DIY Eurorack Builds

A directory of Eurorack modules you can build yourself, open-source and commercial kits alike. Browse by module type, maker, mounting, or difficulty; each module links out to its source, panels, and kits. Kits that ship with SMD pre-soldered count as through-hole, since that is all you solder.

This is a community effort. If you build, design, or just know of something missing, come and say so in the Discord, or send it through the form. Corrections are just as welcome as additions.

Particular thanks to bish im famous and Fihdi, whose corrections and repository digging shaped a lot of what is here.
