If Kickstarter is nowadays best place to find new (or upcoming) toys to dream about, Gameduino is probably one of the most amazing pieces of hardware I’ve seen hosted there. The shield mounts its own FPGA able of 80ies style graphics and sounds for creating old-school, 8-bit video-games, pre-loaded with numerous sprites and set up for easy connection to a VGA display.
Gameduino is a game adapter for Arduino – or anything else with an SPI interface – built as a single shield that stacks up on top of the Arduino and has plugs for a VGA monitor and stereo speakers.
The sound and graphics are definitely old-school, but thanks to the latest FPGA technology, the sprite capabilities are a step above those in machines from the past.
