Big Guns...
The tank guns I was planning on using on my mech Gold Rush were just not cutting it for me. Problems included gear skipping and motors burning up. So I was forced to ditch them and went for something a bit bigger.

MechController v1
Spent some time working on the micro controller board that will be going into Gold Rush.
Its a super simple board based around the AVR ATMEGA 644 device. It features only the connections needed for an ax-12 based mech. 5 Ax-12 ports for the four leg and a turret lines, four pin header to attach an xbee explorer board, two three pin headers to digital IO to control dual gun circuitry, separate screw terminals for logic and motor power and an ISP header for programming.
I added 'Faux Silkscreen' by printing out and gluing a sheet of paper with the parts layout and labels onto the ugly fiberglass board.
