Here’s a Eurorack Benjolin PCB/Panel I made a few years ago. It’s 10HP and uses SMD (0805) components with a few tweaks to the kweiwen version like boosted main output. I made some pretty big mistakes with the PCB (4012 chip backwards eeek!), so I only ended up building 2 of these, which are happily making strange noises in my hacked together DIY system.
I also started a Euro layout/panel for Hordijk’s Zeitgeist delay thing (with optional LDR to control delay time with light, which could be fun), but I never finished it. I’m thinking of picking that back up.
