Penguin Atmega32 game system
vladutz2000 has published plans for an overclocked Atmega32 based 8-bit game system. Dubbed the Penguin, this project runs the chip at 27 MHz instead of the usual 16 MHz and uses a 128×64 monochrome KS0108 based display along with a speaker and handful of resistors and pushbuttons. The schematic couldn’t be simpler and it, along […]
