I can’t seem to find my inspiration for this (I blatantly ripped off someone else’s project) but I thought I’d post it. I work on lots of old computers, and frequently when I’m testing a whole lot of motherboards I find it useful to have this header made out of a bit of pcb, a panel mount db9 connector shroud, and an old pc switch harness. There is no circuitry, nothing complicated or even innovative in this project, it’s compact and I find it useful. (photos courtesy of my HTC dream [G1], new camera on the way)
