While not as low-tech as the Thumb Stadium, the hardware for this handheld PIPER (a recursive acronym for PIPER Is a Portable Embedded Roguelike) console won't outclass the Game Boy, either. The system features a 4 MHz-speed microcontroller, 8KB code flash ROM, 368 bytes of variable RAm memory, and a 128x64 pixel LCD.

Powered by three AAA batteries, PIPER is designed to run a "light" roguelike game that you can program into the system. Pic-Rogue, the first roguelike designed to fit the portable's low memory requirements, features 25 randomly generated levels (six enemies and three traps each), 25 monster types, 13 spells, seven special attacks, and six abilities (e.g. HP, AC, power).

The developer behind the project isn't selling the system but has made available PIPER's circuit schematics and PCB layout/construction, as well as Pic-Rogue's source code. The hobbyist also notes that he or she is redesigning a smaller version of the 12x8x1.5 cm handheld with four times more memory, and might consider selling the custom portable in the future, too.
