This is the world's first fully
functional real-life Minecraft Creeper.
And in this video, I'm going to show you
just how one goes about building every
Minecrafter's greatest fear.
And of course, we're going to blow it up.
So a couple of years ago my dad
purchased a few "big booms" at a fireworks
stand for the 4th of july.
These "big booms," which is what the vendor
called them, turned out to be pretty epic.
For the years following, we used them to
blow up our gingerbread houses that we
made at Christmas,
along with a cake. A few months ago i
discovered that we still had one left,
so I decided it was finally time to
build something I've been wanting to
build for the longest time:
a real life minecraft creeper that
actually explodes.
So I wanted this thing to be as close to
a real creeper as i thought i could make
it.
It needed to be able to explode when it
gets close to something in the exact
same way a minecraft creeper explodes
when it gets close to a player.
And I also wanted this thing to be
remote controlled, that way I could
actually control it and it wouldn't just
run around blowing people up.
So, over the span of three months I built
it, but for your convenience,
here's the short version.
After a little bit of CAD, some wiring,
and a lot of troubleshooting, I finally
got this thing to work.
But before i take it out into the real
world, let me show you just how this
thing works.
So what allows this creeper to actually
move is a remote control car that I
bought on
eBay.
Basically I just cut the car in half,
installed the steering into the front
legs, and the motorized wheels into the
back legs.
Now, in hindsight, i probably should have
used a more powerful remote control car,
and I definitely should have made the
steering a little easier.
Making it move was the easy part, the
real challenge came when trying to
figure out how to actually make the
Creeper explode.
So my first idea was to use a lighter
and maybe set it up in a way that there
was like a switch connected to the
Creeper's foot,
so when it ran into something it would
light the fuse and blow up. But obviously,
that was a terrible idea. So I had to
come up with something different.
So what I ended up doing is using an
ultrasonic sensor connected to an
Arduino UNO,
which controlled a relay, which turned on
and off a heated coil.
So basically, whenever something came
within a foot of the sensor it would
turn on the coil and as soon as it left
it would turn it off. Oh, and I also added
this led that turns on and off with the
coil,
that way if the creeper doesn't explode
I can see if it's because the sensor
isn't going off,
and i don't have to worry about getting
blown up, because I can see the led from
a distance.
I probably should have added more safety
features and you'll see why in a minute.
I also added some flour next to the
explosive just to make the whole
explosion appear bigger and look more
Minecraft-like
but when i did this i wasn't actually
aware that flour can be extremely
flammable if used in the wrong way
and by using it in the wrong way i don't
mean a simple baking error
so yeah there's that so for the remote
control i simply place the guts of the
old remote control into the new housing
that i 3d printed
now the creepers whole purpose is to
blow up steve so naturally
i made a cardboard steve i also made a
few blocks so that steve could build a
house
originally they were supposed to be
planks but now they're just weird
alright guys the time has finally come
to blow this thing up let's do it
so it's been a few minutes and this
thing still hasn't exploded so remember
how i added that led
it's kind of hard to tell right now but
the led is actually on
so that means the coil's on and the only
way i can safely figure out what's going
on is if i first turn off the coil
alright so it turns out the problem was
just the coil came off of the fuse
so now i tightened it back on there so
now it's time to blow this thing up
all right same problem but i fixed it so
now it's finally time to blow this thing
up
let's see that one more time
as you can tell we were a little excited
all in all i'd say the project went
really well and the explosion was
actually way cooler than i was expecting
some of the pieces even flew pretty far
surprisingly the flower actually worked
perfectly in making the explosion look
bigger and not in making a massive
fireball
which could have actually been kind of
awesome but if that did happen then
steve probably wouldn't have survived
speaking of steve i'm not sure what
kinds of hacks he was using since he was
able to take an explosion from less than
a block away
and come out totally fine minus a little
shrapnel
but maybe the creeper is actually using
hacks too because its feet survived
and they work perfectly
for those wanting to see a little bit
more of the creeper here's a nice little
compilation
