Hi, I took a couple of pictures on two PCBs that I made with gEDA and PCB, figured someone might be interested to see how they came out;

It was easy enough to cut the panel myself into the two circuit boards. The functions of the daq_conn board is to act as a connection box for a data acquisition board to allow connecting several DSUB connectors into one DAQ board. This is basically just a bunch of connectors. The second design is for discharging rechargeable batteries with a variable load while measuring the discharge current. There are also some watchdog functionality on that board later board. I found a few issues while assembling these PCBs, mostly related to footprint problems. The only problem that I have found so far related to the symbols part of gEDA/PCB is the RADIAL_CAN 200 footprint that I used for the electrolytic caps. The finished hole using this footprint is very small and made it hard to mount the caps. Not sure if this footprint was intended for those kinds of caps though, but if it is it should have larger holes and also an indication in silk which pin is the positive of the polarized cap. Another thing I would do differently next time is to increase the size of the text on the silk screen layer. It comes out readable, but it could be larger to make it easier to see. -- Daniel Nilsson
