I have an adafruit wave shield and various IR sensors. The wave shields can read and play wav files from an SD card, so I'd like to try wiring it up to an IR sensor to control which wav files are played. Hence it's a harp :-)
Nice. One of the guys from the Liverpool hackspace built himself an IR Guitar (it only had five strings, so calling it a harp seemed to be pushing it a bit :-) at the recent Interface Amnesty event. There's some low-quality video of it at http://qik.com/video/3013203?page=2
He was using it as a MIDI controller, so it will be interesting to see how it works with a wave shield
Nice example - I was thinking of using just one IR sensor, and using the variable distance measurements as a trigger for playing different sample files...
also: I haven't tested the wave shield yet, but I'm guessing that it doesn't allow multi-channel sound output, so will only process and play one .wav file at a time - so that's an interesting design constraint -
plus, I imagine that therefore there might be a lag issue - which could also impose interesting design constraints...
A generated audio signal (synth) is probably easier for a harp like instrument, but if you put the range finder sideways you could make air drums! Each point along the line triggering a different drum sample.
