My fiancee and I plan to build a modular synthesizer, for fun. Here's a repository to hold all kinds of stuff to do with that. I imagine it'll hold the following
- Schematic designs
- PCB designs derived from those schematic design
- Some 3D modeling for related hardware
- Any microcontroller code

Questions
How big is the Distortion PCB?
It measures 50 × 132.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Distortion use?
60 parts, built around the TL072. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Distortion KiCad files?
From the michd/modular-synth repository on GitHub, at the commit this page was made from: the board is modules/distortion/kicad/distortion.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Distortion design in my own project?
Its repository states no licence, so its author keeps all rights: ask michd before reusing the design.
