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.
Step 5: Control Panel
If you don't have an awesome Epilog laser cutter than you can get the same effect with a jigsaw and a power drill with appropriate size bits.
Place the plastic clock face upside down inside the clock body and then rest the yellow piece snugly on top of it.
Step 6: Buttons
Step 8: Microphone
Step 9: Drill some more holes
Step 10: Plugs
Step 11: Mount the circuit
Continue passing them through the clock body until they are out the back of the case. Twist them together to tie the board in place.
Step 12: Glue
Step 13: Wire it up
Wire the power to the power wires and the audio out out jack to the audio out wires.
