Here's a link to the wiring and code: http://www.thingiverse.com/thing:1545926/#files My partner Christy has an awesome profile over here: http://www.thingiverse.com/Christy/about We collaborated closely to design this innovative clock together. A servo motor will drive the large gear, rotating it 180 degrees, and then the large gear will turn the small gear a full 360 degrees. As the small gear spins, the indicator attached to it is triggered by magnetism, causing a tiny metal ball to move smoothly along the surface of the clock.
