After seeing the HaD post regarding DirtyPCB, I updated the design of the single chip computer (added a reset button, removed the jumper parts, added a capacitor across the AVR supply pins, moved some components closer together etc as shown in the PCB layout below) and sent the files to DirtyPCB. I am currently awaiting the arrival of the PCBs.

Hi Dan,

I got all the components for the PCB v0.2 I got for you on Ebay. I would need the circuit diagram and the firmware for this. Thanks!

  Are you sure? yes | no

Hi Radu,

I sent a copy of the schematic with the PCB and the firmware for the ATmega 1284P microcontroller can be found at the "Code (AVR Sketch)" link on the left hand side of the project page.
