hey guys we have a super exciting make it real planned for today
spider-man's web-slinger's. I think this is probably one of the most requested
projects we've ever seen on YouTube and to help us out
JT's come all the way from South Africa for a second Hacksmith Internship
good to see you James. Good to see you too JT.
It's cold out there. Long walk from South Africa.
Well it is Canada. So you got one month to make spider-man's web-slinger's you already
did a great job with the Just Cause grappler okay I think we knew some of
the design principles that you used on that yes to make actual working
Spiderman web-slinger's and we'll actually able to swing from the rafters at the shop.
Think you can do it? I can. You know what? I've always wanted to do that. So, sounds perfect.
Awesome. Let's get to it.

Mike Magic Heroes: Era of Chaos is available on Google Play
it's a super fun RPG game where you join Queen Catherine Iron Fist
on a quest to restore the Kingdom of Erathia with a
massive story campaign you explore a huge world, grow your army, and conquer the lands.
Collect mythical heroes with unique powers and upgrade over 40 plus
different troops and creatures. It's bright and colorful graphics our anime
inspired and immerses you in a fantastic world. Plus with the PvP duels, you can
challenge other people in real time. My favorite part is that you need strategy
to win the fight by placing your troops in the right position can mean the
difference between glory and failure. Try it out today by downloading on Google Play

so one of the main challenges in making spider-man real is that you have to be
able to release the webs while they're under huge amounts of tension. Now instead of
designing a mechanism I thought I would use an archery release. I was a little
skeptical if it would hold my weight, so we decided to put it to the test.
Let's swing bigger!
you touch it...and it goes..
There we go. That was not me.
literally just snaps under 150 pound load. Let's get some of that rope and use this
and tie it around instead.
think it will hold?
Spiderman!
Was that you? I don't know.
so that was not really according to plan. Winded me a lot. hopefully my knee's ok.
in retrospect that should have been a bit more expected... but oh well
now I just need to make sure that the next design doesn't let that happen
so I'm going to use this instead it's called a snap shackle they use them on sailing boats
to be able to release under high loads and it's just a lot stronger and more
reliable than the archery release. Now I'm just gonna need to design and build a
mount to go on my wrist. Let's go do it
I'll just use a servomotor here to be able to electronically actuate the pin on the snap shackle.
So, in the comics and movies, spider-man's webs can stick to anything with infinite strength.
But since that's not possible we're gonna use grappling hooks instead. however grappling hooks
can be big and heavy and kind of dangerous if they fall and hit you in
the head. So I've designed something different.
I don't know if anyone's ever built something like this before but what I've made is a specially designed
grappling hook that just fastens to its own string. This means it's going to be
safer as well as smaller and lighter. What I've done is I've built three of
them and an overhead bar here and we're just going to test out which one's the best
so it looks like this one is our winner didn't work every time unfortunately but
I was still impressed how often it did now all I've got to do is make it out of
stainless tube so we can launch it out of our Spiderman gun.
so now we've got these cool grappling hooks we need to make some barrels to
fire them off of.
James gave me an amazing fancy solenoid valve so I've
made a little test gun to see how well it's going to work it's a barrel welded
to a nut tightened to an adapter that I put in the valve and then a nice wooden
handle a battery that activates the solenoid that opens the valve so let's
test it out on safety chicken
right so now we've loaded our cartridge we'll use
this test grappling hook I made with no hooks and see how well it works.
Safety chicken this town ain't big enough for the two of us.
so, to keep the wrist launchers as light and streamlined as possible I
decided to put as many components as I could onto a backpack now the whole
thing runs on compressed air and this goes into a valve assembly I made which
fits into the backpack like so. This splits the high-pressure air into four
separate streams and these valves block the air until you put current across the
solenoid here which will open up a piston and allow air to rush through to
the barrel of the wrist launcher. These are the electronics and the smarts of
the project. You plug in a battery here and that powers the solenoids here with
the valves as well as the servo motors here it also powers a regulator which
takes the voltage down to a level that's safe enough for the processors to use
the processors are the logic of everything they primarily control the
shooting and releasing so that when you shoot the first time it will open up
valve number one to shoot the first hook and when you shoot again it will then
shoot the second hook it does this by sending signals through these pins here
and it does it when you give a signal through these wires here.
The signals are sent by this glove that I made right here. You plug it into the processor this
allows you to control the web-shooters using hand signals so by bridging any
two of these contacts that I've made on the glove such as the classic spider-man
hand gesture you're sending a signal to the microcontroller to fire the launcher
and once everything else is assembled you cover it all up with my custom
spider JT logo.
To see exactly how JT's electronics work check out our circuit diagram on maker.io.
alright, so last time when JT fell, it wasn't that safe.
let's try it again this time with mats.
ah this is sweet, JT you gotta try this
so unfortunately at the last minute we just run into some problems that I can't
solve in my time left here so we're going to do a paired back test with just
two hooks see if I can swing once shoot the other one and get it to hook all in
one go
not quite would you mind reloading that for me
almost. well we'll call it a day that was a bit of excitement no no no no well
I guess I'll live here forever now
alright so that was freaking awesome one
of our most most common fan requests is to make spider-man web-slinger's and as
you saw in this video so far it is not a simple task JT's been working out for
about a month now his entire internship here and we got so close to making it work
so much of it worked flawlessly and then just a few small
things ended up causing big headaches but if I had a little longer it could be
so much better. on the plus side there are a few design revisions that we
can do to hopefully get rid of those issues and make it working either way JT
is going to be taking these parts back home with him to South Africa and you
can follow him on his channel built IRL to see the future of this project we're
still going to use this one and hopefully get two swings in later on in this video.
but we gotta get to the airport
yeah I'm literally leaving in like three hours sorry okay mmm I probably want to
change how security is not gonna like this right now Security's gonna be mad
right now okay
As you saw at the end JT's test he
was stuck hanging well I guess I live here forever now the release mechanism
wasn't actually working that well it turns out once this is under load when
you're actually hanging off of it it makes it much harder to actually release
and I won't be able to release either cuz it's not working
So, that's what we're gonna work on fixing and then we're gonna see if we can do two
webshots two swings and a release
now since we're only going for one swing we
don't actually need both of these quick releases anymore so what I think the
easiest solution to get us to a working test would be we remove one of the
linkages and then we can use the full range of motion at a closer point which
means the servo motor will have more torque to open just one of these instead
of opening two so we can actually swing like spider-man
all right so we've got a pile of weights here to simulate JT's weight and we've got our revised
servo string so let's test it out
oh boy 160 pound lift... I feel weak...
huh. my knot came out.
and my string broke
alright that didn't quite work so well so we've done a few
more changes we actually added a brass fitting over the bolt to reduce the
friction in the rope so let's try it again
holds the weight. No problem. 3,2,1
sweet alright let's try that again to make sure it just wasn't a fluke
sweet
all right third time's the charm if it works I'll be ready to swing from this thing
sweet let's test it out for real this time
I've hooked the first beam which means it's time to swing for the first time
JT if you're watching this I really hope this works
alright that was freaking awesome but anyone can swing once if you really want
to be spider-man you've got to be able to swing multiple times before letting go
okay this is a little unnerving but I'm hanging from two webs the next step is
to release my right hand and I'm gonna swing and then release with my other
hand even though my glove is moved okay here we go three two one
one more swing.
spider-man
all right so swinging like spider-man is just as hard as it looks
everything being said that was pretty cool I did literally hang from two webs and I was
kind of able to swing. big thank you to Pursuit OCR for providing these awesome
air mattresses because otherwise I definitely would have broken something
if you guys want to see this project continue check out JT's channel Built IRL
because I'm not touching this thing again
