BackFront - Clock rate (B100k) (not sure yet which 2 pins LED, diameter 3.0mm z-position of LED center 1.0mm 2 pins diameter 10.0mm 2 pins Datasheet can 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 also do all-different colors, but unfortunately Mouser only has A1Ms in orange. Expensive, about $3 each. * Replacing LEDs in sliders, lit for each Contribution on the other - ground plane Change transistor footprint to inline_wide, fix DRC ground plane Updates from real TL0x4s re-re-remove the mysterious extra trace 4c5e03f875a81278be4b8089dd10dd98b0c86e5d Add scad for v3.2 f33ea6a168329cd0061e01c376cbd377f46ddc60 @circuitlocution.com created pull request 'More schematics' (#3) from schematic by Eeschema 5.1.10-88a1d61d58~90~ubuntu20.04.1 **Component Count:** 76 Docs/precadsr_layout_back.pdf Normal file View File From 744b72ef7e0d94fccfae99ec3cb3514981ac4616 Mon Sep 17 00:00:00 2001 Subject: [PATCH 09/13] Notes from MK's PCB livestream Footprints: - avoid non-circular holes in footprints whenever possible; some fabs charge more for ovals avoid non-circular holes in footprints whenever possible; some fabs charge more for ovals - make power connection traces larger; MK uses a CA3080 OTA, an expensive and rare chip these days ($3/ea on amazon, maybe fakes) VCA MK's VCA Probably a straightforward build: one op-amp, four transistors and some example.
