we had so much fun building Rhinehart's
rocket hammer on this episode of make it
real we're going to build toward your
owns turret now obviously we can't make
an actual automated turret with say a
gun or something so we're going to be
using a paintball gun instead this
project is made possible by digi-key
percent us all the electronic components
we needed for it overnight
all right but first let's back up a bit
we've been mean to make an automated
sentry turret for a few years now ever
since we acquired this stage gimbal see
these are actually used for stage lights
at a theater kind of like this but it
wasn't until one of our new employees
Bogdan took an interest in this project
and started working on it
[Music]
all right so how does it work we
designed the tert to have two different
modes automated tracking and manual mode
for automated tracking we're actually
using a pixie module which is our dueño
compatible color sensor board which does
all the processing on the board I
actually back to pixie on Kickstarter a
few years ago and now it's ready for
purchase immediately oxygen key calm for
a complete explanation of electronic
system please visit maker IO
more information links in the
description below we've programmed the
pixie to track the blue of Captain
America shield now let's see if we can
actually track it using the turret so as
you can see the turret is following the
blue signature of the shield when we
flip the shield over there's no longer
any blue in the field of vision for the
camera which means the turret stops
tracking now the automated tracking is
really cool but we also have the manual
mode so you can use it with a remote
switch plug it back in and grab your
remote what does I mention how strong
this thing is it uses two 24 volts gear
DC motors and as you can see okay
got their power to it and in manual mode
you can use the FPV module to see
exactly what the tur is you may have
noticed this doesn't quite look like
toward your arms turret so let's fix
that Q do it right
[Music]
now to make part of the turret we're
going to be using some flexible mirrors
that we purchase from a dollar store
and answer the age-old question see
laser Emir
all right now that we have our mirrors
they're going to be mounted to this 3d
print part the problem is we actually
have to put a bend in the mirror and
normally you can do this by using some
kind of heated wire with a bending jig
but did you know you can actually use a
laser cutter to do this as well so what
we're going to do is actually D focus
the laser until the laser beam is almost
a centimeter in diameter which means
when you cut that line break here it's
actually just going to keep the plastic
then we can pull it out and bend it to
shape
[Music]
stay tuned for the next video where we
test to our view and turrets to the
limit we're going to light completely
lots of painful also make sure you hit

enough for you all with some social
media we post pictures almost daily
thanks for watching
