Hey everyone we've got a really cool project for you this week as you know I
love movies like a lot, and it would be really awesome to go to the drive-in
theater to watch a blockbuster film in my 1979 MGB spy car the problem is most
drive-ins around here have actually closed which is a real shame because I
really wanted to go on an old-school date and as you guys know I'm working on
a spy car right now...
I'm talking rocket launchers under the headlights a
grappling hook launcher in the grill and for romantic nights out a built-in
projector so you have a movie theater wherever you want yeah that's right I'm
gonna be making my own personal drive-in movie theater in fact LG liked our idea
so much they decided to partner with us on this project to help us make it super
epic. They sent us their new CineBeam 4k laser projector it's one of the
brightest and smallest consumer projectors on the market it's
transformative design allows it to be used almost anywhere okay
so I've got my classic car and this awesome projector all I have to do is
put them together and I'll have the ultimate portable drive-in movie theater
the only hard part of this project will be finding a date...
Well that's a future Hacksmith problem let's get started!
So this car was made in 1979 that actually makes it 11 years older than I am and
personally I think this is the perfect vehicle for a drive-in movie theater now
all we have to do is figure out a way to power the projector off of the car and
mount it. Just gonna plug it in and we can see where we can mount this...
that's not too bad, now where else can we put it
maybe something like this
Now this is a rather small car but luckily the projector is pretty compact
so I think we could fit it around here somewhere but we might have to design
some kind of mechanism
Now the funny thing is before I quit my job to do YouTube full-time I actually
worked for a company that designed and made digital
movie projectors the only difference is they're about a hundred thousand dollars
and absolutely massive it's actually really impressive to see that LG has
been able to shrink this technology down into a consumer product that's actually
a very affordable price. Mounting this permanently in the car is actually gonna
be a bit of a challenge so let's go to the computer and start looking at some
3D models
All right so to make the mechanism to actually raise the
projector out of the MG so we can point it at the movie theater screen we're
actually gonna design it in CAD, now the software we use is called Solidworks and
the reason we use the software is because both Ian and I have a lot of
experience with it I'm talking over ten years I'm actually a certified
SolidWorks professional the other software we're gonna be using is called
grabCAD now grabCAD is actually a website that allows you to share your 3d
models with everyone else in the world for free and actually we have a lot of
our projects on there if you guys want to check out our profile there's a link
in the description below but the other feature it has is a private cloud for
you to share your projects with other people in your business or your team so
we actually had Bogdan measure up the projector and create a rough model of
the projector which will allow us to design the mechanism around it so let's
just add in some of the parts so we're gonna be using a linear actuator to
actually move the projector they're easy to use, they're electrically powered, they
take about 12 volts, make a bracket, add in some other parts
and there we go one projector mechanism and as you can see goes from close
position all the way up into open all right let's build it
Alright gonna cut out side pieces, pull that out, set it down, then just have to trace out pattern
And then we just cut it out!
oh really really really really no I'm
No, I'm just kidding we're actually gonna be using our maverick CNC plasma cutter
they've got from elite metal tools I've already loaded the dxf in so I just need
to press go and it'll cut it out
If you guys are curious about how the circuit actually works
check out the circuit diagram at maker.IO
all right now that bogdan's finished up with electronics we are ready to
permanently install this into the car! oh man this is heavy
why do we make all of our projects so heavy this projector was so light before
we added all this steel to it. Now we just have to screw it down
Plus, the projector ships with two wood screws for installing into your spy car
All right now that we've got the projector mounted in the car we need to power it
somehow the funny thing is consumer electronics actually run off of DC power
what you find in a battery but because they're designed to be plugged into the
wall which uses AC the power supply inside of consumer electronics actually
converts AC to DC to power the electronics now a car battery which is
12 volts DC would actually run most electronics but we don't want to take
apart the projector to bypass its internal power converter so what we're
going to do is actually get a power inverter now this will take 12 volts DC
and convert it to 120 volts AC which will feed into the projector which will
then convert it back to DC, woohoo! electricity
now the protector itself is actually extremely power efficient because it
uses lasers we used a power meter to see how much power it actually draws from
the wall and it's only a hundred and fifty two watts that's like two
lightbulbs old-style projectors that use xenon lamps are more like 1500 watts or
ten times the energy consumption as this projector which is really cool so we
actually kind of oversized the inverter just a little bit this is actually a
2000 watt power inverter and the reason we did that was we're planning more
gadgets for the car and we want to make sure we have enough power to power everything
That's less than a light bulb, and it's 3000 lumens! How do they do it?
but the ultimate test it's overkill power supply it's for the car to power
the projector we make our portable drive-in movie theater and the only concern I
have is this does not actually put out a pure sine wave as you would get from the
wall, it puts out a modified sine wave, whatever that means
so hopefully that's not an issue... hooray!
Isn't that a beautiful image
Now what's a spy car without a license plate flipper now unfortunately license
plate flippers are illegal so what we're actually going to do is
going to put a decorative license plate flipper on there while maintaining the
real license plate right here
the control box complete with remote control
all right so we've got all electronics in the trunk now and as you can see we
actually put a second car battery in the trunk as well and that's to power all of
our auxiliary spy gadgets but I think we're missing one thing
Ian yeah that's right a Hacksmith Industries branded fire extinguisher!
Alright now we can test it
Alright so inside the cigarette ashtray we can turn on the inverter like
so now it should lower
Thanks now we just plug in the projector like so until I open it right there and
if you put switch the other way up it goes
Adjust the mirror hey gotta turn lights off, lights!
not too bad all right that works pretty good now it's time to go on my date
Man, why did I pick such a far location to do the drive-in it's really boring
Wait a sec...
closed good thing I brought my own
Well, nothing beats an old drive-in movie theater especially when you bring it
wherever you want to go now time to watch my favorite youtuber
Alright that works pretty darn good this projector is 2500 lumens which is super
bright for a home theater projector it's recommended maximum screen size is 150
inches but even projecting a video on the entire side of a gray building it
was still completely watchable now for our final test we're gonna set up our
own proper size 150 inch screen in the park and have our own little drive-in
movie theater for the entire neighborhood let's get set up
all righty show's over
Alright that was awesome huge thank you to LG for sponsoring this project and if
you guys want to learn more about the CineBeam 4k laser projector check
out my links below it truly is an awesome projector as for our spy car
make sure you subscribed with notifications turned on, we will be adding jet engines
tire spikes, missiles, smoke screens, lasers and more very soon
