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
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!
Step 3: Barrels
Step 4: Barrels attachment
Step 5: Preparing the case for the gearbox
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 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 closed the joystick case, and installed all the mechanism in the Thermos bottom.
Step 8: Arming the gun
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
Step 10: Battery compartment and other plastic pieces
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.
