KitsBlips

Monorepo for my Eurorack/synthesizer hobby projects! (that's me, I'm kit)

Everything is always in a state of "not-quite-finished". if something is unclear or unusable in its current state, and you want to use it, feel free to open an issue or contact me.

For technical reasons, this project is ordered by toolset and not by module. this means the full source for a single module may be across multiple folders! Sorry.

unless otherwise listed, all code is MIT licensed. All hardware designs and graphics (kicad, svg etc) are CC-BY-SA 4.0.

Building/Installing

Each project/folder has a specific readme that includes extra steps if necessary, but in general, builds are managed using cmake.

text
$ mkdir -p <folder>/build && cd <folder>/build
$ cmake .. -DCMAKE_BUILD_TYPE=<build type: Debug, MinSizeRel, RelWithDebInfo>
$ cmake --build . --config=<the build type>
$ cmake --install . --prefix <location> # if the target supports installation
$ ctest # if the target has unit tests

once you have all your configurations set up, you can quickly rebuild all/run tests using rebuild-all.sh.

AI statement

KitsBlips will not accept PRs that are generated wholly or in significant part by generative AI. Future development will not use Generative AI.

There are a few older commits where I tried it for automatic refactoring, found it less than successful, and cleaned it up afterward. You can try the same thing; I wouldn't be able to tell the difference probably, but my conclusion to that experiment was that it wasn't worth it at the time.

Questions

How big is the Stylophone-1968 PCB?

It measures 150 × 100 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Stylophone-1968 use?

91 parts, built around the BC337. 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 Stylophone-1968 KiCad files?

From the Alloyed/KitsBlips repository on GitHub, at the commit this page was made from: the board is kicad/stylophone/stylophone-1968.kicad_pcb and its schematic kicad/4knobs/4knobs.circuitjs.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Stylophone-1968 design in my own project?

Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
