I'm interested in making a music-playing bike for an upcoming arts festival.
I've seen posts on here about stereos for blasting music from an mp3 player. This is not what I am asking about.
I'm asking about creating a mechanism where notes would sound as the cyclist pedaled and the wheels moved. I've seen versions of this (like the guitar windmill at Makerfaire Austin 2008). I remember talking to an engineer friend about how to make it work years ago, and he said I should look into "ionian harps," but I can't find anything relevant to my project.
Just going to repeat this: This would NOT be for street-riding. I understand that riding this around a campus or road could disturb other commuterse. This mechanism would specifically be for an arts festival where people would be expecting lots of loud music and noisemakers and such from all directions.
