Hey Hacksmith, do a kickflip!
Hey guys, on this episode of Mak-
On this episode of Make It Real we made a fully electric skateboard that can
kickflip on command
which means...
All I have to do is press this button
Man this game takes me back I used to play Tony Hawk's pro skater
all the time back in grade school
When I heard activision was coming out with
Tony Hawk's pro skater 1+2 remastered I almost had a nostalgic
heart attack and then when activision reached out to
ask us if we could build a self kick flipping skateboard
for the release of the game
well my 10 year old self
would not believe what i'm doing today
Now I never could do a kickflip back in the day
I wonder if I can do one now
Go skater James!
Alright if I want to kickflip anytime soon I'm going to need this board to do
two different things
Number one: it needs to drive by itself
Number two: it needs to be able to kickflip
now making it drive by itself
that's the easy part you can get DIY electric skateboard kits
online quite easily you need a speed controller battery and
then we've got this micro controller
The challenging part here is we want to be able to control it with a playstation 4
controller which means we need to communicate with the board over
bluetooth- Hey Ben, you think you can do that for me?
- What...?
Alright now the fun part I need to
figure out how to make this thing kickflip
Alright test number one let's
prove that we can do a kickflip by
putting some amount of force
onto one of the bottom edges of the board
so hopefully if I go like this
triple kick flip first try
all right that's good
let's see what else we can try
Oh it's getting more power
let's try something a bit more explosive
oxyacetylene balloon
perfect, safety first guys
Alright that's not gonna work either
we need some more serious firepower
so this g-class rocket engine is the largest rocket engine you can buy
without needing a professional rocketry license
I strapped two of these to my wrists
to try and fly like Iron Man
so I think it might cause this to flip
I think for this one we should probably
go outside because uh-
yeah rocket engines
It's armed now which means when I press this big red button that rocket
and hopefully the skateboard is doing a kickflip
3...
2...
1...
Fire!
HOOOOLY-
That's a world record right there
that was like uh-
I don't even know what you call numbers that high
Alright we've got the airbag now
3...
2...
1...
I mean I guess that worked
it flipped
but I don't know how we're gonna mount
that to the bottom of a board
I've got it!
Springs!
Alright Ben what do you have for me so I have the hub motors communicating with
the electric skateboard speed controllers and they're being
commanded by an arduino that's been paired to this ps4 controller here
give it a shot
Maybe not that hard - Okay yeah
Yeah!
Alright I can work with this
i'm gonna take this
put on a skateboard
in the meantime
I need you to make a giant mousetrap
-What? Awesome
Alrighty I got all the parts
now we just need to build an electric skateboard so the deck is actually a
Birdhouse official Tony Hawk deck made for the game which is pretty cool
so let's start assembling it
[DING]
Huh that must be the 3d printer
Alright we've got our electronics enclosure straight off the 3d printer
which means we're ready to install it
Now we can install the electronics so
we'll start with the charging port
For more information on how the self kick-flipping circuit works check out
our page on maker.io
[Disclaimer Hacksmith industries digi-key
and activision are not responsible you build your own self-care flipping
skateboard get hurt using it the team here are professionals who often get
hurt and trust me it sucks getting hurt]
We didn't actually have a switch that
was high enough current rated for the battery so we're actually using
a battery connector as our main power switch and it plugs in right over here
all right so we've got some lights
blue light, blue light, green light
it's gonna work
Ha-ha!
It's done let's try it out!
Mad air!
Alright that was awesome now we just need to make it flip
I gotta go check on ben and see how my mousetrap idea is going
Alright so ben sent me a design for his metal mouse trap let's take a look
Alight well that looks like a skateboard here's the uh
kick flipping mechanism we've got two really big springs
oh look at that, I think that's actually the archery trigger release we used from
the spider-man web shooter project with JT
which didn't work so well
Hopefully we have better luck this time
when you pull these back
it should do a kickflip but wait how do you even do a kickflip
well it's a good thing I have Tony Hawk's pro skater 1+2 remastered
edition let's try it out!
There are links in the description below
if you want to try it yourself
Alright so to do a kick flip in Tony
Hawk's pro skater all you have to do is hold down the jump button
and then press the flip button as you're holding left
and bam kickflip
360 flip!
So that's exactly how we're gonna make
our skateboard kickflip as well
but let's get serious
Alright let's go build this thing
So this is the largest torsion spring that
you can buy off the shelf and it's not big enough so we're gonna make our own
to do that we're gonna use this spring steel which is incredibly difficult to bend
so we're gonna use this mandrel on the
lathe and then power feed
Alrighty time to assemble our steel mouse trap
Alright it's built, let's test it out
Oh god this is terrifying
I got it!
Say goodbye C4 can
We're doing it!
Wasn't that bad
this one might send shards of plastic at people
And that kids is why you don't make a metal mouse trap
Alright we've got the
kick flipping mouse trap mechanism done which means we
just have to install it
plug her in...
Alright that's the last screw
which means, test it out
This thing is terrifying!
Alright let's see if it kickflips
That was freaking sweet!
It works perfectly
Now we just need to put some grip tape on here and be ready for the big test
Alright today is the day I learn how to kickflip
using a self kickflipping skateboard
It should be as simple as jumping in the air
pressing the button
and then landing on the board again
OOOOHHHHHH! WHAT?!
My first kickflip at age 30!
My first kick flip at age 30!
Two for two
Hang on, I'm getting a call
Dude it's Tony Hawk!
Hey James it's Tony Hawk I just want to congratulate you on
your very first kickflip at age 30
I know that you didn't necessarily
do it yourself but you kind of did because you designed
a board that would do it for you so I am impressed
Um- I never thought I'd
see the day that a board would be self kick flipping so
congrats on that um it actually kind of sounds scary but
you did it, I saw it, congrats!
Thanks Tony!
That was Tony Hawk!
So we test it in the
shop let's see how it does in real life
Alright let's try a double kickflip
Yeah!!!
Hey Hacksmith, do a kickflip!
Alright this is an awesome build huge thank you to Tony Hawk's pro skater
1+2 remastered edition for sponsoring this video
check it out in the links in the description below
Let's see if I can
kick flip right here
