CYBERTRUCK BUILD! (Part 4/4: It’s done!)

So at long last the half scale Cybertruck
is finally done. It’s one of the projects that were most
proud of here at Hacksmith Industries. We’re getting close to completing the
Cybertruck. We just need to finish the windows, painting, the tailgate, dashboard… Gibberish We need to add the weatherstripping across the top of the hinge. Oh and don’t forget the air struts, so the top window actually stays up so you can get in. And then we’ll be
ready for the grand reveal. The half scale Cybertruck…dashboard. You want to actually slide
it through the window? Make sure we don’t scrape. How do you think this going? Not great, turn it. I don’t entirely agree with what we’re doing but I’m not gonna stop it. That’s approximately what it looks like. So we just got the windows installed temporarily into the vehicle. So then we can align our
dashboard make sure that it’s perfectly straight. It looks good we’ll roll it
into place and then we’ll see if the marble fits in. Just be careful with the windows we don’t scratch them. So this side is gonna go underneath that lip there. How does that look like on your end? This side sags a little bit. So when we’re actually welding it
we’re gonna make sure to hold it up I’m pretty happy with that. Let’s put a
tack on either end and then we’ll be able to take the windows back out do the
full welds and hopefully make the mounts for these as well. Alright that’s it’s just
about perfectly. Yeah, looks good. Alrighty that’s it that’s all? No Cybertruck would be complete without
its unique folding tailgate design. I’ve been here trying to make it work on
our half scale model and I think I figured it out, let me show you how it works. So first we’ll have a hinging lid which will open
in order to access the mechanism. Then there’s two supports that will fold out
that’ll actually provide strength to the body of the ramp, and finally the ramp
will be able to slide out and unfold like a staircase so you can drive up it. There’s a lot of moving pieces in the design so it’s important that we have an
accurate model to ensure that when we build it it can unfold properly. Alright that’s the last little bit of
welding done on the tailgate so now we’ve got a nice working lid. So the next step is to assemble the whole thing let me show you how it goes together. Now that we know everything fits let’s go mount it on the vehicle. This part of the CyberTruck built was
sponsored by Raycon. I don’t know about you guys but wired earbuds suck The cables are always getting tangled they get caught on things. It’s just not
convenient break on wireless earbuds are Raycon wireless earbuds are the answer. The new E25 model has six
hours of playtime, seamless bluetooth pairing, loads a base, they fit great, and
come and awesome fun colors. They sound just as amazing as other top audio
brands you know and they only cost half the price. I even use them when editing
videos, and with several different earpiece sizes you can ensure a perfect
fit to isolate external noise. I even use them when doing metal work Speaking of fit could you do this with a
pair of wired ear buds? Plus they’re so comfortable sometimes I forget I’m
even wearing them. To upgrade your earbud game today click

more fun to drive when there’s actual breaks on it. With such a heavy truck
we have to make sure to be able to stop on dime. We’ve got the mechanical brakes
installed on the truck which are not only to be more responsive but also more
reliable than electronic braking alone. So our Digi-Key order just came in and
these are some of the last parts we’re going to need to finish up the
electronics in our Cybertruck and this is what I’m really excited about. This is
actually our power supply which will be able to charge our Cybertruck from zero
to 100% in under three hours and uses 220 volts which means we’ll be able to
charge it off of any AV charging station. Thank You Digi-Key for making this very
complicated electronics project very convenient. If you’d like to see the full
schematic diagram of the Cybertruck check out the link in the
description below. So what I’m currently working on is setting up the Canbus communication. between the ASI motor controllers and the tablet app. So we start off over here where you can see the signal being produced by the
controller that Ken Line is being picked out by the Arduino and translated to
show our voltage, motor rpm, motor current, vehicle speed, and the temperatures of
the controller of the motor. Finally it’s being sent over to the app
you’ll be able to display all of our information as well as control things
like our lights. Alright so we were planning on finishing the inside of the
Cybertruck using this fake leather vinyl wrap. The problem is we found out it’s
kind of hard to apply on the inside of the car. Usually it’s meant to go on the
outside of the car. there’s a lot of seams which we didn’t
really like look up and then if we ever want to repair it we’d have to make more
seams. So instead we’re gonna go with truck bedliner. Basically a black
rubberized heat coating that’s nice and durable. I think it will give a really nice consistent finish over the entire inside
of the Cybertruck and then we can also use that for the outside edges like the
fenders, and the bumpers. So let’s strip down the entire Cybertruck. I’ll get that truck bed liner on order and then we’ll be able to finish the Cybertruck. Now that the interior and the exterior
of the Cybertruck are dry we got to peel off all the masking tape and see
what it looks like. In the last video you saw exactly how
much torque this thing has. I mean literally we were making smoke in the garage just burning those tires out. We want even more torque so Stan’s
agreed to upgrade the rear motor for us. So it has even more power let’s go. Hey Bill! Good to see you. Good to see you. So we’ve got some new motors!
Yes we do. I’m excited. The motor that you’re gonna put in for
the higher torque application, what we’ve done is we used multiple thin conductors
in parallel. A lot of the motors that have high power motors that you see, have been wound by hand so that and they’re able to get the high currents through. The first motor you’ve run uses a hybrid magnet. We’ve taken a small amount of
neodymium and backed it up with a ceramic magnet. For our new motor
it’s just neodymium very thick neodymium magnets. You can have a higher flux level without demagnetizing to the magnet. The higher flux level will
just lead to higher torque. Between the neodymium magnets and the more wire
wraps we’re gonna be able to run more power through the motor, get more torque. The new rear motor has a hundred and thirty Newton meters of torque. Add that to the front motors with 720 Newton meters of torque together. Has 850 Newton meters
of torque. For comparison and F-150 v8 five liter engine only has four hundred
foot-pounds of torque at the engine which of course means we’re gonna
challenge it to a tug of war in the next video. So now that we’re done painting the
interior and the trim of the Cybertruck. We just need the finishing touches to
get this thing done. I’ve just finished programming an RFID
module for a Tesla Cybertruck which we use to scan the unique identifiers on
each one of these key tags if it matches what’s programmed into the Arduino the
trips this relay and opens our latch. It’s really awesome seeing the entire
electronic system work cohesively with the app. The driving mode tab allows us
to control things like our ignition, driving mode, gear shifter, and even
things like our door locks and tailgates. You can even open the charging port. The lighting tab gives us full control over
every light bar in the entire car, including the headlights, off-road lights,
interior, truck bed, taillights, and fog lights As well as a hue and brightness. Finally the motors control tab shows all of our canvass information for
every motor. These are the finishing touches to give the Cybertruck done. Alright so at long last the Cybertruck sorry the half scale Cybertruck is finally done. It took a bit longer
than we expected I think when we first started out we were expecting to finish
it in like two weeks. Which wasn’t really realistic especially
with all the design and project creep we had. We just kept thinking of all these
cool attachments and bells and whistles to add to this thing which ended up
making it awesome like the charge port. Like we can literally charge this at any
EV charge station that’s freaking awesome. All the LEDs, the iPad as the dash, even the marble dashboard like we didn’t have to do that at all but
because we did it’s a really polished project and I think probably one of the
projects that were most proud of here at Hacksmith Industries. Now you guys might
be wondering how much did a project like this cost to make? Well component-wise there’s about $10,000 worth of parts in this not
including the motors and speed controllers that we got for free from
Accelerated Systems Incorporated. On the labor end of things we’ve put about $40,000 worth of time into it which means this half scale Cybertruck cost
more than a real Cybertruck! Crazy right? That’s the cost of prototyping
things. Cars are only cheap because of mass production. If I had to guess I bet the real cyber truck prototype cost upwards of a million dollars. Anyways we have a super awesome test planned and grand reveal video make sure you’re
