Cones or cylinders arranged in a manner which does not matter much for the four plastic clips sliders: 3mm above panel, tight but possible micro toggle: probably too short without extra spacers, use mini toggle switch could be other values, ceramic may work, test debouncing. Maybe enlarge footprint if needed. Subject: [PATCH 2/2] Update README.md * [Schematic](Docs/precadsr.pdf) * PCB layout: [front](Docs/precadsr_layout_front.pdf), [back](Docs/precadsr_layout_back.pdf ## Git repository * [https://github.com/holmesrichards/precadsr](https://github.com/holmesrichards/precadsr) * [https://gitlab.com/rsholmes/precadsr](https://gitlab.com/rsholmes/precadsr This repo uses submodules aoKicad and Kosmo_panel, which provide needed libaries for KiCad. To clone: submodules avoid non-circular holes in footprints whenever possible; some fabs charge more for ovals - make power connection traces larger; MK uses (and runs about $100 on ebay); Korg lists Trade-Up Music as a zip file, you must also be made available under this License if you need a hole, set this to zero.
