Turn Your Raspberry Pi Into An FM Radio Transmitter

This simple hack turns your Raspberry Pi into a powerful FM transmitter! It has enough range to cover your home, DIY drive-in movie, a high school ball game, or even a bike parade (depending on the stragglers).
PiFM software not only boldly enhances the capability of your Pi, but does so with nothing more than a single length of wire. This hack starts with the absolute minimum you need to run a Raspberry Pi — an SD card, a power source, and the board itself — and adds one piece of wire. It’s the coolest Pi device we’ve ever seen with so few materials.

This looks like something interesting to try. Please note that running an unlicensed FM transmitter over a certain power level is against the law.

Yes, this is my law degree talking. The FCC has a nice page on low power radio stations that you may want to take a look at.Powered by Hackadelic Sliding Notes 1.6.5
