The main parts will be:
- Ring Modulator
- 555 pulse generator
- Microphone amp
If I can work it into the project in time:
- A color/light organ (because the Cybermen and Daleks both have a part that lights up when they speak)
The plan for this project is to keep it as low budget as I can. (For those makers out there that, like me, do the best they can with what little they have).
