Lazerclock!!

The Lazerclock!! is my project designed and built for Stanford's ME203 class. It's a real clock. It uses a 5mW 405nM laser to write the time on a photosensitive vinyl. The arms are controlled by two (hidden) servo motors, which are in turn controlled by an Arduino Pro Mini. The whole casing is machined out of quarter-inch aluminum, and the logos on the front/back are made with glow-in-the-dark powder coating.

Many thanks to the designers of plotclock.
