in our last video we showed you how to
assemble some of the electronics inside
our flamethrower arm and in today’s
video we’ll be finishing those up and
testing it out on my arm
one propane canister runs out fairly
quickly so I decided I wanted to add a
second one I wanted to build something
that would let me use two propane
canisters at the same time for double
the fuel capacity for that we turned
back to our small little brass pipe
fitting pieces this is what I came up
with we’ve got our valve in fact we’ve
got two of them this is what we built
earlier by soldering on pieces you can
see the copper little pieces soldered on
to both you can see the knob spaces
soldered closed so there’s no leakage
there on one side it’s pretty direct the
valve goes through an elbow into the T
which threads down into our Barb what we
can do is we start with this side with
it closed thread our tank onto here
thread our other tank onto the other
side then we can open and we have both
tanks at once feeding down into the Barb
and then I’ve got this this is just a
block of wood I cut out of a plywood
it’s sort of T shape that lets these
hose clamps and grip on and pulled it
firmly in place and I’ve added a little
elbow bracket onto the top of that which
is what I can use to attach this whole
weird assembly on to the skeleton arm
frame and now I can bolt that on right
there I’ve drilled two holes into the
frame that goes right there now if I
just had this mounted onto the arm and
to pull propane tanks above it that
would be a lot of stress on this one
little piece right here so we wanted to
build a support that could hold
everything in place a little bit higher
up on the bottles we’re just going to
cut that out of a piece of wood looks
like about two and thirteen sixteenths
inches is the diameter of our bottles
take a compass measure out a circle just
the right size but just the right size I
mean chest a hint bigger so that it’s
not gonna scrape and rub we’re gonna go
for some open circles they won’t be
entirely enclosed by the board how to be
open on one end just a little bit see
let’s see we’ve also got some extra
board back here so we’ll trim that down
a bit too
our piece of wood is cut out and if we
measured it correctly the bottles can
fit through this and then directly into
their valves so I’ve got two propane
cans that are completely empty there’s
nothing left in these they don’t hiss
when you push down the pins nothing
remnants so I’m not going to be risking
filling the air with propane as I do
this there we have it two propane cans
and I just said these are both
completely empty that’s why nothing is
venting out here these are just drained
so now I can mount this on to the arm
skeleton and it should hold those pretty
nicely I’ve got one elbow bracket right
here let’s throw a second elbow bracket
onto this piece and that’ll let us
attach both of them lovely lovely I love
you this brace is working well it’s
holding our canisters right where we
want them alright next up we’re going to
want to attach the solenoid and then run
the hose from this barb into the
solenoid where did I put the solenoid
the solenoid conveniently for mounting
has a couple of spots on the bottom with
threads in it so we can use a couple of
machine threaded screws to attach that
and to attach it to the arms we’ve got a
couple of holes drilled into the metal
our hose reaches to the solenoid and in
fact we’ve got quite a bit of extra hose
so what we want to do is cut it to a
length so that it easily reaches my arm
is bent or straightened out all right
straight bent both ways that hose
reaches just fine in order to dump the
propane out we need to be able to
activate the solenoid and to do that we
have our battery pack of course so we
need somewhere to put the battery pack
I’ve got some space up here in between
the propane tanks and it seems like it
would be a shame to waste that I’m gonna
see if I can’t attach our battery pack
up here
there we go that’s held nicely in place
we’re gonna take apart this umbrella and
use the spring-loaded metal bars as a
sort of extending arm and try and make
our prongs reach out onto the front of
that so all of the electricity is just a
good distance in front of our arm that
way there shouldn’t be any fire on our
hand there shouldn’t be any Taser leads
on our hand it should just be safer all
around okay I think I need to completely
destroy this umbrella the umbrella
mechanism is pretty simple here we’ve
got one metal rod that fits closely
inside of another one there’s a lock
that doesn’t move until you press down
on that it collapses down normally what
holds it in the down position is some
other hardware that I’ve already
stripped off we do have these little
barbs down here but they don’t latch
onto anything at the moment so what I
need to do is cut a hole in the metal
right here so that it’ll hook on to
those that way when I push this button
it should spring out we’ve got the hole
cut well filed in so now we can bring
this back and it latches into place and
when we push this button down mmm it
shoots forward as you saw it’s quite
difficult to push that button down this
spike is a little more intense that we
need it to be so once again we reuse the
file we’re gonna keep this bike there or
we’re gonna shorten it so we don’t have
to push quite so hard on this button
here is what we’re going to use to
extend those Heiser diodes I have these
two leaves that have sort of a ceramic
non-conductive back and of course the
metal up front at the back of these
leads
I have soldered on these two wires and
covered the backs in some liquid
electrical tape and I’m now actually
going to put several more layers of
stuff over that make absolutely sure
that the electricity isn’t going to try
and arc between the wires back here and
that it really sticks to the leads where
I want it we’re also going to attach
these onto the front of this telescoping
rod and now I need to drill a hole big
enough for the screw to fit in and I’m
then going to add some proto cutty just
some silicone mixed up with some water
or maybe a little bit of cornstarch to
just build up around here
now if we attach this umbrella bar right
about here you should be able to press
this button and it will extend
automatically so we need to attach the
umbrella bar onto the frame to do that
we’ve got a hole drilled right here
we’ll drill a hole into this and use a
alright this arm is attached on one side
but doesn’t have much support on the
other so what I think we’re gonna do is
take this eye bolt you’ll attach that on
to the front of the frame right about
here and that’ll just sort of be a spot
where this can rest and we’ll then
tighten this bolt down once we have an
angle we want and the advantage the eye
bolt is that it should hold it in place
and as it extends outward it should be
able to slide along that still giving a
little bit of support but without
gripping it so it doesn’t slide easily
[Music]
[Applause]
that’s what we’re looking for
I needed a handle to be able to control
both the gas and the electricity at once
this was originally part of a wrist
rocket and I thought I could repurpose
it to be my little double trigger handle
so what I’ve done is cut three holes
into it I’ve got a rectangle hole that I
cut in right here and I’ve got two more
holes that I drilled down in the bottom
and then it already had one hole in the
top that happened to be just the right
size so what we’ve got is a couple of
different kinds of switches so this
switch is designed to do something
rather particular you can have
electricity going into it and you can
have something that is activated by the
switch and then something that is always
on the second wire is the one you want
to be conditional we are actually not
going to be using this wire the one that
is always on so we’re just going to cut
that off now this switch can mount
inside the rectangle hole that I cut out
and if I live in a space I can still
click it we’ve also got this little push
button switch both switches only allow
electricity to flow through as the
button is held down this one I’m going
to put on top and it’s going to be the
activation for the Taser and then
pulling the trigger will drop the fuel
beautiful we now have two separate
switches we can activate
click-click click-click so use a couple
more zip ties to attach our switches to
this other piece of aluminum
from a functional standpoint this
flamethrower arm should be ready to go
try to suck her out yes we’re not using
it a whole lot right now basically we’re
just showing you that it is functional
and I’m pretty happy with where we’ve
gotten this sue it does work it shoots
fire it’s not mounted to a chair anymore
I can carry it around it’s got some heft
to it it’s not exactly a super
comfortable
flamethrower arm but it does work all of
it is mounted just on one arm right
there this thing is pretty sweet stay
tuned for part three where we decorate
this whole thing in some cool cosplay
style armor and make it look like a
giant robotic arm guys as always we’ve
got more for you to see so you don’t
miss out on the fun this box up at the
top will take you to our last video
that’s a good one you should go check
that out the box down in the bottom
that’s gonna show you what YouTube
thinks you need to be watching and this
bond here in the middle will subscribe
you to the channel this is how you make
sure you don’t miss out on anything cool
what we do in the future don’t forget to
ring that Bell and we will see you in
the next one talk to you then
