Introduction: Gattling Gun Cyborg Arm
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
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 rectangular keyboard
8 PVC plugs (or any other cylindrical pieces)
black plastic junk pieces
Nuts, screws and bolts
Dremel Rotary Tool
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
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
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
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
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
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
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
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
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
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
I added some black plastic pieces (including a telephone case) for decorating. And now, I have TWO cyborg arms ready for action!
We have a be nice policy.
