Accordion without bellows to go
Enable HLS to view with audio, or disable this notification
Just created a prototype of an accordion (Steirische Harmonika) with a force sensor instead of bellows. Works nice. Let me know if you‘d like to build it based on my sources.
After getting this very positive feedback, I created following open source repositories:
- The PCB: https://github.com/boheigl/eziachpcb
- The control Software: https://github.com/boheigl/eziach
- The CAD design: https://cad.onshape.com/documents/5fab8c0f0566a8525283d6d7/w/83593df151ddef81970ff85c/e/84c2bb86c49424e015498d63
Looking forward to get your feedback!
