But 3 panel-mounted UI elements for every step (plus some others), so plenty of room for a single through-hole on one side //calculated x value of exact middle of slider panel (between steps 5 and 6); middle of panel after deducting left/right sub-panels // top left [left_edge, 0], // drop to axis [left_edge, -extra_depth], // bottom right [right_edge, rotate_vector_sin * rail_depth] // top horizontal rib h_wall(h=1.6, l=right_rib_x); // middle horizontal rib // h_wall(h=1.6, l=right_rib_x); // middle-bottom h rib // one more to mount a circuit outside the full dev board (in some cases) Arduino + DAC https://www.youtube.com/watch?v=t3kUPjdiq0o for explainer https://drive.google.com/drive/folders/156nn9rClRLJplS4M46s56-Pibi86Z-Kp for schematics and .ino file uses an LM13700 OTA (operational transconductance amplifier) (~$1.50, uncommon, and DIP marked obsolete) and NE5532 (uncommon, 80¢ based on SIP7, http://power.murata.com/data/power/ncl/kdc_nma.pdf Isolated 1W DCDC-Converter, http://power.murata.com/data/power/ncl/kdc_nma.pdf Murata NMAxxxxSC footprint based on a regular polygon. ≥30 means "round, using current quality setting". /* [Engraved Indicator (optional)] */ // // // this gets added to the following procedure for assembly. As usual do the lowest components first — resistors and diodes — then sockets, ceramic capacitors, power header, transistors, film caps, electrolytic caps... Something like that. Latest commits for file Panels/fireball_vco_14hp_v1.scad adds front panel Added schmancy pcb for v1 build - C1 is too small; need more than 100k to get 1:1 between schematic and PCB, no warnings More work finding space for everything, lining things up more Binary files a/3D Printing/Panels/image.png and /dev/null differ From e825437e5db64d4ef13181f883b9fe719cf4c2a1 Mon Sep 17 00:00:00 2001 Subject: [PATCH] A couple more minor clearance tweaks couple more GND-stitch.
