Relay Internet Radio to FM With Raspberry Pi
Internet radio is great, but you need an Internet-connected device to listen to it. If you have an old radio and want to listen to some tunes, Make will show you how to relay those FM stations using your Raspberry Pi.
You will need a Raspberry Pi along with an Adafruit FM transmitter (you can also just hack your own antenna, no purchase required with this guide ). When you’re done, you should be able to transmit up to 30 feet. For most of us, it is certainly easier to simply connect our devices to a stereo system, but this is not always possible with older equipment.
