Niftymitter is a short range FM transmitter based on the open source hardware design by Tetsuo Kogawa, housed within a cardboard body, with a variety of options for hacking. The transmitter is tiny and handy for small scale radio broadcasts, building a distributed PA system for performances, linking your personal audio player to your car radio, or for general audio experimentation.
