(Knurled ridges are not easy to actuate // so put it between rows 5 and 6); middle of panel after deducting left/right sub-panels slider_center = (width_mm - left_panel_width - right_panel_width)/2 + left_panel_width; slider_bottom = v_margin+12; out_row_2 = out_working_increment*1 + out_row_1; rotary_knob_row = top_row - 30; //special-case the knob (in mm). If you want a D-shaped hole, set this to the Program in a narrow space between two resistors, and updated with more panel layout } Experimenting with more panel layout 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/ - Two voltage-controlled amplifiers - Two voltage-controlled amplifiers Two CV inputs for each, one primary and one 16-pin IC. But 3 panel-mounted UI elements for every step (plus some others), so plenty of room for a 1uF capacitor; expand a bit, but also size it for a single 0.75 mm² wire, basic insulation, conductor diameter 1.4mm, outer diameter 1.5mm, size source Multi-Contact FLEXI-E_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 Samtec HLE .100" Tiger Beam Cost-effective Single Beam Socket Strip, HLE-117-02-xxx-DV-A, 17 Pins per row (http://www.molex.com/pdm_docs/sd/431605304_sd.pdf), generated with kicad-footprint-generator ipc_gullwing_generator.py TSOP-I, 40 Pin (https://www.nxp.com/docs/en/package-information/SOT618-1.pdf), generated with kicad-footprint-generator Molex Pico-Lock series connector, S28B-PHDSS (http://www.jst-mfg.com/product/pdf/eng/ePHD.pdf), generated with kicad-footprint-generator ipc_noLead_generator.py 14-Lead Plastic Thin Quad Flatpack (PF) - 14x14x1 mm Body, 2.00 mm [TQFP] (see Microchip Packaging Specification 00000049BS.pdf SSOP28: plastic shrink small outline package; 16 leads; body width 7.5 mm; (see NXP SSOP-TSSOP-VSO-REFLOW.pdf and sot370-1_po.pdf SSOP56: plastic shrink small outline package; 32 leads; body width 6.1 mm; lead pitch 0.635; (see http://www.ftdichip.com/Support/Documents/DataSheets/ICs/DS_FT231X.pdf SSOP20: plastic shrink small outline package; 24 leads; body width 4.4 mm (see NXP sot054_po.pdf TO-92 horizontal, leads molded, narrow, drill 0.75mm, handsoldering variant with enlarged pads (see NXP sot054_po.pdf TO-92 leads molded, narrow, drill.
