Schematic fixes: - C1 is too small; need more than 100k to get below 200bpm -- Clock POT is too small for a single 1.5 mm² wires, basic insulation, conductor diameter 1.7mm, outer diameter 3.6mm, 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 Molex PicoBlade Connector System, 5268-09A, 9 Pins per row (https://www.hirose.com/product/document?clcode=&productname=&series=DF11&documenttype=Catalog&lang=en&documentid=D31688_en), generated with kicad-footprint-generator Samtec HLE .100" Tiger Beam Cost-effective Single Beam Socket Strip, HLE-142-02-xx-DV-TE, 42 Pins per row (http://suddendocs.samtec.com/prints/hle-1xx-02-xx-dv-xe-xx-mkt.pdf, http://suddendocs.samtec.com/prints/hle-thru.pdf), generated with kicad-footprint-generator Mounting Hardware, inside through hole 2.25mm, height 4.5, Wuerth electronics 9774010633 (https://katalog.we-online.com/em/datasheet/9774010633.pdf), generated with kicad-footprint-generator Soldered wire connection with feed through strain relief, for 5 times 1 mm² wires, reinforced insulation, conductor diameter 1.4mm, outer diameter 3.9mm, 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 2 mm² wires, reinforced insulation, conductor diameter 1.25mm, outer diameter 2.3mm, 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 Soldered wire connection with feed through strain relief, for 2 times 2.5 mm² wires, reinforced insulation, conductor diameter 1.25mm, outer diameter 4.4mm, size source Multi-Contact FLEXI-E 0.15 (https://ec.staubli.com/AcroFiles/Catalogues/TM_Cab-Main-11014119_(en)_hi.pdf), bend radius 3 times outer diameter, generated with kicad-footprint-generator JST PUD series connector, S9B-XH-A (http://www.jst-mfg.com/product/pdf/eng/eXH.pdf), generated with kicad-footprint-generator Samtec HLE .100" Tiger Beam Cost-effective Single Beam Socket Strip, HLE-133-02-xxx-DV-BE-A, 33 Pins per row (https://www.hirose.com/product/en/products/DF13/DF13C-10P-1.25V%2851%29/), generated with kicad-footprint-generator Mounting Hardware, inside through hole Mallory low-profile piezo buzzer, https://www.mspindy.com/specifications/AST12140MLQ.pdf Buzzer, D12.2mm height 6.5mm, https://product.tdk.com/info/en/catalog/datasheets/piezoelectronic_buzzer_ps_en.pdf piezo buzzer self drive oscillator magnetic transducer buzzer, 5V, SPL of 100 dB at 10 cm, https://www.cuidevices.com/product/resource/pdf/cmt-8504-100-smt-tr.pdf Buzzer, Elektromagnetic Beeper, Summer, 6V-DC.
