Introduction: Gattling Gun Cyborg Arm

Picture of Gattling Gun Cyborg Arm
Maker Faire. I couldn't go only with one Cyborg Arm. Nah! I had to go with TWO FREAKING HEAVY CYBORG ARMS!

So, I made the second one. It's like the first one, just changing the pincers for some kind of gattling gun, that spins at high velocity and has a red led, giving the "FIRE" effect.



This Cyborg Arm has two problems:

1. Too heavy. You need the fitness of a sexy Latino gardener for wearing it for a long time. And it's heavier than the first one, so you feel like Hellboy.
2. It has the power of turning its bearer into an evil person. Look at our sweet Carley Jacobson (pictures). Now she feels the hunger for power and mass destruction!

But, still, you can make it for a cosplay, or just in case you want to delight yourself with images of your future robotic empire.
 

Step 1: Materials and Stuff

Picture of Materials and Stuff

I used the following stuff:

All the plastic trash I could get
Corner braces inside L (2in. x 5/8in.)
Corner braces inside L (1in. x 1/2in.)
1 9V battery clip
1 9V battery
1 big and red LED
2 220 ohm resistors
1 damaged small flashlight
1 big Thermos
1 damaged tower fan
1 damaged plastic table set for babies (I used the front support)
1 big electric toy car (I needed the motor, the gearbox and the wheel)
Something with a handle (like a toy iron)
1 switch
1 joystick
1 rectangular keyboard
8 PVC plugs (or any other cylindrical pieces)
black plastic junk pieces
Nuts, screws and bolts
Iron washers
Wire
Superglue (cyanoacrylate)
Cellulose sponges

TOOLS

Dremel Rotary Tool
Power drill
tweezers
screwdivers
scalpel
pliers
Wire cutters
Screwdriver kit
Soldering Iron


And don't forget:

1. If you don't have it, replace it!
2. Use protective equipment (dust mask and goggles)
3. Beware of drilled and soldered hot surfaces
4. Work in a good ventilated area.
5. Always have junk in stock.
6. Have fun.

Step 2: Dismantle Everything!

I took the baby table and I removed the front yellow leg. Then, I took the thermos and removed the bottom (the blue circle) and the styrofoam. From the toy car, I separate the gearbox with the motor and one wheel.

Step 3: Barrels

Picture of Barrels

Using  the power drill, I made eight holes on the bottom of the thermos, and then I inserted the PVC plugs. I fixed these with some superglue.

Step 4: Barrels Attachment

Picture of Barrels Attachment

I took one wheel from the toy car, and I removed the tire. Then, I attached two corner braces to the wheel, and attached it to the center of the barrels. The gearbox axis must attach to the wheel.

Step 5: Preparing the Case for the Gearbox

Picture of Preparing the Case for the Gearbox

I took the case from a joystick (relax! It wasn't from an Atari) and installed the gearbox. The thermos is the main part of the cyborg arm, and I had to install this case on the bottom of the thermos. The gearbox axis doesn't have to stay in the center of the joystick case, but aligned with the center of the thermos, so the barrels can be aligned, too.

I soldered wires to the terminals of the motor.

Using the cutting disc, I opened a square hole on the thermos bottom, for housing the joystick case. Then, I attached a plastic sheet to the case, so later I can fix the case to the thermos (but not yet).

Step 6: Adding the Light

Picture of Adding the Light

I plugged the barrels to the gearbox and marked the exact point where I wanted to install the light. Then I took the damaged flashlight, I installed the red LED, I soldered the resistors in the positive terminal, and I attached the light to the joystick case, using the frame of a small fan. The light has to coincide with the plugs holes, so you can see it when the barrels are spinning.

I connect the LED wires to the motor wires. Remember: red with red (positive, longest LED terminal), black with black (ground).

Step 7: The Handle

Picture of The Handle

I removed the handle from an iron, and the I attached it to the joystick case. I installed the switch, so I can activate the barrels pressing it. I soldered red wires to the switch's terminals, connecting one to the motor/LED red wire, and the other to the batteriy.

I closed the joystick case, and installed all the mechanism in the Thermos bottom.

Step 8: Arming the Gun

Picture of Arming the Gun

I attached the barrels to the gearbox axis. Then, on the the top of the thermos, I added the case from a calefactor (the same one from my previous cyborg arm).

To reduce the risk of scratching parts of my body, I added part of a plastic container in the place where I have to introduce my arm.

Later, I added the leg from the baby table.

Step 9: Covering the Barrels

Picture of Covering the Barrels

There was a lot of empty space between the barrels and the arm case, so I covered it using a plastic sheet from a keyboard and some kind of kitchen cutter I cut in halfs, For the keyboard sheet, I bended it using a heat gun.

Step 10: Battery Compartment and Other Plastic Pieces

Picture of Battery Compartment and Other Plastic Pieces

I found a compartment beween the thermos and the calefactor case, so I installed the battery there. I extended the wires from the joystic case to this compartment, I soldered the battery clip and used a printer pices as a cover for this.

I added some extra plastic parts: one over the babe table part, and a piece of the case from a printer. Then, I covered the LED lens with a tape, to protect it from the paint of the next step.

Step 11: Paint

Picture of Paint

I painted the arm using Krylon Stainless Steel Finish. First, I painted the barrels separated from the arm case. Then, I joined both and painted again.

Step 12: Last Touches

Picture of Last Touches

I added some black plastic pieces (including a telephone case) for decorating. And now, I have TWO cyborg arms ready for action!

Maybe you could cut peces out of the large solid parts to give it a cool openwork feeling and at the same time, make it lighter.

Enriqueto (author)2014-03-17

Brutal! original y resuelto con ingenio, por lo del peso hay que
recordar que en una pelicula generalmente se tienen varios tipos de
"props" del mismo .... este sería el modelo "hero" para acercamientos y
primeros planos porque es el que se ve mejor en cámara ...

M.C. Langer (author)Enriqueto2014-03-23

Muchas gracias Enriqueto! De dónde eres?

patbking (author)2013-11-23

It's so awesome so going to make it

M.C. Langer (author)patbking2013-11-24

Thanks Patbking!

peyton14 (author)2013-10-31

Dude, I have to hand it to you(heheheh, hand) that is one sweet arm. I'd love to make it into a steam punk arm!

andrea biffi (author)2013-09-11

Now you only could make Cyborg Legs (you finished the arms)
;-)

M.C. Langer (author)andrea biffi2013-09-11

LOL! Yes, I will try legs for the next time :-)

Derpy (author)2013-08-16

Could you make me one and send it to me

M.C. Langer (author)Derpy2013-08-17

I can make and sell you one, but you have to pay the shipment.

master hero103 (author)2013-08-14

I think you should make cyborg upper arms with missiles and a laser on the other

darblar (author)2013-08-13

Make is 'shoot' soap bubbles!

M.C. Langer (author)darblar2013-08-14

Not a bad idea!

Edgar (author)2013-08-14

master hero103 (author)2013-08-13

I don't believe in showing my age on the inter-web

master hero103 (author)2013-08-12

Also you should make cyborg spying camera built into the suit

Yes sir, for the next time.

master hero103 (author)2013-08-12

Just kidding I'm making secret agent stuff though

master hero103 (author)2013-08-12

I'm going to make a alliance to destroy you once and for all

BigMrTree (author)2013-08-12

Now that you have two cyborg arms... how about Cyborg legs!! Your stuff is always so amazing!! You have quite an eye for seeing such potential in ordinary objects, another great instructable!!

M.C. Langer (author)BigMrTree2013-08-12

Thanks BigMrTree!! And you are absolutely right, I have to make cyborg legs! :-)

Spyro260 (author)2013-08-12

It doesn't actually shoot:(

M.C. Langer (author)Spyro2602013-08-12

But now you know. And knowing is half of the battle! :-)

Spyro260 (author)2013-08-11

Does it shoot?

M.C. Langer (author)Spyro2602013-08-11

Please read my instructable and you will find out. Thanks! :-)

airsoftredneck96 (author)2013-08-11

All your stuff is freakin cool! Have you tried to make many of your guns shoot?

Thanks! My 3D printed tank launches a missile, and one of my next instructables will be a 3D printed action figure with missiles. Maybe one day, I will make a cyborg arm that launches missiles.

airsoftredneck96 (author)2013-08-11

Sorry, any
