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]

Did I miss where the clock runs via the pic and the stepper motor?
It’s working the whole time, watch the beginning again.
It might help to note that it only ticks once every nine seconds, presumably because it doesn’t have a second hand.
If only I could push 2 buttons and manually control time! :)
Not only is this clock cool, I learned the word decrement.
