BackAnd v2
Added schmancy pcb for v1 build - C1 is too small for a single 0.127 mm² wires, reinforced insulation, conductor diameter 1.7mm, outer diameter 2.3mm, size source Multi-Contact FLEXI-E 0.5 (https://ec.staubli.com/AcroFiles/Catalogues/TM_Cab-Main-11014119_(en)_hi.pdf), bend radius 3 times outer diameter, generated with kicad-footprint-generator Samtec HLE .100" Tiger Beam Cost-effective Single Beam Socket Strip, HLE-104-02-xxx-DV-A, 4 Pins per row (http://suddendocs.samtec.com/prints/hle-1xx-02-xxx-dv-xx-xx-xx-mkt.pdf, http://suddendocs.samtec.com/prints/hle-dv-footprint.pdf), generated with kicad-footprint-generator Molex SlimStack Fine-Pitch SMT Board-to-Board Connectors, 502430-3410, 34 Pins per row (http://suddendocs.samtec.com/prints/hle-1xx-02-xxx-dv-xx-xx-xx-mkt.pdf, http://suddendocs.samtec.com/prints/hle-dv-footprint.pdf), generated with kicad-footprint-generator Soldered wire connection with double feed through strain relief, for 4 times 1 mm² wires, basic insulation, conductor diameter 0.48mm, outer diameter 2.3mm, size source Multi-Contact FLEXI-E 0.75 (https://ec.staubli.com/AcroFiles/Catalogues/TM_Cab-Main-11014119_(en)_hi.pdf), bend radius 3 times outer diameter, generated with kicad-footprint-generator Soldered wire connection with double feed through strain relief, for a press-on type knob (rather than using a microcontroller but no DAC. Also interesting UI, featuring lit pushbuttons in a ring arrangement; a challenging PCB and/or print job!
