Back3c7abf2196 Move LED resistors next to transistors to save on panel wires More traces and vias, and net links Add four more switches/buttons, move LED drivers onto PCB Add a front-panel PCB d40f7ca1ca Experimenting with more panel layout ideas Initial stab at a charge no more than 100k to get 1:1 between schematic and PCB, no warnings More work finding space for everything, lining things up more Make slider and LED footprints match current OpenSCAD model Checkpoint after fixes but before shrinking boards Checkpoint after converting most things to SMD Latest commits for file Panels/fireball_vco_14hp_v1.scad adds front panel and Pin 1, vertical PCB mount, retention spring, https://www.neutrik.com/en/product/ncj10fi-v AA Series, 3 pole female XLR receptacle, grounding: mating connector shell to pin1 and front panel. - Current design uses six IDC 2×8 connectors with 4 positions D 4 rotary switches are actually 2p6t, which means only six different step counts are available until the replacement arrives - Wiring SW15 (once/stop) and cascade out is easier done via skywiring; only one tl074 and support Kassutronic's KS-20 https://kassu2000.blogspot.com/2019/07/ks-20-filter.html ** uses an arduino nano clone (atmega 328p), 12-bit dac (mcp4726) and small amounts of supporting hardware Microcontroller and smoothed PWM https://kassu2000.blogspot.com/2019/10/quantizer.html using a setscrew).
