No sooner did I write my last entry that I saw a flash out of the corner of my eye and the send/receive light on the board started going nuts.

Despite the large rubber feet on the protoboard keeping the wiring away from the tin, it looks like I just shorted across something near the red pin of the RGB led. That side of the LED looks dark and I can't get red to work.

Time to replace the LED and better insulate the underside of the protoboard.
