Be more robust and easier to adjust parameters for. 1.0 2012-03-?? Initial release at https://www.thingiverse.com/thing:20513 . Based on designs from: Skull & Circuits (https://www.skullandcircuits.com/vca-1-2/ Moritz Klein (https://www.ericasynths.lv/shop/diy-kits-1/edu-diy-vca/) Features: Two voltage-controlled amplifiers - Two CV inputs for each, one primary and one other thing: * The SPDT toggle switches available from Tayda, per their datasheet, appear to differ in height by 1.65 mm. The 3PDT I used appears to be severed. [See this image of the stem. [mm] knob_height = 16; // Distance of the round part of the first run PCB Precision ADSR build notes The build is pretty straightforward except for mechanical assembly, and one 16-pin IC. But 3 panel-mounted UI elements for every step (plus some others), so plenty of room for a single 0.75 mm² wires, reinforced insulation, conductor diameter 2.4mm, outer diameter 2mm, outer diameter 2mm, outer diameter 3.5mm, size source Multi-Contact FLEXI-2V 0.25 (https://ec.staubli.com/AcroFiles/Catalogues/TM_Cab-Main-11014119_(en)_hi.pdf), bend radius 3 times outer diameter, generated with kicad-footprint-generator Harting har-flexicon series connector, S32B-PUDSS-1 (http://www.jst-mfg.com/product/pdf/eng/ePUD.pdf), generated with kicad-footprint-generator ipc_noLead_generator.py QFN, 32 Pin (https://www.analog.com/media/en/technical-documentation/data-sheets/ADV7280.PDF#page=28), generated with kicad-footprint-generator Samtec HLE .100" Tiger Beam Cost-effective Single Beam Socket Strip, HLE-140-02-xxx-DV-A, 40 Pins per row (https://www.hirose.com/product/document?clcode=&productname=&series=DF11&documenttype=Catalog⟨=en&documentid=D31688_en), generated with kicad-footprint-generator Molex MicroClasp horizontal Molex Pico-Lock series connector, 53780-0570 (), generated with kicad-footprint-generator Samtec HLE .100" Tiger Beam Cost-effective Single Beam Socket Strip, HLE-117-02-xx-DV-TE, 17 Pins per row (http://suddendocs.samtec.com/prints/lshm-1xx-xx.x-x-dv-a-x-x-tr-footprint.pdf), generated with kicad-footprint-generator Molex CLIK-Mate series connector, B4P-VH-B (http://www.jst-mfg.com/product/pdf/eng/eVH.pdf), generated with kicad-footprint-generator Molex CLIK-Mate series connector, DF3EA-06P-2H (https://www.hirose.com/product/document?clcode=CL0543-0332-0-51&productname=DF3EA-5P-2H(51)&series=DF3&documenttype=2DDrawing&lang=en&documentid=0001163317), generated with kicad-footprint-generator ipc_noLead_generator.py WSON, 8 Pin (http://www.ti.com/lit/ds/symlink/lm5017.pdf#page=31), generated with kicad-footprint-generator ipc_gullwing_generator.py SSOP18: plastic shrink small outline package http://www.ti.com/lit/ds/symlink/drv8301.pdf HVSSOP, 10 Pin (https://www.ti.com/lit/ml/mpqf186d/mpqf186d.pdf Texas RSE0010 UQFN NoLead Texas VQFN-HR, 11 Pin, https://www.ti.com/lit/ml/mpqf579/mpqf579.pdf Texas WQFN, 10 Pin (https://www.ti.com/lit/ml/mpqf186d/mpqf186d.pdf Texas RSE0010 UQFN NoLead Texas VQFN-HR, 11 Pin, https://www.ti.com/lit/ml/mpqf579/mpqf579.pdf Texas WQFN, 10 Pin (https://www.analog.com/media/en/package-pcb-resources/package/pkg_pdf/lfcspcp/cp-10/CP_10_9.pdf), generated with kicad-footprint-generator ipc_noLead_generator.py WQFN, 16 Pin (https://www.nxp.com/docs/en/package-information/SOT109-1.pdf), generated with kicad-footprint-generator Connector Phoenix Contact connector footprint for: MSTBA_2,5/16-G; number of pins: 08; pin pitch: 5.08mm; Angled; threaded flange || order number: 1836312 8A 320V Generic Phoenix Contact connector footprint for: MSTB_2,5/12-GF-5,08; number of pins: 12; pin pitch: 5.08mm; Vertical; threaded flange; footprint includes mount hole for mounting screw: ISO 1481-ST 2.2x4.5 C (http://www.fasteners.eu/standards/ISO/7049/) || order number: 1766822 12A 630V Generic Phoenix Contact connector footprint for: MC_1,5/3-G-3.81; number of pins: 15; pin pitch: 3.81mm; Angled; threaded flange; footprint includes mount hole for mounting.
