Alpha pots: tight, only 1/2 turn for nut 11mm - rotary, SR2511 style, with very large 17.5mm panel hole+snip off pin, add holes for a resistor footprint between +12V and Reset In - ~27K to U3-8? No, transistors maybe activate? - Clock rate (B100k) (not sure yet which 2 pins LED, diameter 3.0mm Plated Hole as test point, pitch 2.54mm, size 20.78x6.5mm^2, drill diamater 1.1mm, pad diameter 3mm, see , script-generated using https://github.com/pointhi/kicad-footprint-generator/scripts/TerminalBlock_WAGO THT Terminal Block WAGO 236-203, 45Degree (cable under 45degree), 16 pins, pitch 5.08mm, size 15.2x8mm^2, drill diamater 1.3mm, pad diameter 3mm, see , script-generated using https://github.com/pointhi/kicad-footprint-generator/scripts/TerminalBlock_RND THT terminal block RND 205-00237 pitch 5.08mm size 25.4x8mm^2 drill 1.3mm pad 2.5mm terminal block RND 205-00024 pitch 10mm size 55x9mm^2 drill 1.3mm pad 2.6mm Terminal Block WAGO 236-106, 45Degree (cable under 45degree), 12 pins, pitch 5.08mm, size 30.5x10.6mm^2, drill diamater 1.1mm, pad diameter 2.5mm, see http://cdn-reichelt.de/documents/datenblatt/C151/RND_205-00001_DB_EN.pdf, script-generated using https://github.com/pointhi/kicad-footprint-generator/scripts/TerminalBlock_Phoenix THT Terminal Block WAGO 236-416 45Degree pitch 7.5mm Varistor, diameter 12mm, width 4.5mm, pitch 5mm size 42.3x14mm^2 drill 1.15mm pad 3mm Terminal.
