My Open Source / Public Eurorack projects

Two isolated 12V wall bricks in, +12V / -12V / +5V out on one keyed Mini-Fit Jr connector plus one standard Eurorack 16-pin bus header. Built as a 4HP 3U Eurorack module: 19.80 x 110.0 mm PCB behind a 20.00 mm panel, assembled on BOTH faces. The PCB requires 2oz outer copper — see BOM.csv. The big discretes (Schottkys, PTC discs, bulk electrolytics) are VERTICAL through-hole on the back face — a standing part packs as a dot where its SMD form is a slab, the density lesson taken from the Synthrotek Power UP. Small parts are SMD; the front face carries the panel furniture and little else, which…
