One of our younger hackers just finished off this awesome Instructable on his flexible 14 x 15 pixel, pong playing t-shirt!
[Spencer] has been working on this on and off for the past year, and finally debuted it at a few Halloween parties last month — it was a hit. He’s made the screen out of RGB LED strips, cleverly soldered together into a large flexible panel of 14 by 15 full colour pixels.
An Arduino Mega takes care of the logic to run the game, which [Spencer] wrote all himself! There’s also a cleverly designed controller using a slide-potentiometer and single button. To play back, the computer AI uses about 15 lines of code, which for pong, is more than enough. He’s also made the whole thing removable so you can still wash the shirt. Finally, the batteries and the “Magic Box” go into a pocket for simplicity’s sake.
If you’re interested in making your own, he also has a Github repository of everything you need. Stick around after the break to see a demonstration of the shirt by [Spencer] himself!
