To here some crazy robot and pitch shifting action check out the file posted below.
Step 1: Go get stuff
- And IKEA clock body
- An adjustable fluorescent desk lamp
- A HT8950 voice modulator
- A PCB
- An 18-pin socket
- 4 SPST buttons
- Condenser mic
- Parts for the circuit (see next step for details)
- 2 1/8" audio jacks
- A power source
- Misc hardware
Step 2: The circuit
Then solder the circuit onto a PCB, temporarily omitting things like the microphone, audio jacks and switches. This will be added later.
You can test to make sure the board works by adding extra hookup wires for the audio jacks and microphone and connecting them through a breadboard.
Step 3: Get bendy arm
Don't remove the lamp wire from inside the arm. You will need this to hook up your microphone. Therefore, don't trim it too close.
Leave the mounting bracket still attached at the bottom of the arm.
Step 4: Bracket stencil
If you happen to have an awesome Epilog laser cutter like we do at Instructables than you can use that to cut out the pattern onto a piece of tape. If you don't, an Exacto knife will do.
Place this pattern onto what you feel will be the back edge of the robot voice machine.
Drill out all of the holes with a power drill.
