BackCases) 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 arduino nano (other options probably fine), two 74HC595 shift registers (accidentally a pile in my collection) and the hazards therein programming MCs to be fixed elsewhere Add schematic, start on PCB 7f9b624c8e tweaks layout with input from sam b0f8ee4ade traces added but maybe won't keep traces added but maybe won't keep traces_before_hard_sync Fix for when invisiblebread has no bread From 6a9c45505ac6d396b29028a4373b6ff337eac9d1 Mon Sep 17 00:00:00 2001 Subject: [PATCH] Added hard sync to schematic, laid out PCB with exploratory 8hp layout Bring in diylc and openscad design ## Mechanical assembly Regarding the board mounted potentiometers, there are two overlapping footprints provided for each, allowing you to use 7.5mm holes, not 6mm - alpha pots - 9.8mm, +2mm - rotary - 11.5mm, +3.5mm -- biggest by far, maybe 12.6mm? SR2511 series are 11.43? Maybe more? Distance between pcb and front panel, vertical PCB mount, https://www.neutrik.com/en/product/ncj9fi-v-0 Combo I series, 3 pole female XLR receptacle, grounding: ground contact to mating connector shell and front panel, vertical PCB mount, retention spring instead of A4 c852e5d6ad8630143a633f6c4ffcb4d705a43337 Add note resulting from real TL0x4, fix pots being backwards, tighten up schematic, fit letter instead of A4.
