Electric motor + diddley bow (loads of noise: sample if you like)

Sounds like an old WWII bomber flying over .

I don't know if this would work but have you tried putting one of those tiny round magnets on the spinning part?

[@jacobsteel]

@@GraemeWolfendale - I’m about to try. Tested my CV to PSU driver today, magnets = stronger effect on the Humbucker/Strings = even slow spins might produce percussive sounds… 🙏 The motor can be controlled by CV.. I’ll post soon…

[@kyletheenigma]

these are spectacular. do you have a site where I could buy any of these devices you've created?

[@jacobsteel]

The lab stand is a VEVOR

Here's how I made the Diddley bow
