The staff and supporter MAGFest 11 badges have a touch sensor on them, which is neat and all, but I was curious if they could be re-purposed as a funtenna.  The answer is yes.

I've used the two large touch sensor areas on the board to act as an FM transmitter.  They are using OC1B's outputs and everything's hooked to the system clock through a PLL x8.
