BackNotes about component heights, swapping rotary and toggle switches From 8976a63dc06fa25beedf8d2553931872c491047e Mon Sep 17 00:00:00 2001 Subject: [PATCH] Add scad for v3.2 Stuff all teh scad files in aac0a4a5b4 Notes from MK's PCB livestream Footprints: - 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, needing only one side //calculated x value of exact middle of slider panel (between steps 5 and 6); middle of slider panel (between steps 5 and 6); middle of panel after deducting left/right sub-panels slider_center = (width_mm - left_panel_width - right_panel_width)/2 + left_panel_width; panel(width); // Top left: clock in, speed pot_p160(); // Left side: meta-step controls // step rotary switch with two LEDs K switch dual double-pole single-throw OFF-ON D Single Pole Single Throw (SPST) switch, small symbol D Switch, three position, dual pole double throw, separate symbols
