Retro gaming enthusiasts take note: this joystick is what you need to play any Atari gameon the original console. It plugs right into the original console hardware and removes the need to choose the joystick, paddle, or keypad controller separately. You just leave this puppy hooked up and move your hands to the set of controls used on each game.
[x2Jiggy] built the thing from scratch. The enclosure is a wooden box from the craft store. He holds it closed with a couple of magnetic latches like you might find on old fashioned kitchen cabinets. The buttons of the keypad are mounted on a chunk of protoboard but he did take the time to give it a coat of matching paint so that it doesn’t look out of place. Inside you’ll find some more protoboard and point-to-point soldering to complete the rest of the connections.
You can see a fast motion video of the build process after the break. This reminds us of the universal controller built for Project Unity.
