Raspberry Pi-rate Radio - Create you own radio station
All you need is a $35 RPi and a length of wire for the antennae. Add you music to a memory card, select your frequency then tune in
It uses the hardware on the Raspberry Pi that is actually meant to generate spread-spectrum clock signals on the GPIO pins to output FM radio energy. This means that all you need to do to turn the Raspberry Pi into a (ridiculously powerful) FM transmitter is to plug in a wire as the antenna (as little as 20cm will do) into GPIO pin 4 and run the code.
