Check out this moving story shared with us by our friend Caleb Kraft at the The Controller Project:
Forum user KDM shared this interesting device with us. It is a recorder that has been custom built for a young girl. She was born with only two digits per hand, so a typical recorder was out of the question. With this custom device she is now able to play along with her peers. The recorder is often used in school systems, especially outside the US, to teach the basics of music, so I imagine this was built so she could participate with her peers.
KDM constructed this from a normal recorder by hollowing it out on a lathe to make space for the electronics. The momentary switches that you can see poking through the holes send signals to a PIC processor which converts to MIDI. The recorder can be plugged directly into a keyboard which plays the audio.
