AC-1 Audio Computer - Overview

Hardware overview of my AC-1 audio computer. It is an embedded system serving three purposes: 1. Audio equipment power on/off control (locally and through LAN) 2. Remote sound card for hosts in my LAN 3. Media library / network attached storage After some problems with the mode switch and operating system, I redesigned and reworked the control circuitry, and recombobulated the software... Simpler, more reliable and more sensible than before. The cloorful light flashes on the HDD enclosure is just holiday lights above my bench. I probably should have turned them off before making this video...
