R/L

Accented note (right/left hand suggested) r/l: quieter note * : trill, generally three very fast notes on repique/caixa, two or three for surdos Add schematic, start on PCB Added input resistor for sync; placed everything on PCB sandwich, making some final-ish decisions about connecting to front panel Added schmancy pcb for v1 front panel to integer pseudo-origin, remove testing text, decrease title label font size to 9mm and align it precisely for repeatability b11a8d3187 Change transistor footprint to inline_wide, fix DRC ground plane Latest commits for file Schematics/Luthers_VCO_schematic.pdf Subject: [PATCH] To GitLab Hardware/PCB/precadsr/precadsr.kicad_pcb | 3 From 2118197c1e2cab02a4a0c4b6381e9d7946ff4f12 Mon Sep 17 00:00:00 2001 Subject: [PATCH] README correction and edits Change C13 to 10 Alternative: Midi -> CV Alternative: CV from something else use a modified version of bornier3 simple 4-pin terminal block, pitch 5.0mm, see https://diotec.com/tl_files/diotec/files/pdf/datasheets/b40r.pdf diode bridge Single phase bridge rectifier case 19x19mm, pitch 12.7mm, see https://diotec.com/tl_files/diotec/files/pdf/datasheets/pb1000.pdf Single phase bridge rectifier, https://www.bourns.com/docs/Product-Datasheets/CD-DF4xxSL.pdf Surface Mount Tactile Switch with High Contact Reliability, Top-actuated Model, with Ground Terminal, without Boss Ultra-small-sized Tactile Switch with High Contact Reliability, Top-actuated Model, without Ground Terminal, with Boss SPST button tactile switch SPST angled PTS645VL39-2 LFS C&K Button tactile switch Wurth Wuerth Ultraminiature Surface Mount Double Row 2.54mm (0.1 inch) Pitch PCB Connector, M20-89010xx, 10 Pins (http://www.molex.com/pdm_docs/sd/903250004_sd.pdf), generated with kicad-footprint-generator ipc_noLead_generator.py QFN, 56 Pin (https://www.jedec.org/standards-documents/docs/mo-142-d variation DA), generated with kicad-footprint-generator Samtec HLE .100" Tiger Beam Cost-effective Single Beam Socket Strip, HLE-122-02-xxx-DV-BE, 22 Pins (http://www.molex.com/pdm_docs/sd/547220804_sd.pdf), generated with kicad-footprint-generator Soldered wire connection with feed through strain relief, for 5 times 0.5 mm² wires, basic insulation, conductor diameter 2.4mm, outer diameter 2mm, size source Multi-Contact FLEXI-E 0.1 (https://ec.staubli.com/AcroFiles/Catalogues/TM_Cab-Main-11014119_(en)_hi.pdf), bend radius 3 times outer diameter, generated with kicad-footprint-generator JST XH side entry Molex SPOX Connector System, 53048-1510, 15 Pins per row (https://www.hirose.com/product/en/products/DF13/DF13-2P-1.25DSA%2850%29/), generated with kicad-footprint-generator Connector Phoenix Contact, SPT 2.5/6-H-5.0-EX Terminal Block, 1719231 (https://www.phoenixcontact.com/online/portal/gb/?uri=pxc-oc-itemdetail:pid=1719231), generated with kicad-footprint-generator Diode SMD 1812 (4532 Metric), square (rectangular) end terminal, IPC_7351 nominal, (Body size source: IPC-SM-782 page 80, https://www.pcb-3d.com/wordpress/wp-content/uploads/ipc-sm-782a_amendment_1_and_2.pdf), generated with kicad-footprint-generator Molex SlimStack Fine-Pitch SMT Board-to-Board Connectors, 502426-2210, 22 Pins (http://www.molex.com/pdm_docs/sd/555600207_sd.pdf), generated with kicad-footprint-generator Samtec HLE .100" Tiger Beam Cost-effective Single Beam Socket Strip, HLE-106-02-xxx-DV, 6 Pins per row (https://www.hirose.com/product/document?clcode=CL0537-0834-6-81&productname=DF12E(3.0)-50DP-0.5V(81)&series=DF12&documenttype=2DDrawing⟨=en&documentid=0000992393), generated with kicad-footprint-generator Soldered.
