World's Smallest Aliens M41a Pulse Rifle Counter Board

A little tight on space in your M41A Pulse Rifle build?

Funds a little scarce?

Well, look no further!

This is the world's SMALLEST Pulse Rifle Counter board!

Measuring just 32mm by 24mm this tiny counter board will fit in any build no matter how tight for space you are.  With the LED display positioned right in the upper-right corner there's nothing to get in the way of your magazine.

This board provides just the basics.  Connect a battery (anything from 6.4V up to 15V, a 9V PP3 is ideal), and two buttons for trigger and magazine, and you're ready to go. The counter counts down from 99 to 95 when a magazine is inserted, and the trigger then counts it down to 00, just like in the movies!

For wiring, the battery connects to the two pins marked + and -, and the two buttons connect between TRIG and COM, and between MAG and COM.

For the more adventurous among you it is possible to re-program the board to do other things, if you have the skills to program a PIC18 microcontroller.
