I tore down the breadboard today and rebuilt on smaller 30 row units. I also got an order of ATMega328Ps today too so I prototyped the controller board too (which really, it just the AVR + radio + eeprom).
Didn't hook up the ethernet breakout yet - this part of the project really worries me because it's not the oft-used Wiznet chipset, documentation for this one is a little thinner.
I'm starting on the schematics. Follow along on Github.
