BackGenerator synth module. Layout and panel are Kosmo format. * [Schematic](Docs/precadsr.pdf) * PCB layout: [front](Docs/precadsr_layout_front.pdf), [back](Docs/precadsr_layout_back.pdf) * [BOM](Docs/precadsr_bom.md) * [Build notes](Docs/build.md ## GitHub repository * [https://github.com/holmesrichards/precadsr](https://github.com/holmesrichards/precadsr ## Submodules This repo uses submodules aoKicad and Kosmo\_panel. To clone: submodules avoid non-circular holes in footprints whenever possible; some fabs charge more for ovals - make power connection traces larger; MK uses a ground plane. - when pressed, short +12V and Reset In socket - Reset Socket to U3-3 = capacitor measurement roughly 15nF (has a resistor as well Once/Cont When in Cont mode shorts Casc Out - 1K to TP5 - Gate out, with probably +12v gates. Variable step count, 1-10 steps possible (with 2-3 extra switch positions to re-use for frequently-swapped positions). External reset via socket. External reset via socket. - External reset via socket. External reset via momentary push button. - Play continuously or play once (switch to select segments from each step. Could add a voltage to trigger a second sequencer's run, which then re-triggers the first. More feature ideas: Trigger out - CLK out - RESET / CASCADE out - CV Range - Once/Cont When in Cont mode shorts Casc Out normal to TP10, optional 2x Toggle Switches, 3pin: - CV out, with probably +12v gates.
- Diameter=12.5mm, height=25mm, Non-Polar Electrolytic Capacitor C.
