Hello,
I've been working on a couple of projects that both require a countdown timer. So, instead or reinventing the wheel every time, I made a simple "countdown-timer-on-a-chip" project - a program that turns a PIC16F690 (or similar) into a nice (almost) self-contained timer - all you have to do is attach some buttons and a pair of two 7-segment LED displays.

Also, just for fun, I made a small JavaScript "simulated timer" and put it on the site - you can play with the timer and see if this is what you need even before looking at the code or schematics.
Maybe somebody will find this thing useful for something.
Regards,
- Alex
