There seems to be interest over in the Serge thread in folks building the small microcontroller c.v. and trigger unit I made this month:
- 4 control voltages out, 0 ~ +8V, ~2kHz max bandwidth
- 4 trigger outs, 0 ~ 8V
- Based on a Feather M0 board
- Optional display
- Programmable in C++ or Circuit Python
- I made it for Serge, but could easily be adapted for Eurorack.
Here’s it being a sine LFO:
I’m running a MIDI looper on it - so it can easily be a USB MIDI device, but with a little coding you can make it be anything you want.
I’m game to run a workshop pandemic style, that is, all on line: As group we’ll work through the schematic, parts, building, and coding together - tweaking or customizing the design as we go… I’ll supply the initial design, walk people through the build, (there are some construction tips that made the final thing nice), and help with coding.
I think this makes an absolutely great medium project to build, requiring only simple soldering, and some physical hacking for your enclosure. The coding is pretty easy, and I’ll supply working starting points.
Workshop site: https://github.com/mzero/1205thing/wiki
- review the schematic
- overview of construction
- bill of materials / order your parts
Clarification: My aim is to run the workshop right here - in this thread! I’m willing to hold some zoom meetings as needed - but I think we do it mostly right here, without being on-line at the same time.
