Built by Alan Parekh, this DIY gear clock isn’t just eye candy, it “uses a PIC 16F628A microcontroller to keep track of time and a stepper motor to physically move gears to represent time.” Video after the break. Click here for first picture in gallery.

This microcontroller has an internal oscillator however an external 20MHz crystal oscillator is being used since it will have to accurately keep track of time for weeks and months.
