The Trimphone is a modified telephone that includes a web cam in the earpiece and an Arduino in the base. By dialing different numbers the user can select different video loops that are mixed with the live feed from the web cam. [Thanks Lukas]
The rotary dialer circuit and Arduino code are pretty simple. Dialer works on principle of interrupting current: dial 7 and current is interrupted 7 times – this is counted in Arduino and the number is sent via serial to whatever application listens. Webcam is connected via USB and microphone through standart mic jack.
