If desired, copy the files from 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 avoid non-circular holes in footprints whenever possible; some fabs charge more for ovals avoid non-circular holes in footprints whenever possible; some fabs charge more for ovals - make power connection traces larger; MK uses a CA3080 OTA, an expensive and rare chip these days ($3/ea on amazon, maybe fakes) VCA MK's VCA Probably a straightforward build: one op-amp, four transistors and some supporting components. ~$6 in parts, depending mainly on whether 8+6 pins + hardware fits on shaek board or similar size perf.
