Back5cacbfea2e Add polygon calculation for wing plates Seven-segment display. Can be passed in as parameter to eurorackPanel threeUHeight = 133.35; // overall 3u height panelInnerHeight = 110; //rail clearance = ~11.675mm, top and bottom railHeight = (threeUHeight-panelOuterHeight)/2; mountSurfaceHeight = (panelOuterHeight-panelInnerHeight-railHeight*2)/2; panelInnerOffset = (panelOuterHeight-panelInnerHeight)/2; echo("railHeight: ", railHeight); offsetToMountHoleCenterX = hp - holeOffset; // 1 rotary switch, 5+ positions 6 sockets Potentiometers: One potentiometer per step, to indicate direction? Pointer2 = 1; // [0:Flat, 1:Recessed, 2:Dome] // Do you want a D-shaped shafthole cross-section. 0 to keep labels all the same form factor, with maybe a little bit of margin // margins from edges h_margin = hole_dist_side + thickness; width_mm = hp_mm(h); difference() { union() { difference(){ color([.1,.1,.1]) panel(width); // lower h-rib reinforcer ## Photos ### Photos ## Documentation: * [Schematic](Docs/precadsr.pdf) * PCB layout: 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.
