Welcome here =)

Here you can find all the resources I use to build my modules. You will also find my modules, their Kicad files, their schematics as well as my sources of inspiration and pictures/videos of the prototypes and finished modules

You will also find

A big list of open-source/open-hardware builders

All modules in the list are not necessarily in eurorack format, but all have their schematics available if not more

And

A list (in progress) of modules by category

These are the module's files and descriptions available in the list above but classified by category

Don't hesitate to participate if you find other sources of music/video schematics

Thing you can do to help :

  • Class thing in alphabetical order for the Open-hardware-builders list
  • Add new entry
  • Take a look at the modules by category and continue to class them
  • Look for typos
  • Have a good day =)

Questions

How big is the Drum k PCB?

It measures 95 × 100 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Drum k use?

62 parts. 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 Drum k KiCad files?

From the Pl0p/Modular_Synth repository on GitHub, at the commit this page was made from: the board is OLD/Drum-K/Kicad/Drum-k.kicad_pcb and its schematic Drum-K_MKII/Kicad/Controls.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Drum k design in my own project?

Its repository states no licence, so its author keeps all rights: ask Pl0p before reusing the design.
