CV Generators Ornament & Crime a highly recommenced "polymorphic CV generator" Wave Folder using LM13700: https://kassu2000.blogspot.com/2021/11/wavefolder.html atari punk console could go here LMNC built an ancient NOS one? Midi? Or analog gate signals directly? Generate an envelope from an audio source instead of the main (cylindrical or conical) knob shape, without the two clockwise-most pins, looking from below. Clock rate goes down when resistance goes up, opposite to expectation. Glide fix glide fix Notes from MK's PCB livestream Footprints: - avoid non-circular holes in footprints whenever possible; some fabs charge more for ovals vias connect through the power safety block and into any non-high-impedence connections; that is, fat traces to chip power, but not to front panel and Pin 1, steel retention lug, horizontal PCB mount, retention spring, https://www.neutrik.com/en/product/ncj6fi-v Combo I series, 3 pole male XLR receptacle, grounding: mating connector shell to pin1 and front panel, vertical PCB mount, https://www.neutrik.com/en/product/nc3mahr A Series, 3 pole XLR female receptacle with 6.35mm (1/4in) mono jack, switched, with chrome ferrule and offset PCB pins, https://www.neutrik.com/en/product/nmj4hhd2 M Series, 6.35mm (1/4in) stereo jack, switched, half threaded nose, sleeve contact/front panel connection, https://www.neutrik.com/en/product/nrj4hh-1 Slim Jacks, 6.35mm (1/4in) stereo jack, switched, half threaded nose, https://www.neutrik.com/en/product/nrj6hf-au Slim Jacks, 6.35mm (1/4in) mono jack without switching contact, vertical PCB mount, http://cherryamericas.com/wp-content/uploads/2014/12/mx_cat.pdf Cherry MX keyswitch 1.75u plate Cherry MX keyswitch, 6.25u, PCB mount, https://www.neutrik.com/en/product/nc5fah A Series, 5 pole female XLR receptacle, grounding: separate ground contact to mating connector shell and front panel, horizontal PCB mount, retention spring, https://www.neutrik.com/en/product/ncj10fi-v AA Series, 3 pole male XLR receptacle, grounding: mating connector shell and front panel, vertical PCB mount, asymmetric push, https://www.neutrik.com/en/product/nc3fbh2-da B Series, 3 pole female XLR receptacle, grounding.
