The Uzebox is a retro-minimalistopen sourcevideo game console design. It is based on an AVR 8-bit general-purpose microcontroller made by Atmel. The particularity of the system is that it uses an interrupt-driven kernel and has no frame buffer. Functions such as video sync generation, tile rendering, and music mixing is done realtime by a background task so games can easily be developed in C. The design goal was to be as simple as possible yet have good enough sound and graphics while leaving enough resources to implement interesting games. Emphasis was put on making it easy and fun to assemble and program for any hobbyists. The final design contains only two chips: an ATmega644 and an AD725 RGB-to-NTSC/PAL encoder.
Since its inception, the Uzebox design has been commercially implemented as the Fuzebox Do-It-Yourself kit and the Uzebox AVCore, a fully assembled unit. In 2011 two further Do-It-Yourself kits released - the Uzebox DIY kit  and the EUzebox DIY kit with SCART output for the European market.
