Recently the Drone & Drama was noticed by others online:
Colin Drake made a version for Norns and shared it on lines.
A release of his work is scheduled for Toneburst.
DIY synths also added a link.
I hope to get another version made, but until then, thanks for the interest.
My collection of project files and guides to build more DIY electronic musical instruments that I designed over my research/practice are now available on GITHUB and HACKADAY.
Nano Perc v1 (percussive sounds from an arduino nano)
D&D Teensy (pocket sized Drone & Drama from a Teensy 3.2 / 4.0)
Squeal & Scrape (9v amp & contact microphone for workshops)
