When the first Raspberry Pi, it was very exciting time. So I designed a PCB for RPi with arduino connectors and power supply section. I ordered 10 on them. After soldering the headers and stuff I tried mounting on the Rpi. Turns out I got the profile of the PCB wrong around the video connector. Here is the failed pcb.

The arduino headers were good. So I figured I'd use this as an Arduino shield and solder screw terminals on proto area.
