Sub-Etha Software was originally established in 1990 to market products for the Radio Shack Color Computer and Microware’s OS-9 RTOS.
Today, we mostly features articles on Arduino, Raspberry Pi, and retro computing topics such as Microsoft BASIC. Some of the more recent projects have included a $10 RS-232 WiFi modem, a low-cost serial port multi-voice sound player, and FPGA home computer emulation.
In addition to electronics tinkering, we also cover Halloween projects including low-cost video players, triggered audio devices, and DMX lighting.
Explore the site, or drop by our booth at the next Chicago CoCoFEST! and see some of these projects firsthand.
