RBox: A DIY 32-bit game console
26. June 2010 - 13:50 — adminThe RBox is a game console that is simple enough to build on the prototype area of a LPCXpresso ARM dev kit. You need just a crystal, a few capacitors and resistors. It uses the smallest and cheapest 32 bit CPU to generate 3D graphics and sound.
