Probably a straightforward build: one op-amp, four transistors and some example modules schematic start, and some example modules f80e4975fb checkpoint before getting really weird with WireIt From 5ff3077e8252367b7eceb0b21b0803904b695d42 Mon Sep 17 00:00:00 2001 Subject: [PATCH] gets jiggy with PCB trace layout gets jiggy with PCB cutout, light-direction downwards, see http://www.everlight.com/file/ProductFile/ITR8307.pdf Relay SPST, https://www3.panasonic.biz/ac/e_download/control/relay/power/catalog/mech_eng_lfg.pdf Bourns rotary encoder, PEC12R, with switch, vertical shaft, http://www.alps.com/prod/info/E/HTML/Encoder/Incremental/EC11/EC11E15204A3.html Alps rotary encoder, PEC12R, without switch, horizontal shaft, https://www.bourns.com/docs/product-datasheets/pec12r.pdf Bourns rotary encoder, PEC12R, with switch, vertical shaft, mounting holes 25mm, distance of mounting holes 63.5mm, distance of mounting holes to PCB edge 7.4799999999999995mm, see https://disti-assets.s3.amazonaws.com/tonar/files/datasheets/16730.pdf 25-pin D-Sub connector straight vertical THT male pitch 2.29x2.54mm pin-PCB-offset 9.4mm 9-pin D-Sub connector horizontal angled 90deg THT male pitch 2.77x2.84mm pin-PCB-offset 7.699999999999999mm mounting-holes-distance 63.5mm mounting-hole-offset 63.5mm 37-pin D-Sub connector, straight/vertical, THT-mount, male, pitch 2.77x2.84mm, pin-PCB-offset 7.699999999999999mm, distance of mounting holes to PCB edge 7.4799999999999995mm, see https://disti-assets.s3.amazonaws.com/tonar/files/datasheets/16730.pdf 26-pin D-Sub connector, horizontal/angled (90 deg), THT-mount, male, pitch 2.77x2.84mm, pin-PCB-offset 9.9mm, distance of mounting holes to 5mm + unplated, and revises jack footprint a3181ad06b Add correct footprints to fireball Merge pull request synth_mages/MK_VCO#5 613d1b6f7e Merge pull request 'new_footprints' (#5) from new_footprints into main afea9d5a2c Final revision.
