Cocktail cabinets are an excellent way to cram a two-player arcade into a small package. DIYer CircuitBeard shows off his build, which uses a Raspberry Pi as the brains. It's a looker.
The cabinet is made with cheap MDF, then covered in vinyl to give it a vintage look (seems like contact paper would do this job fine). From there, the arcade sticks are wired in, the screen attached, and the Raspberry Pi is loaded up with RetroPie for emulation.
You'll find the bulk of the guide for how CircuitBeard built the cabinet over on his site, though its sadly lacking the design files for the cabinet. Still, it's packed with a ton of other info, including how to get the Pi to play nice with the display and the arcade sticks.
