Look at that one. Yeah, that's right. Okay
That is just giving it away
What? Like
What? No
Um
Uh
Lama got a sequel is open source sure
Sure Open source. Oh, yeah. Okay. Okay
I'm giving away a purpose. I'm purpose this time
Yeah All right, one of those
So we're doing a video where we try and destroy a hard drive essentially and we did some I
Google search it. I was gonna say we were doing some research, but no, I literally just Google search it and found a found the answer
To destroy hard drive you need 450 pound of force like magnet pull force this fishing magnet right here
It's used to like grab stuff from the bottom of a pond or a lake or whatever
That's a 650 pounds. So in theory
This magnet should destroy any hard drive. We have a hard drive right here though. This is already
It's already destroyed You'll see it in a future tick tock and a future LTT video as well how this happened
But I'm just gonna see if like how strong it feels like when I attach it to this thing
Okay, you ready? I'm ready. Yeah. Oh
That's a snap Okay, it comes on. Yeah, you can take it off. Okay. Yeah, it's not bad
But this is definitely a strong magnet you heard that stuff, right? All right one more time one more time
Okay, do not get your fingers stuck between that because that is no no
Yes, the hard drive is completely gone now it's crushed it's degaust magnet
Oh
Can't even pull it apart
There's like you're gonna pry it off that are in weak
I mean I already got it off All right, the magnets in my shirt. Oh my god
Oh
That's insane magnets. Oh my god, what is even going on stop? What are you doing?
Don't find this obviously
Oh My god, it's wait, you're not like talking to you, right? Oh, I have my phone and it has oh, no
It has magnets in it. So watch more from my watch. Okay, my watch is fine
My phone is like the folding magnets, right? Oh careful your fingers. I know I see. Yeah
You should try it with like right with a weather shirt between it without the oh, no
I used to take apart hard drives because we used to break them apart when we were destroying clients data
So like I had a whole fridge just full of hard drive
Oh, they're so strong
Catch
So what are we doing Sean fly drone flying a drone excellent by the DJI
Maverick free that they are selling about DJI we're like like Apple they release things as soon as you buy
Yeah, well thing. Well, what happened was I was like, you know what? I'm gonna finally buy the Mavic 3 their flagship
Two months after I'd buy the DJI Mavic 3 their flagship. They come up with the DJI Mavic
I said am like, okay, that's fine. That's fine. You know what it is. It's only one camera
That's six months after they're like, you know what? We're gonna release the DJI Mavic 3 pro. I
Had your also your drone certified. I have a certified drone pilot part part of it part of flying a drone is yet to identify hazards
Let's look around us
Let's look at this parking lot
Any one of these cars could be a hazard you could be a hazard you the viewer could be a hazard
Was we quiet Oh
Are you recording so are you recording now and on that? Oh my god, perfect. All right
I
Hope I can see this. Can we see what Riley's doing?
Where the odds of being that we're gonna crash it or like we go to business we bother business
I don't want to apply too close to the building. Yeah
Just close enough. Yeah, there's a can be turbulence. Oh, yeah, don't fight too close. Yeah, nothing dangerous. Obviously. Let's let's see what Cole comes doing
It's really nothing important right surely surely not just business development and marketing and human resources
German and
All right practice run. Let's go. Yeah, so you're good with that altitude and stuff too. Oh my god. We have audience. Hi. Hi
No, no, no, sure. I You're gonna be you're gonna mean the video if you don't move we're moving we're moving
If you want me a drone operator, what do you have to do being a drone pilot, there's a lot that goes into it
I make sure birds aren't gonna hit it. You're gonna make sure you're not gonna hit birds You want to make sure you're not gonna hit people you're gonna make sure you're not gonna hit
anything Oh, this is such a good shot. Yeah
Yes, so to be a drone pilot you have to take some exams
You have different levels of exams for different levels of operations
Um, I had to renew those
Certificates and credentials accordingly. Why did you decide to become a certified drone driver?
Uh, fire pilot Yeah, the reason I want to become a certified drone pilot is because I
Like anyone else in the pandemic Lockdown stuff in 2021 it's something to do that was like
Not around people So I was like, why don't I just run myself in the sky?
I don't own a plane. So drones the next best thing. Um, yeah, I just like spend time studying up different stuff
There's like a bunch of nice drone youtubers shout out to uh, uh don joist from don drones on he's a canadian drone pilot and
He's a stand-up guy uh
Just a all-around good good guy good good guy and good pilot and he has a whole bunch of resources for free on youtube
And I didn't take a single class I just watched his stuff and then I flew in areas I could fly. So what's the issue now?
So what's happening is that it's just uh
It's let me know that there's an aircraft in the area and usually in our area. There's sometimes low flying aircraft
so just want to make sure that
Uh, I'm not flying when it's flying essentially
It's good etiquette when you have an aircraft warning on your drone app or whatever
Is telling you your flight system is telling you if you're a drone pilot just land
Don't fly it next to a plane. If you had any recommendations for anyone who wants to take up
Uh flying drones, we'll just say to them. Um, yeah, take a look at
What kind of content you want to capture first of all? Uh, you can then it'll depend that it'll kind of make you choose the drone that you want
And then from there you can find out some look up some useful youtubers
In drone, well, I said John drones on Don Joyce. He's a great youtuber Canadian and that matters because
When you fly a drone, it applies to what country you're in
uh, American air four of their airspace laws doesn't really apply to Canadian airspace stuff when it comes to drones
Totally different exams. Totally different certification. So start there
Like comment subscribe This keyboard is already kind of jank this keyboard now I got to try this keyboard
Wait, so does it work? It works. So this has
Mirrors to tell you where the keys are, but they're also flip. So if you're going up, you're like, that's not right
Uh, so I'm typing hello to sammy and this is how long it's taking me. I'm using mirrors
Red
Rum
Done We're taking some more of the 3d printed metal parts and putting them through our centering machine from rapedia
This is a vacuum furnace from rapedia It takes the inside chamber of year and brings it down to almost a full vacuum
And then it fills the rest of what's left there with an inert gas called argon
And then takes the entire system up to around 1700 degrees Celsius. Yeah, it's uh, really toasty
And it does that in a very controlled way to take our parts
And get them all to not melt but kind of stick together
More thoroughly and it's called sintering the pieces together
It also burns off a couple of the binding agents that are used
Then after that it brings it back down to room temperature brings the atmospheric pressure back up
And then you can take the parts out and you get your actual steel parts
We have a couple of printed parts here. We have another larger version of the screwdriver handle
We have a little tiny ball peen hammer A couple of end caps and then a couple of key caps as well
And just for a bit of scale, no not that one just for a bit of scale
That's the size of a regular screwdriver handle Note how this one is quite a bit longer
That just comes from the shrinkage of the material as it's sintered
That's both some material burning off and also the atoms inside it getting closer together and bonding
Yeah, so when it comes out it will be essentially this size and I have measured previous iterations and
It's a lot more accurate than I would have expected So this is my first prototype of a steel screwdriver. This is the kind of piece you'd get after doing a little bit of post finishing
after it's sintered So it actually feels like a metal and it's strong and sturdy unlike the green parts which are
almost more like a clay So we have our individual pieces in at the temperatures inside the furnace
Most materials are not strong enough to be able to support the weight of things
So this is a ceramic separator and all of this gray is solid graphite
Because it still is strong enough to support things at 1700 degrees or so
So we load everything up
And then we have to put it into the furnace one other note here
This ceramic spacer serves two purposes one it lets gases and other things escape through the bottom of the parts
But it also acts as a separator between the steel pieces and the graphite if they touch
The the carbon will get pulled into the steel and essentially turn it into like um like a pig iron
Which is a type of a type of metal and its melting point is way lower
So it will essentially turn into a puddle of molten steel at the bottom of the furnace
Which is very bad This is fun because it kind of feels like opening up a sub-rein
Open and then this can either stay put or get pushed back in
Send me the model i'm gonna make sure it prints
This is what we call the the um, what's the word?
Spaghetti that you can't eat this is the forbidden spaghetti. So now this goes in
There are some guides on the inside once you're past the first little bit that kind of bump it up into the middle
And then we open it up
So this is an interesting phenomenon where something can get really really hot but not burn or oxidize
So in here, this is actually the hottest part. This section is going to be around that 700 1700 degrees
But as it gets further out, it's actually quite a bit cooler This is an area where you can get some atmosphere and some oxygen which will generally cause this discoloration
Whereas in here, there isn't any oxygen so it can't discolor
All right So we have a couple of different
Profiles here for this particular one. We're using the 316 paste and this is the rapid
Yeah, haha, funny center
So we hit it So this is that next you can see the cycle timer here. It's about 13 hours
So it's not fast and that's going to be a mix of the the temperature profiles to center correctly as well as the time to
Pull a vacuum and also the time to
Let the furnace get back to a normal temperature
So this time will capture all of that
13 hours Like the magic of movie editing
Movie magic of editing 13 hours then
And by that I mean a weekend After a little bit more than a weekend the furnace has done its cycle
So I'm gonna go in Okay
I'm coming In go And unlock the door
Okay
Touch screens are sort of there we go there. Oh, so it's now pressure equalizing so it was still a vacuum in here
And it's going for about another two minutes Give another turn open up
All right, so those are our parts it does still look like there's some discoloration
So this is something I've been working with rupitia on a little bit for our printer in particular
It seems like somewhere in the line where the argon comes in there might be a little bit of a leak
And that can that causes this discoloration. It's essentially oxidization of the metal as it's sintering
Though it's stainless steel when it's really really hot
it can still Rust my classical term or oxidizes a slightly better term
So this is what you expect to see in terms of coloration where it's all very stainless steel color
And up in the top and at the bottom you can see this yellowing into red into blue. That's the oxidization of
These I am going to polish Just to get rid of this oxide layer
And also get a little bit of Dimensional tweaking that I may have to do on some of them and then we'll be able to see the final result. Thank you so much tinen. Thank you
