DIY ELECTRIC HANDPAN

So DIY Handpan v1 didn't work out so well... :-(

So what's a chap to do? Pivot to an all-electric version, obvs.!

Concept

GeoPanIn this version I'm going to fabricate the handpan 'chassis' from laser-cut MDF plates, install some piezo pick-ups, and use some electronics-and-code to turn percussive energy into sound.

I'm most interested in something that makes sound in a relatively stand-alone way (i.e. via on-board speakers), but will try to include some kind of MIDI output as well.

One nice advantage of an electric handpan is that the note scale will be configurable.

OnShape

As per usual, I'm doing my design work in OnShape. The design covers the chassis, plus several templates/jigs/guides to help put the chassis together.

I'm going to use 6mm-thick MDF for my chassis, and will route-out a 60mm-diameter recess on the back of each note plate to bring the piezo pick-ups closer to the surface.

To explain a bit about the router jig (1st photo): the bits you see help locate the jig within the outermost ring (actually the handpan chassis base plate, not shown). The middle ring is then set aside. The inner ring slides around inside the (taped-down) outermost ring, limiting the cut to a 60mm-diameter circle.
