Do you know you can make your Raspberry Pi play your favorite music over an FM radio with a very little effort? Yes, all you need to make this FM radio transmitter is a Raspberry Pi, an SD card, a power supply, and a small piece of wire to serve as antenna. You can load your audio files into the SD card and choose your transmission frequency in the commercial FM band. The PirateRadio.py python script generates frequency-modulated radio waves on the Raspberry Pi GPIO pin 4, which are injected into air with a short wire connected to it.

This project describes an Arduino-based FM transmission using the KT0803K Digital Stereo FM Transmitter Radio-Station-on-a-Chip. The KT0803K device is designed to process high fidelity stereo audio signal and transmit modulated FM signal over a short range. It features an on-board 20-bit audio ADC and supports standard I2C interface for frequency setting and power control.
