Step 1: Materials
1 Mr. Potato Head hat
1 cap from a phone horn
1 camera len (I use one from a damaged security camera)
6 butterfly clips (I use 8 because I want an octopod Mini DOR-15)
1 toy motor
1 Playstation joystick motor eccentric weight (or you can make your own eccentric weight using a plastic or metallic piece)
1 Big red LED.
2 LR1 batteries
1 LR1 batteries holder
2 iron pieces
red and black wire
screws and bolts
Dremel Rotary Tool
And don't forget the classic building rules (plus one):
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.
Step 2: The Hat
Open a hole in the front of the hat and insert the len. It has to fit by pressure. Use superglue if it doesn't fit exactly.
Step 3: The Legs
Fasten the clips using screws and bolts.
Open an entry on the front of the cap for accommodating the len of the hat.
Step 4: Electronics (LED)
Open a holeon the phone cap. It will be for the switch.
Insert the big red LED into the len. Solder wires and a 220ohm resistor.
Step 5: Electronics (motor and Batteries)
Attach the motor and the batteries to the central screw. Use the iron pieces.
Connect the motor wires to the LED and batteries (remember: red wire = +, black wire = -)
Test the motor spin and put together the hat and the cap.
