self powered by turning a crank

Similar projects worth following
no batteries required

This is a three parts synthy, combining the following 


always on when turning (probably 40106)

Melodic keyboard

needs a keyboard of some sort 


with input from dynamo or encoder wheel on crank

will also need a good generator / dynamo - 3 phase brushless maybe?

I didn't say this yesterday, but I'm very happy to see a hurdy gurdy project on here. It's been the instrument I'm most interested in learning (though that interest is still not enough to actually do something about) since I saw Guilhem Desq's Omen video 3.75 years ago. I have an idea for a musical project that I might work on soon, and drones might be a great addition to it, so thanks for the inspiration there!

Another idea: droning drone! A drone (the flying kind) that produces a controllable musical droning sound as it flies.

hey, a good friend of mine Beth Flanagan created an electronic hurdy gurdy a few years ago and did a presentation about it at the Embedded Linux Conference Europe in 2015. She talks about a lot of the "tips and tricks" as well as the "gotchas":

Good luck with the self powering part. You would need to buffer at least some of the energy, because sometimes there are pauses, see e.g. at 0:45:

and power could be a problem for a speaker. Also forward/backward movements are possible, see at 2:13 and 3:47, and faster movements sound different, see 2:53:

so you should measure the speed and direction of the crank.
