Open hardware eurorack synth modules
Based on [[https://github.com/TomWhitwell/TuringMachine/][Turing Machine]] on github.
- Converted schematics to Kicad - Front panel isn't converted, since Eagle source for that isn't available. Only raw gerbers exist.

TuringBack: common questions
How big is the TuringBack PCB?
The TuringBack measures 107 × 49.5 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the TuringBack?
45 components, from 20 distinct parts. The full bill of materials is listed on this page.
Where can I download the TuringBack design files?
From the jypma/modsynth repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the TuringBack design in my own project?
The repository has no license, so all rights stay with jypma. Use it as a reference, and ask the author before reusing the design.
