In this chapter, Bogdan is building the Mandalorians Jet Pack.
Welcome to Chapter Five of our Mandalorian series.
Over the past month my team and I at Hacksmith Industries have been
piecing together our very own Mandalorian suit.
In Chapters One through Four we built the Flamethrower,
the Blaster and Spear,
the Helmet,
and Grogu's preferred method of transportation. His floating cradle.
We're halfway to the epic finale where I will don the suit for the first time
and put it to the ultimate test.
You definitely don't want to miss it!
After four chapters we've decided to get Ian in on the action.
So in the next chapter he'll be calling on his experience from the early days of the channel
working on batman builds.
The grapple gun is near and dear to his heart and if you want
that video is available early as in right now exclusively to our members!

We saw a lot of you guys talking about this t-shirt in the comments below
so I'm excited to announce that we've actually released a limited edition Hacklorian t-shirt!
Just visit hacksmith.store to get yours before they're all gone!
When dealing with science fiction there are obviously some things we just can't do.
As a channel we've made a ton of episodes attempting to fly like Iron Man.
I even had the opportunity to travel to California
and take Richard Browning's jet suit for a quick test.
But unfortunately a real working jet pack just isn't in the cards for us...
Yet.
Especially one as compact as Mandos.
But the suit just wouldn't look complete without this awesome tech strapped to his back.
So we're still gonna push forwards, and I'm sure we can find some way to work in a bit of fire.
And of course his missile.
There's no one I trust more when it comes to jet engines so Bogdan is going to take it away.
We need to find a way to fit all these components and parts inside our Mandalorian suit.
We have the power pack for the flamethrower,
the speed controller and batteries for the grappling hook.
As well as the Arduino that controls the entire suit.
The best place to hide it is going to be in the jet pack
because it is essentially just a backpack.
We also need to make room for all the jet pack components themselves
and that my friends is a lot of parts!
You know one of the most rewarding parts of growing Hacksmith Industries
is building an amazing team of talented people to create projects.
Plus we have a ton of fun along the way.
That's why I love playing AFK Arena and I've played AFK for quite a while.
I've built up an exciting and powerful team of heroes from seven unique factions.
The strategies and adventures with these heroes are endless!
AFK has all the classic RPG elements and doesn't require a huge time investment.
Perfect for when i need a break from building armor.
You can collect over 100 heroes for free!
I wish my team would work for free.
Anyway, they look amazing.
My favorite hero is Muriel the Burning Light
because she's a freaking fire sorcerer and you know how much I love fire.
I have my dream team, but what's yours?
Download and play AFK Arena during its anniversary and get 100 summons and one special gift code.
This bonus is unprecedented so you definitely don't want to miss it!
So what are you waiting for? Use my link below to build your dream team with 100 free summons today.
So what are we looking at here Bogdan?
So this is the backing plate for the jet pack and I'm kind of thinking to mount the
speed controller somewhere in the middle since it's the largest component.
And then the batteries uh kind of fit just on the sides there.
The control board the Arduino can go right in the middle, and that clears up space on the sides
because on the actual jet pack he's got these two cylinders which uh we can just
you know substitute for our flame thrower components.
Flame thrower, nice
Yeah
So these will fit right there.
Probably get some hose clamps that are easy to remove so you can take these in and out.
And then the only other thing is the two valves for controlling
the flow.
Okay so those will go up there.
Awesome, and how is this going to stick to my back?
I was thinking straps or something.
I'm going to be integrating this kind of harness thing into the costume.
Okay.
I think what we can do is basically almost make an interface plate off the back
that your jet pack thing can quickly be attached to.
Because the problem is Mando doesn't wear the jet pack like a backpack
so it's literally like floating off of his back.
So I'm thinking maybe add some mounting holes up here
and then use some kind of quick clips or some wing nuts or something to secure it.
And then for the grappling hook components the speed controller and the batteries
we're going to want to be able to use the grappling hook Ian's designing separately
so maybe we could make this modular,
as a sub-assembly that you can actually install under the jet pack
or remove from the jet pack in case we want to use it just in
a regular backpack or whatever else when we're doing that test.
Yeah that should be no extra effort.
I know you said you don't want it to fly, we should at least try
like we got the jet engines we might as well see what it would take to do that.
Well let's take a look.
Okay so we got about 27 kilograms of actual thrust out of this engine
um let's see what this entire thing weighs.
Eight and a half kilos.
Okay and you weigh how much?
About 65 kilograms right now.
And then the armor?
Probably about 20 kilograms.
And Ian's grappling hook winch that's probably another 12 kilograms.
And uh the flame thrower...
Alright so what's our weight budget?
112.5 once he finishes the calculator
Plus about 112 and a half kilograms let's just round that up to 115.
And we want about a 70 percent throttle ratio.
It's about 165 kilograms of thrust that we need divide that by 27 kilograms per engine.
Okay so we need about six jet engines.
Theoretically if you had two in your backpack one on each leg and one on the arm.
You know what that reminds me of?
Richard Brownings gravitys jet suit.
Yeah we'd actually need more jet engines than them because they only have five.
Okay so I guess the jet engine and trying to fly is probably not very practical.
Can we at least make this look more like a jet pack?
Yeah so what I was thinking is in chapter one,
we had these blowtorch nozzles and these just run on propane,
we have propane on the system so that's not an issue.
Fairly easy just attach these to the bottom and the flame looks exactly like the one in the movie.
In season two of the Mandalorian we see the jet pack fly by itself
where the jet engines actually have thrust vectoring not unlike a SpaceX starship.
Right.
Could we do something like that?
Yeah I think so.
A pan tilt mechanism for these will be fairly simple.
Well let's do that.
Cool.
So I'll get to designing this.
I'll finish all this up and I guess I'll get Ben to design a pan tilt mechanism for this.
Let's make it real.
Awesome, let's do it.
Thrust factoring is much simpler than it sounds.
Any engine applies a single force in one direction.
What thrust vectoring is is pivoting the engine to
change the direction of the force to allow you to steer.
In our case we won't actually be flying so we don't need to steer
but we still want it to look cool just like me...
I bought the simple servo pan tilt module for 20 bucks online
and I need to go into SolidWorks and design
a mounting bracket to mount this gas nozzle to this servo.
Let's hop into SolidWorks.
In order to mount all the pieces we first need to drill all the mounting holes.
The holes are done now it's time to bend it to its final shape.
Next up, the speed controller and batteries.
This is the mounting plate that James asks for to make the components removable.
Pro tip for easy wire management lots of zip ties and flush cutters
to make sure that the zip ties when you cut them don't cut you.
This goes right here.
Before I go any further on mounting I'm going to build the covering plate
as well as the two tubes that hold the flame thrower components.
While Bogdan works on the jet pack I'm going to be designing a PCB.
It's going to control the thrust vectoring nozzles the whistling birds the flame thrower
the missile and it's all going to interface with the button pad I made back in chapter one.
I'm using Altium designer.
You can take a closer look at this PCB using Altium viewer.
Let's get to it.
Throw these servo mounts over here.
Alright this is looking pretty good.
It's a good thing I added all those extra buttons because this PCB has a lot of outputs.
If you want to learn about our design check out our schematic at maker.io.
PCB's are still something we outsource and there's not a better
faster more affordable place to go than JLC PCB.
They offer great boards at a quick turnaround.
The cover will complete the jet pack's look.
The jet pack cover is the most complicated piece of this build.
Multiple angles and different shapes.
If I don't get this right the whole project will suffer.
And that's a 50 degree bend.
So that's going to go this way.
That's everything.
Let's go weld it.
That's the backing plate.
Next we need the round tubes to hold the propane, the fire extinguisher and the rocket.
Now we just have to roll them similar to what we did with the flamethrower gauntlet.
Time to weld.
Let's do this one now.
These tubes are done now and I've made a duplicate in order to hold the propane tank as well.
Next what we need to do is attach these caps on the end to hold the propane tank
and the fire extinguisher tank from falling out.
Then we're going to weld on this bracket here which will
actually hold the solenoid for activating the flame thrower.
But before we get that mounting bracket welded on
we have to first make a cutout for this filling port here.
Alright.
We've got the fire extinguisher tube.
We've got the propane tube.
We've got the rocket tube and the backing plate, I think we're ready to join everything.
Now the side tubes.
And there we go, one fully welded back plate.
Next up we need to 3D print some end caps for the top of these.
Let's get those going.
Alright this thing is looking pretty good.
There's still a lot of work to do
but before I get to that I'd like to make sure it fits on James's harness.
Hey James this thing's ready for test fitting.
I just finished making the plate for the harness so let's see if they go together.
The jet pack will sit on this kind of hook
and then attach to those two bolts and it'll actually be basically floating off my back
because this is actually gonna be
inside my costume so the only thing coming out of the costume
will be those two bolts and that hook which should look really cool.
Theoretically this should just be able to fit right onto those two hooks.
And then right onto those bolts.
And I've got the wingnuts over here.
Wow that is pretty heavy.
There you go.
How does that feel?
I think it works.
I've just put together these two connectors which are going to route propane
to both of our nozzles as well as the flame thrower.
The propane comes in here diverges into these two hoses here into these two valves
and that's what powers the two nozzles.
And then there is basically a switch here so we can turn on and off the flame thrower
where this nozzle connects to.
And finally everything connects to Caleb's PCB.
Okay I'm done with this for now.
Next up we're going to add some more decorational pieces to this plate over here and here.
Time to put together the flame thrower mechanism.
Time for the final touches.
I told you we'd get fire in there somehow.
After five chapters we're halfway through our Mandalorian series.
We still have a ton of amazing content coming your way before the epic finale.
And in Chapter 6 Ian will build Mando's Grappling Gun.
