The Java Propeller Clock by Don Zehnder!

This applet simulates a very cool electromechanical device I built. The hardware is based on a Microchip PIC16F84 or PIC16C84 microprocessor and just a few other components.
The JAVA code for this applet and a discussion of specifics about this applet

This is the actual clock that I built some time ago based on Bob Blick's original propeller clock project.

A version which was based partly on my modifications to Bob's clock was made by Luberth Dijkman
Luberth's site has a link to the assembly language source code that I wrote for my version.

NEW! An much improved BLUE LED version that I built along with schematics and source code
