[Nathan] got his hands on a chipKIT Uno32 development board and wrote a Pong sketch that you can play with a VGA monitor. We love the hardware that makes this feel very much like the classic.

[Nathan] took this boombox and outfitted it for Bluetooth streaming. He took a Motorola DC800, which is meant to make headphones wireless, and connected it to the stereo inputs.
