PIC-TOCK PENDULUM CLOCK by John Becker, EPE Technical Editor

Everyday Practical Electronics, Sept. 1996
------------------------------------------

This amazing PIC16C84-based design relies on persistence of vision to
'write' the time in thin air! An l.e.d. array is set into a
swinging pendulum and displays a 24-hour clock.
