ever since we made Captain America's
electromagnet shield we want to make a
pair of electromagnet gloves that would
allow us to climb buildings just like
spider-man many of the components
required for this project will provide
to us by digi-key who sent us all the
parts overnight at the core of this
project reason the same electromagnets
that we did for Captain America's
electromagnet shield and as you can see
there are more than strong enough to
hold me up
in fact at just 12 volts one of these
electrum and 20 kilograms of lifting
force but we're running them at 72 volts
six times the rated voltage that means
they produce 720 kilograms of lifting
force together that's over three
thousand pounds now unfortunately
running these at such a high voltage
means they heat up really fast and if
you leave them on too long they'll
actually burn out and break
[Music]
we might need a way to measure the
temperature to make sure we're not
overloading them now the next step is
making the handle
we'd like to use our 3d printer but
we're not too sure if the part will
actually be strong enough for me to hang
on so we printed a prototype and we
decided to give it a shot so we want to
test this to make sure that the layers
don't delaminate when hanging this way
it's super strong this way because the
sheer strength of the 3d printed part
along the horizontal plane is really
strong but intention is typically a bit
weaker because of delamination
[Music]
I was a magnet yeah alright so test it
with a safety factor I'm gonna throw on
a 50 pound weight vest and do that same
test over again but we're gonna have to
up the voltage of those magnets because
I actually managed to break the magnetic
field during the last test you grab me
another battery in two hundred pounds
remember we're running these magnets at
about six times the rate voltage so they
do get hot luckily it's winter all right
there should be cold enough see if we
can break it just in it yeah that's
really hard in the air well it seems
like the handles that we made using
aren't as six 3d printer and the Morse
true der we're strong enough we're
actually quite impressed we thought they
were going to break but a lot of people
have mentioned that the more scooter
seems to provide superior layer bonding
for your 3d printed part and I think
this is pretty good evidence that does
now you may have noticed this isn't the
same handle that we tested that's
because we actually revised the design a
little bit to make room for the
electronics which is the next step from
this project
[Music]
all right we have a first prototype made
let's go over how it works well not
completely necessary we added an LCD
screen to give the user feedback on the
device as you can see it displays the
current voltage the temperature of the
electromagnet the elapsed time of how
long the electromagnets been on and the
power level of electromagnet which is
adjustable to ensure we don't
accidentally turn the electromagnet off
the switch is actually latching so that
means you tap it to turn it on and then
you don't have to hold the switch down
in order for the magnet to stay on
simply press the button again and it
releases the magnet all right so now
it's time to make the final version
we've already 3d printed some nice black
handles now we just have to assemble
electronics and we'll be ready to do the
final test for a full schematic and
explanation of how everything works

[Music]
thanks with me
Hank's with me it's not suspicious at
all the hell's inside of that
I think we need rubber man
alright so in that test we're actually
slipping down the middle because was
metal-on-metal we've added a bit of
rubber and now it should be good to go
so let's go test it just be careful the
attendant
with great power
it's great responsibility we hope you

watching I feel like we didn't think
this too
