Summary
Niftymitter is an open source short range FM transmitter based on the open source hardware design by Tetsuo Kogawa.
Version 0.24 is designed to be housed within a ~1mm card body (shirt card), 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.
The new version solves many of the problems in v0.22/0.23:
- Full assembly instructions on instructables.
- Artwork/info added on housing.
- Stereo/mono conflict resolved - can now accommodate stereo and mono plugs.
KNOWN ISSUES IN v0.24:
- circuit box slides around when switching on/off or plugging in.
- PP3 power lead needs better access to battery tray.
