Raphael Seghier, Guilaume Cherau, and team have been building SPINO – a POV display that can connect to your phone through bluetooth and play retro games.
Spino uses either 32 or 64 LEDs for the display. Data is transferred via Bluetooth and the PCB connects to the power using a wireless charging module. Retro games such as PacMan and Space Invaders can be played on Spino. They also hacked the Doom 2 code to play on Spino.
This video shows Doom 2 being played on the POV display.
