PING! Augmented Pixel Videogame System

Niklas Roy has built an addictive-looking 70’s-style videogame system that is “controlerless” like an Xbox Kinect, yet charmingly low-rez like Pong.

What I found interesting when I developed this game, is, that it could have been made already in the seventies. The technology that I used for it is (in a way) similar to what Atari used for the first Pong. It becomes even more awkward, if you think that the electronic components for capturing and evaluating a video signal are cheaper than the rotary game controllers that Atari used.

The game is programed with AVR-GCC on an ATmega8 microcontroller that runs with 16MHz. The controller gets basic videosignal synchronisation information from an LM1881 sync separator that triggers two hardware interrupts. One for a new image, the other one for a new line. The controller evaluates the brightness around the pixel (/ball) via its comparator input. Drawing the white image overlay is realized with a simple pull-up resistor in the signal line.

Niklas has shared the source code here. Now, please give us a schematic, because I want to build one!
