I can in theory wait longer yeah, it's just like it yeah, we need it like yesterday
And I was planning to get it ready for Friday, but apparently we need to test this thing before Friday
And I kind of don't want to test it
Everything is fine. Yeah, nothing's broken. We're trained professionals. We're just trying to call the computer with
This thing so what exactly is happening here? Oh, you want to see?
Okay, let me show you so this is what I've been planning for the last a little bit. This is the fan
This is a 3d printed shroud. We're just about to get
This box that I didn't bother modeling very well, that's a Corsair 5000 X case
So you're gonna mount we're gonna mount a big ass fan that big ass fan
we're gonna put a shroud between the fan and computer and
And we're about to make This computer like go to non here
22.8,000 CFM So for context the highest airflow PC that we had that literally blew the top of the case off was about 4,000
So this is five times. Yeah, it's basically five times
So yeah, this is meant for like a big ass RC thing. Yeah, this has
58 kilograms of thrust two of them you can lift yourself up off the ground if you weigh less than a hundred and yeah
Seven kgs. What's that in pounds? I don't know what that is in freedom units
There you go. Someone has worked in freedom units the whole life
Yeah, that's what we're doing Alex and I discussed at length how we're gonna power this thing, okay?
The amount of power needed to make this thing spin 60 horsepower
Okay, to put that in perspective, that's half the power of my car
So legitimately this was the discussion, okay?
number one Buy a whole bunch of lipo batteries and put them in series
uh-huh, or buy a volt battery like from a car
cut it in half figuratively, but just like remove a bunch of cells until we got the right voltage because a volt battery can provide like
600 amp of current from its cell pack So we just we remove a whole bunch of cells until we get the hundred volts needed to power this thing and we literally have a car
Battery sitting here. It'll be about this big
That that need to be water cooled by the way because the volt battery is water cooled
Because it's one of the best batteries ever made and that would power this thing
We ended up going with lipo batteries because it was slightly cheaper at like
foreground Yeah, something like that
now You might be wondering why did we not connect it to the wall from the wall a
Normal North American circuit is 1.8 kilowatts if you use like a 240 volt
That's what like 3.4 kilowatts this thing draws 45 kilowatts
It's not even close you cannot plug it into the wall it will draw too much current by a lot. Yep. We're about to go to the red line
See
These are the batteries that we got to power it, okay
So this is Alex's first time seen it
That is a really nice battery. Oh, bro
Yes, they also like they're also cost a hundred and sixty nine dollars each and we got 15 of them
So this is a 4s lipo battery. So that means there's four
cells in series It's rated for 130 C
So what that means for people that don't do cars this capacity is 6,000 milliamps in other words six amp hours, okay?
But you in theory can discharge it at
130 times its capacity so in theory you could draw over 600 amps
From this battery and it still be fine in theory. We're not going to do that
We're only gonna go do about 260 maybe 270 not much beyond that
But this is only 4s. We need 24 s to power this
Okay, so if you're good at math, you know where I'm going. Well, what's 4s?
Plus another 4s plus another 4s plus another 4s six times you get 24 s
So we're gonna put six of these in series
Then for out of good measure, we're gonna build another six series and
Stick it on top and put those two in parallel
For extra capacity because at Phil tilt we will drain this battery in three minutes
So that's some behind-the-scenes that may or may not make it into the final cut, but that's how much thinking went into this
Let's just say we're gonna test this before getting Linus in here because we're actually nervous
That we're gonna blow the tempered glass out the sides. Yeah, that is a bit might just remove the side panels
No, we're doing that on camera. We need to try that. Okay. Well, then we need to build like a freaking like plexiglass structure
Yeah, this can 100% this is a rat RAM. This is behind-the-scenes rambling
We do need to start a roll though, okay How should we say this in a way that makes sense instead of just rambling to the social team for a while?
That's a good question good thing. We have a right again. Yeah
Yeah, I guess that's my problem Do we want to like intro the fan?
We'll intro the fan in the intro. Okay in the intro. This is this is just post-intro. This is post-intro
So this is kind of when we're like we've got the fan
It's really scary And we need to make sure that we don't blow ourselves up. Okay
How we're going to do that is by using this thing which on its own
Not too bad This thing is actually pretty scary once again
Well, we do need to tell the story of how we came we need to tell the battery the battery story because that was a significant pull
I actually power it. I think that we have Linus do that on Friday in a roll. Okay, that's that's fine
Okay, so you script that I'm gonna have the crate. We're gonna have the hook. You're gonna the intro
Then we want to what cut to us building the actual battery
Or do you want to cut to Linus explaining the choice of making the battery?
So I guess are we we're not making the battery today. That's a give you oh, we are yeah, okay
That's why I have a little stuff. Yeah, we can we were testing and making the battery
I thought we were just testing Do you want Linus to make to try to make the battery? No, not really
The main things that we want to do today on camera is show this being a
Sketchy solution, but a lot less sketchy just to just to test it. Yeah, it's a lot less sketchy than having
200 500 amps available to us and we like take this apart. Yeah, good. Look. Yeah. Do you want to start by doing that?
This is the AC is gonna power it. It's a complex piece of electronic thing. We're gonna take it but
Sure Legally, you're not allowed to use this for human flight, but people have
Oh All right, there's legal in what you yeah, and camera is rolling
Bassie fan VF 390 day one
This is going multiple days, you know that I
Guess do we have anything else to say really? I mean the only thing I have to say is
This is the ESC That's the fan and this
It feels like it's like
Tidy-ass little thing powering just death
Roland we have these big capacitors here
to talk about There's this IC
Keep the fun You've got our PWM lead
Okay
PWM lead we've got our firmware controller, whatever settings leave
This is very similar technology to what's in an EV car that takes power from the battery and
Converts it to what the motor needs to go forward except we're gonna thank in the middle of the cut
Hmm
That takes power from the battery and converts it to the three-phase unit to run the induction motor for the car
Instead of making the cargo for we're gonna attach to a fan and
Yeah, make our computer go backwards maybe
Yes, is that b-roll ready that is
I
Know Could have made a really awkward joke there, but decided against it
Do you have any more of these guys? No, no that one came with the ESC. Oh, I have a whole bunch of five millimeter ones
Doesn't go in. Yeah, five doesn't go into eight. Hmm
Quick math You could do
Just take some more eight gauge wire. This is all the eight gauge wire
Like that that's all the eight gauge wire. Yeah, that expensive me
Like this. So this was like this was like 60 bucks
That was 60 bucks. Yeah from Digikey I could have ordered a cheaper from somewhere else, but there was a lead time issue. Oh, yeah
I should have brought some of the wire that I have. No, it's not high enough current. This is this is silicon sheathing
It can handle we only need to handle 10 amp. Oh, yeah, okay for that. Yeah, okay
We could use smaller wires and then like, oh, yeah, okay, I see the problem now. Yeah
One of my ways to be doing the game. Oh, I mean, yeah, okay
I need a snippet I need a snipsnip thing
Oh There's some flash cutters. We're gonna cut some things fleshly
Oh, that doesn't have a battery, does it? Yeah, I feel like we're gonna break this thing to taste so small
Oh
When you get the creepy things
Well, that's this kind of sketch
Uh that went somewhere. I don't know where it went. Someone's gonna find it later
And this is why the shop is dirty
Alex, yeah, it doesn't fit your bigger nuts. Oh
I mean, I could just try and force it I mean, I am gonna snip this off like a lot sooner anyway
I really should have just brought some stuff from my house
A bunch of 8-gauge and 4-gauge wires and all the connectors. 4-gauge. Yeah, this is 6-gauge. It was like
Thick boy. Yeah for what sound? Yeah
Sounds like stinger. Oh, yeah, I wouldn't it wouldn't handle the max card that we're gonna send through it wouldn't be 260
output Yeah, no, it's like CCA, which is why it means it's difficult to find like cable that can actually handle
hundreds of amps That's not like this thick and completely like stupid to work with
Find a way to click that into that thing and then we're good. I'm gonna try this. I'm gonna try and strip this
Yeah
Bye
Or like the engineering workshop is like full of like stripped off pieces of wire because I don't know why I think I think I
Subcheap, I don't bother buying like proper wires strippers. I just use
the cut and flick method
This is going this fine, and we haven't even started building the battery pack
Man this tape is like sticking to my freaking noise. I'm gonna pet. Yeah
Just sticking to my head. Do we know if there's any sort of protection on here?
I Given this was incredibly cheap and from Amazon. Okay. Oh, this is Jesus. Oh, yeah, Jesus
Well, I'm just gonna like jam the wire and then I don't know where they like it's it's very it's very like
Strandy wire so the spokes could go everywhere
You could just tend the wire
I'm gonna say that for later you'll see why when you try and turn this wire
Uh You know what we could have done we could have had a fuse on the battery pack
For the video we need to wire to the trigger. Yeah, it's like just sit there be like run the benchmark Alex
Then again, do we actually want that as an option
I
Are you commenting that we need double A's for that to work. Yeah, I didn't know that. Oh, okay. Never mind. He knew that I
Thought we're gonna get that he's gonna be like, why is it working Kyle?
That went better in my head than actually went to real life. It's okay. Do we have double is the camera done does
Thank you Creative warehouse is not the size of like the whole company when I joined. Yeah, it's oh
Crazy there are 15 people Yeah, and that was like six years. Yeah, so from six to three
You basically went from 15 to 25 because I was a 26th person. Yeah, and then from
my time to now it's like
107 Absolutely explode. Anyways, I'm sure we beat that horse or not
Yeah, that's all just gonna be a full plane. Yeah, I'm sorry to the editor. That's all not a rule. Yeah
Be prepared for explosion. I may be made up on the safety glasses
This is probably okay. Do you want to turn it off? Is it up?
Yes, you can turn it you can turn the output off. Okay, so when I read on the internet, this is supposed to be the connection method
It's fine everything's fine. Okay, so the connection method that I read up was you plug the hot side in
Okay
Then you plug this in
No spark and then we wait
Capsichide
Probably not very long that's supposed to be it. We should insulate that at some point. Yeah. Yeah
Okay, now we smell from magic smoke So if you smell a very funky smell
It's Alex See, I'm not the only person who asked this question because it's the top search thing on YouTube
How to power a fly sky receiver, which is listening
I don't do RC So I am being educated by Google
And the RC controller, that's the thing that connects to so that yeah
So basically when I when we go room room
You somehow need to tell that thing to go from room. Yeah, so because it's wireless. This is the transmitter
This is the receiver. Okay, this gets powered by the batteries that Alex just went and fetched
So this will get power but
This thing needs power and
Currently, I don't know how it gets power
So this is a six-channel receiver you can see ch1 ch2 ch3 blower all the way six
Then there's also a bind on the top right, so
My assumption is that you can bind. Well, you can bind this to different remotes by shorting out some
Terminal in here and putting them to bind mode and then you do something with a receiver and then it pairs, right?
My assumption is that if I put
Voltage on the bind just like five volts. It'll power the receiver
I just want to make sure that that's actually the case so that if I do it. It doesn't blow it up
Mainly because we don't have extra and I don't want to blow stuff up. So
We might actually have extra for that, but yeah, yeah, yeah, yeah. Oh
My god, what oh just seeing that
Yeah sneak peak there it is there we go. There we go. Ha ha
Position let's move it down I'm going to try and get like maybe two in the same frame
sideways position Two in the same frame. There we go. There's two in the same frame
All right, so from there to there is 50 times a second. All right, so from and
Then there's one hump. There's another hump and then when you change it. It'll change both of them
right so
From a DC side what that's actually doing is you're starting with five volts
But because you're only on for like what is essentially 10% of the time you actually read like 10% of the voltage out
If you if you if you just would have probed it with DC, but what the actual
ESC sees is sees that bump it reads the duty cycle and then
Changes the fan speed accordingly That's a very high-level definition of what it is
Cool Teen to change that's a roll right those two things. I don't know
Change that's very potentially just more flow plane exclusive, but a little bit of that explanation will be in for sure
Or you can just like Remove me out and have someone use a little bit more lesser verbose explain it
I don't know. I think that was a pretty good explanation. I Dig it cool
Nope Emma
Thank you
I
The back brace for the computer So it doesn't fly that way. It doesn't know where it goes. Um in theory no
Do we have a big old heat shrink? Do we have a big old heat shrink? I was gonna use electrical tape, but yeah inside the bottom drawer of the electronics cabinet
You probably don't want to be on this end when that fan is on this side
You don't necessarily want to be here, but it's much better than being on this. Yes
Because if you think about it, these pins right here are the thing that are going to kill you
So if one of these explodes, it's already loaded up so it shoots this way
So if this fan explodes everything's coming out
Like that which is a bit counterintuitive because you kind of think it would go down
But you know there might be some Yeah, majority of the big chunks are gonna go
Yeah, this blade is going to try and heat itself in that direction. Yeah, this is more of a sandy check
Yeah, and then we're gonna build a big battery
It's a big fan, hey, I Was thinking maybe this big but like holy crap. That's a big fan. Yeah, big fan
All right, wait get get like everything expensive out the freaking way
Oh
That's 10% power I
Needed that
You found more I did oh
Hello spider. Oh, no, it's a mosquito. Ah, geez that's a big sucker. You see it
Where the freaking on
There you go weapons velocity mosquito. Yep
