A big project I finished about a year ago, a centerpiece in my portfolio. Made from A combination of Sintra, MDF, steel, fiberglass casted parts, and found materials. The lights are powered by arduino and are hooked up to a raspberry pi running a Pure Data program that converts my voice using a ring modulator patch into the Dalek voice. The patch also controls the brightness of the eye light depending on the volume of my voice. There Is no moter inside, It's powered like Fred Flinstone's car, foot shuffling.
Need to re-photograph this, it's been updated alot more.
