Quality wind chimes are not cheap. No matter how much you spend, though, they generally sound the same year after year. If that bothers you, maybe [sensatroniclab] can help. They’ve posted a simple design for a digital wind chime using the Ototo music generator.
The Ototo is reasonably priced and promises to let you make music from anything (well, anything conductive, anyway). Because the Ototo handles all the music production, the only real building part of the project is the wind sensors. The sensors are made with conductive fabric with a marble at the end for weight.
In the video below you can see [Matthew Ward] talk about the device and actually play it like you might a harp. This would be a good school project owing to the simplicity of using the Ototo, although [sensatroniclab] is actually working on accessibility music projects.
One challenge for students would be to make up new kind of sensors. After all, why wind chimes? Why not rain chimes or a hamster-driven instrument?
