me.

00:01:25.600 --> 00:01:29.000
So I'll probably just end up snipping a whole bunch of stuff and heat shrinking down anything

00:01:29.000 --> 00:01:35.920
I don't need. So off to that, and also I'll be actually not these ones.

00:01:35.920 --> 00:01:44.080
So I have these six, six pin Molex connectors, which aren't actually what I'm going to be

00:01:44.080 --> 00:01:47.560
using. Although they probably were fine.

00:01:47.560 --> 00:02:09.960
My nice bunch of goodies. What I'm actually going to be using, if I can find them, ha, it's this.

00:02:09.960 --> 00:02:14.400
So this is actually a 10 pin Molex connector.

00:02:14.400 --> 00:02:21.400
But I'm just going to cut off two of the pins and just use that instead, assuming the polarity

00:02:21.400 --> 00:02:29.680
is correct, which I actually need to double check still, but I can do that right now.

00:02:29.680 --> 00:02:35.280
So I have my nice four pin CPU power connector and it's going to plug in, it's not going

00:02:35.280 --> 00:02:44.920
to be, it's not going to interface nicely with this. Actually labeled board, I have VCC on the bottom and then ground on the top, which if

00:02:44.920 --> 00:02:54.160
I look at the connector, I have exactly the opposite of that.

00:02:54.160 --> 00:02:58.160
Well, that sucks.

00:02:58.160 --> 00:03:03.440
Can I put it in backwards?

00:03:03.440 --> 00:03:07.360
No, I can't because Molex is keyed like that. Okay.

00:03:07.360 --> 00:03:14.360
Well, that complicates things a little bit.

00:03:14.360 --> 00:03:34.680
Okay, so that either means I deep in all of this, or I just force it in upside down,

00:03:34.680 --> 00:03:38.840
which is actually an option.

00:03:38.840 --> 00:03:59.920
I think I may end up just deep pinning all of them, yeah, because I just straight up

00:03:59.920 --> 00:04:06.920
got that backwards.

00:04:06.920 --> 00:04:14.200
Oh, shite, pardon my French.

00:04:14.200 --> 00:04:22.880
I know I got it wrong because PCIe has ground on the top and VCC on the bottom, which lines

00:04:22.880 --> 00:04:28.640
up with how I pinned it out, where CPU power is inverted.

00:04:28.640 --> 00:04:37.280
So that's where that issue came from, okay.

00:04:37.280 --> 00:04:41.840
I mean, I could get away with just using this and using the PCIe connector, but with this

00:04:41.840 --> 00:04:48.080
power supply, I'd still need to swap out one of the other cables.

00:04:48.080 --> 00:04:55.840
That will connect into a problem, but I still need power for both boards.

00:04:55.840 --> 00:05:04.360
And realistically, this one, which is the middle chunk capacitor, is going to be a high

00:05:04.360 --> 00:05:11.960
power board than this small one. I mean, just look at the size of the components, like I'm going to need to actively heat sink

00:05:11.960 --> 00:05:19.400
all of these. I'm also going to have to actively heat sink these so they don't go boom too.

00:05:19.400 --> 00:05:23.760
Ask me how I know.

00:05:23.760 --> 00:05:38.600
Okay, I'm going to actually go grab the deep pinning tool and see what I can make happen

00:05:38.600 --> 00:05:48.880
with the connections I have currently, and I'll grab some of the Molex tools as well.

00:05:48.880 --> 00:05:59.120
All right, so I went and grabbed all the tools I need in theory, couldn't find the deep pinning

00:05:59.120 --> 00:06:06.960
tool for Molex, but grabbed some nice crimps and a crimper, and then promptly realized the

00:06:06.960 --> 00:06:15.040
fact that I have two PCIe cables, and they are conveniently oriented the correct way

00:06:15.040 --> 00:06:27.400
to power each board. I'm pretty sure, not 100% sure, but pretty sure, each individual PCIe cable with only

00:06:27.400 --> 00:06:35.560
six conductors going should provide enough power for what I need, obviously to be confirmed.

00:06:35.560 --> 00:06:40.280
And if that is the case, these extra cables are just going to be chilling.

00:06:40.280 --> 00:06:45.960
And regardless, I'm probably going to trim off all of my, all of the unused cables and

00:06:45.960 --> 00:06:53.080
take the sense pin on the power supply and hook it up to an external switch on the outside

00:06:53.080 --> 00:07:00.400
of the case. So I can turn this thing on and off, so I can turn the control side on and off independently

00:07:00.400 --> 00:07:06.920
from the power side, because that just seems like a very good idea given the scope of what

00:07:06.920 --> 00:07:10.680
this project is very quickly becoming.

00:07:10.680 --> 00:07:17.360
But in the interim, I'm going to get this power supply and crap out of the way, and

00:07:17.360 --> 00:07:29.240
get some soldering going for these PCIe connectors, so I'm going to solder each one of these,

00:07:29.240 --> 00:07:34.040
one of these into each one of the boards, and then I can have some power, I may end

00:07:34.080 --> 00:07:37.760
up having to snip off these connectors here. TBD.

00:07:37.760 --> 00:07:42.440
But we shall see.

00:07:42.440 --> 00:07:45.440
We shall see.

00:07:45.440 --> 00:07:54.440
Fun times with me and doing the jank.

00:07:54.440 --> 00:08:05.520
Yeah, thanks for, thanks for watching if you're so inclined, and if this actually makes the

00:08:05.520 --> 00:08:11.880
final cut. I should honestly be a little bit surprised, but you never know.

00:08:11.880 --> 00:08:22.880
Let's do this chunky bit first.

00:08:22.880 --> 00:08:40.640
Okay, so I want to be taking this and go like, oh great, the pins don't line up.

00:08:40.640 --> 00:08:45.720
My favorite, the pins don't line up, and the whole size is incorrect.

00:08:45.720 --> 00:08:52.840
Man, I'm just having bad times with this recently.

00:08:52.840 --> 00:09:10.440
Even though this is supposed to be a standard pitch, okay, well, if in doubt, jank city,

00:09:10.440 --> 00:09:21.440
yo. Yeah, that's not going to fly, is it?

00:09:21.440 --> 00:09:30.440
Okay, well, that's an interesting complication that I wasn't anticipating.

00:09:30.440 --> 00:09:47.440
So, in terms of things I can do immediately regardless is desolder these connections.

00:09:47.440 --> 00:10:08.240
Okay, that's having it.

00:10:08.240 --> 00:10:15.240
Come on, you can do it, Haco.

00:10:15.240 --> 00:10:25.240
Maybe you can't.

00:10:25.240 --> 00:10:43.040
All right, time to bust out the alternative soldering iron.

00:10:43.040 --> 00:10:52.080
This is a nice little TS100 that I acquired not too long ago, and just generally speaking

00:10:52.080 --> 00:11:03.040
I've been very happy with it, although I don't quite see the chisel tip I was hoping to use.

00:11:03.040 --> 00:11:10.040
Oh, that one.

00:11:10.040 --> 00:11:33.040
Okay, so the full-on backup plan here, if all else really fails epically, is to just

00:11:33.040 --> 00:11:40.240
snip the conductors and direct solder them, though obviously I would really rather not

00:11:40.240 --> 00:11:44.040
do that. Okay, well, actually, I guess that's not that obvious.

00:11:44.040 --> 00:12:09.040
I would really rather not direct solder my conductors off of a power supply just in general.

00:12:09.040 --> 00:12:25.040
Okay.

00:12:25.040 --> 00:12:49.040
Okay.

00:12:49.040 --> 00:13:04.040
Aha, there we go.

00:13:04.040 --> 00:13:14.040
Okay. Sorry, brief little detour, as I probably think that a cable is a different cable.

00:13:14.040 --> 00:13:39.040
Okay, let's just make this bad boy.

00:13:39.040 --> 00:13:58.040
Okay, so let's get this going.

00:13:58.040 --> 00:14:01.040
Coming. There we go.

00:14:02.040 --> 00:14:19.040
Okay, so let's take this one out first.

00:14:19.040 --> 00:14:27.040
So one of the downsides of this particular setup is I did not get a lot of thermal relief

00:14:27.040 --> 00:14:42.040
between these pins or these holes and the ground planes, which means if it's on this

00:14:42.040 --> 00:14:47.040
one, which means that they're not the same.

00:14:47.040 --> 00:14:52.040
The whole sizes are different between this board and this board, even though they're supposed

00:14:52.040 --> 00:15:01.040
to be the same. So I have the gloriously fun time of figuring out what the heck I'm going to do about that

00:15:01.040 --> 00:15:07.040
in the interim. I'm going to solder this one up because for the time being, this is the one of interest

00:15:07.040 --> 00:15:15.040
because I don't have the rest of the circuitry built to do the other one, yet this I'm actually

00:15:15.040 --> 00:15:23.040
going to do some fan because this is going to be a non-trivial amount of solder, not a

00:15:23.040 --> 00:15:27.040
small amount of soldering. Sorry for the audio.

00:15:27.040 --> 00:15:34.040
Speaking of those non-thermal relief ground planes, that's what I'm struggling with right

00:15:34.040 --> 00:15:39.040
now. So if I can get away with it, I'm actually going to flip this over and solder the other

00:15:39.040 --> 00:15:44.040
side too just to make sure it's a good connection because, yeah.

00:15:44.040 --> 00:15:47.040
Okay, now comes some fun stuff.

00:15:47.040 --> 00:15:54.040
So I get to do the ground sides. So I'm going to do a bad thing and just prank my soldering iron to make this easier.

00:15:54.040 --> 00:15:58.040
This thing can get hot. All right, one, one, three.

00:15:58.040 --> 00:16:04.040
Swits. So I'm actually going to flip this over and go from the bottom again at this higher time.

00:16:04.040 --> 00:16:08.040
Yeah, that looks a lot better. Okay, now I get to think about what the heck I'm going to do with this one.

00:16:08.040 --> 00:16:13.040
I guess I also get to try to find the other connector that I inevitably put somewhere

00:16:13.040 --> 00:16:17.040
done. There, okay. All right, back at it with bad ideas.

00:16:17.040 --> 00:16:26.040
So I have decided I'm going to take a stab at, oh, I have decided that I'm going to try

00:16:26.040 --> 00:16:30.040
to just thotter just the tips.

00:16:30.040 --> 00:16:38.040
Don't do this, ever. This is a terrible idea in every single way and is almost certainly not going to work

00:16:38.040 --> 00:16:45.040
properly. Yeah, I would not recommend this in any way, shape, or form.

00:16:45.040 --> 00:16:49.040
This is a terrible idea. Don't do this.

00:16:49.040 --> 00:16:52.040
But that's why I'm doing it.

00:16:52.040 --> 00:16:55.040
So you know why not to.

00:16:55.040 --> 00:17:01.040
Okay, so let's start with this one because this one is going to be the biggest pain in

00:17:01.040 --> 00:17:08.040
the world. Sorry, audio. This is going to be a time lapse most likely anyway.

00:17:08.040 --> 00:17:14.040
Yeah, this has got comfortably in the do not do this file.

00:17:14.040 --> 00:17:17.040
This is just dumb.

00:17:17.040 --> 00:17:26.040
Okay, well, oh yeah, also crank the temp if you're going to try this because you're just

00:17:26.040 --> 00:17:30.040
don't just just don't do this.

00:17:30.040 --> 00:17:33.040
Okay, it's working.

00:17:33.040 --> 00:17:38.040
Okay, no, I'm not getting decent. I am getting joints.

00:17:38.040 --> 00:17:43.040
These are not even close to what I would call decent joints.

00:17:43.040 --> 00:17:49.040
Not even a little bit, but it is technically working.

00:17:49.040 --> 00:17:58.040
Okay, well, I'm honestly kind of baffled at the moment because that shouldn't have worked.

00:17:58.040 --> 00:18:01.040
Wow. It worked. Holy moly.

00:18:01.040 --> 00:18:07.040
Okay, cool. That was a mind-bogglingly bad idea that somehow worked.

00:18:07.040 --> 00:18:12.040
Okay, to give you a little bit more of a close-up on what I was actually doing here.

00:18:12.040 --> 00:18:16.040
So I had, okay, I can probably show you one of this on this one here.

00:18:16.040 --> 00:18:24.040
So literally what I was doing was just taking the tips, just the tips and then having a solder

00:18:24.040 --> 00:18:34.040
fillet essentially around the entire tip, joining just this little tiny tippy piece around.

00:18:34.040 --> 00:18:42.040
And it actually fricking worked somehow and it's actually like vaguely stable.

00:18:42.040 --> 00:18:47.040
I would not trust this for a whole bunch of plugs and unplugged, but for what I'm doing,

00:18:47.040 --> 00:18:51.040
good enough.

00:18:51.040 --> 00:18:58.040
So now, honestly, legitimately baffled by that one.

00:18:58.040 --> 00:19:01.040
Okay.

00:19:01.040 --> 00:19:06.040
So, now what?

00:19:06.040 --> 00:19:16.040
Okay, I'm going to do some blast for me.

00:19:16.040 --> 00:19:18.040
Where are my sneakers?

00:19:19.040 --> 00:19:28.040
This is another one of those, don't do this. This power supply was destined for the Carpegio.

00:19:28.040 --> 00:19:31.040
Although of course, your power supplies are great.

00:19:31.040 --> 00:19:37.040
It's seen better days. I'm actually probably going to clean this up and give it a nice little blast of air.

00:19:37.040 --> 00:19:43.040
But yeah, this is not going to be used to power a computer ever again.

00:19:43.040 --> 00:19:51.040
So what I'm doing is I'm just going to snip these two conductors here.

00:19:51.040 --> 00:19:56.040
So this green one is what actually tells the power supply that it's connected to a motherboard

00:19:56.040 --> 00:20:01.040
if it's pulled to ground. So I'm pulling that off and then I'm pulling the ground off.

00:20:01.040 --> 00:20:05.040
And for right now, don't do this.

00:20:05.040 --> 00:20:13.040
I'm just going to solder them together. Eventually, I will pull both of these out to a switch.

00:20:13.040 --> 00:20:18.040
And this will supply me all of my power for...

00:20:18.040 --> 00:20:23.040
Come on, there we go. Actually, I guess I can just twist these together.

00:20:23.040 --> 00:20:27.040
Okay, easy there.

00:20:27.040 --> 00:20:32.040
Okay, so what I'm going to do here is just snip the back side.

00:20:32.040 --> 00:20:37.040
Because the amount of solder that's on this side is substantially less than on the other side,

00:20:37.040 --> 00:20:41.040
which means it'll be a lot easier to pull the conductors out through that side

00:20:41.040 --> 00:20:48.040
rather than trying to pull this gigantic blob of solder through the board this way.

00:20:48.040 --> 00:20:53.040
So hopefully that should make my life quite a bit easier.

00:20:53.040 --> 00:20:58.040
Hopefully. We'll see if that actually pans out.

00:20:58.040 --> 00:21:04.040
And then just last words. I hope not, but, you know,

00:21:04.040 --> 00:21:11.040
so with anything in this company,

00:21:11.040 --> 00:21:15.040
you say something and then you immediately eat your words.

00:21:15.040 --> 00:21:18.040
Okay, got some of it. Hey, there we go.

00:21:18.040 --> 00:21:22.040
So that wasn't pretty, but if it works, it works, yo.

00:21:22.040 --> 00:21:26.040
If it works, it works. Okay, next one.

00:21:26.040 --> 00:21:30.040
This one will hopefully be worse. It should be better actually.

00:21:30.040 --> 00:21:39.040
The 5V plane, or sorry, the VCC plane on this board is not quite as numerous as the ground planes.

00:21:39.040 --> 00:21:46.040
If I recall correctly, I have two completely independent ground planes on this thing.

00:21:46.040 --> 00:21:53.040
And these ground pins might actually be connected to other things as well.

00:21:53.040 --> 00:22:00.040
Actually, this bottom plane is a 5V plane.

00:22:00.040 --> 00:22:03.040
Where is it ground?

00:22:03.040 --> 00:22:10.040
No, I think it's, I think it's 15V, sorry, 12V, whatever VCC is.

00:22:10.040 --> 00:22:13.040
How the brain?

00:22:13.040 --> 00:22:18.040
Brain and not a having it today.

00:22:18.040 --> 00:22:22.040
Okay, so this is some good work.

00:22:22.040 --> 00:22:25.040
It's generally speaking pretty good.

00:22:25.040 --> 00:22:30.040
Obviously for stuff like that, that's not going to do it, but that's fine.

00:22:30.040 --> 00:22:33.040
I don't expect it to.

00:22:33.040 --> 00:22:43.040
Okay, so actually I'm going to quickly desolder this inductor as well.

00:22:53.040 --> 00:22:55.040
Come on.

00:22:58.040 --> 00:23:00.040
Okay.

00:23:07.040 --> 00:23:14.040
Come on. I actually have to make a couple of modifications to this particular board as well.

00:23:14.040 --> 00:23:22.040
So I went through a whole bunch of troubleshooting after I blew up two of these gate drivers,

00:23:22.040 --> 00:23:28.040
and spent a whole bunch of time doing simulations in LT-SPICE,

00:23:28.040 --> 00:23:32.040
which is essentially a circuit simulation software.

00:23:32.040 --> 00:23:40.040
So what I wasn't sure about was if I was like overcurrenting these chips or something like that,

00:23:40.040 --> 00:23:47.040
I'm pretty sure what was actually happening was they were just melting themselves to death.

00:23:47.040 --> 00:23:50.040
Originally I had a 2.2 microfarad capacitor here,

00:23:50.040 --> 00:23:53.040
and my assumption was that that was what was causing me the problem,

00:23:53.040 --> 00:24:03.040
and its capacity was just too big. Turns out what's most likely happened was actually my inductance was too small for the rest of my circuit,

00:24:03.040 --> 00:24:06.040
and my current was just spiking way too hard.

00:24:06.040 --> 00:24:11.040
So from the most recent iteration of my simulations,

00:24:11.040 --> 00:24:16.040
I'm actually going to pull this wire out, put the 2.2 microfarad cap back in,

00:24:16.040 --> 00:24:26.040
and then I just wound this toroid a few more times to get it up to 27 microhenrys up from like the 10,

00:24:26.040 --> 00:24:35.040
or something like that that was the first time, and I'm hoping that that should allow me to drive this second side properly.

00:24:35.040 --> 00:24:40.040
And once I actively cool these two chips,

00:24:40.040 --> 00:24:46.040
hopefully they won't find themselves in a fiery grave,

00:24:46.040 --> 00:24:50.040
but that's optimistic,

00:24:50.040 --> 00:24:56.040
because they are very small chips for the amount of power going through them,

00:24:56.040 --> 00:25:00.040
and I'm pretty sure if I had been thinking this through properly,

00:25:00.040 --> 00:25:03.040
I would have sourced the higher power versions,

00:25:03.040 --> 00:25:14.040
and I might have to, because there's a very good chance that they're going to just die as soon as I try to turn this thing on.

00:25:14.040 --> 00:25:20.040
But now I'm going to put this other cap back.

00:25:20.040 --> 00:25:24.040
So the one, the caps that I was using, or that I am using for the most part,

00:25:24.040 --> 00:25:31.040
I ended up sourcing from an also glorious place known as the Vancouver Hack Space,

00:25:31.040 --> 00:25:37.040
would highly recommend going out and exploring your local hack space

00:25:37.040 --> 00:25:40.040
if you have the opportunity, and if one exists.

00:25:40.040 --> 00:25:48.040
They are fantastic places to meet other makers and find stuff that normally you'd never find

00:25:48.040 --> 00:25:51.040
for any reasonable price,

00:25:51.040 --> 00:25:58.040
because often people will just bring in stuff that's kind of functional or just like old,

00:25:58.040 --> 00:26:01.040
but still very good.

00:26:01.040 --> 00:26:07.040
So the caps that I have, they're film capacitors, which are made by Philips,

00:26:07.040 --> 00:26:11.040
at least the ones that I'm using in this particular location,

00:26:11.040 --> 00:26:17.040
and they are very, very high quality capacitors.

00:26:17.040 --> 00:26:23.040
They'd probably go for several dollars a piece when they were new at least.

00:26:23.040 --> 00:26:30.040
Obviously, at this point in their lifespan, data sheets don't exist for them anymore,

00:26:30.040 --> 00:26:36.040
so I would take hazarded guess that, okay, this isn't hot enough.

00:26:36.040 --> 00:26:41.040
They're not going to sell for nearly that much anymore. Also, they're hilariously over-spec for what I'm using them for,

00:26:41.040 --> 00:26:44.040
because they're rated for like 600 volts, or something like that.

00:26:44.040 --> 00:26:50.040
I don't remember the exact number, but it's like hilariously large.

00:26:50.040 --> 00:26:55.040
And so, entertainingly over-spec for what I'm using them for,

00:26:55.040 --> 00:27:01.040
but come on, you can do it.

00:27:01.040 --> 00:27:12.040
Come on, get out of there. Hello, excuse me.

00:27:12.040 --> 00:27:19.040
Come on, why?

00:27:19.040 --> 00:27:24.040
Thank you. Why, that was so difficult.

00:27:24.040 --> 00:27:37.040
I have no idea.

00:27:37.040 --> 00:27:43.040
Now I have a not so fun time of trying to solder this in.

00:27:43.040 --> 00:27:47.040
Mostly because I don't want to try to go full tilt right off the cuff,

00:27:47.040 --> 00:27:51.040
given the amount of power I'm working with here.

00:27:51.040 --> 00:27:56.040
If something goes wrong, it can go very wrong very fast.

00:27:56.040 --> 00:28:01.040
So I have this standard power inlet.

00:28:01.040 --> 00:28:06.040
I have a bunch of connectors I'm going to take.

00:28:06.040 --> 00:28:09.040
So here's going to be my switch.

00:28:09.040 --> 00:28:16.040
I have one output side where I'm connecting the two different sides of the switch to my rectifier.

00:28:16.040 --> 00:28:22.040
So this can handle three phase, but obviously if you put two phases into it, that'll work too.

00:28:22.040 --> 00:28:26.040
This is actually out from, normally used for welders.

00:28:26.040 --> 00:28:32.040
So you have your three phases in, and then you have a negative and positive out, and that's DC out.

00:28:32.040 --> 00:28:37.040
So on this side is my two separate inlets.

00:28:37.040 --> 00:28:41.040
So these are fully isolated from each other.

00:28:41.040 --> 00:28:50.040
What this switch does is it switches from either having my single phase power in or my three phase power in.

00:28:50.040 --> 00:28:57.040
This I'm probably just going to leave disconnected initially because I don't want to try to connect this thing up to three phase right away.

00:28:57.040 --> 00:29:06.040
I'm going to take one of my ground conductors and take that third pin from this inlet and just connect it to the chassis.

00:29:06.040 --> 00:29:12.040
And then this is going to be my live in neutral wire that go into my switch.

00:29:12.040 --> 00:29:23.040
And then depending on which setting it's in, either this three phase is connected to the output or exclusive or the single phase is connected.

00:29:23.040 --> 00:29:30.040
So this allows me to switch between the two if I want to, when I want to, because that's going to happen.

00:29:30.040 --> 00:29:34.040
These are some chocktastic, I think 10 gauge.

00:29:34.040 --> 00:29:38.040
So three by 10, three by 12, 12 gauge.

00:29:38.040 --> 00:29:41.040
So these are 12 gauge wire.

00:29:41.040 --> 00:29:45.040
These won't die.

00:29:45.040 --> 00:29:53.040
None of the circuits that we have that I have access to would actually over, this is the wrong crimper.

00:29:53.040 --> 00:29:58.040
Well, that's unfortunate.

00:29:58.040 --> 00:30:01.040
Time to do the giant.

00:30:01.040 --> 00:30:06.040
Yeah, I will actually do this properly and not just use a pair of pliers to cut this.

00:30:06.040 --> 00:30:10.040
So, so during this up, I'm not going to lie.

00:30:10.040 --> 00:30:13.040
It is going to be kind of janky.

00:30:13.040 --> 00:30:17.040
Let's see. Is this going to just line up nicely?

00:30:17.040 --> 00:30:22.040
Looks like it might.

00:30:22.040 --> 00:30:28.040
Okay, well, I'm glad I looked at the other side of this first.

00:30:28.040 --> 00:30:40.040
So if you look over here, I have some hilariously tall spikes of solder that I'm going to have to get rid of if I'm going to have a chance and heck of actually getting this cap in.

00:30:40.040 --> 00:30:45.040
So I'm going to do some good wick.

00:30:45.040 --> 00:30:54.040
Good wick and get rid of that first before even considering getting the cap anywhere near here.

00:30:54.040 --> 00:30:58.040
Okay, top side is reasonable.

00:30:58.040 --> 00:31:02.040
Over to the bottom side.

00:31:02.040 --> 00:31:09.040
I'll do one pass on this side too, hoping that it'll get most of the solder out, but I suspect that that's just not going to happen.

00:31:09.040 --> 00:31:19.040
And I'm going to have to dance around trying to melt part of the solder or one half of the solder and rocking the capacitor in,

00:31:19.040 --> 00:31:29.040
which I'd really rather not do, but I don't think I'm going to have an option for this particular instance.

00:31:29.040 --> 00:31:34.040
Come on.

00:31:34.040 --> 00:31:40.040
Okay, well, it just didn't work.

00:31:40.040 --> 00:31:46.040
So though I'm trying to remove solder,

00:31:46.040 --> 00:31:53.040
so though I'm trying to remove solder here, putting a little bit of solder on the iron before you try to apply this down.

00:31:53.040 --> 00:31:56.040
This applies to doing any soldering in general.

00:31:56.040 --> 00:31:59.040
If you have some solder on the iron first,

00:31:59.040 --> 00:32:07.040
it allows temperature to go from the iron to whatever you're working on a lot easier.

00:32:07.040 --> 00:32:11.040
It's just weird thermodynamics shenanigans.

00:32:11.040 --> 00:32:19.040
Oh, that actually worked pretty well. Essentially, the molten solder wicks onto the part you're,

00:32:19.040 --> 00:32:25.040
and like interfaces with the part you're trying to melt or solder to a lot better than just the bare iron.

00:32:25.040 --> 00:32:29.040
So if you can do it,

00:32:29.040 --> 00:32:36.040
have your iron just like with a little bit of solder on the tip.

00:32:36.040 --> 00:32:42.040
Wherever you're trying to solder,

00:32:42.040 --> 00:32:54.040
your life will be a lot easier.

00:32:54.040 --> 00:32:59.040
Okay, well, I didn't quite do what I sought out to.

00:32:59.040 --> 00:33:04.040
And unfortunately, there's still some solder in those holes,

00:33:04.040 --> 00:33:08.040
which sucks, so you can see there's still some on this hole.

00:33:08.040 --> 00:33:18.040
This you can actually kind of see through. So that was what I was hoping for for both of them, but it did quite pan out.

00:33:18.040 --> 00:33:23.040
Now what I get to do is do some cleanup.

00:33:23.040 --> 00:33:30.040
Though this isn't fully necessary, I would rather just do it if I can.

00:33:30.040 --> 00:33:35.040
So this is just electronics grade, isopropyl alcohol.

00:33:35.040 --> 00:33:45.040
The Goodwick that I was using, it has flux integrated into the copper braid,

00:33:45.040 --> 00:33:52.040
which deposits when you're rubbing it off so you can kind of see that gross brown color.

00:33:52.040 --> 00:33:56.040
That's the flux that's in the copper braid.

00:33:56.040 --> 00:34:01.040
Also some of that would have been from the solder as well.

00:34:01.040 --> 00:34:07.040
It helps prevent oxide buildup when you're soldering and allows you to build a better joint.

00:34:07.040 --> 00:34:12.040
Or in the case of the copper braid, it allows it to wick better.

00:34:12.040 --> 00:34:19.040
But in general, I would suggest cleaning it off.

00:34:19.040 --> 00:34:22.040
Though depending on your circuit, it probably doesn't matter,

00:34:22.040 --> 00:34:26.040
especially if it's something like this, it really doesn't matter.

00:34:26.040 --> 00:34:31.040
Because this is a personal project, no critical functions,

00:34:31.040 --> 00:34:39.040
nothing that's super super super sensitive to specific conditions.

00:34:39.040 --> 00:34:45.040
So flux in general is not the most pleasant substance to work with.

00:34:45.040 --> 00:34:52.040
Like it's not great for you, is what I mean.

00:34:52.040 --> 00:34:56.040
Okay, so here comes the fun part.

00:34:56.040 --> 00:35:01.040
So here's my capacitor, it needs to go in there.

00:35:01.040 --> 00:35:09.040
Let's talk about rocking it in, which is going to be what I'm doing here.

00:35:09.040 --> 00:35:13.040
Essentially, I'm going to melt the solder on one side first

00:35:13.040 --> 00:35:20.040
and get that leg as far in as I can, and then try to get the other leg in after that.

00:35:20.040 --> 00:35:29.040
I'm actually going to use these like this here.

00:35:29.040 --> 00:35:39.040
This is going to be some jank, full disclosure.

00:35:39.040 --> 00:35:45.040
But you know, such is life. That's why you're here to watch me, or me and or Linus,

00:35:45.040 --> 00:35:50.040
and or whomever else struggle with some sketch.

00:35:50.040 --> 00:36:01.040
Okay, so let's get that solder in there.

00:36:01.040 --> 00:36:05.040
Come on, A-O. So there it popped through.

00:36:05.040 --> 00:36:11.040
Now I get to do the other side. Actually, I'm going to adjust this backside a little.

00:36:11.040 --> 00:36:14.040
A-O success. Okay, so I got it through almost sets.

00:36:14.040 --> 00:36:18.040
Yay!

00:36:18.040 --> 00:36:28.040
Now my life gets a little bit easier. Okay, so now I'm just going to clean up this solder joint.

00:36:28.040 --> 00:36:34.040
Because though this works, I'd rather get a slightly better connection

00:36:34.040 --> 00:36:37.040
than just like the jamming it through connection.

00:36:37.040 --> 00:36:45.040
Okay, so those joints are a lot cleaner now, and in general, just a lot better.

00:36:45.040 --> 00:36:51.040
So, now comes the next jank.

00:36:51.040 --> 00:36:58.040
I'm probably going to trim those leads off later, but that's a later endeavor.

00:36:58.040 --> 00:37:04.040
That's for these.

00:37:04.040 --> 00:37:08.040
Oh, wait, what?

00:37:08.040 --> 00:37:12.040
Did I part? Okay, time for some snoopy.

00:37:12.040 --> 00:37:21.040
Sorry, Molex. Love your indexing features, but bye.

00:37:21.040 --> 00:37:25.040
So it looks like I got this right on one of them and wrong on the other.

00:37:25.040 --> 00:37:34.040
But also, so I know I checked the spec.

00:37:34.040 --> 00:37:40.040
So this is not Molex. Not the same as PCIe.

00:37:40.040 --> 00:37:44.040
So I learned today the classic.

00:37:44.040 --> 00:37:51.040
Because why would a standard be standard, right?

00:37:51.040 --> 00:38:01.040
Alright, so I sourced this nice 4U rack mount case for, let's just say, very cheap from some online retailer.

00:38:01.040 --> 00:38:09.040
Sorry, not online retailer. Online marketplace, which is going to act as my enclosure for my induction heater.

00:38:09.040 --> 00:38:21.040
I have a lot of my other components around me, around here with me as well, including my capacitor, my smoothing capacitor for after the rectifier.

00:38:21.040 --> 00:38:26.040
My three phase rectifier that's designed for welders.

00:38:26.040 --> 00:38:35.040
A nice little switch that is going to act as my switch between three phase power in and single phase power in.

00:38:35.040 --> 00:38:44.040
I'll start off using single phase power in and eventually I want to allow myself the headroom to switch to three phase in the long run.

00:38:44.040 --> 00:38:49.040
Just to allow a lot more power and to heat up and melt a lot more metal.

00:38:49.040 --> 00:38:59.040
Both bigger and different types like possibly copper or aluminum to melt those down and possibly do some casting or something else like that in the future.

00:38:59.040 --> 00:39:05.040
With a lot of my components, I have over-respect them to heck and back to allow for that.

00:39:05.040 --> 00:39:09.040
So this thing is rated up to 400 volts.

00:39:09.040 --> 00:39:14.040
It's a humongous capacitor that'll work for way more power than I'm going to put through this.

00:39:14.040 --> 00:39:24.040
This switch is rated for 400 plus volts, up to even I think 600 in some instances.

00:39:24.040 --> 00:39:29.040
This rectifier is good for three phase power.

00:39:29.040 --> 00:39:36.040
I can actually see the reading on it, but I'm pretty sure it's good for 220 or higher.

00:39:36.040 --> 00:39:45.040
And then obviously I have my tank capacitor, which is hilariously large and hilariously over-specified.

00:39:45.040 --> 00:39:51.040
I ended up doing the math on this thing and in theory, in theory,

00:39:51.040 --> 00:40:01.040
we could put the entire power, all of the power in lab two through this capacitor and it wouldn't even overpower it.

00:40:01.040 --> 00:40:06.040
Which is just entertaining and would never actually happen, but you know.

00:40:06.040 --> 00:40:14.040
I also got some breakers. So I'm planning on plugging this thing into a 20 amp circuit just to give myself a little bit more headroom current-wise.

00:40:14.040 --> 00:40:18.040
And these are 16 amp breakers.

00:40:18.040 --> 00:40:24.040
They are designed for a higher voltage rating, but that should be fine for what I'm doing.

00:40:24.040 --> 00:40:31.040
And this is just so these trips in the machine instead of having the breakers trip in the wall.

00:40:31.040 --> 00:40:38.040
It's a lot easier and cheaper to replace these things than it would be to have someone come in and replace the actual breakers in our electrical service.

00:40:38.040 --> 00:40:42.040
Or in any electrical service that I'm working with.

00:40:42.040 --> 00:40:47.040
Though breakers do have a pretty long lifespan, they do have a finite number of trips.

00:40:47.040 --> 00:40:52.040
So just giving again more headroom and more space ever around it.

00:40:52.040 --> 00:40:56.040
But I am going to switch gears and just tear this thing down.

00:40:56.040 --> 00:40:59.040
Alright, so at least the bulk of this is torn out now.

00:40:59.040 --> 00:41:06.040
I noticed there's a whole bunch of front buttons in here that I would love to be able to use.

00:41:06.040 --> 00:41:14.040
Unfortunately, literally every single one of the buttons on the front panel of this case is a momentary button.

00:41:15.040 --> 00:41:19.040
Which pretty much just means I can't turn it on and leave it on.

00:41:19.040 --> 00:41:24.040
Like for example, if I wanted to turn on the power supply for the control electronics,

00:41:24.040 --> 00:41:33.040
I'd need to have a non-momentary switch that connects sense line on the power supply to ground to keep it on.

00:41:33.040 --> 00:41:41.040
But everything on the front here is momentary, so I can't use literally any of them for that functionality.

00:41:41.040 --> 00:41:44.040
So I'm probably going to end up tearing out every single one of these buttons

00:41:44.040 --> 00:41:48.040
and replacing them with something that I can actually use in the long run.

00:41:48.040 --> 00:41:52.040
Which is kind of really irritating, honestly.

00:41:52.040 --> 00:41:57.040
If any of these were non-momentary, I could just hook that up to the power supply

00:41:57.040 --> 00:42:01.040
and I'd be done with that part, but no, couldn't be easy.

00:42:01.040 --> 00:42:07.040
But this case also has some integrated fans.

00:42:08.040 --> 00:42:11.040
Now these particular fans have some nice grills on the front.

00:42:11.040 --> 00:42:18.040
I was like, oh, very promising. Maybe these things are going to be strong enough just to supply all the cooling for the entire system.

00:42:18.040 --> 00:42:23.040
They are rated for 12 volts DC and 0.38 amps.

00:42:23.040 --> 00:42:26.040
And I turned them on and they're reasonable.

00:42:26.040 --> 00:42:35.040
But honestly, I don't think they're going to be able to dissipate enough energy out of this system to be able to keep it going.

00:42:35.040 --> 00:42:41.040
So I may end up swapping these out for some other fans that I have sourced

00:42:41.040 --> 00:42:45.040
slash will source to act as cooling for the whole system.

00:42:45.040 --> 00:42:51.040
And I may also end up moving this bracket somewhere else in the case that's more convenient for me.

00:42:51.040 --> 00:42:56.040
Because at the moment, I'm probably going to have power in

00:42:56.040 --> 00:43:03.040
and my mains voltage side in the back of the case over here

00:43:04.040 --> 00:43:10.040
with all of my breakers and everything in the back and both of my power ins,

00:43:10.040 --> 00:43:15.040
which for right now we're going to be two 120 volt power plugs,

00:43:15.040 --> 00:43:19.040
something similar to what they had on here in this one.

00:43:19.040 --> 00:43:26.040
But ideally something a little more beefy because this thing is fluffy and just not great.

00:43:26.040 --> 00:43:32.040
I'll use two of those, one that's for the power supply for the control electronics

00:43:32.040 --> 00:43:37.040
and then one that I will probably end up plugging into my variac

00:43:37.040 --> 00:43:43.040
to allow me to control how much voltage is going into the power side of the system.

00:43:43.040 --> 00:43:46.040
Now go through the rectifier and into this gigantic capacitor

00:43:46.040 --> 00:43:53.040
and eventually into the inverter and then out through the tubes or the copper piping.

00:43:53.040 --> 00:44:00.040
But I have a little more tear down to do, but at this point it's mostly done

00:44:00.040 --> 00:44:05.040
and it just kind of have to start laying out where I think everything's going to end up.

00:44:05.040 --> 00:44:09.040
But for now, I'm tearing out a whole bunch of buttons and all that fun stuff

00:44:09.040 --> 00:44:15.040
and then trying to figure out my more or less final layout in the case.

00:44:15.040 --> 00:44:18.040
So I've done a little bit of sizing up for some of the stuff.

00:44:18.040 --> 00:44:21.040
This is my breaker bar with some din rail.

00:44:21.040 --> 00:44:25.040
This is I'm going to use to mount this to this area.

00:44:25.040 --> 00:44:32.040
I'll end up doing some cuts across these bars so this will stick out

00:44:32.040 --> 00:44:38.040
and I'll also actually end up chopping these down so it fits more or less flush with this top area

00:44:38.040 --> 00:44:42.040
and I'll have something that comes up from the bottom that blocks the bottom too

00:44:42.040 --> 00:44:47.040
just to ensure that the high voltage isn't easily accessible from outside.

00:44:47.040 --> 00:44:50.040
But I have to chop these down first.

00:44:50.040 --> 00:44:55.040
Eventually I'll be putting some brackets and risers or some bolts through here

00:44:55.040 --> 00:45:01.040
with spacers to hold this off and hold this against this piece, these pieces in here.

00:45:01.040 --> 00:45:07.040
And I may actually end up welding the bottom of these PCIe covers to the base

00:45:07.040 --> 00:45:14.040
just to beef up the contact between them to make sure that these breakers don't move around too much.

00:45:14.040 --> 00:45:20.040
For now, off to the bandsaw. So I like our bandsaw quite a bit since it's been tuned up and works a ton better.

00:45:20.040 --> 00:45:26.040
One unfortunate downside with cutting this particular rail is it leaves some disgustingly sharp corners and edges on here

00:45:26.040 --> 00:45:31.040
so I'm actually going to take this to our grinder and sanding setup and round off these edges

00:45:31.040 --> 00:45:36.040
just to make sure that there's nothing sharp that someone could cut themselves on if they weren't paying attention.

00:45:36.040 --> 00:45:40.040
Okay, so I ended up finding a very convenient place for the switch.

00:45:41.040 --> 00:45:46.040
It's particularly nice in this instance because I don't actually even need to remove these cross struts.

00:45:46.040 --> 00:45:55.040
These can actually just stay put and I can just clamp this onto those to give me all the mechanical strength I'd need for this switch.

00:45:55.040 --> 00:46:05.040
And this is again to switch in between using three phase power in versus two phase power in

00:46:05.040 --> 00:46:12.040
if I ever end up doing that. But initially this is just going to act as an on off switch for the circuit.

00:46:12.040 --> 00:46:18.040
So this is for the power side I guess to be more specific.

00:46:18.040 --> 00:46:23.040
So this is very convenient.

00:46:23.040 --> 00:46:27.040
Alright, and I have another switch.

00:46:27.040 --> 00:46:31.040
So that's perfect.

00:46:31.040 --> 00:46:35.040
I have my two 12 gauge wires coming out

00:46:35.040 --> 00:46:43.040
and these are going to be my power in for the time being.

00:46:48.040 --> 00:46:53.040
And then I'll pull power out at the bottom.

00:46:54.040 --> 00:47:09.040
So here is my two cables for my one 10 or single phase power in that goes into the side

00:47:09.040 --> 00:47:13.040
and then power is going to come out the bottom, go across.

00:47:13.040 --> 00:47:19.040
Go across immediately to the breaker and then that'll go into the rest of the circuit.

00:47:19.040 --> 00:47:25.040
Alright, so I have located where I want the breaker to sit.

00:47:25.040 --> 00:47:28.040
And of course I moved it very far away.

00:47:28.040 --> 00:47:31.040
So I have my breaker up my little breaker set.

00:47:31.040 --> 00:47:34.040
I want to put it right in here.

00:47:34.040 --> 00:47:40.040
So there on the other side and then I'll mount some holes in these two plates.

00:47:40.040 --> 00:47:47.040
That'll hold this entire assembly against here and I'll put some support brackets above and below.

00:47:48.040 --> 00:47:52.040
Just to make sure that no one can poke anything in there.

00:47:52.040 --> 00:48:01.040
And electrocute or give themselves a very nasty electric shock to be more specific.

00:48:01.040 --> 00:48:06.040
But to do that I have to remove some metal.

00:48:06.040 --> 00:48:12.040
In comes small air powered rotary tool.

00:48:13.040 --> 00:48:19.040
Which is kind of just a little bit nicer to handle and work with than an angle grinder.

00:48:19.040 --> 00:48:25.040
Especially in somewhere this size. Though I may very swiftly regret that decision.

00:48:28.040 --> 00:48:32.040
You'll certainly find out just as I find out here.

00:48:32.040 --> 00:48:39.040
I'm just going to slap some cardboard back here just to protect that area up there.

00:48:40.040 --> 00:48:44.040
Not that I would recommend doing this particular endeavor.

00:48:44.040 --> 00:48:47.040
Because cardboard is kind of flammable.

00:48:47.040 --> 00:48:51.040
And I'm going to be tossing some sparks.

00:48:51.040 --> 00:48:58.040
Alright, time to see how immediately I regret this decision.

00:48:58.040 --> 00:49:03.040
Very immediately. Shuffle shuffle shuffle shuffle.

00:49:03.040 --> 00:49:08.040
So I need to actually be able to cut.

00:49:08.040 --> 00:49:11.040
This needs to overhang.

00:49:11.040 --> 00:49:15.040
And you can't see anything anymore.

00:49:15.040 --> 00:49:17.040
Let's put you right there.

00:49:18.040 --> 00:49:19.040
And now.

00:49:21.040 --> 00:49:24.040
Make sure it's too smooth out of the way.

00:49:26.040 --> 00:49:27.040
Alright.

00:49:30.040 --> 00:49:32.040
Vroom vroom. Vroom vroom.

00:49:36.040 --> 00:49:38.040
Okay, that's fun.

00:49:40.040 --> 00:49:47.040
The more you know. So this turns out this little middle plate is literally just attached by this one screw.

00:49:49.040 --> 00:49:53.040
So I very easily could have just undone that to remove it.

00:49:53.040 --> 00:49:57.040
Details, details, details.

00:49:57.040 --> 00:50:01.040
This one is attached to the rest of the plate though.

00:50:01.040 --> 00:50:05.040
So that still would have had to come out anyway.

00:50:06.040 --> 00:50:09.040
Oh, that's the classic. Okay.

00:50:09.040 --> 00:50:10.040
Time to take out the top.

00:50:15.040 --> 00:50:18.040
And it's gone. Fit check.

00:50:19.040 --> 00:50:21.040
Fit check fit check fit check.

00:50:22.040 --> 00:50:29.040
It fits, it fits, it fits, it fits. That's actually a relative, well, that's higher than I would like honestly.

00:50:30.040 --> 00:50:42.040
But it'll do. So now I just have to make a bottom plate that covers this and then trim down the top to cover this top piece.

00:50:42.040 --> 00:50:45.040
In the long run, I will need to access.

00:50:46.040 --> 00:50:51.040
Actually, no, I won't. Once it's assembled, all of these can just be left as is.

00:50:51.040 --> 00:50:55.040
So how we'll actually do this is I'll wire everything up.

00:50:55.040 --> 00:51:01.040
I'll drive fit everything, make sure that my wire lengths are long enough and there's enough stress relief in any of the cables.

00:51:01.040 --> 00:51:16.040
I'm not going to damage anything. Then I will do the wiring, connect this to the plate, something like that with these extra little slots in the din rail.

00:51:17.040 --> 00:51:22.040
And then the covers will just be there right off the cuff.

00:51:22.040 --> 00:51:26.040
So I won't have to worry about anyone contacting any of these things in here.

00:51:26.040 --> 00:51:32.040
This actually gives me quite a bit of working room in the bottom to make sure that I have enough strain relief in the cable.

00:51:32.040 --> 00:51:38.040
So now I'm just going to round off those edges and then should be good to go.

00:51:38.040 --> 00:51:44.040
Alright, so this thing's all closed up. I'm calling it for the day because it's late o'clock.

00:51:44.040 --> 00:51:51.040
Hopefully I'll be able to get the rest of the power electronics more or less laid out in here.

00:51:51.040 --> 00:51:55.040
And then I can start figuring out where I want all the control circuitry to end up.

00:51:55.040 --> 00:52:02.040
And then I get to start figuring out where all the water cooling is going to go, which is going to be a mess.

00:52:02.040 --> 00:52:05.040
That's certainly going to be a heck of a time.

00:52:05.040 --> 00:52:10.040
And probably not going to be a Linus thing because I would like to have a boss at the end of this video still.

00:52:10.040 --> 00:52:17.040
And there's enough stuff in here that if it's powered on and I didn't do my job correctly, it could kill you.

00:52:17.040 --> 00:52:21.040
So that's fun. Anyway, to the next day.

00:52:23.040 --> 00:52:28.040
Something I realized while I was about to try to weld up a couple of these together to make a block for this is

00:52:28.040 --> 00:52:34.040
if I actually just cut one more of these out, I can center the breakers and have material on both sides.

00:52:34.040 --> 00:52:40.040
So I don't have to have a top piece and a bottom piece, which will just make my life quite a bit easier in the long run.

00:52:40.040 --> 00:52:45.040
I'll end up having to chop off a bit more of the material in here with an angle grinder.

00:52:45.040 --> 00:52:48.040
But honestly, that's really not that big of a deal.

00:52:48.040 --> 00:52:56.040
I'll probably end up taking this side off here and removing this one rather than going this way and moving closer to the inputs

00:52:56.040 --> 00:53:00.040
just to give myself space for a bigger input down the road.

00:53:00.040 --> 00:53:03.040
But now off to the welder.

00:53:03.040 --> 00:53:10.040
I know you're not going to be able to see a ton of this, but I just want to get this welded up and have these relatively straight.

00:53:11.040 --> 00:53:20.040
It doesn't matter too much because at least from what I can tell, there's a fair bit of wiggle room in the actual box or in the actual case.

00:53:20.040 --> 00:53:26.040
So I can have them relatively close together and still be a-okay.

00:53:27.040 --> 00:53:32.040
But time for 10 nips.

00:53:38.040 --> 00:53:45.040
Also be careful. Even if it doesn't look hot, it's probably ridiculously hot after welding.

00:53:45.040 --> 00:53:50.040
Anything that you're welding is going to be smoking.

00:53:51.040 --> 00:54:00.040
Ask me how I know that that is a thing because I totally haven't done it to myself several times.

00:54:00.040 --> 00:54:07.040
Or I just burned the bejesus out of my hand without realizing that it's going to be really hot.

00:54:21.040 --> 00:54:29.040
Now that mystery metal coating is off, I can go up and finish welding along this full seam.

00:54:29.040 --> 00:54:35.040
Looking at how this first weld panned out, I added some filler material in all three of these.

00:54:35.040 --> 00:54:43.040
I also don't have any filler material that's properly thin enough for this thickness of weld.

00:54:44.040 --> 00:54:49.040
I ended up just kind of welding these two pieces together without any filler at all,

00:54:49.040 --> 00:54:54.040
which might be what I try to do for the rest of this because that seemed to pan out a lot better.

00:54:54.040 --> 00:55:02.040
I'm going to start by trying to join these top pieces together just to give a little bit more structure to the top section.

00:55:02.040 --> 00:55:08.040
Then I'll do a full weld along this entire seam just for extra structure.

00:55:08.040 --> 00:55:14.040
Then eventually I'll take out this chunk in the middle with an angle grinder or something similar to that.

00:55:14.040 --> 00:55:18.040
Back to the welding. My favorite.

00:55:23.040 --> 00:55:26.040
That wasn't atrocious. It was not good.

00:55:26.040 --> 00:55:30.040
To any welder, you know I am not doing very well.

00:55:30.040 --> 00:55:35.040
But for what I need, it's good enough.

00:55:35.040 --> 00:55:43.040
I may not do the full joint across because, holy moly, is this thing warping like nobody's freaking business.

00:55:43.040 --> 00:55:47.040
Just because it's so thin.

00:55:47.040 --> 00:55:53.040
And honestly, for what I need this thing to do, this is probably good enough.

00:55:53.040 --> 00:55:59.040
Like that's not going to give. Did some nice sandblasting and it's very shiny.

00:55:59.040 --> 00:56:08.040
It's still warped as heck, but yeah, this is thin enough that that's really not that big of a deal.

00:56:08.040 --> 00:56:13.040
Let's see, so I've got a nice warp in that direction.

00:56:13.040 --> 00:56:19.040
That's probably going to be a good part from that.

00:56:19.040 --> 00:56:24.040
You know what, let's just see if it lines up before I mess around with that too much.

00:56:24.040 --> 00:56:32.040
If it doesn't line up, I'm going to have to readdress my, figure out another plan.

00:56:32.040 --> 00:56:38.040
Okay, let's pop that out. Take that out.

00:56:38.040 --> 00:56:41.040
Put that down.

00:56:41.040 --> 00:56:47.040
Holy moly, is that bent a heck?

00:56:47.040 --> 00:56:51.040
Oh, that sounded like a weld breaking.

00:56:51.040 --> 00:57:00.040
Because it probably was a weld breaking.

00:57:00.040 --> 00:57:05.040
Aha, I found a problem.

00:57:05.040 --> 00:57:11.040
So the bottom of each one I put too close together so it won't fit into all three slots.

00:57:11.040 --> 00:57:16.040
That sucks.

00:57:16.040 --> 00:57:23.040
I'm with the tops. The tops will work honestly, like they do not have to be great.

00:57:23.040 --> 00:57:28.040
If it lines up with two, that's way more than good enough.

00:57:28.040 --> 00:57:35.040
So I'm going to take this to the hammering plate, better known as our welding bench.

00:57:35.040 --> 00:57:38.040
Actually our grinding bench because it's way thicker.

00:57:38.040 --> 00:57:42.040
Give it a good couple of whacks to flatten it out.

00:57:42.040 --> 00:57:48.040
And then I'm going to take some of these edges, these bottoms and just thin them out.

00:57:48.040 --> 00:57:53.040
Just to make my life a little bit easier so I don't have to re-weld it.

00:57:53.040 --> 00:58:00.040
Because the nice thing is I can just make these thinner and honestly for this it really doesn't matter.

00:58:00.040 --> 00:58:03.040
It is really quite irrelevant.

00:58:03.040 --> 00:58:10.040
I shortened up all of these tabs a little bit and gave these a good couple of whacks to really get it a lot flatter.

00:58:10.040 --> 00:58:15.040
It's still not flat, but again for this it really doesn't matter.

00:58:15.040 --> 00:58:19.040
And hey, oh that'll do don't care.

00:58:19.040 --> 00:58:30.040
Sorry Shrek. But I have one, two and a bit roughly kind of screw holes I can put into.

00:58:30.040 --> 00:58:36.040
But no one is never going to bolt to anything regardless because I promptly removed that part without realizing it.

00:58:36.040 --> 00:58:45.040
So time to take some more angle grinder slash cut off disc to this, trim all of these down.

00:58:45.040 --> 00:58:55.040
And then, yeah get in there ever so slowly.

00:58:55.040 --> 00:59:06.040
Just for sanity's sake.

00:59:06.040 --> 00:59:18.040
Alright, get to use some of my new favorite tools.

00:59:18.040 --> 00:59:21.040
Our air tools are working really well for me honestly.

00:59:21.040 --> 00:59:29.040
I'm pretty stoked with how well that's gone or with how well they're actually suiting me and what I need.

00:59:29.040 --> 00:59:41.040
But for anyone who's taking notes, these are all from the wood PC way back.

01:00:03.040 --> 01:00:11.040
Those who really don't know the wood PC was actually the first case mod I literally ever did.

01:00:11.040 --> 01:00:19.040
Yeah, the first fit I ever did was at work with a person from Germany and it was super fun.

01:00:19.040 --> 01:00:25.040
But yeah, that was an absolute blast.

01:00:25.040 --> 01:00:30.040
I should go close to this.

01:00:30.040 --> 01:00:42.040
Yes, yes, yes.

01:00:42.040 --> 01:00:50.040
This is going to be a tall glass of B. Roy Jenkins.

01:00:50.040 --> 01:01:01.040
Okay, good enough.

01:01:01.040 --> 01:01:09.040
Oh man, this thing's getting freaking heavy.

01:01:09.040 --> 01:01:21.040
Particularly a fan of this, but you know, such as life.

01:01:21.040 --> 01:01:25.040
Okay, I don't like how many metal shavings I put in there.

01:01:25.040 --> 01:01:35.040
After a tremendous amount of jank, most of the holes cut out.

01:01:35.040 --> 01:01:41.040
Time to see if it actually frickin fits because that's kind of the whole point.

01:01:41.040 --> 01:01:46.040
All right, so my my gap here looks really big.

01:01:46.040 --> 01:01:53.040
However, my gap here doesn't, which I'm just now realizing.

01:01:53.040 --> 01:02:00.040
That's why.

01:02:00.040 --> 01:02:03.040
Okay.

01:02:03.040 --> 01:02:13.040
Well, that's kind of entertaining in a really sad way.

01:02:13.040 --> 01:02:25.040
Frickin whoops.

01:02:25.040 --> 01:02:41.040
I think I'm just going to go with it.

01:02:41.040 --> 01:02:48.040
I think I'm just going to go with it and mount it sideways because it's going to be a lot easier to just leave it as is.

01:02:48.040 --> 01:02:54.040
Then try to fix this gong show because I don't want a whole bunch of space around the breaker.

01:02:54.040 --> 01:03:03.040
Because that means that you can go in and touch the frickin screws, which are, I'm pretty sure, not certain connected to the little frickin wires.

01:03:03.040 --> 01:03:07.040
While it's on and closed, which I really don't want.

01:03:07.040 --> 01:03:18.040
So, time to figure out how to mount the din rail to this in the wrong orientation, I guess.

01:03:18.040 --> 01:03:27.040
Not ideal, but it'll work. Let's go into a little adventure of why I should have measured more times than I cut.

01:03:27.040 --> 01:03:38.040
So initially, I looked at this hole right here and was like, oh, that's like perfect because it was one of the mounts originally for a piece that was right here and eventually went away.

01:03:38.040 --> 01:03:49.040
So I cut it out bigger so I could use this nice little flat nut thing tube, whatever, can't remember the name of it, so it would actually fit in.

01:03:49.040 --> 01:03:58.040
Unfortunately for me, we don't have any screws that are long enough to match.

01:03:58.040 --> 01:04:02.040
So, okay, cool. Well, I guess I'm boned there.

01:04:02.040 --> 01:04:09.040
I ended up doing more searching for a bunch of other longer bolts and we don't actually have any here that are M4.

01:04:09.040 --> 01:04:22.040
So that's fun. I then drilled a lower hole here, which works perfectly and I can actually screw it in because the extra space from here to here actually lets this mate with the screw.

01:04:22.040 --> 01:04:25.040
So that one works perfectly.

01:04:25.040 --> 01:04:31.040
Came to the conclusion that, okay, cool, so I will need to put another hole up here.

01:04:31.040 --> 01:04:36.040
Unfortunately, it was probably going to interfere with this weld, which would suck.

01:04:36.040 --> 01:04:46.040
So I was like, okay, let's put it up as high and as close to this as we can, which works other than the fact this thing has a giant freaking lip on it.

01:04:46.040 --> 01:04:52.040
So now I need to trim off part of this so it'll sit flat and I can actually screw into it.

01:04:52.040 --> 01:04:56.040
The struggle is so real.

01:04:56.040 --> 01:04:59.040
My goodness, made a sad realization just now.

01:04:59.040 --> 01:05:08.040
Apparently, I didn't tighten the freaking nut on the bottom of this switch properly for at least this phase.

01:05:08.040 --> 01:05:13.040
So it just fell off, which is kind of really bad.

01:05:13.040 --> 01:05:29.040
I'm going to have to take this apart and access the bottom of this switch in order to resolve this.

01:05:29.040 --> 01:05:32.040
Oh, I just had a big realization.

01:05:32.040 --> 01:05:40.040
I should rotate this switch 90 degrees because then I can actually access all of the screw terminals.

01:05:40.040 --> 01:05:57.040
Okay, I was going to see if I can just take this entire metal plate or metal like GPI PCIe bracket set out because I think I can if I just remove a bunch of these screws and I think this entire plate will just come off.

01:05:57.040 --> 01:06:08.040
But with the sudden realization that I just had, I need to take this switch off again, which means taking all of the freaking screws and crap that holds it in.

01:06:08.040 --> 01:06:18.040
Taking them all off, taking this entire thing out, rotating it 90 degrees so I can access all of the screw terminals all the time and then going again.

01:06:18.040 --> 01:06:25.040
That will mean getting access to whatever side is on the bottom is going to suck.

01:06:25.040 --> 01:06:33.040
Actually, right now I'm wishing I had mounted this higher up, but too little too late on that one.

01:06:33.040 --> 01:06:40.040
So time for a little more time-lapse and a little more repeating work I've already done several times.

01:06:40.040 --> 01:06:52.040
Woo! While I was tightening down all of these screws again just to make sure that nothing comes loose ever again because that would be really bad.

01:06:52.040 --> 01:07:04.040
I cracked the switch. So I cracked the plastic housing on the back for the black phase, which is going to be one of the live phases.

01:07:04.040 --> 01:07:18.040
So now it clicks around whenever I move the cable because it's no longer holding it strong, like it's no longer holding it properly anymore.

01:07:18.040 --> 01:07:39.040
That's not ideal. Again, I think it's probably okay, but this is starting to get towards I only run one phase at a time and I just rewire it if I ever need to up how many phases I'm running.

01:07:39.040 --> 01:07:44.040
So I think that might just kill this switch.

01:07:44.040 --> 01:08:03.040
Probably remove this wire, the red phase entirely, and shift over the black phase, all of that wiring just for the sake of ease of reference.

01:08:03.040 --> 01:08:13.040
I'll still run three phase out probably, actually.

01:08:13.040 --> 01:08:19.040
Okay, I'm just going to use the red phase out entirely for now.

01:08:19.040 --> 01:08:25.040
That's extra complication for the entire circuit.

01:08:25.040 --> 01:08:30.040
So the screw is actually biting very well.

01:08:30.040 --> 01:08:42.040
What actually happened was, so if I understand this correctly, this screw bites into this sheet piece of metal behind it, not into this plastic housing.

01:08:42.040 --> 01:08:55.040
What actually cracked was as I was torquing this, this piece of bent metal goes into some of the internals, which means I probably need to check the status of this switch to see if it still works properly.

01:08:55.040 --> 01:09:04.040
One second while I find some testing equipment.

01:09:04.040 --> 01:09:09.040
So a nice multimeter, or a pretty good multimeter.

01:09:09.040 --> 01:09:22.040
Flick 117, true RMS meter, but honestly it can use whatever the F needs to be used for this because it really just needs to tell me if this thing is still behaving as a switch.

01:09:22.040 --> 01:09:29.040
It should. Being that it turns off when it's off and it turns on when it's on.

01:09:29.040 --> 01:09:34.040
I need to find where I ended up putting the post.

01:09:34.040 --> 01:09:37.040
Oh, it's in here. Oh yeah, it's attached.

01:09:37.040 --> 01:09:43.040
Okay, so let's see what state it's in right now.

01:09:43.040 --> 01:09:49.040
So, doot doot. Yeah, I know it's not perfect, but for what I'm doing it's fine.

01:09:49.040 --> 01:09:55.040
These are both input terminals. So if anything is shorting, I have a very big problem.

01:09:55.040 --> 01:09:59.040
No, thank goodness. That's very good news.

01:09:59.040 --> 01:10:03.040
Okay, so that's shorting as I would expect.

01:10:03.040 --> 01:10:07.040
And that and that perfect.

01:10:07.040 --> 01:10:11.040
I don't want to make sure these aren't connected.

01:10:11.040 --> 01:10:14.040
That would be really bad.

01:10:14.040 --> 01:10:18.040
Okay, so far so reasonable.

01:10:18.040 --> 01:10:25.040
One more little check-to-check to do first before saying it works.

01:10:25.040 --> 01:10:31.040
Wow, that is really hard to turn.

01:10:31.040 --> 01:10:39.040
Okay, so now it's in the other state which should have this two-phase power connected into the output side.

01:10:39.040 --> 01:10:44.040
Essentially it just shorts these two, this side or this side, not both.

01:10:44.040 --> 01:10:48.040
Again, continuity check.

01:10:48.040 --> 01:10:52.040
Looks good, looks good, looks good.

01:10:52.040 --> 01:10:56.040
Let's just do a little resistance check as well.

01:10:56.040 --> 01:11:03.040
Just for completeness, 0.4.

01:11:03.040 --> 01:11:06.040
That seems a little high.

01:11:06.040 --> 01:11:09.040
0.2, that's fine.

01:11:09.040 --> 01:11:14.040
0.2, that's actually marginally concerning.

01:11:14.040 --> 01:11:29.040
Okay, yeah, that was 0.2 as well. And then I will swap it back and just check that the other side, the resistances on the other side are roughly comparable to that.

01:11:29.040 --> 01:11:33.040
Okay, contact resistance, have mercy on me please.

01:11:33.040 --> 01:11:38.040
So, 0, 0.

01:11:38.040 --> 01:11:47.040
I need to go back and check the other side, 0.

01:11:47.040 --> 01:11:55.040
Realistically what I was probably measuring was just, actually can you even see the multimeter?

01:11:55.040 --> 01:11:58.040
Not really.

01:11:58.040 --> 01:12:01.040
Sorry about that.

01:12:02.040 --> 01:12:06.040
Okay, you probably can't read it, but just trust me.

01:12:06.040 --> 01:12:09.040
So, what was probably the issue?

01:12:09.040 --> 01:12:13.040
0.1, yeah, contact resistance.

01:12:13.040 --> 01:12:18.040
0.1 and 0.1.

01:12:18.040 --> 01:12:27.040
If you don't push hard enough, sometimes there's just a little bit of space and resistance in between the metal contact and the metal thing you're trying to measure.

01:12:27.040 --> 01:12:32.040
And if you're measuring really small resistances, that can actually make a huge difference.

01:12:32.040 --> 01:12:37.040
So, like if I don't press very hard at all, okay, well it's still low.

01:12:37.040 --> 01:12:42.040
But let's see.

01:12:42.040 --> 01:12:56.040
See how that, it's just jumping around a whole bunch. It's just, you want to make sure you're breaking through any like random oxide layers or gunk or whatever that's on the surface of your conductor.

01:12:56.040 --> 01:12:59.040
If you're trying to measure resistance.

01:12:59.040 --> 01:13:02.040
Unless you're trying to measure the resistance out of the gunk.

01:13:02.040 --> 01:13:10.040
But that's a whole different ball game and honestly you probably shouldn't use a multimeter for that.

01:13:10.040 --> 01:13:18.040
A better way to do that would be like an ESD tester or something like that where it generates a really high voltage and determines how quickly it breaks through and breaks down.

01:13:18.040 --> 01:13:26.040
That's a much better way of trying to test like surface resistance rather than like actual resistance between metals.

01:13:26.040 --> 01:13:32.040
But anyway, now that, oh, did I just tighten that down and then not have the, yes I did, okay.

01:13:32.040 --> 01:13:37.040
So I'm just going to ignore the red phase because too much work.

01:13:37.040 --> 01:13:45.040
At least out of the switch because I'm going to have to come back in here eventually regardless.

01:13:45.040 --> 01:13:50.040
And I kind of just don't care enough.

01:13:50.040 --> 01:13:59.040
Yeah, that one. Okay, so let's slap this down, ponder my life choices.

01:13:59.040 --> 01:14:02.040
Do I just want to put that in? Yeah, I kind of do.

01:14:02.040 --> 01:14:11.040
I'm just going to put this back in. So I managed to get this more or less wired up and connected to the input, albeit a little bit sketchily.

01:14:11.040 --> 01:14:14.040
But you know, part of this isn't sketchy.

01:14:14.040 --> 01:14:20.040
Also, I am not an electrician. Do not follow what I'm doing.

01:14:20.040 --> 01:14:25.040
I am going to be the only one using this or I will be around whenever it is being used.

01:14:25.040 --> 01:14:30.040
So if something decides to go wrong, I am the person who has wired it.

01:14:30.040 --> 01:14:40.040
I will be around it and I will have more or less a solid idea of what to do if something decides to go horribly wrong or something disconnects.

01:14:40.040 --> 01:14:44.040
I'm doing my best to be as safe as possible.

01:14:44.040 --> 01:14:47.040
That's why I have some 16 amp breakers in here.

01:14:47.040 --> 01:14:59.040
I plan to plug this into a 20 amp service, 20 amp 120 to start or 110 whatever lower power, lower voltage.

01:14:59.040 --> 01:15:07.040
So this should trip before anything in the wall trips should anything upstream from here go wrong downstream from here go wrong.

01:15:07.040 --> 01:15:13.040
Sorry. If anything upstream goes wrong, the breakers in the building should trip.

01:15:13.040 --> 01:15:21.040
Obviously the plan is to never have that happen, but I'm planning on grounding everything as you should.

01:15:21.040 --> 01:15:28.040
Making sure that the ground that comes in from either power service that's going to be running to here, whether the high power side or the low power side.

01:15:28.040 --> 01:15:36.040
Those grounds are connected to the chassis, which is not ideal in general because that means I'm going to have two separate grounds.

01:15:36.040 --> 01:15:41.040
They're connected together at this point creating a very large ground loop.

01:15:41.040 --> 01:15:44.040
We'll see if I end up having to address that or not.

01:15:44.040 --> 01:15:58.040
I may end up having to isolate the chassis ground on the power supply for the low power side from the high power.

01:15:58.040 --> 01:16:02.040
I am connecting the high power ground to the chassis.

01:16:02.040 --> 01:16:15.040
That is just happening. Technically speaking, it doesn't really matter which one is connected as long as one is, but I'm planning on connecting the high power ground to it just because I can.

01:16:15.040 --> 01:16:23.040
So the next thing I need to do is this is my full list of bridge rectifiers.

01:16:23.040 --> 01:16:36.040
So it's a three phase rectifier, takes three phase AC, connects it or pumps out DC from the AM minus and the KM plus.

01:16:36.040 --> 01:16:39.040
So this thing is going to need some cooling.

01:16:39.040 --> 01:16:50.040
I was debating using some other random heat sinks that I had, but I think this one is probably going to work the best as long as I make sure that the air flow path is flowing through this heat sink.

01:16:50.040 --> 01:16:57.040
I don't believe this should overheat. If it does overheat in the long run, then, you know, I'll cross that bridge when I get there.

01:16:57.040 --> 01:17:08.040
But for now, I need to drill some holes, make some connections here and then plop some thermal paste or thermal compound down in between this nice face here and this face here.

01:17:08.040 --> 01:17:15.040
I'll probably rough this up as well just to kind of get rid of all of the bumps and nicks and crap that have built up on this over time.

01:17:15.040 --> 01:17:28.040
And I'll bolt this down and make sure that the fins are in the direction of the main air flow, which I think is going to be either this direction or out here based on the fact that most of this back is currently solid.

01:17:28.040 --> 01:17:34.040
And then I will figure out a way to mount this to the chassis itself.

01:17:34.040 --> 01:17:41.040
While I was looking to try to mount this rectifier, I drilled a couple of holes, lined it all up. This all looks good.

01:17:41.040 --> 01:17:49.040
I was looking at connecting it in. There were a couple of thoughts I had. One of them was tapping this piece of aluminum, but I really don't like that.

01:17:49.040 --> 01:17:54.040
Aluminum threads are just, they work, but they're not great.

01:17:54.040 --> 01:18:00.040
Another thought was just to have a nut on the back here and tighten it down from the top.

01:18:00.040 --> 01:18:04.040
And then I had a dumb idea.

01:18:04.040 --> 01:18:09.040
We have some heat set inserts that are designed to go into plastic.

01:18:09.040 --> 01:18:20.040
We also have an arbor press. So I drilled out this hole a bit bigger than I would expect and the bottom of the heat set insert fits in.

01:18:20.040 --> 01:18:28.040
So I'm going to try pressing it and quickly probably realize how stupid of an idea this is.

01:18:28.040 --> 01:18:38.040
I'm going to put a nice little stop on the other side of here, just a piece of steel so it doesn't push through too far because it would, which I don't want.

01:18:38.040 --> 01:18:43.040
I want it to press in a little bit. This is really dumb and probably not going to work.

01:18:43.040 --> 01:18:46.040
But if it does work, heck yeah, bud.

01:18:46.040 --> 01:18:53.040
We'll see. I may actually end up drilling this hole out even a little bit bigger because this is not looking like it's probably going to work.

01:18:53.040 --> 01:18:58.040
But I'll try first and then fix it later.

01:18:59.040 --> 01:19:03.040
It's not ideal. So I've got a couple blocks of aluminum.

01:19:03.040 --> 01:19:06.040
Tactics, my stops.

01:19:06.040 --> 01:19:21.040
And let's just get you a little closer into this adventure of horrible ideas.

01:19:21.040 --> 01:19:42.040
In this episode, hoping that things don't go absolutely flying literally everywhere because there's a reasonable chance that this is going to fail hilariously and very not great.

01:19:42.040 --> 01:19:47.040
Okay, so on the press.

01:19:47.040 --> 01:19:52.040
Oh, yeah, that's not that's not happening.

01:19:52.040 --> 01:19:55.040
Oh, wait.

01:19:55.040 --> 01:20:00.040
Oh, wait, it bit.

01:20:00.040 --> 01:20:03.040
Okay. Okay. Wow.

01:20:03.040 --> 01:20:06.040
I'm a bit surprised.

01:20:06.040 --> 01:20:12.040
Okay. Let me qualify that it bit a little.

01:20:12.040 --> 01:20:18.040
Yeah, I can see where it where it actually bit into the aluminum.

01:20:18.040 --> 01:20:25.040
So I'll give it another go just for kicks.

01:20:25.040 --> 01:20:29.040
Because if this actually worked, that would be very entertaining.

01:20:29.040 --> 01:20:33.040
The other option here is actually just to pull it through with an with a bolt.

01:20:33.040 --> 01:20:54.040
And I may end up taking that approach if assuming if slash when this doesn't work.

01:20:54.040 --> 01:21:01.040
Well, I'll be damned that actually kind of worked.

01:21:01.040 --> 01:21:13.040
So it's about halfway through that part, which means I can give it another whack or two and it'll be well, I mean, it's permanently in there now.

01:21:13.040 --> 01:21:23.040
Let's let's say that I don't want to undersell what just actually happened.

01:21:23.040 --> 01:21:33.040
Yeah, that that that works.

01:21:33.040 --> 01:21:38.040
That's entertaining.

01:21:38.040 --> 01:21:43.040
Did not think that that would actually work.

01:21:43.040 --> 01:21:48.040
Also, as I will say five bajillion times on this project, this is dumb.

01:21:48.040 --> 01:21:52.040
There are way easier ways to do what I'm doing.

01:21:52.040 --> 01:21:55.040
It's just fun.

01:21:55.040 --> 01:22:02.040
Why am I doing this if not to have a hell of a good time messing around with Intel's money?

01:22:02.040 --> 01:22:15.040
Thank you Intel for enabling my gong show.

01:22:15.040 --> 01:22:20.040
That actually works.

01:22:20.040 --> 01:22:26.040
That's dumb. So I just whacked the piece of aluminum with the ever press a whole bunch of times.

01:22:26.040 --> 01:22:29.040
And I was like, oh, yeah, it's working super duper well.

01:22:29.040 --> 01:22:35.040
Like I have the heat set inserts like embedded into the top surface of the aluminum.

01:22:35.040 --> 01:22:46.040
Oh, it's the top surface of the aluminum that the side that the direct fire needs needs to connect to.

01:22:46.040 --> 01:22:54.040
So in my excitement that it worked, I shot myself in the photo a little bit.

01:22:54.040 --> 01:23:00.040
So I think I'm actually just going to toss this on the Tormach and just face this off.

01:23:00.040 --> 01:23:11.040
So close, but yet so far. And now that I'm back with a freshly faced off area, whoops, so close, but yet so far.

01:23:11.040 --> 01:23:16.040
This will actually meet relatively OK to this now.

01:23:16.040 --> 01:23:21.040
The keen item on you might notice that the surface finish on this looks like poop.

01:23:21.040 --> 01:23:25.040
That has nothing to do with the Tormach and everything to do with me being lazy.

01:23:25.040 --> 01:23:30.040
So this part when I bandsawed it is not at all square.

01:23:30.040 --> 01:23:36.040
So these two surfaces are not parallel to each other. So when I was clamping, it only actually held down like this part,

01:23:36.040 --> 01:23:43.040
which means this was all floppy and while I was machining and I got a ton of chatter on here.

01:23:43.040 --> 01:23:50.040
For this, it really doesn't matter. I'm probably going to rough this up with a bit of Scotch Brite anyway and then apply some thermal compound down.

01:23:50.040 --> 01:23:53.040
But just in case anyone was wondering.

01:23:53.040 --> 01:24:02.040
Now I'm starting to look at the gigantic capacitor and the IGBTs and how they're actually going to end up fitting in there

01:24:02.040 --> 01:24:10.040
and coupling to each other because this cap needs to be connected to these two pins on both of these IGBTs.

01:24:10.040 --> 01:24:17.040
There's also this cap here, which kind of just limits out and tries to eliminate as much inductance as possible on the quick switching

01:24:17.040 --> 01:24:22.040
right when it engages so it can pump as much current as possible immediately.

01:24:22.040 --> 01:24:27.040
I had a couple of thought issues.

01:24:27.040 --> 01:24:35.040
So originally when I had cat it up the brackets to connect these together, I had it schemed.

01:24:35.040 --> 01:24:45.040
So either this cap would be oriented like this or something like this or maybe like the IGBTs would be oriented up here or something.

01:24:45.040 --> 01:24:48.040
Or sorry, up here or something like that.

01:24:48.040 --> 01:24:54.040
But looking at the layout that I have in this case and how much height I have, that's just not going to work.

01:24:54.040 --> 01:24:59.040
This cap is going to have to be located in this orientation.

01:24:59.040 --> 01:25:03.040
Just an ideal but, you know, life.

01:25:03.040 --> 01:25:07.040
Which means I have a couple of potential options.

01:25:07.040 --> 01:25:12.040
The first of which is trying to bend some of the copper plate that I have.

01:25:12.040 --> 01:25:19.040
So I ended up collecting this pre-bent piece of copper that's like a quarter of an inch thick or so.

01:25:19.040 --> 01:25:25.040
I tried whacking it with a hammer to see if I could bend it anymore here and nothing happened at all.

01:25:25.040 --> 01:25:32.040
So this is not going to be an option because we don't have, I don't have access to the equipment to try to bend copper this thick.

01:25:32.040 --> 01:25:35.040
Certainly not this copper at least.

01:25:35.040 --> 01:25:38.040
So this is out the door.

01:25:38.040 --> 01:25:48.040
By extension and the other combination of flat into bend or into straight is going to be very difficult using purely copper.

01:25:48.040 --> 01:25:51.040
Because I can't bend it.

01:25:51.040 --> 01:26:00.040
But I had a realization that oh maybe, just maybe I can use these aluminum brackets that we have or that I have access to.

01:26:00.040 --> 01:26:12.040
Mount those onto each pin and then maybe just maybe the height of the copper would line up and it pretty much does almost bang on.

01:26:12.040 --> 01:26:22.040
So that's going to be my game plan is I need to cut down some of the hilarious piles of copper that I have collected.

01:26:22.040 --> 01:26:30.040
Machine out some holes to connect these together and make sure they are point together.

01:26:30.040 --> 01:26:35.040
Because the water block I bought for these is not that much bigger than these.

01:26:35.040 --> 01:26:40.040
So I don't have a ton of space to fiddle around with for clearance between these.

01:26:40.040 --> 01:26:45.040
And then I need to make the bars long enough that it extends out to about here.

01:26:45.040 --> 01:26:52.040
Then I can mount. I may end up bolting this down.

01:26:52.040 --> 01:27:01.040
But I also may end up just straight soldering the copper to the aluminum just because that's going to be a way better electrical and thermal connection.

01:27:01.040 --> 01:27:05.040
Although in this particular location the thermal connection is kind of relevant.

01:27:05.040 --> 01:27:15.040
But you know when I'm working with the power that I'm working with any kind of additional electrical resistance can actually make a really big difference to making things get ridiculously hot.

01:27:15.040 --> 01:27:27.040
So I'm probably going to test out I'm going to test out trying to solder some aluminum like this to a piece of copper to see how much I hate myself trying to do it.

01:27:27.040 --> 01:27:31.040
That's going to be a fun map gas experiment.

01:27:31.040 --> 01:27:41.040
I'll probably end up taking this piece and trying to solder on one of these or something similar-ish to this just to see how that works out.

01:27:41.040 --> 01:27:48.040
And I'll end up popping over to the welding bench and doing some fire brick shenanigans which will be good fun.

01:27:48.040 --> 01:27:52.040
So off to that I go. Over to the welding bench.

01:27:52.040 --> 01:28:11.040
I have some Scotch Brite just to rough up and clean up all the oxides that are on both the copper and on the aluminum to make sure that the solder has a reasonable chance of actually gripping.

01:28:11.040 --> 01:28:20.040
This is somewhat a process that you really want to be thorough and make sure you've really cleaned everything within an inch of its life.

01:28:20.040 --> 01:28:24.040
Otherwise you're going to not get a good bond at all.

01:28:24.040 --> 01:28:32.040
So you can see that this is nice and shiny. This obviously not so much. This has been oxidizing for a very long time.

01:28:32.040 --> 01:28:44.040
Now these naturally come to the best of my knowledge with a decent anodized layer on them which just, you know, in addition to natural oxidation which aluminum does it creates its own protective layer.

01:28:44.040 --> 01:28:50.040
This has an additional anodization step that makes that oxide layer thicker.

01:28:50.040 --> 01:28:58.040
And aluminum oxide specifically stuff that's used for anodization is actually really tough.

01:28:58.040 --> 01:29:02.040
And it kind of has a little bit of a dull finish on it.

01:29:02.040 --> 01:29:05.040
See if I can actually even operate it.

01:29:05.040 --> 01:29:14.040
So I'm not having a ton of luck. I'm actually going to take this over to the belt grinder and hit it there.

01:29:14.040 --> 01:29:19.040
Because I know that this will take it off.

01:29:19.040 --> 01:29:30.040
This is a great way to show what I was talking about.

01:29:30.040 --> 01:29:38.040
So you see how over here this is shiny. Like properly shiny. That's the bare aluminum metal.

01:29:38.040 --> 01:29:43.040
Whereas this stuff here, this is aluminum oxide. Specifically this is likely anodized on.

01:29:43.040 --> 01:29:51.040
And I'm pretty, I'm going to take a shot in the dark and guess that the anodized layer might actually be harder than this scotch bright.

01:29:51.040 --> 01:29:54.040
So it isn't able to break through it very easily.

01:29:54.040 --> 01:29:57.040
But taking it to the belt grinder, it's a lot more abrasive.

01:29:57.040 --> 01:30:02.040
And I think these are actually aluminum oxide sanding dis, sanding belts.

01:30:02.040 --> 01:30:05.040
So this will take it off without too much difficulty.

01:30:05.040 --> 01:30:09.040
So I'm going to take this back, take off the rest of this heavy oxide.

01:30:09.040 --> 01:30:15.040
And then I'll touch it up with the scotch bright, give them both an alcohol wipe down and then start trying to solder this together.

01:30:15.040 --> 01:30:23.040
Nice and shiny. So if I move this around in the light, it'll be shiny in different amounts depending on the orientation it's in.

01:30:23.040 --> 01:30:28.040
That's just because I was taking different angles and different passes to make sure I got all the anodization off.

01:30:28.040 --> 01:30:38.040
But now I'm going to rough it up a little bit more, make sure it's all nice and clean.

01:30:38.040 --> 01:30:42.040
Make sure all of that oxidation is gone.

01:30:42.040 --> 01:30:49.040
This little alcohol wipe. And then I'm moving this bottle of alcohol extraordinarily far away from me,

01:30:49.040 --> 01:30:57.040
including this rag that I just doused in a hilariously flammable liquid right next to a torch and a hot brick

01:30:57.040 --> 01:31:01.040
and all kinds of other things that are about to be extraordinarily high.

01:31:01.040 --> 01:31:05.040
Oh yeah, so there's all the dust and grossness that came off of the copper.

01:31:08.040 --> 01:31:11.040
Second pass is a lot more reasonable.

01:31:11.040 --> 01:31:14.040
In terms of the aluminum, I've already kind of cleaned it once.

01:31:14.040 --> 01:31:18.040
I'm fairly sure that it's purple, someone will probably correct me in the comments,

01:31:18.040 --> 01:31:24.040
that isopropyl actually causes some kind of additional take off of material from aluminum,

01:31:24.040 --> 01:31:34.040
because I've had times where I'm wiping aluminum down consistently and I'll consistently get a dirty colored rag when I'm doing it with isopropyl alcohol.

01:31:34.040 --> 01:31:41.040
So, I don't know, some weirdness.

01:31:41.040 --> 01:31:51.040
All right, this I'm fairly sure is flux, which will just make my life a lot less painful.

01:31:51.040 --> 01:31:56.040
Sunshade just prevents oxidization while the two metals are really, really hot,

01:31:56.040 --> 01:32:03.040
because as you heat something up, it will oxidize way faster.

01:32:03.040 --> 01:32:11.040
If there's anyone who's ever seen very hot steel or any other very hot metal, they'll know.

01:32:11.040 --> 01:32:19.040
And they can tell you that, oh boy, does it get an oxide layer real freaking fast.

01:32:19.040 --> 01:32:29.040
Okay, now here comes the adventure part, because I don't know if this is going to work.

01:32:29.040 --> 01:32:36.040
So I have some map gas, methyl, ath, acetyl, propane or something ridiculous like that.

01:32:36.040 --> 01:32:39.040
I can't remember, I looked it up at one point.

01:32:39.040 --> 01:32:46.040
It burns really hot.

01:32:46.040 --> 01:32:55.040
Yeah, it burns really hot, so it should have no issue getting this thing hot enough to solder together.

01:32:55.040 --> 01:33:01.040
I'm just using some plumbing lead-free solder.

01:33:01.040 --> 01:33:04.040
I could easily use leaded solder, and honestly, it would make my life easier,

01:33:04.040 --> 01:33:07.040
but I kind of just don't want to.

01:33:07.040 --> 01:33:11.040
Lead, I'd just rather avoid it if I can.

01:33:11.040 --> 01:33:18.040
So, let's see how well this goes.

01:33:18.040 --> 01:33:23.040
For this, I want to heat up the bar, copper, and the aluminum part itself.

01:33:23.040 --> 01:33:26.040
Okay, the box is starting to get liquid.

01:33:26.040 --> 01:33:33.040
Okay, so that didn't work. The reason I can tell is as I was dragging that solder along the joint,

01:33:33.040 --> 01:33:40.040
what I wanted it to do was I wanted it to pull in between the aluminum and the copper.

01:33:40.040 --> 01:33:48.040
It did not do that, which likely means...

01:33:48.040 --> 01:33:53.040
Oh, I should be doing this, probably, trying to do this sideways.

01:33:53.040 --> 01:33:56.040
I didn't treat the surfaces well enough,

01:33:56.040 --> 01:34:04.040
or potentially the solder is not good for copper to aluminum.

01:34:04.040 --> 01:34:11.040
So this is like a silver solder, which I think should work, but who knows.

01:34:11.040 --> 01:34:14.040
This is going to be disgustingly hot for a very long time,

01:34:14.040 --> 01:34:18.040
so I'm probably just going to leave it for a while and come back and poke at it later.

01:34:18.040 --> 01:34:23.040
Eventually, at a certain point, once it gets cool enough, I'll just dunk it in a thing of water,

01:34:23.040 --> 01:34:29.040
because once I know all of the solder is solidified and everything,

01:34:29.040 --> 01:34:33.040
honestly, dunking it in water in terms of the copper would actually help it needle it.

01:34:33.040 --> 01:34:37.040
So that would probably not be a bad idea, regardless.

01:34:37.040 --> 01:34:39.040
Then it'll make it a lot softer.

01:34:40.040 --> 01:34:43.040
Ho! Great failure!

01:34:43.040 --> 01:34:46.040
Alright, time for the quench.

01:34:46.040 --> 01:34:50.040
Just for bits and giggles, I'll give you a nice from above view.

01:34:50.040 --> 01:34:54.040
Let's see if this is even attached at all. Yeah, not even a little.

01:34:54.040 --> 01:35:00.040
So this I'll just dunk in, because it's not going to be fun.

01:35:01.040 --> 01:35:03.040
Copper.

01:35:07.040 --> 01:35:10.040
So don't touch any of this crap.

01:35:13.040 --> 01:35:19.040
After doing a bunch of testing on the driving portion of the circuitry,

01:35:19.040 --> 01:35:23.040
I did some tests with our power supply up top,

01:35:23.040 --> 01:35:31.040
and promptly realized it can put out nowhere near enough current to test the power side properly.

01:35:31.040 --> 01:35:40.040
In my next step, I have taken a power cable and given it a snip to supply my input to my rectifier

01:35:40.040 --> 01:35:44.040
and the rest of my power circuitry.

01:35:44.040 --> 01:35:51.040
I have a nice variac right here that allows me to control what level of AC I put into this,

01:35:51.040 --> 01:35:55.040
so I don't just hook this straight up to mains power.

01:35:55.040 --> 01:35:59.040
Though still dangerous, is not quite as bad.

01:35:59.040 --> 01:36:06.040
So I can control how much voltage is coming out of this machine and going into here and loading up this capacitor.

01:36:06.040 --> 01:36:12.040
I have a tiny little discharge resistor as well, and I don't have any load on the output of this.

01:36:12.040 --> 01:36:17.040
So this is just making sure that voltage is actually going in correctly,

01:36:17.040 --> 01:36:20.040
and nothing really bad is going to happen.

01:36:22.040 --> 01:36:25.040
But here we go.

01:36:25.040 --> 01:36:30.040
First things first, some sanity check.

01:36:30.040 --> 01:36:38.040
Measure what the AC voltage out of this bad boy is.

01:36:38.040 --> 01:36:43.040
Zero. Let's go to like 30.

01:36:46.040 --> 01:36:48.040
Let's go to 15.

01:36:49.040 --> 01:36:53.040
Yeah. 15 in change.

01:36:53.040 --> 01:36:57.040
It's reasonable. Power that off.

01:37:01.040 --> 01:37:09.040
This is where the stress comes in, and now I do not get to touch anything moment.

01:37:09.040 --> 01:37:14.040
Because as soon as I turn this on, this capacitor is going to be charged up.

01:37:14.040 --> 01:37:19.040
And that is nothing to mess around with.

01:37:19.040 --> 01:37:21.040
Okay.

01:37:23.040 --> 01:37:31.040
I'm going to prove across the inputs here.

01:37:33.040 --> 01:37:39.040
And these are good for a thousand volts, so I'm not too concerned.

01:37:39.040 --> 01:37:41.040
But here we go.

01:37:44.040 --> 01:37:47.040
It's up to 20 volts.

01:37:47.040 --> 01:37:52.040
That seems about right. Do a quick power off.

01:37:52.040 --> 01:37:58.040
And this is going to take like five minutes to discharge.

01:37:58.040 --> 01:38:03.040
It's a good start.

01:38:03.040 --> 01:38:06.040
A little more sanity check.

01:38:06.040 --> 01:38:11.040
Once this switches on over to the DC side, it's not as concerning.

01:38:11.040 --> 01:38:16.040
Obviously, high DC voltage, still very problematic.

01:38:16.040 --> 01:38:21.040
These two components have a lot of power stored in them.

01:38:21.040 --> 01:38:29.040
And not respecting that they have a lot of power stored in them is going to give you a very bad time.

01:38:29.040 --> 01:38:32.040
And polarity is also correct.

01:38:32.040 --> 01:38:37.040
So that is fantastic news.

01:38:37.040 --> 01:38:42.040
And I just get to wait for that to discharge for a hot minute.

01:38:42.040 --> 01:38:51.040
And next time you see me, I'll have the full circuitry later up in front for a full power test.

01:38:51.040 --> 01:38:57.040
Now on to some moment of truth level shenanigans.

01:38:57.040 --> 01:39:06.040
I have at least the starting version of the quote unquote full power test.

01:39:06.040 --> 01:39:09.040
All of the circuitry is wired up.

01:39:09.040 --> 01:39:16.040
I have the 15 volt supply going to this side.

01:39:16.040 --> 01:39:26.040
But I just noticed that because my nice little heat sink that is keeping my gate drivers alive on this board just shifted at some point.

01:39:26.040 --> 01:39:32.040
Put that back.

01:39:32.040 --> 01:39:39.040
Because I can pretty much guarantee without that they will die.

01:39:39.040 --> 01:39:44.040
Okay.

01:39:44.040 --> 01:39:55.040
My frequency generation into my first stage gate drive into my second stage gate drive into the IGBT block,

01:39:55.040 --> 01:40:08.040
which takes the AC power that comes out of this thing that my brain just refuses to remember the name of the transformer, auto transformer.

01:40:08.040 --> 01:40:16.040
Goes through a three phase full project fire, which I'm all using two phases, which charges these two capacitors,

01:40:16.040 --> 01:40:24.040
which then act as buffers for the IGBTs to pump through this toroid, which may or may not be good enough.

01:40:24.040 --> 01:40:27.040
This may actually be the current bottleneck.

01:40:27.040 --> 01:40:32.040
I then have that toroid coupled to the main loop.

01:40:32.040 --> 01:40:35.040
No idea what the inductance of this thing is.

01:40:35.040 --> 01:40:40.040
And honestly, I don't care as long if I can get anything out of this.

01:40:40.040 --> 01:40:44.040
A plus super win.

01:40:44.040 --> 01:40:51.040
And I will likely put this nice little welded cube I made forever ago when I was learning how to MIG.

01:40:51.040 --> 01:40:55.040
In case you couldn't tell, I was not great.

01:40:55.040 --> 01:41:04.040
Attacked as a heat load at some point. I'm not going to do that right off the bat because I don't want to load up the entire system on the very first attempt.

01:41:04.040 --> 01:41:10.040
That's just begging for problems.

01:41:10.040 --> 01:41:18.040
One thing I'm not totally sure about is the order of operations I really want to take here.

01:41:18.040 --> 01:41:32.040
The thing I can do is just connect these grounds together and then connect these two probes to the ends of this copper pipe.

01:41:32.040 --> 01:41:39.040
I mean, yeah, it's probably fine.

01:41:39.040 --> 01:41:44.040
Keyword, probably fine.

01:41:44.040 --> 01:41:48.040
Okay.

01:41:48.040 --> 01:41:52.040
Oh, is that actually fine?

01:41:52.040 --> 01:41:59.040
I don't know how high the voltage is going to get on this, so I'm actually not going to do that.

01:41:59.040 --> 01:42:13.040
However, what I am going to do is I am going to probe the output of the IGBT to see if it has resolved.

01:42:13.040 --> 01:42:19.040
If making the change I made has resolved the previous issue I had.

01:42:19.040 --> 01:42:24.040
So long as these ground probes don't touch anything, I don't think it matters.

01:42:24.040 --> 01:42:30.040
The only thing I'm actually going to care about is the math difference between them on the oscilloscope.

01:42:30.040 --> 01:42:37.040
So as long as the two grounds are the same, it shouldn't cause any problems.

01:42:37.040 --> 01:42:45.040
So I want this to be 15 volts, peak at two amps, whatever.

01:42:45.040 --> 01:42:54.040
What do I want to turn on first? I will turn this on first.

01:42:54.040 --> 01:42:58.040
And I want this to be in DC.

01:42:58.040 --> 01:43:04.040
Okay, let's do some measurement.

01:43:04.040 --> 01:43:07.040
Okay, let's go at this capacitor.

01:43:07.040 --> 01:43:11.040
Nothing right now. Perfect. Good, good.

01:43:11.040 --> 01:43:18.040
Promptly going up. Now at 20 volts DC, perfect.

01:43:18.040 --> 01:43:21.040
And now let's power this on and see what happens.

01:43:21.040 --> 01:43:30.040
Holy crap, something was vibrating.

01:43:30.040 --> 01:43:43.040
What?

01:43:43.040 --> 01:43:48.040
Okay, okay.

01:43:48.040 --> 01:43:51.040
Is anything getting insanely hot?

01:43:51.040 --> 01:43:56.040
Or did anything get insanely hot? 26 degrees.

01:43:56.040 --> 01:44:03.040
That seems to have gotten warm very quickly.

01:44:03.040 --> 01:44:11.040
Huh. Oh, kiroki.

01:44:11.040 --> 01:44:19.040
So this is going to be a two-handed never now because I need to figure out what is actually going on.

01:44:19.040 --> 01:44:24.040
So I'm going to do a quick power on, stop the probe on the oscilloscope,

01:44:24.040 --> 01:44:28.040
and power it off again because that vibration is very strange.

01:44:28.040 --> 01:44:36.040
And, you know, yeah.

01:44:36.040 --> 01:44:42.040
That has got to be this coil.

01:44:42.040 --> 01:44:45.040
That has got to be this coil.

01:44:45.040 --> 01:44:54.040
What's my... Whoa, whoa, whoa, whoa, whoa, whoa, whoa, whoa, what?

01:44:54.040 --> 01:44:58.040
Ha, ha, ha, ha. Awesome.

01:44:58.040 --> 01:45:01.040
Does that matter?

01:45:01.040 --> 01:45:07.040
No, that's a 60 hertz wave that's not relevant for what I'm doing.

01:45:07.040 --> 01:45:10.040
So...

01:45:10.040 --> 01:45:14.040
And that's getting coupled from a nice ground loop I've created.

01:45:14.040 --> 01:45:18.040
Awesome.

01:45:18.040 --> 01:45:22.040
Okay, well, that's fun.

01:45:22.040 --> 01:45:26.040
So I'm going to show you. Please, God, tell me I turned this on.

01:45:26.040 --> 01:45:34.040
Okay. So this is what happens when you don't ground correctly.

01:45:34.040 --> 01:45:39.040
I'm 95% sure this is a 60 hertz variation.

01:45:39.040 --> 01:45:46.040
And those gigantic spikes are from the variations,

01:45:46.040 --> 01:45:51.040
essentially from the ground loop that I've made with the probe tips.

01:45:51.040 --> 01:45:55.040
So with the probe grounds, so these ones right here.

01:45:55.040 --> 01:45:58.040
And the probes.

01:45:58.040 --> 01:46:08.040
That has made this nice and fairly unreadable plot.

01:46:09.040 --> 01:46:13.040
Mm, noisy.

01:46:13.040 --> 01:46:17.040
Noisy, noisy, noisy. Okay, interesting.

01:46:17.040 --> 01:46:20.040
Made a discovery.

01:46:20.040 --> 01:46:24.040
So I kind of jumped when I turned on the main power,

01:46:24.040 --> 01:46:30.040
sorry, when I turned on the gate driving circuitry

01:46:30.040 --> 01:46:34.040
and had the main power, quote unquote, mains power running,

01:46:34.040 --> 01:46:40.040
the AC power running. What I have just found out is what was actually creating

01:46:40.040 --> 01:46:46.040
that lovely vibration noise is the auto transformer,

01:46:46.040 --> 01:46:52.040
which is great because that means it's not my circuit. So that's awesome.

01:46:52.040 --> 01:46:57.040
One thing I'm not sure about this instance is what is actually working

01:46:57.040 --> 01:47:04.040
and what isn't. I think my next step is going to be probing across the coil here

01:47:04.040 --> 01:47:07.040
with the multimeter.

01:47:07.040 --> 01:47:12.040
That one, not that one, that gives all the pretty plots,

01:47:12.040 --> 01:47:17.040
but this one, because it has a lot higher voltage survivability,

01:47:17.040 --> 01:47:21.040
it can go up to a thousand volts and it will be fine, no problem.

01:47:21.040 --> 01:47:24.040
Whereas that one is a lot more sensitive to higher voltages

01:47:24.040 --> 01:47:28.040
and I do not know what the voltage in this is.

01:47:28.040 --> 01:47:33.040
Because this is a resonance circuit, if I somehow miraculously hit the resonance of it,

01:47:33.040 --> 01:47:38.040
the voltage could get very high and I don't want to blow up any of our measurement devices.

01:47:38.040 --> 01:47:44.040
So I'll be probing with that bad boy.

01:47:44.040 --> 01:47:47.040
That one. And then seeing what happens.

01:47:47.040 --> 01:47:53.040
Okay, so I have all this stuff laid up. I want to do a little bit of fiddling around with the frequency

01:47:53.040 --> 01:47:59.040
just to see how everything, to see if the voltage across these two things increases

01:47:59.040 --> 01:48:02.040
and comes to a peak.

01:48:02.040 --> 01:48:07.040
Yeah. So I'm going to probe across this.

01:48:07.040 --> 01:48:11.040
I also learned that the oscilloscope is just not working.

01:48:11.040 --> 01:48:14.040
For this use case, unfortunately,

01:48:14.040 --> 01:48:17.040
that has mostly to do with the fact

01:48:17.040 --> 01:48:20.040
that I'm getting a ton of common mode noise between the main,

01:48:20.040 --> 01:48:23.040
this power circuit and the oscilloscope,

01:48:23.040 --> 01:48:30.040
because they're running on different circuits and trying to probe this thing is just a nightmare.

01:48:30.040 --> 01:48:34.040
Okay, so this thing is isolated.

01:48:34.040 --> 01:48:37.040
So it measures, it can measure VAC without,

01:48:37.040 --> 01:48:43.040
I think it can measure AC voltage without having a disgusting amount of common mode noise problems

01:48:43.040 --> 01:48:46.040
unlike this oscilloscope, which just does.

01:48:46.040 --> 01:48:49.040
And that's mostly my issue

01:48:49.040 --> 01:48:54.040
and me not grounding correctly or not knowing how to ground correctly.

01:48:54.040 --> 01:48:57.040
But let's try this.

01:49:01.040 --> 01:49:07.040
Okay, so it's 85 millivolts.

01:49:09.040 --> 01:49:12.040
Oh, wow, it peaks at like 160.

01:49:17.040 --> 01:49:21.040
Uh, wait, what? Hey, hold on!

01:49:21.040 --> 01:49:23.040
Hey, hold on!

01:49:26.040 --> 01:49:29.040
There is smoke coming out of the variac.

01:49:31.040 --> 01:49:34.040
That's bad.

01:49:38.040 --> 01:49:41.040
Holy Shiza God,

01:49:41.040 --> 01:49:46.040
that was drawing a lot of current. This cable is like very warm.

01:49:51.040 --> 01:49:56.040
Killing it at 37 degrees, 30, 40 degrees.

01:50:01.040 --> 01:50:03.040
45 degrees.

01:50:05.040 --> 01:50:10.040
40 something degrees. So I think I may have just over-currented this,

01:50:10.040 --> 01:50:13.040
which means that fuse in there is very not good

01:50:13.040 --> 01:50:16.040
and does not work properly.

01:50:16.040 --> 01:50:20.040
Okay, well, that's fun.

01:50:20.040 --> 01:50:24.040
Okay, well, time for more seeing what the F's going on.

01:50:24.040 --> 01:50:29.040
We're going to do some proper vlogging here. So I'm about to take out the fuse,

01:50:29.040 --> 01:50:33.040
which is still extremely intact

01:50:33.040 --> 01:50:38.040
and very much is still functioning as current as intended.

01:50:38.040 --> 01:50:45.040
Clearly, this thing is not,

01:50:45.040 --> 01:50:48.040
it's not spec'd correctly,

01:50:48.040 --> 01:50:51.040
because it was literally smoking.

01:50:51.040 --> 01:50:55.040
I have disconnected it from the wall, disconnected it from the power circuit.

01:50:55.040 --> 01:50:58.040
This thing is just a giant coil,

01:50:58.040 --> 01:51:03.040
so I'm not super concerned about it like,

01:51:03.040 --> 01:51:09.040
like zapping me, but oh boy, is that ever spicy.

01:51:09.040 --> 01:51:12.040
Did not think that was going to happen.

01:51:12.040 --> 01:51:15.040
I expected one of these things to fry,

01:51:15.040 --> 01:51:18.040
not the fricking variac.

01:51:18.040 --> 01:51:21.040
My gosh, it's like pretty warm.

01:51:21.040 --> 01:51:25.040
Interesting. I wonder if the fact that I was drawing at a low power,

01:51:25.040 --> 01:51:29.040
a low voltage meant it was dumping a ton of current.

01:51:29.040 --> 01:51:33.040
I don't actually remember how these things work. I've used them a couple of times,

01:51:33.040 --> 01:51:36.040
but okay, time for some teardown.

01:51:36.040 --> 01:51:39.040
A little bit more vlogging from teardown.

01:51:39.040 --> 01:51:42.040
I took off this front panel.

01:51:42.040 --> 01:51:46.040
Also, if anyone is ever actually deploying one of these things,

01:51:46.040 --> 01:51:49.040
make sure you make some modifications to them

01:51:49.040 --> 01:51:54.040
because the power cable is literally held in with hot glue.

01:51:55.040 --> 01:52:02.040
That plastic sheath does nothing and there's zero strain relief on that power cable at all.

01:52:02.040 --> 01:52:08.040
Also, I'm on the fence about if I think the power,

01:52:08.040 --> 01:52:11.040
the cabling in here is actually rated high enough,

01:52:11.040 --> 01:52:15.040
like thick enough gauge to run 20 amps through them.

01:52:15.040 --> 01:52:18.040
That's very much a big question mark for me right now.

01:52:18.040 --> 01:52:23.040
I'm not sure what was smoking.

01:52:23.040 --> 01:52:26.040
How this actually works is back here,

01:52:26.040 --> 01:52:30.040
you can see that black wire and it's bonded to one of the wires

01:52:30.040 --> 01:52:34.040
around this gigantic toroid in the middle here.

01:52:34.040 --> 01:52:40.040
You can see that it wraps all the way around it and it coils around this entire thing.

01:52:42.040 --> 01:52:49.040
You can see this red wire right here. It connects right there to one of the other coils.

01:52:49.040 --> 01:52:53.040
If I set the wiper, which is that little black thing

01:52:53.040 --> 01:52:57.040
with the gold top, I'm just going to put this down.

01:52:57.040 --> 01:53:01.040
That right there is what actually lets you determine

01:53:01.040 --> 01:53:07.040
what voltage you want to set. It goes around and connects the output,

01:53:07.040 --> 01:53:10.040
which is this yellow wire and goes to these two plugs,

01:53:10.040 --> 01:53:15.040
to whatever the voltage you want is.

01:53:15.040 --> 01:53:18.040
It can actually go above the voltage of the input

01:53:18.040 --> 01:53:21.040
if you move it in this direction,

01:53:21.040 --> 01:53:25.040
this direction relative to where this red wire is connected,

01:53:25.040 --> 01:53:31.040
because that's 120 volts. This particular one I measured and it can go up to 145.

01:53:35.040 --> 01:53:42.040
If you decided to go all the way up here, I was operating way down here, somewhere in that range.

01:53:42.040 --> 01:53:45.040
I don't know what was smoking.

01:53:45.040 --> 01:53:50.040
I have not been able to figure that out. My assumption was that it was either the connection

01:53:50.040 --> 01:53:55.040
between the wiper and the tops of the copper,

01:53:55.040 --> 01:54:00.040
or potentially some of the wiring in here, but I have not been able to identify what it was.

01:54:00.040 --> 01:54:04.040
It could potentially also be the core,

01:54:04.040 --> 01:54:08.040
but I would be very surprised if that was the case.

01:54:08.040 --> 01:54:14.040
My current bet is it's something up top in there.

01:54:14.040 --> 01:54:21.040
Maybe some of the wiring that ties it back to this block here,

01:54:21.040 --> 01:54:24.040
or maybe something just got too hot.

01:54:24.040 --> 01:54:28.040
Yeah, I don't know. I'm not sure if I'm going to use this again,

01:54:28.040 --> 01:54:33.040
but that also means that the next power-on is going to be terrifying.

01:54:33.040 --> 01:54:36.040
The next power-on is going to be at full power,

01:54:36.040 --> 01:54:40.040
well, sorry, full power that I'm going to be using.

01:54:41.040 --> 01:54:45.040
That potentially means that the next time I power this on

01:54:45.040 --> 01:54:49.040
is going to be terrifying because it's going to be at 120 volts,

01:54:49.040 --> 01:54:53.040
which is full power for the sake of this part, at least.

01:54:53.040 --> 01:54:59.040
Eventually, I'll be pumping a lot more power through this, but that's once I'm more comfortable with the circuit and using it.

01:54:59.040 --> 01:55:02.040
Everything seems to be rated for it and should be fine.

01:55:02.040 --> 01:55:05.040
The only thing I'm unsure about is the toroid on the downside,

01:55:05.040 --> 01:55:08.040
on the downstream of the edgy BTs.

01:55:08.040 --> 01:55:13.040
That's something that's a big old question mark because I'm pretty sure the one I have is not going to work properly.

01:55:13.040 --> 01:55:16.040
It's going to get saturated like nobody's freaking business,

01:55:16.040 --> 01:55:24.040
and I'm going to have to source another one, which would suck. But maybe I'll just take this apart and use that gigantic toroid.

01:55:24.040 --> 01:55:30.040
Who knows? Though this thing probably isn't designed for the frequencies I would use it for.

01:55:30.040 --> 01:55:34.040
We'll see. I'll have to do some digging if that doesn't pan out,

01:55:34.040 --> 01:55:38.040
but I think that's probably pretty much it for today.

01:55:38.040 --> 01:55:42.040
I've hit a point of a little bit of full YOLO.

01:55:42.040 --> 01:55:51.040
I am going to try plugging the power side just straight into the wall.

01:55:51.040 --> 01:55:56.040
Everything here is rated for that voltage or way higher.

01:55:56.040 --> 01:56:02.040
This capacitor is rated for up to 1500 volts.

01:56:02.040 --> 01:56:05.040
This capacitor is rated up to 700 volts.

01:56:05.040 --> 01:56:08.040
The two IGBTs are rated to 600 volts,

01:56:08.040 --> 01:56:19.040
and this three phase Fulbridge rectifier is rated up to, I believe, 240 volts.

01:56:19.040 --> 01:56:23.040
So I'm just going to send it.

01:56:23.040 --> 01:56:29.040
But you're going to see it because if something decides to go kaputz,

01:56:29.040 --> 01:56:32.040
it's probably going to be pretty spectacular.

01:56:32.040 --> 01:56:37.040
And I'm actually going to move a little out of the way just in case.

01:56:37.040 --> 01:56:40.040
So if it pops, it'll pop quick.

01:56:40.040 --> 01:56:46.040
Okay, here we go.

01:56:46.040 --> 01:56:49.040
No smoke.

01:56:49.040 --> 01:56:57.040
No craziness. This is definitely at the point where I do not want to get anywhere near touching any of this.

01:56:57.040 --> 01:57:04.040
This is now properly dangerous.

01:57:04.040 --> 01:57:08.040
So this is a hundred and seventy volts DC.

01:57:08.040 --> 01:57:15.040
And then the input is going to be something around 120-ish.

01:57:15.040 --> 01:57:18.040
Heavy on the ish.

01:57:18.040 --> 01:57:25.040
So I'm going to try turning on the power.

01:57:26.040 --> 01:57:34.040
One second, please.

01:57:34.040 --> 01:57:38.040
Well, that was fun.

01:57:38.040 --> 01:57:47.040
So what happened? I took all of this beefcake circuitry, all of these caps, all this everything.

01:57:47.040 --> 01:57:50.040
It charged up when I plugged it in. No problem.

01:57:50.040 --> 01:57:54.040
Actually, it's plugged in again. I should very much turn that off.

01:57:54.040 --> 01:58:07.040
What happened next was I turned on the gate control circuitry and I blew the breaker.

01:58:07.040 --> 01:58:17.040
So that tells me I either have a dead short somewhere or this draws so much power.

01:58:17.040 --> 01:58:21.040
And I probably need to load that heavier.

01:58:21.040 --> 01:58:25.040
That that's just really bad.

01:58:25.040 --> 01:58:29.040
Yeah, okay. Well, that's a fun learning experience.

01:58:29.040 --> 01:58:34.040
I'm going to unplug that and make sure it's safe and then call it a day.

01:58:34.040 --> 01:58:40.040
I just had a gargantuan RTFM moment.

01:58:40.040 --> 01:58:48.040
So I was trying to troubleshoot why the heck I was maxing out power supplies, blowing breakers,

01:58:48.040 --> 01:58:58.040
drawing just ridiculous amounts of current and seemingly getting literally nothing through the out of the IGBT block.

01:58:58.040 --> 01:59:04.040
So I started poking around at it a little bit more and I realized I made a very poor assumption

01:59:04.040 --> 01:59:08.040
and I was entirely incorrect with this assumption.

01:59:08.040 --> 01:59:20.040
And the repercussions of that were that I was shorting directly through from the high side voltage straight to the return line.

01:59:20.040 --> 01:59:24.040
Not going through the output at all or well, the output was still there,

01:59:24.040 --> 01:59:32.040
but the resistance through the IGBT was so tiny that it was just bolting through that instead.

01:59:32.040 --> 01:59:35.040
My realization came.

01:59:35.040 --> 01:59:38.040
So in my circuitry and all my circuit diagrams,

01:59:38.040 --> 01:59:47.040
I need to connect the gate reversed on one side to make sure that I don't have both of them on at the same time.

01:59:47.040 --> 01:59:52.040
So I was looking at the pictures on the IGBTs and I saw, okay, cool, cool, cool.

01:59:52.040 --> 01:59:55.040
So this is my collector one.

01:59:55.040 --> 01:59:59.040
This is my emitter to this is my collector to an emitter one,

01:59:59.040 --> 02:00:02.040
which essentially means this is the output in the middle.

02:00:02.040 --> 02:00:05.040
This is the bottom and this is the top.

02:00:05.040 --> 02:00:13.040
And I incorrectly assumed that each of these pins were what I thought they were.

02:00:13.040 --> 02:00:26.040
Whereas in this was this pin was the emitter collector pin and this was the gate and this was the emitter pin and this was the gate.

02:00:26.040 --> 02:00:30.040
My incorrect assumption. This is the gate.

02:00:30.040 --> 02:00:38.040
This is the emitter. So while my circuit was turning on, whenever my gate driving circuit was turning on,

02:00:38.040 --> 02:00:46.040
I was literally shorting the pins with power in and power out.

02:00:46.040 --> 02:00:50.040
So that's a fun learning experience.

02:00:50.040 --> 02:00:55.040
On the bright side, that means I can probably get this working today.

02:00:56.040 --> 02:01:00.040
Good Lord. And we're back at it.

02:01:00.040 --> 02:01:05.040
Everyone who's Uber turbo keen, although you probably can't see it from any of the angles I actually showed you,

02:01:05.040 --> 02:01:12.040
all of these twists have heat shrink on them to indicate which side is which and also their different sized ferrules that I used.

02:01:12.040 --> 02:01:18.040
I have switched these so they are hopefully correctly oriented this time.

02:01:18.040 --> 02:01:23.040
I rebuild old circuit. I'm not going to power this off the wall this time.

02:01:23.040 --> 02:01:30.040
For now, I'm going to start by using the bench power supply.

02:01:30.040 --> 02:01:33.040
Powering this up with DC.

02:01:33.040 --> 02:01:36.040
Essentially, none of this is actually connected.

02:01:36.040 --> 02:01:40.040
It's not being used. It's connected, but it's not being used.

02:01:40.040 --> 02:01:47.040
So I'll run this. I have a nice little IR thermometer just for shits and giggles to see if this thing gets hot.

02:01:47.040 --> 02:01:52.040
And if it does, oh boy, are we getting somewhere.

02:01:52.040 --> 02:01:57.040
But here we go. So power on running effectively no power.

02:01:57.040 --> 02:02:01.040
So I have this energized at five volts.

02:02:01.040 --> 02:02:05.040
So I'm not concerned about being near it. It's less.

02:02:05.040 --> 02:02:15.040
It's less voltage than touching a nine volt. There's a lot more power here, but it's not going to get through my skin and power.

02:02:15.040 --> 02:02:18.040
Okay. That's a lot better.

02:02:18.040 --> 02:02:33.040
That's a ton better. So I turned on the driving circuitry and this only drew only only drew half an amp instead of 10.

02:02:33.040 --> 02:02:39.040
Fantastic. That's amazing news for me.

02:02:39.040 --> 02:02:42.040
That's not hot. That's not hot.

02:02:42.040 --> 02:02:45.040
That's fine. That's fine. That's fine.

02:02:45.040 --> 02:02:52.040
That's fine. Okay. Time to photograph some probes, I think.

02:02:52.040 --> 02:02:57.040
I still have to figure out how the F I want to do this.

02:02:57.040 --> 02:03:02.040
Do, do, do, do, do.

02:03:02.040 --> 02:03:07.040
Let's grab these two just to start.

02:03:07.040 --> 02:03:12.040
I want to connect the grounds together.

02:03:12.040 --> 02:03:16.040
That shouldn't allow for any common noise, but obviously it totally will because I'm just being

02:03:16.040 --> 02:03:24.040
dumb. Let's measure across the capacitor.

02:03:24.040 --> 02:03:32.040
So what I definitely want to not want to not have happened is have these two ground connections.

02:03:32.040 --> 02:03:36.040
Connections should connect to this because that would just be really bad.

02:03:36.040 --> 02:03:41.040
Technically it should be isolated so it shouldn't cause any problems, but oh, do we ever know

02:03:41.040 --> 02:03:45.040
that's not something I want to rely on in this circuit.

02:03:45.040 --> 02:03:48.040
That would be terrifying. Okay. Here we go.

02:03:48.040 --> 02:04:11.040
That's fun. Okay. I'm getting a little bit of movement, but really not very much.

02:04:11.040 --> 02:04:21.040
Hang on.

02:04:21.040 --> 02:04:27.040
Something I just thought about. I'm measuring the voltage across here.

02:04:27.040 --> 02:04:32.040
The resistance in this circuit is very small.

02:04:32.040 --> 02:04:37.040
Like very small, although the impedance is reasonable, but let's see.

02:04:37.040 --> 02:04:47.040
What are we looking at here for the voltage?

02:04:47.040 --> 02:04:52.040
We're looking at plus or minus a volt, roughly.

02:04:52.040 --> 02:04:55.040
Yeah. Plus or minus about two volts.

02:04:55.040 --> 02:05:00.040
Yeah. Okay. Which, given the input is five.

02:05:00.040 --> 02:05:06.040
Sorry. Plus or minus one volt, total variation one volt, two volts.

02:05:06.040 --> 02:05:11.040
That's not bad considering I've done literally zero tuning.

02:05:11.040 --> 02:05:18.040
So let's turn that on again. Turn this on again and adjust the trigger.

02:05:18.040 --> 02:05:23.040
How much power am I drawing?

02:05:23.040 --> 02:05:26.040
That's probably fine. Where's my trigger?

02:05:26.040 --> 02:05:29.040
What am I triggering on?

02:05:30.040 --> 02:05:34.040
Oh, a channel that's not enabled. That's super smart.

02:05:34.040 --> 02:05:38.040
Thanks, Keysight.

02:05:38.040 --> 02:05:41.040
Why are you not triggering?

02:05:41.040 --> 02:05:47.040
Hello. Thank you.

02:05:47.040 --> 02:05:50.040
That looks much better. Okay.

02:05:50.040 --> 02:05:58.040
Let's do some tuning. That did not change a damn thing, probably because my trigger is not working.

02:05:58.040 --> 02:06:22.040
So it seems like this particular setup is resonating right around the top end of my potentiometers

02:06:22.040 --> 02:06:33.040
range. And that is giving me almost a completely pure sine wave here, which is great.

02:06:33.040 --> 02:06:36.040
That's what I want.

02:06:36.040 --> 02:06:42.040
And the total voltage change is looking like one, like 1.6 volts.

02:06:42.040 --> 02:06:47.040
It's really not very big.

02:06:47.040 --> 02:06:50.040
Yeah. So it's like 1.6 volts.

02:06:50.040 --> 02:06:53.040
Is it getting warm?

02:06:53.040 --> 02:06:58.040
27. It's hot AF in here, by the way.

02:06:58.040 --> 02:07:02.040
Is it getting warm? No.

02:07:02.040 --> 02:07:06.040
28 degrees. 28 degrees.

02:07:06.040 --> 02:07:09.040
Oh, that's thirsty.

02:07:09.040 --> 02:07:12.040
52.

02:07:12.040 --> 02:07:16.040
That's a little uncomfortable with the warm.

02:07:16.040 --> 02:07:20.040
So that's going to need active cooling. Sure.

02:07:20.040 --> 02:07:26.040
For sure.

02:07:26.040 --> 02:07:30.040
I could probably run this off the wall now.

02:07:30.040 --> 02:07:33.040
I'm not going to yet.

02:07:33.040 --> 02:07:37.040
I want to get active cooling for this first.

02:07:37.040 --> 02:07:42.040
I'll bump it up to 6 volts just because I can.

02:07:42.040 --> 02:07:45.040
Run this.

02:07:45.040 --> 02:07:48.040
Okay. Stop that.

02:07:48.040 --> 02:07:54.040
1.25 amps. Damn, that's toasty.

02:07:54.040 --> 02:08:00.040
Whoo. 52 degrees, bud.

02:08:00.040 --> 02:08:04.040
That's hot. How about this?

02:08:04.040 --> 02:08:08.040
Oh, yeah, I should not touch that cap. Actually, it's 6 volts is fine.

02:08:08.040 --> 02:08:12.040
These things are fine. They're barely warm.

02:08:12.040 --> 02:08:16.040
They're barely warmer than this room.

02:08:16.040 --> 02:08:20.040
Which isn't saying much because the room's hot as heck.

02:08:20.040 --> 02:08:24.040
Let's just turn that on. Okay.

02:08:24.040 --> 02:08:26.040
Um...

02:08:29.040 --> 02:08:38.040
So I'm getting plus or minus some volts. Whistling.

02:08:38.040 --> 02:08:41.040
Oh.

02:08:41.040 --> 02:08:45.040
Head full cap to the bottom. Head to the bottom.

02:08:45.040 --> 02:08:47.040
Head to the bottom.

02:08:49.040 --> 02:08:54.040
I'm starting to wrap up the coils or the singular coil at this point

02:08:54.040 --> 02:09:00.040
for the actual work side of the...

02:09:00.040 --> 02:09:06.040
I'm wrapping up the coil for the work...

02:09:06.040 --> 02:09:12.040
I started wrapping up the work coil and I was using this nice little like

02:09:12.040 --> 02:09:16.040
push-in adapter for PVC pipes to a corrugated pipe.

02:09:16.040 --> 02:09:19.040
And then I was...

02:09:19.040 --> 02:09:23.040
It's kind of a pain in the butt because of all of these lips getting the coil wrapped around it

02:09:23.040 --> 02:09:27.040
and then getting it off. It's kind of a pain in the ass.

02:09:27.040 --> 02:09:31.040
And I promptly realized our nice water bottles from lttstore.com, this is an old one,

02:09:31.040 --> 02:09:34.040
but are about 3.5 inches in diameter,

02:09:34.040 --> 02:09:40.040
which is pretty much exactly what I'm looking for. So I can just wrap it around that instead.

02:09:40.040 --> 02:09:44.040
Yay! That's very convenient for me because this is straight

02:09:44.040 --> 02:09:48.040
and I can get the tube off no problem unlike the corrugated connector

02:09:48.040 --> 02:09:52.040
which is a gigantic pain in the butt. That was a fun little workout.

02:09:52.040 --> 02:09:58.040
This tube is... This coil is a little...

02:09:58.040 --> 02:10:01.040
Actually better than I thought it was going to turn out.

02:10:01.040 --> 02:10:05.040
We're going to have to compress it down a little bit and make sure that all of these individual pipes

02:10:05.040 --> 02:10:09.040
are isolated. So when I put barbed steel

02:10:09.040 --> 02:10:14.040
or whatever else I put in here, it doesn't short between each of the coils,

02:10:14.040 --> 02:10:18.040
which wouldn't be that... It would not be good.

02:10:18.040 --> 02:10:23.040
It wouldn't be that bad because copper is super conductive so it's not going to make anything like really, really bad,

02:10:23.040 --> 02:10:26.040
but ideally I would not have any of this

02:10:26.040 --> 02:10:29.040
able to be electrically contacted with something.

02:10:29.040 --> 02:10:33.040
Obviously you can touch it, which is still not great.

02:10:33.040 --> 02:10:36.040
It shouldn't be that hot because of the water running through it,

02:10:36.040 --> 02:10:39.040
but yeah, this is definitely not something

02:10:39.040 --> 02:10:44.040
to accidentally hit because there's going to be a lot of voltage

02:10:44.040 --> 02:10:48.040
and power in it. Though it should be isolated from everything,

02:10:48.040 --> 02:10:53.040
so it shouldn't be that bad. It's still not something that you would want to touch.

02:10:53.040 --> 02:10:58.040
Certainly not unintentionally. But yeah, that wasn't actually too bad.

02:10:58.040 --> 02:11:03.040
I have starting here three, four, five, six and a half

02:11:03.040 --> 02:11:06.040
turns I need seven and a half.

02:11:06.040 --> 02:11:12.040
Okay. I can do basic math sometimes.

02:11:20.040 --> 02:11:25.040
There we go. Seven and a half turns.

02:11:25.040 --> 02:11:28.040
So that gives me what I'm looking for.

02:11:28.040 --> 02:11:33.040
And then according to my math, I'm looking for a total length of this coil

02:11:33.040 --> 02:11:36.040
of about six inches.

02:11:36.040 --> 02:11:43.040
I'm pretty sure this is a little bigger, but it'll be a good place to start.

02:11:43.040 --> 02:11:48.040
Oh no, actually, this is like bang on six and a half inches, so I'll take it down a little bit probably

02:11:48.040 --> 02:11:53.040
because if I really check some math,

02:11:53.040 --> 02:11:59.040
that would make it, and it's probably fine.

02:11:59.040 --> 02:12:02.040
It probably doesn't matter.

02:12:02.040 --> 02:12:05.040
Next up, chopping some stuff,

02:12:05.040 --> 02:12:08.040
figuring out how to connect this

02:12:08.040 --> 02:12:13.040
to the actual capacitor

02:12:13.040 --> 02:12:20.040
with the help of a couple of these. And then I need to get the coupling toroid

02:12:20.040 --> 02:12:24.040
around the capacitor side of these,

02:12:24.040 --> 02:12:28.040
so that these are small enough that I can just take it off if I need to.

02:12:28.040 --> 02:12:33.040
So that's very nice. I'm going to leave this one side a little longer

02:12:33.040 --> 02:12:36.040
just to allow myself, if I need to,

02:12:36.040 --> 02:12:42.040
to bend in to connect to the other compression fitting

02:12:42.040 --> 02:12:46.040
because I'm pretty sure those are only three and a half inches apart.

02:12:46.040 --> 02:12:49.040
So I have that option.

02:12:49.040 --> 02:12:52.040
Nice, and then that will fit on something

02:12:52.040 --> 02:12:57.040
like a little pressed slash mangled,

02:12:57.040 --> 02:13:01.040
but that'll fit something like that. It will compress down,

02:13:01.040 --> 02:13:05.040
but I'll show you a little more detail on how that actually works. Want to do it?

02:13:05.040 --> 02:13:08.040
Yay, getting there. In front of me sits a lot of things

02:13:08.040 --> 02:13:13.040
that I'm going to have to put together before I am done here.

02:13:13.040 --> 02:13:16.040
Extra tubing, extra tubing for who the heck knows what reason.

02:13:16.040 --> 02:13:20.040
I'll probably end up making a smaller diameter

02:13:20.040 --> 02:13:26.040
work coil eventually, but that's going to be a later endeavor for sure.

02:13:26.040 --> 02:13:31.040
So that can just chill. So I have a nice deburring tool.

02:13:31.040 --> 02:13:35.040
I have a pipe cutter, and then I have some swage lock fittings.

02:13:35.040 --> 02:13:39.040
These are brass and designed for relatively soft materials,

02:13:39.040 --> 02:13:42.040
or at least these swages are designed

02:13:42.040 --> 02:13:48.040
for relatively soft materials. These ones in particular for copper.

02:13:48.040 --> 02:13:54.040
How it actually works is you put the nut over your pipe,

02:13:54.040 --> 02:13:57.040
you put the two swages over top as well,

02:13:57.040 --> 02:14:03.040
and then the inside of these connections has a taper on it that kind of lines up with this.

02:14:03.040 --> 02:14:09.040
What happens is that taper compresses against here,

02:14:09.040 --> 02:14:12.040
and then the nut tightens these together

02:14:12.040 --> 02:14:18.040
and squishes this inner intersection into here,

02:14:18.040 --> 02:14:21.040
compressing it, holding the copper pipe,

02:14:21.040 --> 02:14:25.040
and it actually compresses the copper pipe as well. So this is a permanent fixture,

02:14:25.040 --> 02:14:28.040
which also means you can't get this nut off ever

02:14:28.040 --> 02:14:32.040
without cutting it or somehow pulling the swage off.

02:14:32.040 --> 02:14:37.040
That's why I have a couple of extra nuts kicking around, as well as a couple of extra swage sets,

02:14:37.040 --> 02:14:40.040
so I can have multiple work coils

02:14:40.040 --> 02:14:44.040
if I need them for different use cases.

02:14:44.040 --> 02:14:49.040
But before I do that, after you use this pipe cutter,

02:14:49.040 --> 02:14:53.040
the inside of the pipe is really sharp and jagged,

02:14:53.040 --> 02:14:56.040
and in some situations the outside even has a lip on it

02:14:56.040 --> 02:15:01.040
that you need to take down. So I have this deburring tool that I'll use

02:15:01.040 --> 02:15:04.040
to clean up the insides of these.

02:15:04.040 --> 02:15:08.040
Unfortunately, which I may end up regretting later,

02:15:08.040 --> 02:15:13.040
I may have actually sandblasted the copper pipe here.

02:15:13.040 --> 02:15:16.040
So I sandblasted the copper pipe here

02:15:16.040 --> 02:15:19.040
when I was cleaning up after brazing,

02:15:19.040 --> 02:15:22.040
and that's going to suck,

02:15:22.040 --> 02:15:26.040
because that might mean that these swage fittings won't work.

02:15:26.040 --> 02:15:31.040
I will have to test that and hope.

02:15:31.040 --> 02:15:34.040
But I'll end up probably trimming both of these down

02:15:34.040 --> 02:15:40.040
to be in line with each other, swaging the fittings on here.

02:15:40.040 --> 02:15:47.040
Maybe I'll leave it a little bit longer, actually, because I need to have the matching coil on it.

02:15:47.040 --> 02:15:52.040
So I'll leave it a little bit longer, probably cut it somewhere around here or something like that,

02:15:52.040 --> 02:15:56.040
just to get rid of this really bad section, or maybe I'll use this side.

02:15:56.040 --> 02:16:00.040
I haven't figured that out yet. We'll cross that bridge when we get there.

02:16:00.040 --> 02:16:06.040
I'll cut it off, trim the insides, and then do the swage fittings.

02:16:06.040 --> 02:16:10.040
But yeah, up until that point, this is going to be very interesting,

02:16:10.040 --> 02:16:15.040
because it's just going to be a lot of cutting copper pipe. Back out in the shop where we have all of the tools,

02:16:15.040 --> 02:16:19.040
instead of just a couple of the tools, I can create a warehouse for the time being.

02:16:19.040 --> 02:16:23.040
So I've recollected everything I needed, including a couple of wrenches.

02:16:23.040 --> 02:16:28.040
These particular swage lock fittings use half-inch for this smaller central piece.

02:16:28.040 --> 02:16:31.040
And then what is it, 9-16ths?

02:16:31.040 --> 02:16:35.040
9-16ths for the bigger side. So grab both of those because you need both.

02:16:35.040 --> 02:16:40.040
And now I get to just do a little bit of copper pipe treatments.

02:16:40.040 --> 02:16:44.040
So earlier on, I had used a slightly smaller,

02:16:44.040 --> 02:16:48.040
well, slightly, a non-trivial smaller pipe cutter.

02:16:48.040 --> 02:16:52.040
I ended up switching to this bigger one because it's newer.

02:16:52.040 --> 02:16:57.040
It has a fresher blade. I know you can just replace the blades from them.

02:16:57.040 --> 02:17:01.040
But, you know, I'm here on the weekend. And no one's here, no one's here.

02:17:01.040 --> 02:17:06.040
Because I like random projects that scope is way too big.

02:17:06.040 --> 02:17:10.040
But it's fun. I like pushing myself to learn.

02:17:10.040 --> 02:17:15.040
And also applying skills I've learned in different ways,

02:17:15.040 --> 02:17:18.040
which is just fun too.

02:17:18.040 --> 02:17:23.040
One other thing I learned. So when I braised these two pieces,

02:17:23.040 --> 02:17:26.040
I thought I was very smart in my orientation.

02:17:26.040 --> 02:17:31.040
I put them both flat down and braised it, soldered, whatever.

02:17:31.040 --> 02:17:34.040
So the long pipes were on the same sides.

02:17:34.040 --> 02:17:37.040
Being a little bit of a dingus,

02:17:37.040 --> 02:17:40.040
forgetting of the fact that in order to connect them to the capacitor,

02:17:40.040 --> 02:17:43.040
you have to flip them around so the two different lengths are different.

02:17:43.040 --> 02:17:46.040
The two longer sides are on opposite ends.

02:17:46.040 --> 02:17:50.040
Conveniently, I can flip one of them over

02:17:50.040 --> 02:17:53.040
and just go to this other hole that already existed.

02:17:53.040 --> 02:18:01.040
And that more or less makes it line up. So I can actually have the long sides that I didn't sandblast together.

02:18:01.040 --> 02:18:06.040
Ah, details. I still have to shorten up one of these sides, unfortunately.

02:18:06.040 --> 02:18:13.040
Wow, okay, half two is a strong word. I probably actually won't because I think this is an end of the copper roll.

02:18:13.040 --> 02:18:16.040
I don't really want to cut it down and then retreat the outsides

02:18:16.040 --> 02:18:21.040
just because it's a pain in the butt. So I may actually just leave it

02:18:21.040 --> 02:18:26.040
and have one of the copper shifted like this.

02:18:26.040 --> 02:18:29.040
Ah, sorry, no.

02:18:29.040 --> 02:18:34.040
Like that. Haha, yes, like that.

02:18:34.040 --> 02:18:37.040
The holes are almost lined up, but not quite.

02:18:37.040 --> 02:18:41.040
So there'll be a little bit of an offset, but this has an offset, so whatever.

02:18:41.040 --> 02:18:48.040
That's fine. So next step, do some swaging.

02:18:48.040 --> 02:18:55.040
Alright, so as I had mentioned prior, you have four parts, four pieces,

02:18:55.040 --> 02:18:58.040
not including the tube. Hold on.

02:18:58.040 --> 02:19:04.040
They make this happen. For this type, there are other types where it's just one inner piece,

02:19:04.040 --> 02:19:09.040
but these are the ones that I have. So you have the two inner pieces that go in.

02:19:09.040 --> 02:19:14.040
You have your nut and you have the connection, or in this case, the union.

02:19:14.040 --> 02:19:18.040
So I'll more or less tighten it down, hand tight.

02:19:18.040 --> 02:19:24.040
So put it on. Step one. Step two, hand tighten it until it's like reasonably tight.

02:19:24.040 --> 02:19:28.040
There's still some a little bit of movement in the fitting.

02:19:28.040 --> 02:19:33.040
So normally Swagelock has standardized fitting procedures for these things

02:19:33.040 --> 02:19:38.040
to allow you to continually reuse them with only slight tightening,

02:19:38.040 --> 02:19:44.040
slight additional tightening steps. So for these, I'm going to go a little bit overboard with how much I'm tightening it down.

02:19:44.040 --> 02:19:50.040
Not for this particular one, just because I'm going to be taking it apart to show you what happens

02:19:50.040 --> 02:19:56.040
when I do it, but if I recall correctly, you're supposed to mark where it lines up

02:19:56.040 --> 02:20:02.040
and then you tighten it down a particular amount for each tightening

02:20:02.040 --> 02:20:06.040
and each removal and reattachment of the joint.

02:20:10.040 --> 02:20:17.040
I'll go start with half just because that should be more than enough to make this wage engage.

02:20:17.040 --> 02:20:22.040
So now undo it and if things have gone well,

02:20:22.040 --> 02:20:29.040
well, they didn't go well. So that's fun.

02:20:29.040 --> 02:20:33.040
Okay. Well, that didn't behave as I wanted it to.

02:20:33.040 --> 02:20:37.040
Okay.

02:20:37.040 --> 02:20:43.040
Time to try again. This copper pipe might actually be a little thin for this,

02:20:43.040 --> 02:20:46.040
but at the moment, I don't have another option.

02:20:46.040 --> 02:20:49.040
So it's going to be what I'm doing.

02:20:49.040 --> 02:20:52.040
Let's skip it.

02:20:52.040 --> 02:20:55.040
Three quarters of a turn roughly.

02:20:55.040 --> 02:20:59.040
Okay. Now I'll loosen it off.

02:20:59.040 --> 02:21:03.040
Okay. So yeah, that was really easy comparatively.

02:21:03.040 --> 02:21:07.040
That should mean.

02:21:07.040 --> 02:21:13.040
Okay. It's still pretty loose, but now this is attached to this part.

02:21:13.040 --> 02:21:18.040
This copper pipe is definitely a little bit thin for this particular process.

02:21:18.040 --> 02:21:22.040
But oh well, such as life. You can see that it's actually bulging here.

02:21:22.040 --> 02:21:26.040
That's not great.

02:21:26.040 --> 02:21:29.040
That probably just means I put the pipe too far back, whatever.

02:21:29.040 --> 02:21:32.040
That's not the end of the world.

02:21:32.040 --> 02:21:36.040
So let's clamp this down again.

02:21:36.040 --> 02:21:40.040
And in general, every time you reattach, you have to tighten it more

02:21:40.040 --> 02:21:46.040
to make sure you actually get a good seal. Eventually I will actually pressure test this.

02:21:46.040 --> 02:21:51.040
Pretty sure these copper fittings aren't going to be where things leak.

02:21:51.040 --> 02:21:54.040
Also, if I was actually doing this properly and it mattered,

02:21:54.040 --> 02:21:57.040
it doesn't matter here. There's a little bit of water leakage.

02:21:57.040 --> 02:22:04.040
I can just tighten it down more later. I'd be properly following the guidelines, treating all of the pipes correctly,

02:22:04.040 --> 02:22:08.040
blah, blah, blah, blah, blah, blah. But for this, it doesn't matter.

02:22:08.040 --> 02:22:12.040
All right, next one.

02:22:12.040 --> 02:22:29.040
Same steps. Put it on.

02:22:29.040 --> 02:22:34.040
Tighten her down.

02:22:34.040 --> 02:22:43.040
Okay, here I'll go again a little more than three quarters of a turn.

02:22:43.040 --> 02:22:46.040
That's not going anywhere.

02:22:46.040 --> 02:22:51.040
Primo. So now I have my two fittings that are connected and not even remotely straight,

02:22:51.040 --> 02:22:56.040
but it doesn't matter because it's not connecting to anything even remotely straight.

02:22:56.040 --> 02:23:01.040
I get to reconnect all of these two plates to the cap.

02:23:01.040 --> 02:23:05.040
And of course, that's coming in.

02:23:05.040 --> 02:23:11.040
All right, so this one goes this direction.

02:23:11.040 --> 02:23:15.040
It's going to go hand tight for right now, and then I'll roughly line them up.

02:23:15.040 --> 02:23:22.040
And this one has to go the opposite direction because, ha, details.

02:23:22.040 --> 02:23:35.040
I will, after having to change my pants, take these two plates down to the same size,

02:23:35.040 --> 02:23:38.040
eventually, just for ease of use.

02:23:38.040 --> 02:23:43.040
I'm going to rest these on top of some plastic just to give isolation for the time being,

02:23:43.040 --> 02:23:51.040
but eventually I want these two copper plates to be appropriately dimensioned.

02:23:51.040 --> 02:23:55.040
Okay, tighten that bad boy down.

02:23:55.040 --> 02:23:59.040
Get that roughly aligned.

02:23:59.040 --> 02:24:03.040
Very much on the roughly...

02:24:03.040 --> 02:24:06.040
Okay, cool.

02:24:06.040 --> 02:24:12.040
So now it's going to sit super wank, super jank, super wankily-dankily.

02:24:12.040 --> 02:24:16.040
Wow, okay, let's not include that.

02:24:16.040 --> 02:24:20.040
Winga, winga, winga, winga, tell us the weekend.

02:24:20.040 --> 02:24:26.040
Okay, my next problem. I have my two connections right here.

02:24:26.040 --> 02:24:30.040
Then I have the two sides of the coil.

02:24:30.040 --> 02:24:36.040
Hey, big shocker, they don't line up even remotely.

02:24:36.040 --> 02:24:40.040
There are a couple of different ways to resolve this problem.

02:24:40.040 --> 02:24:47.040
But realistically, how I'm going to solve this problem is with some jank pipe bending

02:24:48.040 --> 02:24:51.040
lots of hope that I don't break the coil

02:24:51.040 --> 02:24:56.040
because I don't really have enough free material to make another one.

02:24:56.040 --> 02:24:59.040
Yay! So I'm going to make a couple of modifications.

02:24:59.040 --> 02:25:02.040
One of them is I want to bend this pipe in a little,

02:25:02.040 --> 02:25:08.040
and this one's going to have to probably come in and then straighten out over here or something like that.

02:25:08.040 --> 02:25:12.040
I haven't exactly ironed out what this is going to be, and it's honestly going to be a lot of like,

02:25:12.040 --> 02:25:19.040
hey, rule of thumbing it to ... eyeballing the crap out of it to see how it works.

02:25:19.040 --> 02:25:23.040
Thankfully working with soft, annealed copper tubing, very easy.

02:25:23.040 --> 02:25:30.040
I can just do it by hand. I just have to avoid crushing it because that's a thing you can do with copper tubing,

02:25:30.040 --> 02:25:34.040
is hulk too much and just crush it.

02:25:34.040 --> 02:25:38.040
Ha, whoops, ask me how I know. I've already done it once.

02:25:39.040 --> 02:25:40.040
Whoops!

02:25:42.040 --> 02:25:44.040
This is really annoying.

02:25:48.040 --> 02:25:51.040
Okay, so realistically this is going to have to bend down,

02:25:51.040 --> 02:25:54.040
come into here, and then straighten out and go in.

02:25:54.040 --> 02:25:57.040
This might actually even be too long.

02:25:58.040 --> 02:26:01.040
But, I'll grab the bender.

02:26:01.040 --> 02:26:12.040
I'm going to try using this bender once.

02:26:12.040 --> 02:26:15.040
Chances are I'm not going to use it after that.

02:26:15.040 --> 02:26:26.040
I recall watching a Linus and I think a Jake struggle epically with this thing when they were using it.

02:26:26.040 --> 02:26:30.040
For some, if I think it was for a hardline copper tubing video.

02:26:30.040 --> 02:26:35.040
Which, haha, copper tubing, hardlining.

02:26:35.040 --> 02:26:39.040
That's totally not something Linus is going to hate me for later.

02:26:40.040 --> 02:26:44.040
Boilers, if you didn't actually watch my actual upgrade.

02:26:44.040 --> 02:26:49.040
Yeah, that was probably a mistake.

02:26:49.040 --> 02:26:53.040
I don't actually know how it went yet, because it hasn't happened.

02:26:53.040 --> 02:26:56.040
I'm pretty sure the answer is not well.

02:26:56.040 --> 02:27:01.040
Wow, this is really, really, really, really, really awkward to use.

02:27:01.040 --> 02:27:02.040
Holy moly.

02:27:05.040 --> 02:27:10.040
Okay, that's cool, I guess.

02:27:10.040 --> 02:27:23.040
Okay, sure.

02:27:23.040 --> 02:27:28.040
That didn't do even remotely what I wanted.

02:27:28.040 --> 02:27:35.040
Because I want this to sit horizontal, I think.

02:27:36.040 --> 02:27:39.040
I need to bend this up.

02:27:39.040 --> 02:27:44.040
Oh god, that was literally the wrong, completely wrong bend.

02:27:44.040 --> 02:27:47.040
That's unfortunate, thankfully.

02:27:47.040 --> 02:27:53.040
Soft and yield copper. Yeah buddy, not straight, but it doesn't matter.

02:27:53.040 --> 02:27:58.040
So let's just do one of these then.

02:27:58.040 --> 02:28:02.040
I should have...

02:28:02.040 --> 02:28:08.040
Dang it, I don't have my LTT water bottle that I used as a form.

02:28:08.040 --> 02:28:14.040
Because I could, and it worked actually really, really, really, really well.

02:28:17.040 --> 02:28:20.040
Okay, so that's that bend.

02:28:20.040 --> 02:28:24.040
That gets it roughly in line this direction, which is nice.

02:28:24.040 --> 02:28:28.040
Then I just have to do one of these. Oh my god.

02:28:28.040 --> 02:28:30.040
Oh please.

02:28:32.040 --> 02:28:35.040
That's mercy. That's mercy.

02:28:50.040 --> 02:28:54.040
This is where I learned all the regrets that I'm about to have.

02:28:54.040 --> 02:28:58.040
Okay, holy moly.

02:28:58.040 --> 02:29:04.040
Okay. Lord, that was awful.

02:29:04.040 --> 02:29:08.040
But it almost worked. That's entertaining.

02:29:08.040 --> 02:29:12.040
I'm going to flip it over because I've essentially lined it up to be that now.

02:29:12.040 --> 02:29:16.040
Wow, that went much better than I expected.

02:29:16.040 --> 02:29:22.040
So I need a little more bend here. Oh god.

02:29:22.040 --> 02:29:26.040
It's fine.

02:29:26.040 --> 02:29:30.040
It's fine. It's fine.

02:29:30.040 --> 02:29:34.040
I definitely didn't crush the tube a bit.

02:29:34.040 --> 02:29:38.040
Okay, so that's actually really, really, really, really close.

02:29:38.040 --> 02:29:44.040
So I have this fitting to there. And then this one just needs to straighten it out down here.

02:29:44.040 --> 02:29:48.040
Holy moly, that's a sharp bend, which is not great.

02:30:00.040 --> 02:30:02.040
Maybe.

02:30:04.040 --> 02:30:08.040
No, I need to bend it down more.

02:30:08.040 --> 02:30:14.040
It's getting there.

02:30:14.040 --> 02:30:20.040
How's that? That's actually probably close enough.

02:30:20.040 --> 02:30:26.040
Yeah, that'll do. Okay, now I just have to cut this down and then do some jank.

02:30:26.040 --> 02:30:30.040
So I'll cut it like there.

02:30:30.040 --> 02:30:34.040
Whee! More pipe cutting.

02:30:34.040 --> 02:30:44.040
Oh, this is going to suck now. That's really shitty.

02:30:44.040 --> 02:30:50.040
The reason this is going to suck now. Oh, never mind.

02:30:50.040 --> 02:30:56.040
I cleared it because the two pipes aren't parallel.

02:30:56.040 --> 02:31:00.040
Thankfully it doesn't matter because soft copper is soft and I can just make it work.

02:31:06.040 --> 02:31:12.040
There it goes.

02:31:12.040 --> 02:31:16.040
Okay. A little bit of deburring.

02:31:26.040 --> 02:31:30.040
Okay. Okay.

02:31:34.040 --> 02:31:38.040
Wow, that actually worked. Holy moly.

02:31:38.040 --> 02:31:42.040
I have a coil! It's not straight.

02:31:44.040 --> 02:31:48.040
It's straight when the capacitor is sideways. That's fine.

02:31:48.040 --> 02:31:52.040
I can fix that later. That's a low priority problem.

02:31:58.040 --> 02:32:02.040
Alright, hand tight.

02:32:04.040 --> 02:32:12.040
Hand tight. And then just for the sake of consistency, I know there is a correct way.

02:32:12.040 --> 02:32:16.040
And it's nowhere near as much as I'm doing it. I don't care.

02:32:18.040 --> 02:32:22.040
Let's go to three quarter.

02:32:22.040 --> 02:32:24.040
Perfect.

02:32:28.040 --> 02:32:36.040
I'm only going to do this one to half. Because in order to test this, I need to put a matching transformer on it.

02:32:36.040 --> 02:32:40.040
Which means I need to take one of these off. Ha!

02:32:40.040 --> 02:32:44.040
So close. But wait, I actually might...

02:32:44.040 --> 02:32:48.040
No, I shouldn't take both off. That's fine.

02:32:48.040 --> 02:32:52.040
That doesn't mean I'm taking these... These screws.

02:32:52.040 --> 02:32:56.040
Wrenches. With me.

02:32:58.040 --> 02:33:00.040
Good enough.

02:33:02.040 --> 02:33:06.040
Neither of those are going anywhere. Good, good, good.

02:33:06.040 --> 02:33:12.040
Taking these with me. I should not need any more stuff.

02:33:12.040 --> 02:33:16.040
In terms of the cutting or the bending or the blah, blah, blah.

02:33:16.040 --> 02:33:20.040
Because all of the other connections on this setup are going to be plastic.

02:33:20.040 --> 02:33:24.040
Because I don't want to short this to everything else. That would be very bad.

02:33:24.040 --> 02:33:28.040
I've gotten everything assembled together. And this is where things start getting a little scary.

02:33:28.040 --> 02:33:32.040
So... Nope.

02:33:32.040 --> 02:33:36.040
I have my first driver circuit.

02:33:36.040 --> 02:33:40.040
Powering the second driver circuit. Going into the IGBT blocks.

02:33:40.040 --> 02:33:44.040
Which takes power through this full board rectifier.

02:33:44.040 --> 02:33:50.040
I have a nice current clamp. Which can give me a current reading times ten.

02:33:50.040 --> 02:33:54.040
On that. I also have another meter for voltage.

02:33:54.040 --> 02:34:00.040
And I have a variac. So I can drop what the voltage going into this is.

02:34:00.040 --> 02:34:04.040
So I'm not going at 120 or half the bat. After that it goes into this.

02:34:04.040 --> 02:34:10.040
I have a nice capacitor here. And then the outputs of this go into this driving toroid.

02:34:10.040 --> 02:34:18.040
Which is probably not great. And that couples to the work coil and the tank capacitor.

02:34:18.040 --> 02:34:22.040
So that's all set up and fun.

02:34:22.040 --> 02:34:26.040
Now for the glorious time. I'm turning the freaking thing on.

02:34:26.040 --> 02:34:30.040
So first off.

02:34:30.040 --> 02:34:34.040
Watching the current. As I turn on the variac.

02:34:34.040 --> 02:34:40.040
It's going to peak and then come back down. That is just from charging this capacitor.

02:34:40.040 --> 02:34:44.040
I believe at this particular juncture.

02:34:44.040 --> 02:34:48.040
That variac is at about 70 volts. I'm currently set to DC.

02:34:48.040 --> 02:34:56.040
So probing across that. I'm looking at a nice 77 volts DC.

02:34:56.040 --> 02:35:00.040
Okay. I then have turned that off for this.

02:35:00.040 --> 02:35:04.040
This is the power supply for the driving circuits.

02:35:04.040 --> 02:35:10.040
So when I turn that on. The thing to watch is that number right there.

02:35:10.040 --> 02:35:14.040
And to see if the variac starts smoking again.

02:35:14.040 --> 02:35:18.040
Holy crap.

02:35:18.040 --> 02:35:24.040
Okay. I am fairly sure that was the variac.

02:35:24.040 --> 02:35:32.040
And if that current clamp is correct. I was drawing 22 amps.

02:35:32.040 --> 02:35:38.040
Somehow. That should have blown a long list of breakers.

02:35:38.040 --> 02:35:42.040
Or safeties. Number one.

02:35:42.040 --> 02:35:48.040
With that freaking fuse. Which is clearly not doing a damn thing.

02:35:48.040 --> 02:35:56.040
Okay. Okay then.

02:35:56.040 --> 02:36:02.040
If that wasn't actually about to vibrate off of the freaking table.

02:36:02.040 --> 02:36:08.040
I would have done some more testing. But at the moment I kind of can't.

02:36:08.040 --> 02:36:12.040
Just do a little bit of measuring. That's not too hot.

02:36:12.040 --> 02:36:16.040
That's relatively warm.

02:36:16.040 --> 02:36:20.040
That's fine. That's fine.

02:36:20.040 --> 02:36:24.040
That's fine. Very not clean.

02:36:24.040 --> 02:36:28.040
Not. Seems to not be too hot.

02:36:28.040 --> 02:36:34.040
But. Troubleshooting to follow.

02:36:34.040 --> 02:36:38.040
Now's the time to actually start assembling everything together.

02:36:38.040 --> 02:36:42.040
And quite possibly in the case too. I made a couple of realizations here and there.

02:36:42.040 --> 02:36:46.040
Through some testing. Number one.

02:36:46.040 --> 02:36:52.040
The driving coil. The coupling transformer between the driving circuit.

02:36:52.040 --> 02:36:56.040
Or the power circuit. And the work tank.

02:36:56.040 --> 02:37:00.040
I pretty much shorted it. Not actually but I was running.

02:37:00.040 --> 02:37:06.040
According to the impedance of it. I was running probably north of like 30 amps.

02:37:06.040 --> 02:37:10.040
Through it at peak. I think some breakers in testing.

02:37:10.040 --> 02:37:14.040
I swapped it out. Swapped out the cable.

02:37:14.040 --> 02:37:20.040
Which I might have somewhere. I swapped out the thinner gauge cable that I used for testing.

02:37:20.040 --> 02:37:24.040
With my six gauge super chonker wire.

02:37:24.040 --> 02:37:28.040
I crimped on some nice beef cake terminals.

02:37:28.040 --> 02:37:34.040
Terminations on the two ends. And I wound this up so it shouldn't overdraw current.

02:37:34.040 --> 02:37:38.040
While still powering this with plenty of room to spare.

02:37:40.040 --> 02:37:46.040
I also have a water cooling setup. Because now that I'm actually looking at doing full power tests.

02:37:46.040 --> 02:37:49.040
This work coil is going to heat up really fast.

02:37:49.040 --> 02:37:54.040
Though it only has like .08 of an O or something insane like that.

02:37:54.040 --> 02:37:57.040
When you're running hundreds of amps through it.

02:37:57.040 --> 02:38:01.040
That still adds up really fast to a lot of power.

02:38:01.040 --> 02:38:08.040
So I need to actually water cool stuff. Where things are going to start having big problems.

02:38:08.040 --> 02:38:13.040
I'm also going to swap to my nice little janktastic power supply.

02:38:13.040 --> 02:38:16.040
That has given it's life for this project.

02:38:16.040 --> 02:38:20.040
To drive the driving circuitry.

02:38:20.040 --> 02:38:26.040
And I have our nice 240 to 120 adapter power cable.

02:38:26.040 --> 02:38:29.040
Which we don't use for anything. Because it's really unsafe.

02:38:29.040 --> 02:38:33.040
So explicitly use it. Because you know you need to use it.

02:38:33.040 --> 02:38:36.040
Now I'm going to go to a bunch of putting stuff together.

02:38:36.040 --> 02:38:40.040
And I'll talk to you when everything's assembled. Everything's all hooked up.

02:38:40.040 --> 02:38:43.040
Now I get to do a quick leak check.

02:38:43.040 --> 02:38:47.040
Because I don't trust this.

02:38:47.040 --> 02:38:49.040
And I don't trust this.

02:38:53.040 --> 02:38:57.040
Alright now it's time to do a leak check. After hooking everything up.

02:38:57.040 --> 02:39:00.040
Out of the case.

02:39:00.040 --> 02:39:05.040
I trust these fittings over here. On the water on the res.

02:39:05.040 --> 02:39:09.040
I do not trust these in the slightest. So I have a nice little catch underneath.

02:39:09.040 --> 02:39:15.040
Just in case it leaks. And then I don't really trust these wage lock fittings on these pipes.

02:39:15.040 --> 02:39:19.040
I feel like the soft copper is too soft. For these to work properly.

02:39:19.040 --> 02:39:23.040
So these very well may leak. And I may have to swap these out for something else.

02:39:23.040 --> 02:39:26.040
Across that bridge if I have to. I'm hoping I won't.

02:39:26.040 --> 02:39:33.040
But I definitely want to leak check. Before I go and put like hundreds of volts across here.

02:39:33.040 --> 02:39:38.040
And then have water leaking. Because that's just begging for a tremendous disaster.

02:39:41.040 --> 02:39:45.040
But now I get to have the adventure of actually making it happen.

02:39:51.040 --> 02:39:53.040
Alright.

02:39:54.040 --> 02:39:57.040
This bad boy up.

02:40:00.040 --> 02:40:02.040
Actually going to disconnect.

02:40:06.040 --> 02:40:08.040
These PCIe plugs.

02:40:11.040 --> 02:40:16.040
Come in. There you go. And plug in a little more leaks.

02:40:17.040 --> 02:40:24.040
Conveniently this power supply is old enough that it still has that.

02:40:27.040 --> 02:40:28.040
Okay.

02:40:30.040 --> 02:40:31.040
Go.

02:40:33.040 --> 02:40:37.040
I guess that hole is actually small enough that I will use the proper filler.

02:40:46.040 --> 02:40:47.040
Okay.

02:40:55.040 --> 02:40:58.040
I likely will not have to top this up.

02:40:58.040 --> 02:41:04.040
I think the volume of this loop is small enough that I don't have to care.

02:41:08.040 --> 02:41:15.040
Okay. Conveniently I also have a nice little thumb switch for this power supply.

02:41:15.040 --> 02:41:16.040
But here we go.

02:41:19.040 --> 02:41:23.040
Turned off the power supply. Here we go again.

02:41:26.040 --> 02:41:28.040
Yeah, yeah, yeah, yeah, yeah.

02:41:30.040 --> 02:41:33.040
And off. So far so good.

02:41:33.040 --> 02:41:36.040
Nothing is immediately leaking.

02:41:36.040 --> 02:41:43.040
That's a win. There's also very little resistance in this loop overall with the power of this pump.

02:41:44.040 --> 02:41:47.040
So that's playing to my benefit as well.

02:41:48.040 --> 02:41:54.040
All right. I'm going to cap this in case this decides to tip itself over in classic.

02:41:54.040 --> 02:42:02.040
If anything go wrong, can go in there. I'm just going to cap this off just in case in classic Murphy's Law fashion,

02:42:02.040 --> 02:42:05.040
anything that's going to go wrong will go wrong.

02:42:07.040 --> 02:42:11.040
Pump this on that one more time. Just let it run for a bit.

02:42:11.040 --> 02:42:16.040
In the long run, I'll likely put one of the return up here.

02:42:17.040 --> 02:42:24.040
So I will hopefully be able to actually drain the loop so I can swap the coil out.

02:42:28.040 --> 02:42:31.040
That looks pretty good. Okay.

02:42:32.040 --> 02:42:34.040
Nothing is leaking.

02:42:35.040 --> 02:42:37.040
Nothing is leaking.

02:42:38.040 --> 02:42:46.040
Parimo. Okay. This is now a very much safety glasses and do not try at home territory.

02:42:48.040 --> 02:42:51.040
Take everything, plug it all in.

02:42:53.040 --> 02:43:00.040
Before I do that, just going to remove everything metal from close by.

02:43:07.040 --> 02:43:20.040
These are very much not voltage rated, but they're better than nothing.

02:43:20.040 --> 02:43:22.040
I know they're not voltage rated.

02:43:23.040 --> 02:43:26.040
So it will not act as though they are.

02:43:26.040 --> 02:43:31.040
We have the gas, people over clubs. Again, not ESD rated.

02:43:31.040 --> 02:43:34.040
And I'm not going to treat them like they are.

02:43:34.040 --> 02:43:42.040
But for the first time I'm setting this up, it is better than nothing.

02:43:43.040 --> 02:43:52.040
So welding glove inside butyl rubber glove is going to be the best I'm going to get.

02:43:53.040 --> 02:43:59.040
I'm going to actually get the other hand. I have now made it so the power supply will stay on.

02:44:00.040 --> 02:44:05.040
So I will likely do control of the overall system from the variac.

02:44:05.040 --> 02:44:07.040
So that's the power on the power side.

02:44:08.040 --> 02:44:09.040
At four amps.

02:44:11.040 --> 02:44:14.040
Yeah, that's like workable.

02:44:15.040 --> 02:44:21.040
That's four amps at probably about 20 volts DC-ish or 15 volts AC.

02:44:21.040 --> 02:44:23.040
So let's hit it.

02:44:24.040 --> 02:44:26.040
Hit it. Okay.

02:44:27.040 --> 02:44:31.040
Nothing. Right. Didn't turn on the current line.

02:44:31.040 --> 02:44:34.040
That's right.

02:44:34.040 --> 02:44:37.040
Okay. Let's turn that off.

02:44:37.040 --> 02:44:39.040
Re-zero this.

02:44:44.040 --> 02:44:47.040
Right. Didn't turn on the power supply.

02:44:50.040 --> 02:44:55.040
Driving circuitry is on. Variac is on.

02:44:55.040 --> 02:44:58.040
Four amps. Primo.

02:44:58.040 --> 02:45:01.040
Primo. Perfect. Awesome.

02:45:04.040 --> 02:45:10.040
So it's only drawing two amps now because putting the steel bar in loads the work coil more.

02:45:13.040 --> 02:45:17.040
I'm just going to let this sit for a bit. It's warm.

02:45:17.040 --> 02:45:19.040
Heck yeah bud.

02:45:20.040 --> 02:45:22.040
Heck yeah bud. Okay.

02:45:23.040 --> 02:45:28.040
Let's do a little more. So this thing is definitely not rated for anywhere near 20 amps.

02:45:28.040 --> 02:45:32.040
Because it's already starting to sound unhappy. Let's do the thing.

02:45:33.040 --> 02:45:36.040
Holy crap. Yeah, that's hot.

02:45:36.040 --> 02:45:40.040
Not burning you hot, but uncomfortable to touch hot.

02:45:41.040 --> 02:45:43.040
Ha ha ha.

02:45:44.040 --> 02:45:46.040
It does the thing.

02:45:47.040 --> 02:45:52.040
Heck yeah buddy. Kind of want to try to heat something up enough that you can see it.

02:45:54.040 --> 02:45:57.040
This is too, probably a little too thick.

02:46:07.040 --> 02:46:12.040
Okay. This is probably some grade of stainless.

02:46:15.040 --> 02:46:19.040
Yeah, it's already pulled down quite a bit. So I'll stick this in.

02:46:19.040 --> 02:46:23.040
Oh, it's still going. No, that's not smart, but whatever.

02:46:29.040 --> 02:46:34.040
Ha. So that does pretty much nothing.

02:46:34.040 --> 02:46:37.040
Conveniently the IGBT blocks are not very hot.

02:46:39.040 --> 02:46:44.040
But that's probably because they're just hilariously under their rated spec right now.

02:46:44.040 --> 02:46:48.040
This is operating at maybe 30 volts or 40 volts.

02:46:48.040 --> 02:46:52.040
Yeah, it's hot, but this is not really for a magnetic.

02:46:52.040 --> 02:46:56.040
So it doesn't heat up nearly as quickly. All right, let's go back to the bar.

02:46:56.040 --> 02:46:59.040
And this is well below what this setup can handle.

02:46:59.040 --> 02:47:02.040
Especially now that I've water cooled the coil.

02:47:03.040 --> 02:47:07.040
Other than the fact that the variac is buzzing like nobody's fricking business.

02:47:07.040 --> 02:47:10.040
This thing can handle way more power.

02:47:10.040 --> 02:47:16.040
So the metal is starting to discolor from it being so hot that it's oxidizing.

02:47:17.040 --> 02:47:20.040
This is now no longer in touch test territory.

02:47:21.040 --> 02:47:25.040
Yeah, so that's really hot.

02:47:25.040 --> 02:47:31.040
I'm not touching that. There is zero chance in heck that I am touching that.

02:47:33.040 --> 02:47:36.040
It smells hot, a little hot.

02:47:40.040 --> 02:47:44.040
So that's fun. It works.

02:47:45.040 --> 02:47:48.040
That was at 40 volts.

02:47:53.040 --> 02:47:57.040
And this thing should be able to handle with no problem.

02:47:59.040 --> 02:48:02.040
200 on the input.

02:48:03.040 --> 02:48:08.040
This is going to be fun because that'll heat up really fast.

02:48:09.040 --> 02:48:12.040
Just for just for kicks.

02:48:13.040 --> 02:48:17.040
Everything should be safe now. I drained it.

02:48:17.040 --> 02:48:21.040
I disconnected the thing.

02:48:21.040 --> 02:48:26.040
I discharged it. Heck yeah buddy.

02:48:26.040 --> 02:48:30.040
Okay, sick. Now my job is to fit this into the box.

02:48:33.040 --> 02:48:36.040
Sorry for the hilariously shaky hand.

02:48:36.040 --> 02:48:39.040
Found a couple of issues at the case.

02:48:39.040 --> 02:48:44.040
And made a couple of parts that I realized are just not going to work in the slightest.

02:48:45.040 --> 02:48:51.040
I cut out a couple of nice little sheets to act as fronts for in here.

02:48:51.040 --> 02:48:56.040
That would go in here, hold these pipes in place and would work all hunky-dory.

02:48:56.040 --> 02:49:01.040
But then I realized I wanted to be able to have these fully inside the case with this closed.

02:49:01.040 --> 02:49:04.040
So these do literally nothing.

02:49:04.040 --> 02:49:08.040
I'm going to have to swap these out and have some mounts on here instead,

02:49:08.040 --> 02:49:14.040
which is just a little bit further back on this piece here instead of this front piece.

02:49:14.040 --> 02:49:21.040
Second, I swapped which side these Molex power cables are for the fans.

02:49:21.040 --> 02:49:24.040
This side is going to be really busy anyway.

02:49:25.040 --> 02:49:30.040
This side is going to be really busy anyway. And honestly, I just don't want to have more stuff over here.

02:49:30.040 --> 02:49:36.040
Third, I'm going to have to shorten those copper tubes, which is rather unfortunate.

02:49:36.040 --> 02:49:39.040
I'm likely going to shorten both sides.

02:49:40.040 --> 02:49:47.040
I'll probably cut it off around here on this side and then probably just shorten this up just a touch.

02:49:47.040 --> 02:49:55.040
So I can have the capacitor sitting much closer to the front have enough room to run the tubes down and underneath this fan.

02:49:55.040 --> 02:50:02.040
So I can have all three fans populated just to give myself some extra headroom for lots of power later if I need it.

02:50:04.040 --> 02:50:07.040
But this is the very, very empty case.

02:50:07.040 --> 02:50:11.040
It's good fun. There's going to be a couple more holes chopped into the front.

02:50:11.040 --> 02:50:20.040
I'm going to open that up a ton for more airflow like we remove that center acrylic piece and install a whole bunch of other fun stuff.

02:50:20.040 --> 02:50:24.040
And there is everything that's going to have to go in here.

02:50:25.040 --> 02:50:27.040
I think one of the Starbucks cups.

02:50:28.040 --> 02:50:33.040
Oh yeah, I also took those covers off from here because all I don't need them.

02:50:34.040 --> 02:50:41.040
Anyway, so you'll lighter in case anyone was ever curious who hasn't worked with switch lock fittings before.

02:50:42.040 --> 02:50:47.040
These compression parts do actually shrink when you crush it.

02:50:47.040 --> 02:51:05.040
So the inner diameter of these holes reduced by a non-trivial fraction, which means I did some things that you definitely shouldn't do like hammer these pieces on to the copper tube to get it to fit again.

02:51:05.040 --> 02:51:10.040
Ha! This is going to be a tall glass of things not to do at home.

02:51:10.040 --> 02:51:16.040
Let's just ignore the horrific, horrific, horrific, awful things that I've done to this poor power supply.

02:51:16.040 --> 02:51:26.040
I will make it significantly less gross eventually, but right now I just needed to get rid of a ton of cabling because I thought I didn't have a lot of space.

02:51:26.040 --> 02:51:28.040
Turns out I kind of do.

02:51:29.040 --> 02:51:34.040
I might actually be able to fit the gigantic capacitor in this just for shits and giggles because I can.

02:51:34.040 --> 02:51:44.040
We'll see. But back here is going to be all of the cooling, all of the water cooling runs, as well as the power inputs.

02:51:44.040 --> 02:51:48.040
So this is going to be the main power for the high power side.

02:51:48.040 --> 02:51:53.040
Goes into the switch, which goes into these breakers, which may or may not be high rated enough.

02:51:53.040 --> 02:51:55.040
I have to do some math.

02:51:56.040 --> 02:52:07.040
Goes out of the breakers into the three-phase full-bridge rectifier, which then is going to have to run underneath this chonk-tastic rad.

02:52:07.040 --> 02:52:13.040
This fan and connect up here to the two bus bars on the inverter block.

02:52:15.040 --> 02:52:22.040
I may end up plonking the humongous cap right here just for kicks if I can, if not, whatever.

02:52:23.040 --> 02:52:33.040
But this is, yeah, so the inverter blocks here, that's going to be connected to these two caps unless I can fit the gigantic one in the back.

02:52:33.040 --> 02:52:37.040
I have my two driving boards.

02:52:37.040 --> 02:52:41.040
These very well may get moved over here.

02:52:41.040 --> 02:52:50.040
I may end up shifting some stuff around just so I have more space to work with and extending these connections for the output of this board.

02:52:50.040 --> 02:52:53.040
It goes into the inverter block.

02:52:53.040 --> 02:52:57.040
Then I have my high power cap with the coupling toroid.

02:52:57.040 --> 02:53:00.040
I'm almost certainly going to have to rewind this.

02:53:00.040 --> 02:53:09.040
It's just too loose and with the amount of space I have in that area, all of this extra space is actually hurting me quite a bit.

02:53:09.040 --> 02:53:16.040
Turns out I shot myself in the foot kind of aggressively and I cut these tubes really short.

02:53:16.040 --> 02:53:23.040
So it's actually difficult to get this coupling transformer around the tubes.

02:53:23.040 --> 02:53:26.040
Ha ha, whoops, let me learn.

02:53:26.040 --> 02:53:34.040
Once that's set up, then the whatever work coil I'm using will connect onto these and that's the electronic side.

02:53:34.040 --> 02:53:44.040
Then onto the water cooling side, I have Le Pomp, the gigantic, not res.

02:53:44.040 --> 02:53:50.040
I have Le Pomp, the super thick boy Ikea rad.

02:53:50.040 --> 02:53:58.040
I have the capacitor line or the capacitor loop, which obviously is open right now because the coil needs to be on it.

02:53:58.040 --> 02:54:02.040
Then I have the inverter block loop.

02:54:02.040 --> 02:54:08.040
My current thought is I want to make sure that that cap doesn't get too hot because it is expensive and difficult to source.

02:54:08.040 --> 02:54:13.040
Everything else in here is much easier to replace, so I want to make sure that that stays cool enough.

02:54:13.040 --> 02:54:21.040
So my plan is output of RAT, one of those I have yet, for computer devices.

02:54:21.040 --> 02:54:29.040
The temperature drop across the radiator is generally speaking quite small and the temperature of your entire loop will be essentially equal.

02:54:29.040 --> 02:54:41.040
For this, because I'm working in bursts, the order that I put the parts in actually matters or can matter.

02:54:41.040 --> 02:54:50.040
So I want to have my most critical or my most temperature sensitive parts first and then continue down the chain.

02:54:50.040 --> 02:54:54.040
So first thing is the cap, but that's going to be the output of the radiator.

02:54:54.040 --> 02:54:57.040
So output of the radiator is going to go at the input of the capacitor loop.

02:54:57.040 --> 02:55:05.040
The output of the capacitor loop is going to go to either the input of the inverter block loop or potentially the pump.

02:55:05.040 --> 02:55:12.040
I haven't decided yet. And then the output of the pump is going to go either to this.

02:55:12.040 --> 02:55:20.040
Well, yeah, in the case that the capacitor connects directly to the pump, the output of the pump goes to the inverter block.

02:55:20.040 --> 02:55:28.040
The output of the inverter block goes back into the rad or you flip the pump and the inverter block.

02:55:28.040 --> 02:55:31.040
We'll see, but it's coming together.

02:55:31.040 --> 02:55:35.040
Holy crap. I still have a whole bunch of stuff to do up here.

02:55:35.040 --> 02:55:39.040
I have to remove a whole bunch of this material, this metal.

02:55:39.040 --> 02:55:45.040
I also have to put in a nice little power switch for actually turning on this circuit.

02:55:45.040 --> 02:55:50.040
And then I have fairly easy access to this potentiometer.

02:55:50.040 --> 02:56:02.040
I may end up desoldering this particular pot like this, this physical pot and reconnecting it to the front right beside the switch so I can adjust the frequency on the fly.

02:56:02.040 --> 02:56:15.040
I will also still have, I also want to mount this bad boy to the front as well so I can read it, read out how much power is going into the system.

02:56:15.040 --> 02:56:27.040
I'm not sure exactly where this is going to, this is going to end up yet because unfortunately I'm going to have to get this or that part right there.

02:56:27.040 --> 02:56:38.040
So there's going to be some non-trivial wiring runs for that, but I think it's not pulling very much power so it doesn't matter too, too much.

02:56:38.040 --> 02:56:47.040
I love it when a plan starts coming together. This is starting to actually look legit, which let's say I am a list-ducked, but it's coming together.

02:56:47.040 --> 02:56:57.040
Hell yeah. Oh, late night. I will see you another day whenever I can find more time to actually finish this monster of a project.

02:57:00.040 --> 02:57:06.040
I just experienced a couple of iterations of, oh yeah, right, if you're flipping something over, it's not necessarily the same.

02:57:06.040 --> 02:57:11.040
But I started off having this as my capacitor holder.

02:57:11.040 --> 02:57:14.040
It's just not great for a lot of reasons.

02:57:14.040 --> 02:57:25.040
The sizing and the tolerances on all of these parts are just not good and the layer lines for the 3D prints are actually like scratching away at the paper on the capacitor.

02:57:25.040 --> 02:57:34.040
So these, no bueno, also they're two separate parts, which was kind of nice for modularity and the ability to try to clamp it sideways, but that just didn't work out.

02:57:34.040 --> 02:57:38.040
And I decided that I was only going to put two holes in the actual box itself.

02:57:38.040 --> 02:57:42.040
So I redesigned it to be something like this.

02:57:42.040 --> 02:57:46.040
So it'll sit, hopefully, nice and in there.

02:57:46.040 --> 02:57:54.040
Have a little bit of wibble wobble, but I can put a top on it, clamp it down, Bob's your uncle good to go.

02:57:54.040 --> 02:58:01.040
But when I went to make it, I made the bottom piece. This is not symmetric.

02:58:01.040 --> 02:58:05.040
And this bottom piece printed off really well. It looks really good.

02:58:05.040 --> 02:58:08.040
I printed the top piece at the same time. It looks great.

02:58:08.040 --> 02:58:16.040
Except I, to make this, I just chopped the bottom off, which means the holes line up this way.

02:58:16.040 --> 02:58:21.040
But when I go to put them together, the holes don't line up.

02:58:21.040 --> 02:58:29.040
So I get to remake the top part because face palm, but it's nothing too bad.

02:58:29.040 --> 02:58:36.040
I'm also going to, you know, make some additional chamfers and fillets to round off all of these edges on the outside of this part.

02:58:36.040 --> 02:58:40.040
But that's on the printers right now. And once that's done, I'll get this together.

02:58:40.040 --> 02:58:43.040
Also, this does fit onto the holes that I've made.

02:58:43.040 --> 02:58:49.040
Other detail, I forgot to add chamfers to the bottoms of these holes.

02:58:49.040 --> 02:58:57.040
So I'm going to get to do that in a sketchy fashion, let's say, but you'll get to see that soon.

02:58:57.040 --> 02:59:03.040
Came up with several different ways to try to do this in varying levels of takes forever and sketchy.

02:59:03.040 --> 02:59:08.040
This is kind of in the middle, more towards the sketchy side.

02:59:08.040 --> 02:59:11.040
Just adding a nice little chamfer on the bottom. It'll be fine.

02:59:11.040 --> 02:59:15.040
Famous last words, if ever have I said them.

02:59:15.040 --> 02:59:17.040
Oh, right.

02:59:28.040 --> 02:59:31.040
That actually works super well.

02:59:31.040 --> 02:59:36.040
Nice little chamfer. Now this one's going to be a little more spicy except to move it along the cut.

02:59:36.040 --> 02:59:40.040
But yeah, good.

02:59:40.040 --> 02:59:44.040
Now it's as good a time as any to get to try.

02:59:57.040 --> 03:00:11.040
Well, it's definitely not pretty, but that'll do.

03:00:11.040 --> 03:00:16.040
Only doing this one time because after I do it once, it's not going to be as exciting.

03:00:16.040 --> 03:00:20.040
So I know what's going to happen.

03:00:20.040 --> 03:00:23.040
I have my variac plugged into a wall outlet.

03:00:23.040 --> 03:00:32.040
The output of which is getting measured by a multimeter and also the full system through this little beast here.

03:00:32.040 --> 03:00:35.040
This probably won't turn on until like 60 volts.

03:00:35.040 --> 03:00:41.040
I'm guessing based on the ones I've used in the past.

03:00:41.040 --> 03:00:47.040
In here, I have several layers of switching and power and stuff.

03:00:47.040 --> 03:00:57.040
So the inlet from the variac or a wall outlet or whatever I'm putting into the system goes through this chunky switch contactor.

03:00:57.040 --> 03:01:04.040
That contactor then goes through a breaker, which is rated, I believe at 16 amps.

03:01:04.040 --> 03:01:08.040
I'm probably going to have to change it out at some point, but that's a later problem.

03:01:08.040 --> 03:01:12.040
And then it goes into the actual system through direct fire and everything else.

03:01:12.040 --> 03:01:16.040
These two are the first two main power on devices.

03:01:16.040 --> 03:01:22.040
So I'm going to start with this off just to make sure that nothing crazy is happening.

03:01:22.040 --> 03:01:29.040
And I'll start the variac very low, probably go up to about 80 to maybe 100 volts DC or AC.

03:01:29.040 --> 03:01:35.040
And then I'll go back down, turn up, hit the switch and then start loading the whole system.

03:01:35.040 --> 03:01:41.040
I'm not turning on the driving circuitry because I don't even have the work coil in here.

03:01:41.040 --> 03:01:54.040
And I just don't want to mess with that. So safety glasses because some weirdness might happen.

03:01:54.040 --> 03:01:58.040
That's fine. Don't worry about it. Okay, so power on.

03:01:58.040 --> 03:02:03.040
So I'm getting like half of all AC, so pretty much nothing.

03:02:04.040 --> 03:02:12.040
And just as a quick sanity check, let's go up to like 30.

03:02:12.040 --> 03:02:17.040
Good enough. I want to measure in here.

03:02:21.040 --> 03:02:27.040
Nothing perfect. So that means the contractor works as it should.

03:02:27.040 --> 03:02:32.040
But you know, you'd rather check going to turn this back down.

03:02:32.040 --> 03:02:36.040
And I'm going to hit the contractor to be on.

03:02:36.040 --> 03:02:40.040
This is now hot. Okay.

03:02:40.040 --> 03:02:44.040
Oh, let's see when this little bugger turns on.

03:02:44.040 --> 03:02:48.040
Oh, okay.

03:02:48.040 --> 03:02:51.040
That was unexpected.

03:02:51.040 --> 03:02:57.040
This started vibrating right away, which I was definitely not expecting.

03:02:57.040 --> 03:03:03.040
Something is not right. Okay. Time to do a little bit of measuring because something's not behaving.

03:03:03.040 --> 03:03:07.040
0.3 volts there. Yeah. Okay. That makes sense.

03:03:07.040 --> 03:03:25.040
Back at it again. I have now disconnected the coupling trolley because I have a sneaking suspicion that without a controlling signal coming from the driving circuits for the inverter block, it might try to be trying to short out through this coil.

03:03:25.040 --> 03:03:28.040
So I'm just going to try disconnecting that entirely.

03:03:28.040 --> 03:03:32.040
And then I will repeat what I have done before.

03:03:32.040 --> 03:03:47.040
This time I'm actually just going to be measuring the DC side rather than the AC side because I already have a measurement on the AC side here after 45 volts.

03:03:47.040 --> 03:03:52.040
So let's give her another little send.

03:03:52.040 --> 03:03:58.040
Okay. So effectively nothing.

03:03:58.040 --> 03:04:02.040
I don't like that because...

03:04:02.040 --> 03:04:06.040
Yeah, that voltage drops way too fast.

03:04:06.040 --> 03:04:09.040
Okay.

03:04:09.040 --> 03:04:14.040
I guess I get to power the supply now.

03:04:14.040 --> 03:04:18.040
I would rather not.

03:04:18.040 --> 03:04:25.040
On the right side, I have a nice power switch to not drive the circuitry.

03:04:25.040 --> 03:04:30.040
And also, if all else fails, I don't even have a work coil connected.

03:04:30.040 --> 03:04:36.040
So nothing too, too bad should happen.

03:04:36.040 --> 03:04:47.040
Okay. So let's hit this.

03:04:47.040 --> 03:04:50.040
Okay, that fan just like cranks it.

03:04:50.040 --> 03:04:57.040
But I'm wondering if that just does that anyway, even if there's no load at all.

03:04:57.040 --> 03:05:02.040
Where, where, I'm probing across.

03:05:02.040 --> 03:05:16.040
From there to there.

03:05:16.040 --> 03:05:22.040
Okay, so that's my 12 volts on the gates on the drive side one.

03:05:22.040 --> 03:05:30.040
And then on...

03:05:30.040 --> 03:05:38.040
So there's nothing coming out of the initial, the first stage of my drive circuitry, which is great.

03:05:38.040 --> 03:05:43.040
That probably means that this power supply is just always going to give her.

03:05:43.040 --> 03:05:46.040
I'm kind of okay with that.

03:05:46.040 --> 03:05:51.040
I might want to open up and give it a little more room to breathe, but that's a later problem.

03:05:51.040 --> 03:06:08.040
So now what I want to do is turn it on again.

03:06:08.040 --> 03:06:25.040
Okay, so it's measuring 0.2 volts and change still.

03:06:25.040 --> 03:06:38.040
That was not good. I felt some tingles.

03:06:38.040 --> 03:06:42.040
Something is isolated well enough here.

03:06:42.040 --> 03:06:49.040
Okay, so what's my resistance to chassis?

03:06:49.040 --> 03:06:55.040
That's a good first check.

03:06:55.040 --> 03:07:00.040
2 mega ohms.

03:07:00.040 --> 03:07:07.040
Negative, that's not a good start.

03:07:07.040 --> 03:07:10.040
1.9 mega ohms.

03:07:10.040 --> 03:07:22.040
This capacitor is probably still discharging.

03:07:22.040 --> 03:07:31.040
I was right.

03:07:31.040 --> 03:07:43.040
The capacitor is going to slightly recharge anyway.

03:07:43.040 --> 03:07:48.040
Excuse me? What now?

03:07:48.040 --> 03:07:51.040
That's not good.

03:07:51.040 --> 03:08:01.040
23 kilo ohms is a little bit low.

03:08:01.040 --> 03:08:11.040
Why is there only 14k to ground?

03:08:11.040 --> 03:08:15.040
What?

03:08:15.040 --> 03:08:19.040
Something's wrong.

03:08:19.040 --> 03:08:23.040
Something is like legitimately wrong.

03:08:23.040 --> 03:08:29.040
I'm just going to unplug this.

03:08:29.040 --> 03:08:33.040
Oh, you're actually kidding me, right?

03:08:33.040 --> 03:08:36.040
You're actually kidding me.

03:08:36.040 --> 03:08:42.040
Okay, then.

03:08:42.040 --> 03:08:55.040
So this thing is a disaster waiting to happen.

03:08:55.040 --> 03:09:03.040
Just as a sanity check first. Holy shit.

03:09:03.040 --> 03:09:08.040
Oh my god.

03:09:08.040 --> 03:09:11.040
Okay then.

03:09:11.040 --> 03:09:20.040
So this variac is going to kill someone.

03:09:20.040 --> 03:09:25.040
I'm going to have to break this thing apart and figure out why it's doing what it's doing.

03:09:25.040 --> 03:09:32.040
It is, it appears to be a dead short.

03:09:32.040 --> 03:09:48.040
Oh god, sorry for the shake. The short between the ground pin and the AC pins.

03:09:48.040 --> 03:09:54.040
Which is really bad.

03:09:54.040 --> 03:09:57.040
Wow.

03:09:57.040 --> 03:10:03.040
Okay.

03:10:03.040 --> 03:10:16.040
I'm fairly sure that my chassis ground, which is the case, is going to be connected to earth here.

03:10:16.040 --> 03:10:21.040
Oh no, I guess not.

03:10:21.040 --> 03:10:24.040
Nope.

03:10:24.040 --> 03:10:27.040
Holy moly.

03:10:27.040 --> 03:10:35.040
I didn't actually do a screw to the coarser to the power supply.

03:10:35.040 --> 03:10:40.040
Wow.

03:10:40.040 --> 03:10:43.040
Wow, wow, wow, wow, wow, wow.

03:10:43.040 --> 03:10:46.040
Okay, my sanity check is this.

03:10:46.040 --> 03:10:52.040
I have a DC power supply that is not connected to any grounds on this thing anywhere.

03:10:52.040 --> 03:10:57.040
It's plugged into the same thing as this one, the brain, the other power supply.

03:10:57.040 --> 03:11:05.040
It doesn't matter. It skips the rectifier entirely, so the entire AC part of the system effectively doesn't exist.

03:11:05.040 --> 03:11:15.040
What I get to check now is without weird ground loop shenanigans if the current is still flowing.

03:11:15.040 --> 03:11:18.040
So using this supply, I can current limit it.

03:11:18.040 --> 03:11:26.040
I should expect to see a very large increase in the current right away as the capacitors are all charged up.

03:11:26.040 --> 03:11:32.040
And then once that's done, it should level off.

03:11:32.040 --> 03:11:36.040
So let's turn it on.

03:11:36.040 --> 03:11:45.040
Okay, 250 milliamps form.

03:11:45.040 --> 03:11:58.040
So I have one amp, something is not correct here.

03:11:58.040 --> 03:12:10.040
Something is not behaving. That one amp should drop down very fast.

03:12:10.040 --> 03:12:13.040
See if anything is getting noticeably warm.

03:12:13.040 --> 03:12:16.040
It does not appear that way.

03:12:16.040 --> 03:12:25.040
Okay, next guess. I'm going to unplug this, disconnect a couple of the capacitors.

03:12:25.040 --> 03:12:30.040
As long as I only touch one side, I don't have to worry about anything in particular.

03:12:30.040 --> 03:12:33.040
I'm also going to just avoid touching the chassis.

03:12:33.040 --> 03:12:38.040
Okay, this probably means it's not the very AC that's causing me the problem.

03:12:38.040 --> 03:12:43.040
Hooray! More troubleshooting is fun.

03:12:43.040 --> 03:12:47.040
I'm going to time-lapse this because it's not going to be the most thrilling thing on the planet.

03:12:47.040 --> 03:12:52.040
I apologize for the wobbliness. I believe I have figured out the problem.

03:12:52.040 --> 03:12:56.040
So I have this white and black wire.

03:12:56.040 --> 03:13:04.040
Black is hot, white is neutral, or yeah, in this case positive and zero because it's DC, but whatever.

03:13:04.040 --> 03:13:07.040
I think I got them backwards.

03:13:07.040 --> 03:13:16.040
So I was essentially just dumping whatever my voltage was across the two diodes in each of these because I had them in parallel.

03:13:16.040 --> 03:13:19.040
So I have flipped the things.

03:13:19.040 --> 03:13:24.040
I've disconnected the capacitors just because I don't want to deal with them.

03:13:24.040 --> 03:13:27.040
I still have this small tap so there still will be a little bit of inrush current.

03:13:27.040 --> 03:13:37.040
But oh for my sanity, I had it wired right earlier and I think I had it wired right.

03:13:37.040 --> 03:13:41.040
And oh for my sanity, I believe I had it wired right earlier.

03:13:41.040 --> 03:13:47.040
Well, I know I had it wired right earlier because it was working at one point before I put it in this freaking box.

03:13:47.040 --> 03:13:55.040
So I somehow pulled a big, a big dumb, dumb brain move and inverted it for some Godforsaken reason.

03:13:55.040 --> 03:14:02.040
The way I'm going to check. Again, using the DC power supply just to remove variables.

03:14:02.040 --> 03:14:10.040
Again, this should be a brief peak of current going in so it should go up for a bit as I'm increasing the voltage.

03:14:10.040 --> 03:14:14.040
And then it should decrease down a ton.

03:14:14.040 --> 03:14:20.040
Just turn that current limit to zero and let's go.

03:14:20.040 --> 03:14:25.040
Hey, I had the wires backwards.

03:14:25.040 --> 03:14:29.040
Damn it. On the bright side, very easy problem to fix.

03:14:29.040 --> 03:14:32.040
On the not as bright side, I feel like a big dumb dumb.

03:14:32.040 --> 03:14:39.040
So I'm going to attach a whole bunch of stuff together, get everything reassembled, and I'll see you back in a bit.

03:14:40.040 --> 03:14:50.040
After that glorious massive troubleshooting, I will take one thing back that I said earlier.

03:14:50.040 --> 03:14:55.040
The variac ground connected to neutral probably didn't cause my problem.

03:14:55.040 --> 03:15:01.040
That being said, still not a good idea.

03:15:01.040 --> 03:15:04.040
I know this in theory has no, it has no isolation.

03:15:04.040 --> 03:15:12.040
What am I talking about? It has no isolation. The ground of this should not be connected to neutral.

03:15:12.040 --> 03:15:16.040
Just kind of period. That's not a good idea.

03:15:16.040 --> 03:15:19.040
Period.

03:15:19.040 --> 03:15:25.040
Because lots of reasons. I will be addressing that and this will not be involved in the circuit in the long run.

03:15:25.040 --> 03:15:31.040
And now I will have just be more aware that this chassis might get energized if...

03:15:31.040 --> 03:15:35.040
Well, yeah, it could. It could get energized, which is just not so good.

03:15:35.040 --> 03:15:42.040
Anyway, back at running this beast.

03:15:42.040 --> 03:15:47.040
That was an interesting sound. That was hopefully something falling off the table.

03:15:47.040 --> 03:15:50.040
Okay, doke skiddle-y-okly.

03:15:50.040 --> 03:16:03.040
So this should now just work without all of this extra mucking about and being terrified of the fact that apparently there's a huge amount of current falling.

03:16:04.040 --> 03:16:07.040
Duh, brain please.

03:16:07.040 --> 03:16:20.040
I'm also like embarrassed and kind of laughing at myself that I got the polarity on the IGPT's wrong, but what can you do?

03:16:20.040 --> 03:16:27.040
Alright, I'm again probing the DC side because I have this probe on the AC side.

03:16:27.040 --> 03:16:36.040
I hooked up the capacitors again. I also hooked up the coupling toroid that would go to the work coil, but it's over here because I just...

03:16:36.040 --> 03:16:41.040
One thing at a time. Turn the variac all the way down.

03:16:41.040 --> 03:16:44.040
Switch it on. Cool.

03:16:44.040 --> 03:16:50.040
That's looking good. And this is charging very slowly, which is nice.

03:16:50.040 --> 03:16:53.040
Okay, so let's start powering up a bit.

03:16:53.040 --> 03:16:56.040
Okay, that's good.

03:16:57.040 --> 03:17:00.040
Switching ranges. There's a fly.

03:17:00.040 --> 03:17:04.040
If it lands in the wrong spot, it's going to get poofed.

03:17:06.040 --> 03:17:08.040
Okay, 23.

03:17:10.040 --> 03:17:12.040
Just in case.

03:17:17.040 --> 03:17:21.040
Okay, this is on now.

03:17:21.040 --> 03:17:25.040
And we are drawing.

03:17:25.040 --> 03:17:29.040
0.02 amps according to this.

03:17:29.040 --> 03:17:33.040
So zero ampere, zero current essentially.

03:17:33.040 --> 03:17:37.040
Obviously there's some because there's losses.

03:17:50.040 --> 03:17:53.040
Still essentially zero current draw.

03:17:55.040 --> 03:17:59.040
I'm not touching the chassis just because I don't want to mess with that.

03:17:59.040 --> 03:18:05.040
68, 70, 80 volts.

03:18:05.040 --> 03:18:09.040
Still drawing about zero.

03:18:09.040 --> 03:18:14.040
So this is 59 volts. Yeah, that roughly checks out.

03:18:18.040 --> 03:18:24.040
So when I turn this dial up, the current does go up a decent amount as it charges up the capacitors,

03:18:24.040 --> 03:18:27.040
but because there's essentially nothing that's draining them,

03:18:27.040 --> 03:18:30.040
the current drops down really, really fast.

03:18:30.040 --> 03:18:36.040
If I removed the drain resistor, this current would probably be so low that it wouldn't be able to measure anything.

03:18:36.040 --> 03:18:41.040
But I just want to get up to 120.

03:18:41.040 --> 03:18:44.040
AC, not 120 DC.

03:18:49.040 --> 03:18:52.040
90 volts, AC.

03:18:54.040 --> 03:18:57.040
100 volts, AC.

03:18:57.040 --> 03:19:00.040
So far, so good.

03:19:03.040 --> 03:19:06.040
110.

03:19:06.040 --> 03:19:12.040
And we're at outlet-ish, ish.

03:19:12.040 --> 03:19:15.040
So you can see outlets giving me about 170 rectified.

03:19:15.040 --> 03:19:21.040
That's just because of the peak-to-peak and shenanigans for transferring between them.

03:19:21.040 --> 03:19:24.040
Just as one more sanity check here.

03:19:24.040 --> 03:19:28.040
Again, I don't want to just touch the chassis.

03:19:28.040 --> 03:19:32.040
Okay, the same voltage is also across the capacitors.

03:19:32.040 --> 03:19:41.040
Yay, things are working. Okay, so let's power this down and turn it off.

03:19:41.040 --> 03:19:49.040
The voltage is not going to drop very quickly, as I have mentioned several times before.

03:19:49.040 --> 03:19:54.040
160 volts!

03:19:54.040 --> 03:19:58.040
And this is going to take minutes to discharge.

03:19:58.040 --> 03:20:02.040
But that's awesome. It worked.

03:20:02.040 --> 03:20:09.040
Which means this whole setup is good, so I'm going to get the power meter mounted at the front so I can read it while I'm using it.

03:20:09.040 --> 03:20:12.040
Time to once again release the ducts.

03:20:20.040 --> 03:20:28.040
Don't mind the jank. There's a bolt stud in the way on the other side, so I have to go from the bottom.

03:20:28.040 --> 03:20:31.040
Quick media change. Sorry about that.

03:20:31.040 --> 03:20:34.040
So, variac is on.

03:20:34.040 --> 03:20:37.040
Power meter.

03:20:37.040 --> 03:20:43.040
Oh god, it's so difficult to read.

03:20:43.040 --> 03:20:46.040
Currently drawing .2 amps.

03:20:46.040 --> 03:20:50.040
2 volts AC, just because.

03:20:50.040 --> 03:20:55.040
So, let's see if I can make it so you can see this little monstrosity.

03:20:55.040 --> 03:21:02.040
Okay, so if I turn this on, it drops the current.

03:21:02.040 --> 03:21:05.040
It drops the voltage so low that it no longer works.

03:21:05.040 --> 03:21:08.040
That's awesome.

03:21:08.040 --> 03:21:13.040
That's just absolutely fantastic.

03:21:13.040 --> 03:21:16.040
Let's go a little higher then.

03:21:16.040 --> 03:21:24.040
On the right side, I didn't hear any vibration in this.

03:21:24.040 --> 03:21:27.040
So that's good.

03:21:27.040 --> 03:21:30.040
Okay, 44 volts now.

03:21:30.040 --> 03:21:33.040
Let's try that again.

03:21:33.040 --> 03:21:39.040
So...

03:21:39.040 --> 03:21:43.040
That's drawing a fat 60 amps at no load.

03:21:43.040 --> 03:21:47.040
However, there's something very interesting here.

03:21:47.040 --> 03:21:50.040
Watch the power factor.

03:21:50.040 --> 03:21:57.040
It's skyrocketing, and the actual wattage is reading at zero.

03:21:57.040 --> 03:22:03.040
So what that means is essentially all of the power that's getting brought in

03:22:03.040 --> 03:22:08.040
is getting dumped back in, and it's almost entirely reactive power,

03:22:08.040 --> 03:22:14.040
although I don't trust that wattage measurement in the slightest.

03:22:14.040 --> 03:22:21.040
So, you know, whatever.

03:22:21.040 --> 03:22:27.040
Okay, now let's do some heating testing.

03:22:27.040 --> 03:22:29.040
So I have a nice par.

03:22:30.040 --> 03:22:40.040
It shouldn't get hot, but I'd rather be careful.

03:22:40.040 --> 03:22:47.040
So it was drawing 6 amps at about 36 volts DC, which is a lot.

03:22:47.040 --> 03:22:51.040
Okay, so it's on.

03:22:51.040 --> 03:22:55.040
As I'm loading it, the current is dropping.

03:22:55.040 --> 03:22:58.040
Okay, you can't see a damn thing there.

03:22:58.040 --> 03:23:05.040
So the power factor centers a little as I load it,

03:23:05.040 --> 03:23:17.040
and the current drops like a stone to like 2 amps.

03:23:17.040 --> 03:23:23.040
You can actually, hopefully, but probably can't see how much it changes

03:23:23.040 --> 03:23:26.040
as I move this further in and out.

03:23:26.040 --> 03:23:30.040
So it loads the work coil more or less.

03:23:30.040 --> 03:23:34.040
That's pretty warm.

03:23:39.040 --> 03:23:43.040
That's probably okay.

03:23:43.040 --> 03:23:51.040
No, okay. Let's try.

03:23:51.040 --> 03:23:55.040
Up to like 60.

03:23:55.040 --> 03:24:04.040
I'm going to preload the work coil so I don't send the current into the actual stratosphere.

03:24:04.040 --> 03:24:09.040
So that's still drawing 5 amps.

03:24:09.040 --> 03:24:15.040
I hear a little bit of vibration out of the transformer now.

03:24:15.040 --> 03:24:19.040
The paper is starting to smoke on this.

03:24:31.040 --> 03:24:40.040
I'm actually just going to turn that off. I'm not sure what's burning off there, but clearly getting very hot and very fast.

03:24:45.040 --> 03:25:08.040
Okay.

03:25:08.040 --> 03:25:12.040
Switching to a slightly different bar steel just because

03:25:12.040 --> 03:25:16.040
this shouldn't have any like random goodies on it.

03:25:16.040 --> 03:25:19.040
Hopefully, we'll see.

03:25:19.040 --> 03:25:26.040
Okay, let's do that again.

03:25:26.040 --> 03:25:32.040
All right, so it's drawing about 3. something amps.

03:25:32.040 --> 03:25:37.040
And it will go up to...

03:25:37.040 --> 03:25:42.040
It actually goes down again. So it's still only at about 5 amps. That's pretty good.

03:25:53.040 --> 03:25:59.040
Okay. I'm going to turn up the power a bit.

03:25:59.040 --> 03:26:02.040
It's warm. It's warm.

03:26:08.040 --> 03:26:13.040
It's really 85.

03:26:13.040 --> 03:26:17.040
Yeah.

03:26:17.040 --> 03:26:24.040
83.

03:26:24.040 --> 03:26:29.040
You probably can't see the power meter at all, which I don't really like because that's kind of the whole fun.

03:26:29.040 --> 03:26:32.040
That's the whole fun part.

03:26:32.040 --> 03:26:36.040
So I'm going to do a little shimmy shimmy.

03:26:36.040 --> 03:26:40.040
I'm trying to bring you down to the height where you can see it.

03:26:40.040 --> 03:26:43.040
Oh my god, he's going to die again.

03:26:43.040 --> 03:26:47.040
So you're tuning.

03:26:47.040 --> 03:26:50.040
Oh, man, that backlight is awful. Holy moly.

03:26:50.040 --> 03:26:53.040
Okay, so let's loosen this.

03:26:53.040 --> 03:26:57.040
Correct.

03:26:57.040 --> 03:27:03.040
Okay. And then I'm going to turn up the power meter.

03:27:03.040 --> 03:27:07.040
And then I'm going to turn up the power meter.

03:27:07.040 --> 03:27:11.040
And then I'm going to turn up the power meter.

03:27:11.040 --> 03:27:15.040
And then I'm going to turn up the power meter.

03:27:15.040 --> 03:27:19.040
Okay. And then I want to plug this in.

03:27:19.040 --> 03:27:26.040
That would be kind of funny if it died right as the fun stuff happened.

03:27:26.040 --> 03:27:30.040
As the fun stuff is going to happen soon.

03:27:30.040 --> 03:27:33.040
Hopefully.

03:27:39.040 --> 03:27:42.040
Okay.

03:27:43.040 --> 03:27:49.040
So this needs to get plugged in.

03:27:58.040 --> 03:28:01.040
All right.

03:28:01.040 --> 03:28:11.040
So let us hit it with 83 volts to see that is quite one.

03:28:11.040 --> 03:28:15.040
So the bar is already toasty.

03:28:15.040 --> 03:28:18.040
I'm going to again preload the coil.

03:28:18.040 --> 03:28:22.040
I need more room.

03:28:22.040 --> 03:28:28.040
I don't want to be fighting anything here. Okay, so preload the coil.

03:28:28.040 --> 03:28:32.040
Turn it on. How much current am I getting? Four amps.

03:28:32.040 --> 03:28:35.040
Okay.

03:28:35.040 --> 03:28:40.040
Up to five. Up to eight.

03:28:40.040 --> 03:28:43.040
Okay, that's getting high.

03:28:48.040 --> 03:28:52.040
It is starting to smell warm.

03:28:58.040 --> 03:29:01.040
Decrease the load a little.

03:29:02.040 --> 03:29:07.040
Yeah, something is a smoking.

03:29:07.040 --> 03:29:13.040
I made a slight modification to one particular component.

03:29:13.040 --> 03:29:22.040
Being the bar steel. I got rid of all of the mill scale on the part that's going to go into the coil.

03:29:22.040 --> 03:29:25.040
Just so we have an easier time seeing what's going on.

03:29:25.040 --> 03:29:30.040
And there's less likelihood of random stuff starting to smoke.

03:29:30.040 --> 03:29:37.040
Okay. So I am looking at very low draw.

03:29:37.040 --> 03:29:41.040
And let's hit it.

03:29:45.040 --> 03:29:48.040
So four amps at 80 volts.

03:29:48.040 --> 03:29:54.040
I mean, it's fairly stable. It's not as high as I would like.

03:29:55.040 --> 03:29:58.040
Steel is definitely getting warm.

03:30:01.040 --> 03:30:04.040
I'm also slightly confused why you aren't charging.

03:30:11.040 --> 03:30:13.040
Oh.

03:30:15.040 --> 03:30:19.040
Okay, sure. Alright, turn it up.

03:30:20.040 --> 03:30:23.040
90 volts.

03:30:23.040 --> 03:30:26.040
100 volts.

03:30:26.040 --> 03:30:29.040
Again, I'm going to preload the coil.

03:30:29.040 --> 03:30:32.040
Hopefully not trip a breaker.

03:30:32.040 --> 03:30:35.040
Okay, preloading coil.

03:30:35.040 --> 03:30:39.040
And turn off this backlight because it's hot poo poo poo poo.

03:30:39.040 --> 03:30:44.040
On we go. I'm looking at five amps at 94 volts.

03:30:44.040 --> 03:30:47.040
So this is dumping about 500 watts into the system.

03:30:50.040 --> 03:30:53.040
What'll it go up to?

03:30:53.040 --> 03:30:57.040
Six amps, seven amps, eight amps, nine amps.

03:30:57.040 --> 03:31:02.040
If I reload the coil. Oh, okay, I can see the coil starting to discolor.

03:31:04.040 --> 03:31:07.040
Okay, this is going to be a little bit of a load test.

03:31:10.040 --> 03:31:14.040
So it peaks at eight amps at 100 volts.

03:31:15.040 --> 03:31:19.040
That's a lot lower than I expected to be perfectly honest,

03:31:19.040 --> 03:31:25.040
but hey, it's starting to get black. Alright, well, I'm going to turn this off and come back quickly.

03:31:27.040 --> 03:31:32.040
Or am I? Oh, that coloration though.

03:31:32.040 --> 03:31:37.040
Look at that. It's doing the thing.

03:31:37.040 --> 03:31:41.040
Probably getting very close to getting red hot.

03:31:44.040 --> 03:31:48.040
Current draws actually going down. Oh, it's getting really close to glowing.

03:31:48.040 --> 03:31:51.040
Coloring though. Oh, it's so pretty.

03:31:51.040 --> 03:31:56.040
Come on, you can do it. Just give me a little bit more.

03:31:58.040 --> 03:32:02.040
Okay, I'm going to call it there. Whoa, it's hot.

03:32:02.040 --> 03:32:05.040
This, this, this hot.

03:32:05.040 --> 03:32:09.040
This hot, hot, hot, hot, hot. Eight amps at 100 volts.

03:32:09.040 --> 03:32:13.040
I shouldn't blow the breaker at 120.

03:32:13.040 --> 03:32:17.040
Okay, don't mind the million dollar server sound in the background.

03:32:17.040 --> 03:32:24.040
On it goes. 11 amps unloaded because whoops, but seven amps loaded up.

03:32:24.040 --> 03:32:29.040
So this is dumping about 7800 watts into this bar.

03:32:29.040 --> 03:32:35.040
The voltage drop because of the voltage drop across the variac,

03:32:35.040 --> 03:32:39.040
which I just realized I should probably look at and make sure isn't melting.

03:32:39.040 --> 03:32:45.040
Okay, it's discoloring already. 1000 watts.

03:32:45.040 --> 03:32:48.040
It's dropping back down.

03:32:48.040 --> 03:32:54.040
700 watts. Getting that nice blue, almost white coloration on the steel.

03:32:54.040 --> 03:33:00.040
Eight amps. So I don't expect this to melt it, melt the bar.

03:33:00.040 --> 03:33:03.040
It might get it red hot. I honestly don't know.

03:33:03.040 --> 03:33:07.040
If I was using a smaller bar of steel, it would probably stand a better chance.

03:33:07.040 --> 03:33:14.040
Yeah, buddy. Don't know if you can see that nice, nice red glow.

03:33:14.040 --> 03:33:17.040
Oh yeah, you can. Yeah, buddy.

03:33:17.040 --> 03:33:23.040
That is some red hot steel from an induction heater on a wall outlet level of power.

03:33:23.040 --> 03:33:28.040
Woo! Sorry for rip headphone users all that.

03:33:28.040 --> 03:33:31.040
It's red hot. It did the thing.

03:33:31.040 --> 03:33:38.040
Holy crap. I mean, it took a hot minute, but like, oh my God, it did the thing.

03:33:39.040 --> 03:33:43.040
Woohoo! That's like legitimately very exciting.

03:33:43.040 --> 03:33:46.040
I can feel the heat from here.

03:33:46.040 --> 03:33:49.040
Like it's uncomfortably warm from here.

03:33:49.040 --> 03:33:56.040
Yeah, buddy. So I was just poking around things in here just to give a little checky check.

03:33:56.040 --> 03:34:01.040
This thing has no battery because of course it doesn't.

03:34:01.040 --> 03:34:04.040
Well, that's fun. Whatever. This worked all right.

03:34:04.040 --> 03:34:09.040
It's freaking hot. And a little bit warm.

03:34:12.040 --> 03:34:16.040
Holy moly. What a mess.

03:34:16.040 --> 03:34:20.040
I have made. Hit it harder.

03:34:20.040 --> 03:34:24.040
Yeah. Yeah, it worked. Holy crap.

03:34:24.040 --> 03:34:29.040
Also, I realized I think this is designed for thinner metal, but too late now.

03:34:31.040 --> 03:34:35.040
So back at you with some other cool stuff that I learned during this project.

03:34:35.040 --> 03:34:39.040
This is the other piece of the top of the case for the induction heater,

03:34:39.040 --> 03:34:42.040
and this is steel that has been powder coated.

03:34:42.040 --> 03:34:46.040
Powder coat is something that I'm not completely familiar with,

03:34:46.040 --> 03:34:49.040
but essentially you take a really high voltage sprayer,

03:34:49.040 --> 03:34:53.040
you hang whatever you're trying to coat on something that's negative,

03:34:53.040 --> 03:35:01.040
and then you go and it sticks to it and cures and is a very tough, very robust coating.

03:35:01.040 --> 03:35:06.040
Another fun thing about powder coat is you can etch it away with a laser.

03:35:06.040 --> 03:35:13.040
So this is a Lichtenberg pattern that is not made using hilariously dangerous methods

03:35:13.040 --> 03:35:17.040
and wood burning and stuff. Don't do that, please.

03:35:17.040 --> 03:35:21.040
But I'm quite happy with how it turned out,

03:35:21.040 --> 03:35:29.040
so I'm going to slap a really big one on the outside of the top of the case,

03:35:29.040 --> 03:35:33.040
because I can, and why not? It'll be fun.

03:35:45.040 --> 03:35:53.040
And with that, I pretty much have the induction heater part of this project more or less done.

03:35:53.040 --> 03:35:58.040
We're going to give this a little bit of a touch up with some Scotch Brite or something like that

03:35:58.040 --> 03:36:04.040
and give it a light coating of whey oil as well just to prevent any further oxidation.

03:36:04.040 --> 03:36:07.040
But I'm quite happy with how it turned out.

03:36:07.040 --> 03:36:16.040
Probably could have used a little bit more contrast, but looks pretty sick.

03:36:16.040 --> 03:36:18.040
Heck yeah, but...

03:36:20.040 --> 03:36:23.040
In my last endeavor of testing this system out,

03:36:23.040 --> 03:36:30.040
I learned that this going through there and not being able to open this up is a gigantic pain.

03:36:30.040 --> 03:36:35.040
So I'm planning on chopping off some metal on both sides of this

03:36:35.040 --> 03:36:41.040
and also I'll recut this front piece to have it extend all the way up on both sides

03:36:41.040 --> 03:36:46.040
and then have a top piece that bolts on that will fit there permanently.

03:36:46.040 --> 03:36:49.040
I'll probably do a couple of heat set inserts into the back acrylic piece

03:36:49.040 --> 03:36:54.040
so it's held in place when the system's running so it can't accidentally fall open.

03:36:54.040 --> 03:36:58.040
But that'll just eliminate my inability to open this up

03:36:58.040 --> 03:37:02.040
and access all the copper tubing and all the connections

03:37:02.040 --> 03:37:08.040
without having to take it off first before opening it, which is just awful in every way.

03:37:08.040 --> 03:37:13.040
So we'll have a mighty fun time with that today.

03:37:13.040 --> 03:37:18.040
More of the duct machine as well, which is one of my new favorite tools.

03:37:19.040 --> 03:37:32.040
I did some things, including but not limited to the chop,

03:37:32.040 --> 03:37:36.040
which you may or may not have seen in a time lapse because it probably wasn't very interesting.

03:37:36.040 --> 03:37:40.040
I also did a little bit more design because I needed to replace this piece of acrylic

03:37:40.040 --> 03:37:46.040
with another more different piece of acrylic and another more different piece of acrylic.

03:37:46.040 --> 03:37:52.040
I then cut out said other piece of acrylic and other more different piece of acrylic.

03:37:52.040 --> 03:37:55.040
I then put some heat press inserts into it.

03:37:55.040 --> 03:37:58.040
That was an adventure.

03:37:58.040 --> 03:38:02.040
Yeah, just it was an adventure, but it's done.

03:38:02.040 --> 03:38:05.040
So that's good. This one, I don't have to do anything to.

03:38:05.040 --> 03:38:09.040
I'll just put some bolts through these to hold this on

03:38:09.040 --> 03:38:12.040
and make this relatively rigid when it's mounted.

03:38:12.040 --> 03:38:17.040
And I went to put it on. Okay, sweet, sweet.

03:38:17.040 --> 03:38:21.040
Actually, I just realized another problem live, but that's that's for later.

03:38:21.040 --> 03:38:25.040
First problem, I had this nice to line up.

03:38:25.040 --> 03:38:34.040
However, it does not fit because these two bolts are interfering.

03:38:34.040 --> 03:38:37.040
The other thing I just found out live is these heat press inserts.

03:38:37.040 --> 03:38:44.040
I didn't get them all the way in. I'm going to have to do that because with the side that they are on,

03:38:44.040 --> 03:38:47.040
they are sitting against the steel.

03:38:47.040 --> 03:38:51.040
So they have to be flush or past flush.

03:38:51.040 --> 03:38:54.040
So two things to fix.

03:38:54.040 --> 03:38:57.040
Well, to the whoops bud.

03:38:57.040 --> 03:39:01.040
So two things to fix now.

03:39:01.040 --> 03:39:05.040
Gonna have to cut out a little bit of extra steel here and here.

03:39:05.040 --> 03:39:13.040
I'll do that with the duck saw that I'm now calling it because it's awesome.

03:39:13.040 --> 03:39:17.040
And the other thing I'm going to have to do is press these inserts in.

03:39:17.040 --> 03:39:24.040
And the other thing I'm going to have to do is press these inserts in further

03:39:24.040 --> 03:39:31.040
until at least flush or past flush and remove any material that's proud of this flat plane.

03:39:31.040 --> 03:39:38.040
So that'll fit tight against there and I can tighten this down onto it.

03:39:38.040 --> 03:39:41.040
So this will be fun.

03:39:41.040 --> 03:39:48.040
Yes, I'm just going to do it.

03:39:48.040 --> 03:39:52.040
Actually, I should measure the surface because rain.

03:39:52.040 --> 03:39:57.040
Sometimes I have one.

03:39:57.040 --> 03:40:03.040
But only sometimes do I have a brain.

03:40:03.040 --> 03:40:08.040
For example, right now I don't really have a brain.

03:40:08.040 --> 03:40:11.040
Okay, that's good.

03:40:11.040 --> 03:40:18.040
That's a mark and that's a mark.

03:40:18.040 --> 03:40:23.040
RIP headphone users for this entire bill.

03:40:24.040 --> 03:40:29.040
Now time for the other adventure, which I will actually show you this time because

03:40:29.040 --> 03:40:33.040
yeah, why not? It's fine.

03:40:33.040 --> 03:40:39.040
Come join me for the fun. I have the saugering iron cranked up to a bajillion degrees.

03:40:39.040 --> 03:40:42.040
And then I just shove it into the acrylic.

03:40:42.040 --> 03:40:52.040
That's it. And then sit and wait for literally like eons.

03:40:52.040 --> 03:40:55.040
I feel like it doesn't really like melting.

03:40:55.040 --> 03:41:00.040
Also, I'm very intentionally avoiding the fumes because I can almost guarantee they're not good.

03:41:00.040 --> 03:41:07.040
I will save you the pain and only fill the first one because it takes a minute.

03:41:07.040 --> 03:41:14.040
My assumptions as to why it's taking a hot fricking minute is a fewfold.

03:41:14.040 --> 03:41:18.040
One, this is a chongest thick piece of acrylic.

03:41:18.040 --> 03:41:24.040
Two, the tip I'm using is definitely not sized properly for this particular endeavor.

03:41:24.040 --> 03:41:30.040
I'm mostly just interfacing with the cover, which is not quite as good at conducting heat

03:41:30.040 --> 03:41:33.040
from the actual heating element.

03:41:33.040 --> 03:41:37.040
And third, this is just not smart.

03:41:37.040 --> 03:41:40.040
The acrylic seems to be pretty good at wicking heat.

03:41:40.040 --> 03:41:46.040
So it's bouncing back, so that's fun. So I have to actually go well below flash.

03:41:46.040 --> 03:41:49.040
That's actually pretty close to okay.

03:41:49.040 --> 03:41:55.040
That's probably fine. Now I will not make you watch the rest of this.

03:41:55.040 --> 03:42:00.040
It's mounted properly now. I have some nice, the heatset inserts mounted.

03:42:00.040 --> 03:42:06.040
I have this mounted to here. I want to get something a little more sturdy on this side.

03:42:06.040 --> 03:42:11.040
It's currently, it's a little floppy without this part on, but when this is on,

03:42:11.040 --> 03:42:14.040
A plus is good enough for me.

03:42:14.040 --> 03:42:19.040
That's probably going to be almost all I do for this build,

03:42:19.040 --> 03:42:22.040
until the actual upgrade with Linus.

03:42:22.040 --> 03:42:27.040
I'm going to take a whole bunch of stuff out, and then reassemble it with Linus,

03:42:27.040 --> 03:42:30.040
which you will have probably already seen,

03:42:30.040 --> 03:42:33.040
because Floatplane shenanigans.

03:42:33.040 --> 03:42:38.040
But thanks for coming along on this hilarious ride with me.

03:42:38.040 --> 03:42:45.040
I suspect there will probably be a little bit of post shots of the system fully going,

03:42:45.040 --> 03:42:48.040
and heating steel up properly,

03:42:48.040 --> 03:42:52.040
and then hitting some stuff with a hammer and deforming it.

03:42:52.040 --> 03:42:56.040
A plus would do again. This was a very fun project.

03:42:56.040 --> 03:43:02.040
Thanks Intel, and thanks Floatplane for watching and having a jolly good time.

03:43:02.040 --> 03:43:07.040
Welcome to the gong show that is me having money and time to do things.

03:43:07.040 --> 03:43:08.040
It's great.
