The Tiniest Video Game

As we read [Adam]’s writeup for an extremely tiny video game system through coke bottle glasses, we’re reminded of the countless times we were told that sitting, ‘too close to the Nintendo’ would ruin our eyes. We’ll happily dismiss any article from a medical journal that says there was any truth to that statement, but [Adam]’s tiny video game system will most certainly hurt your eyes.

A few years ago, Atari sold keychain-sized joysticks that contained classics such as PongBreakout, Centipede, and Asteroids. [Adam] apparently ran into a cache of these cool classic baubles and immediately thought of turning them into a stand-alone video game system.

For the display, [Adam] used a CRT module from an old Sony Handicam. These modules had the right connections – power, ground, and composite video input – to connect directly to the Atari keychain games. The result is a video game that’s even smaller than a postage stamp. The picture above shows the tiny CRT next to a 25mm postage stamp; it’s small by any measure.

    1. I have one from JVC with only 5 wires that has been sitting around for about 2 years now, and I can’t find a pinout for it anywhere! I was originally going to make a pong or tetris portable with the arduino-tvout library

    2. Disassemble the entire viewfinder. They often have stuff like LEDs put in. I have one with 6 wires, and after all it’s GND, +5V, Video, LED 1, LED 2, LED GND or something like that. Had it hooked up to my Commodore 64 at a time…

      Btw while I’m at it… I built TinyPONG on a HD44780 character LCD in a single 5*8 pixel char cell. And that was in 2010.

  1. The lenses on these viewfinders make great inspection magnifiers.
    With the extra wires, one is often the on-screen stuff. Establish ground then look for a ‘lytic with a plus rating and make it hot and see if it lights up.
