Add a video connector to the chumby One

Buy an RCA extender cable, with at least one male end. Cut to the length you desire the pigtail to be. Typically, you want to use the male plug half because your video equipment will have a female jack, but of course this may vary depending on how strange your video equipment is.

Take the cut end and strip the wire back, and solder according to the following diagram:

To access this part of the circuit board, you actually do not need to remove any screws. If you are very careful, you can use a flathead screwdriver and insert it into the gap between the front bezel and the bottom plastic, and pry the bottom plastic up. You'll have to work it up by gapping the plastic at both ends of the seam between the front bezel and the bottom plastic, since there are two friction locks on either end of the seam. The piece just snaps into place, there are no screws that hold it down. If you're not careful, the worst you will do is break the retaining tab on the bottom plastic, which means that your battery compartment won't be held snugly in place when you put it back together again.

You'll need to mod the firmware to activate the video out. This is left as an exercise to the reader.
