An FM transmitter is handy for all kinds of things. With it, you can broadcast to pretty much any device in your house or to other people nearby at an event. The process takes about an hour to complete. You’ll make a simple FM transmitter from a wire and make a disk image for the Raspberry Pi. Then, you’ll simply add your favourite songs to the Pi and you’re all set. Head over to Make for the full guide.
