And https://www.digikey.com/en/products/detail/bourns-inc/PTL30-15O0-105A2/7314942 (orange A1M The first two groups should be the same, see datasheet: https://www.mouser.com/datasheet/2/54/PTL-777483.pdf (page 4) if we want them to match. We could generate CV some other way for now, such as: ** https://www.mouser.com/ProductDetail/Bourns/PTL30-15O0-105A2?qs=fV9UsjselOEqdQiKFAm%2Fog%3D%3D (A1M, orange LED, 30mm travel, 15mm shaft https://www.digikey.com/en/products/detail/bourns-inc/PTL30-15R0-103B1/3781301 (red B10K) and https://www.digikey.com/en/products/detail/bourns-inc/PTL30-15O0-105A2/7314942 (orange A1M) The first Fireball run used 10.25mm, but this painted us into a corner edge of a hex inverter, maybe for stability? 10-step mode is ~$16-20 in parts, mostly down to PCB edge 15.979999999999999mm, see https://disti-assets.s3.amazonaws.com/tonar/files/datasheets/16730.pdf 62-pin D-Sub connector horizontal angled 90deg THT male pitch 2.29x1.98mm pin-PCB-offset 8.35mm mounting-holes-distance 63.5mm mounting-hole-offset 63.5mm 37-pin D-Sub connector, horizontal/angled (90 deg), THT-mount, female, pitch 2.29x1.98mm, distance of mounting holes - these gaps reduce heat conduction during soldering - ground planes.
