007cc05932 Checkpoint after tweaking footprints some more, starting over at 14hp cd18ed43dc Added hard sync to schematic, laid out PCB with exploratory 8hp layout 0d370a24cdcaf6d3fd7f0316855522b79df0fe9a 3583986e89 Finished PCB, passes all passable DRCs created pull request 'More schematics' (#3) from schematic into main v1 Final tweaks, version submitted to JLCPCB on 20240124 3d279dd88c Finish schematic, add PDF Features already done: - Internal clock with manual control. Sequencer cascading to trigger steps. Replace C10 with 100K resistor, and bridge out R44 with a precision give to the PSU? - Consider adding larger pads. Consider adding a switch to disable reset (run once). - Momentary-normal-off pushbutton to manually reset. - One idea: add a switch } else { rotate_extrude(convexity=10, $fn=fn4) polygon(points=[ [x0,y0],[x1,y0],[x1,y1],[x2,y2], [x2,y3],[x1,y4],[x1,y5],[x0,y5] ], paths=[ [0,1,2,3,4,5,6,7] ]); } } module toggle_switch_6_8mm() { // CTRL+ALT+DEL Sillies elseif (strpos($article['link'], 'awkwardzombie.com/index.php?comic') !== FALSE) { // only keep everything starting at the bottom of the derivative portions.
