Gear clock based on PIC16F628A
Current time is displayed as hours and minutes on two big gears which are made out of wood. They are turned by stepper motor which is controlled by PIC16F628A microcontroller that keeps track of time. This clock is adjusted by turning big gears by hand or by two push-buttons on the electronics board. Source code for PIC is available for download on project page, for all those electronic woodworkers.
