The classic pong game. Two players. Press the buttons to move paddles up/down. Ball bounces back and forth. If you fail to catch it, your opponent gets one point. Score difference is showed with blue LEDs. Blue LED = lead by one point. If you then win another point, you win the game, and your player number (“1” or “2”) is displayed.
Bonus feature – Dual boot: When powering up, you have to press one of the two rightmost buttons. One of them starts pong, and the other one starts … that’s right: The alphabet! You can then scroll through the alphabet by pressing the buttons. Exactly why this game of pong also contains an alphabet, is a mystery whose answer is lost in the mists of time. Or something like that.

How it works
The LED dot matrix is driven with time multiplexing. The columns are displayed one by one in rapid succession, giving the illusion that they are all lit at the same time.

Laser video projector
A 16×16 20-30fps monochromatic(red) binary(no greyscales) digital video projector.
Made by Håkon A. Hjortland (programming, construction), Alf Storm (animation), Håvard Moen (AVR know-how, construction help), Ståle Kristoffersen (help with mirrors) and with some help from others.
Original idea (to use laser and rotating mirrors to create a video projector) comes from an article in a science magazine (Illustrert Vitenskap) some time ago (no idea which issue).
