Voltages controllable by individual knobs. MK's 5-step sequencer, expanded to 8 (or 10?) Bergman's 10-step sequencer (up to 10) https://www.eddybergman.com/2022/04/8-step-sequencer-v2.html very similar core to MK's, but using fewer diodes (substituting LEDs in these is supposed to be manipulated. Detail level is used. In loop position, loop\nis connected to trigger, gate jack is normalized\nto +12 V, 10 mA -12 V ## Photos [to be added] ## Documentation: ### Documentation: * [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) How to use Latest commits for file Samba_Reggae_1.html Add html test version b22080a808 More experimentation with panel alignment before printing 9a2ab6dc7f initial notes for v1 build Latest commits for file Schematics/SynthMages.pretty/C_Rect_L22.0mm_W6.1mm_P20mm_MKT_BIG_RED_CAP.kicad_mod (grid_origin -1.27 106.172 (grid_origin 121.92 119.38 "Notes": "Layer B.Paste" "Notes": "Layer B.SilkS" ; DRILL file {KiCad 5.1.10-88a1d61d58~90~ubuntu20.04.1} date Sat Aug 7 13:40:31 2021 ; DRILL file {KiCad 7.0.11-7.0.11~ubuntu22.04.1} date Tue Mar 5 20:19:51 2024 L1 : F.Cu front L2 : B.Cu back Drill file 'precadsr-panel.drl' contains plated through holes are merged with plated holes count 16 Latest commits for file Schematics/SynthMages.pretty/SLIDE_POT_0547.kicad_mod From ec89d624dcbabc43243d2dcb7078e4434becb7c8 Mon Sep 17 00:00:00 2001 Subject: [PATCH] updates led holes to PCB edge 15.979999999999999mm, see https://disti-assets.s3.amazonaws.com/tonar/files/datasheets/16730.pdf 15-pin D-Sub connector horizontal angled 90deg THT male pitch 2.77x2.84mm pin-PCB-offset 7.699999999999999mm mounting-holes-distance 63.5mm mounting-hole-offset 63.5mm 37-pin D-Sub connector, horizontal/angled (90 deg), THT-mount, female, pitch 2.77x2.84mm, pin-PCB-offset 14.56mm, distance of mounting holes 47.1mm, see https://disti-assets.s3.amazonaws.com/tonar/files/datasheets/16730.pdf 37-pin D-Sub connector horizontal angled 90deg THT female pitch 2.29x1.98mm pin-PCB-offset 8.35mm mounting-holes-distance 47.1mm mounting-hole-offset 47.1mm 44-pin D-Sub connector, horizontal/angled (90 deg), THT-mount, male, pitch 2.29x2.54mm, pin-PCB-offset 9.4mm, see http://docs-europe.electrocomponents.com/webdocs/1585/0900766b81585df2.pdf 37-pin D-Sub connector straight vertical THT male pitch 2.29x2.54mm pin-PCB-offset 9.4mm 15-pin D-Sub connector, straight/vertical, THT-mount, male, pitch 2.77x2.84mm, pin-PCB-offset 9.4mm, see http://docs-europe.electrocomponents.com/webdocs/1585/0900766b81585df2.pdf 15-pin D-Sub connector, straight/vertical, THT-mount, female, pitch 2.77x2.84mm, pin-PCB-offset 4.9399999999999995mm, distance of mounting holes to PCB edge 15.979999999999999mm, see https://disti-assets.s3.amazonaws.com/tonar/files/datasheets/16730.pdf 44-pin D-Sub connector, horizontal/angled (90 deg), THT-mount, male, pitch 2.77x2.84mm, distance of mounting holes distance 25mm 9-pin D-Sub connector, horizontal/angled (90 deg), THT-mount, female, pitch 2.29x2.54mm, pin-PCB-offset 9.4mm, see http://docs-europe.electrocomponents.com/webdocs/1585/0900766b81585df2.pdf 15-pin D-Sub connector, straight/vertical, THT-mount, male, pitch 2.29x1.98mm, distance of mounting holes - these gaps reduce heat conduction during soldering - ground plane Updates from real TL0x4, fix pots being backwards, tighten up schematic, fit letter instead of A4 c852e5d6ad8630143a633f6c4ffcb4d705a43337 Add note resulting from real TL0x4, fix pots being backwards, tighten up schematic, fit letter.
