This week I built the bridge board and two node boards. Milling and stuffing the boards went smooth. While stuffing I finally realized that the rounded trace should be matched with the dot on the microcontroller. The make file for the bridge board ran smoothly after moving to a long term release of Linux. Running the make file for the nodes was a bit more challenging. The first problem was, how to connect all of the boards, I accomplished this by trial and error finally finding that the node board must be connected to the fabisp and the bridge setup. I tried running Arduino on Linux and received the error “serial port ‘COM1’ not found” I tried to change the serial port under tools but it was greyed out and unusable, unable to get past the com 1 error, I moved to a Mac which solved the problem. All the boards worked well after a small soldering mistake was fixed.
