BackGenerates a sequence of 8 voltages controllable by individual knobs. MK's 5-step sequencer, expanded to 8 (or 10?) Breadboard MK's 5-note to 8-note. Expanding out to 8 notes means ~$16-20 in parts, needing only one tl074 and support Kassutronic's KS-20 https://kassu2000.blogspot.com/2019/07/ks-20-filter.html ** uses an LM13700 OTA (operational transconductance amplifier) (~$1.50, uncommon, and DIP marked obsolete) and NE5532 (uncommon, 80¢ based on https://www.analog.com/media/en/technical-documentation/data-sheets/8063fa.pdf Altera BGA-36 V36 VBGA BGA-48 - pitch 0.8 mm Highspeed card edge connector for PCB's with 60 contacts (not polarized Highspeed card edge connector for 1.6mm PCB's with 50 contacts (not polarized Connector PCBEdge molex EDGELOCK Generic Phoenix Contact connector footprint for: MCV_1,5/8-GF-3.81; number of pins: 11; pin pitch: 5.08mm; Angled; threaded flange || order number: 1830622 8A 160V Generic Phoenix Contact SPT 2.5/7-H-5.0 1991024 Connector Phoenix Contact, SPT 1.5/9-H-3.5 Terminal Block, 1991053 (https://www.phoenixcontact.com/online/portal/gb/?uri=pxc-oc-itemdetail:pid=1991053), generated with kicad-footprint-generator Soldered wire connection, for 4 times 1.5 mm² wires, basic insulation, conductor diameter 0.9mm, outer diameter 3mm, see , script-generated using https://github.com/pointhi/kicad-footprint-generator/scripts/TerminalBlock_WAGO THT Terminal Block WAGO 804-108 45Degree pitch 5mm Varistor, diameter 12mm, width 5.1mm, pitch 7.5mm Varistor, diameter 12mm, width 4.3mm, pitch 7.5mm size 89x15mm^2 drill 1.2mm pad 3mm Terminal Block WAGO 236-601, 45Degree (cable under 45degree), 2 pins, diameter 3.0mm, 2 pins, diameter 3.0mm z-position of LED center 9.0mm.
