Alan Parekh of Hacked Gadgets made this really nice looking gear clock using a PIC microcontroller, a scavenged stepper motor, and a bunch of wooden gears that he cut out on a CNC router. The concept is pretty straightforward, however I really like the clear design, where each part is a functional piece of the clock mechanism. You’ll never have to wonder what is inside this thing that makes it tick! [via Hacked Gadgets]
