This hack was recently developed by some students at Imperial College Robotics Society at London. This is a very simple hack that requires minimum piece of hardware. All you need is raspberry pi, FM radio and a bare piece of wire to act as antenna. Just follow the procedures explained at their website:
In fact, it's not just transmitting at the frequency -set using the command : sudo ./pifm sound.wav 100.0 -but also it is radiating at some other frequencies as well. I don't know the reason for this but this event was reported by various students when they used spectrum analyzer on radio frequencies.
Here are the photos showing how I did this project:
There is certainly no need to mount the antenna right on top of the pin, an external breadboard (with antenna attached) would have worked fine.
