enabling the gpio on the beaglebone

Currently in the process of building the hardware for the first beaglebone bufocam. The 1-wire and RTC clock have been mounted on some prototyping board (ebay). Cheapest supplier I found for board headers was rapid electronics - buy the larger ones and cut them down.

I want to add a couple of LED's to the inside of the box to give some user feedback that something is really happening. There are lots of guides already for this;
