A hacker called [Sprite_tm] AKA Jeroen Domburg built his own teeny, tiny Raspberry Pi-based MAME cabinet using some laser-cut plexiglass, some custom controls, and a eeny, weenie 2.4-inch TFT display. The best part? The cabinet even has a small OLED marquee at the top that shows the current game in play.
The instructions are pretty hardcore and involves tweaking jumpers in order to make the TFT talk to the Rasberry Pi’s onboard graphics chip. While he could have just run a fat HDMI cable out of the thing, it’s impressive that he went out of his way to reduce nearly everything to microscopic size.
