For roughly $250, you too can have this sweet bit of gadgetry based off of the Arduino platform. It is open source, and has some pretty impressive specs. Sporting a rumble pack, lithium ion battery, OLED display, and space for expanson. You can buy the pieces pre assembled, or as a kit. If you get the kit, you’ll see that the controller board has been laid out so that you can solder your buttons and joystick in as either left handed or right handed. The only problem? No games yet.
