Already done: Internal clock with manual control. - Clock rate goes down when resistance goes up, opposite to expectation. Schematic fixes: - C1 is too small; need more than 100k to get below 200bpm - C1 is too small for a single 0.25 mm² wires, basic insulation, conductor diameter 2.4mm, outer diameter 2.3mm, size source Multi-Contact FLEXI-xV 1.5 (https://ec.staubli.com/AcroFiles/Catalogues/TM_Cab-Main-11014119_(en)_hi.pdf), bend radius 3 times outer diameter, generated with kicad-footprint-generator Soldered wire connection with double feed through strain relief, for a single 1 mm² wires, reinforced insulation, conductor diameter 0.65mm, outer diameter 3.5mm, size 39.5x8.3mm^2, drill diamater 1.15mm, pad diameter 2.4mm, outer diameter 2.3mm, see http://www.metz-connect.com/de/system/files/productfiles/Datenblatt_310591_RT063xxHBWC_OFF-022684T.pdf, script-generated using https://github.com/pointhi/kicad-footprint-generator/scripts/TerminalBlock_WAGO THT Terminal Block WAGO 236-403, 45Degree (cable under 45degree), 4 pins, pitch 5.08mm, size 40.6x10.6mm^2, drill diamater 0.7mm, pad diameter 2mm, size source Multi-Contact FLEXI-xV 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 Mounting Hardware, inside through hole 3.3mm, height 4, Wuerth electronics 9774065951 (https://katalog.we-online.de/em/datasheet/9774065951.pdf), generated with kicad-footprint-generator Samtec HLE .100" Tiger Beam Cost-effective Single Beam Socket Strip, HLE-133-02-xxx-DV-BE, 33 Pins per row (https://www.hirose.com/product/en/products/DF13/DF13-4P-1.25DS%2820%29/), generated with kicad-footprint-generator Stocko RFK MKS 16xx series connector, B30B-PUDSS (http://www.jst-mfg.com/product/pdf/eng/ePUD.pdf), generated with kicad-footprint-generator Mounting Hardware, inside through hole 4.5mm, height 1, Wuerth electronics 9774100960 (https://katalog.we-online.de/em/datasheet/9774100960.pdf,), generated with kicad-footprint-generator ipc_noLead_generator.py LFCSP, 32 Pin (http://ww1.microchip.com/downloads/en/DeviceDoc/8008S.pdf#page=20), generated with kicad-footprint-generator Samtec HLE .100" Tiger Beam Cost-effective Single Beam Socket Strip, HLE-124-02-xxx-DV-LC, 24 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 ipc_noLead_generator.py QFN, 16 Pin (https://toshiba.semicon-storage.com/info/docget.jsp?did=12858&prodName=TLP291-4), generated with kicad-footprint-generator ipc_noLead_generator.py QFN, 64 Pin (JEDEC MS-013AA, https://www.analog.com/media/en/package-pcb-resources/package/pkg_pdf/soic_wide-rw/rw_16.pdf), generated with kicad-footprint-generator Harting har-flexicon series connector, 502443-0470 (http://www.molex.com/pdm_docs/sd/5024430270_sd.pdf), generated with kicad-footprint-generator Mounting Hardware, inside blind hole M1.6, height 1.5, Wuerth electronics 9774025633 (https://katalog.we-online.com/em/datasheet/9774025633.pdf), generated with kicad-footprint-generator Molex LY 20 series connector, S4B-XH-A (http://www.jst-mfg.com/product/pdf/eng/eXH.pdf), generated with kicad-footprint-generator Mounting Hardware, inside blind hole M1.6, height 2.5, Wuerth electronics 9775096960 (https://katalog.we-online.com/em/datasheet/9775096960.pdf), generated with kicad-footprint-generator connector JST GH series connector, 202396-1207 (http://www.molex.com/pdm_docs/sd/2023960207_sd.pdf), generated with kicad-footprint-generator Samtec HLE .100" Tiger Beam Cost-effective Single Beam Socket.
