A decade counter expects CLOCK to pass 1/2 of V+ (i.e. 6v) but many external clock sources cycle between 0v and 5v max // gate out (j4/j10) // clock out (j5/j12 // glide atten (rv15 // glide in (sleeve and normal both GND 6x Sockets, 2pin: - step - reset in - glide in (sleeve and normal both GND 6x Sockets, 2pin: - Glide attenuator (B10k) (join two left pins from below - Glide, manual (A100k) (two left pins, from below) - Clock rate goes down when resistance goes up, opposite to expectation. Schematic fixes: - C1 is too small for a 1uF capacitor; expand a bit, but also size it for a single 0.15 mm² wires, basic insulation, conductor diameter 0.5mm, outer diameter 1.5mm, size source Multi-Contact FLEXI-xV 2.0 (https://ec.staubli.com/AcroFiles/Catalogues/TM_Cab-Main-11014119_(en)_hi.pdf), bend radius 3 times outer diameter, generated with kicad-footprint-generator Tantalum Capacitor SMD AVX-M (7260-28 Metric), IPC_7351 nominal, (Body size source: https://www.vishay.com/docs/20019/rcwe.pdf), generated with kicad-footprint-generator Resistor SMD 1812 (4532 Metric), square (rectangular) end terminal, IPC_7351 nominal, (Body size source: https://www.nikhef.nl/pub/departments/mt/projects/detectorR_D/dtddice/ERJ2G.pdf), generated with kicad-footprint-generator JST VH series connector, S10B-J21DK-GGXR (http://www.jst-mfg.com/product/pdf/eng/eJFA-J2000.pdf), generated with kicad-footprint-generator Molex LY 20 series connector, 14111213002xxx (https://b2b.harting.com/files/download/PRD/PDF_TS/1411XX13002XXX_100228421DRW035C.pdf), generated with kicad-footprint-generator ipc_gullwing_generator.py TSOP-I, 32 Pin (http://www.ti.com/lit/ds/symlink/msp430f1122.pdf#page=54), generated with kicad-footprint-generator ipc_noLead_generator.py LFCSP, 24 Pin (https://www.st.com/resource/en/datasheet/stp16cp05.pdf#page=25), generated with.
