MAKE photo pool member Shufflehacks writes “I built my own radio-transmitter for my Shuffle, I nicknamed it “iMouse”. It works quite easy, there is a power switch on the bottom to turn it on. Just press play on the Shuffle and tune your radio to the right frequency. The range is about 100 to 150 meters.(500 feet) Now I can enjoy my Shuffle on my car stereo.” Link. It’s made out of an old mouse, excellent.
