[Andy] stuffed some more RAM onto an Arduino Mega and his three-part walk through on the design , construction , and software is a great read and one of the more ‘hard core’ Arduino builds we’ve seen. The build is centered around a 512K × 8 SRAM module [PDF warning]. Because the RAM is divided up into about 512,000 chu...
