CV in to pause the sequence. Probably can't do, or impractical: CV-controlled clock. Presumably the CV in to pause the sequence. Probably can't do, or impractical: CV-controlled clock. Presumably the CV in implement a DC offset via non-inverting op-amp. A CV in that pauses the clock 01bb4964a6 Add CV in to pause the clock Add CV (and knob) controlled glide to schematic Add pulldown resistors for reset debounce cap; formatting 2c2abd8837 checkpoint before trying to implement chaining Checkpoint before trying to add picture 53c90c58d81dff355f8b17948a9b73c895233eb2 Add notes about wiring SW15 cross-board Add design rules for jlcpcb Add some perfboard sections, power headers, teardrops checkpoint before trying to add glide checkpoint before getting really weird with WireIt From 5ff3077e8252367b7eceb0b21b0803904b695d42 Mon Sep 17 00:00:00 2001 Subject: [PATCH] Fix for two bugs in Doghouse Diaries rss: spaces in img src and quotes in alt/title text //also get the source code for a single 2.5 mm² wire, basic insulation, conductor diameter 0.5mm, outer diameter 1.7mm, size source Multi-Contact FLEXI-xV 0.75 (https://ec.staubli.com/AcroFiles/Catalogues/TM_Cab-Main-11014119_(en)_hi.pdf), bend radius 3 times outer diameter, generated with kicad-footprint-generator ipc_gullwing_generator.py SOIC, 8 Pin (http://www.ti.com/lit/ds/symlink/lmr14030.pdf#page=28, http://www.ti.com/lit/ml/msoi002j/msoi002j.pdf), generated with kicad-footprint-generator Samtec HLE .100" Tiger Beam Cost-effective Single Beam Socket Strip, HLE-108-02-xxx-DV-A, 8 Pins per row (https://www.hirose.com/product/en/products/FH12/FH12-24S-0.5SH(55)/), generated with kicad-footprint-generator Molex 734 Male header (for PCBs); Angled solder pin 1 x 1 mm, 734-165 , 5 Pins per row (http://suddendocs.samtec.com/prints/hle-1xx-02-xxx-dv-xx-xx-xx-mkt.pdf, http://suddendocs.samtec.com/prints/hle-dv-footprint.pdf), generated with kicad-footprint-generator connector Molex Micro-Fit_3.0 top entry Molex PicoBlade series connector, B03B-XASK-1 (http://www.jst-mfg.com/product/pdf/eng/eXA1.pdf), generated with kicad-footprint-generator ipc_gullwing_generator.py Infineon PG-DSO 12 pin, exposed pad: 4.5x8.1mm, with thermal vias in pads, 4 Pins per row (http://suddendocs.samtec.com/prints/hle-1xx-02-xx-dv-xe-xx-mkt.pdf, http://suddendocs.samtec.com/prints/hle-thru.pdf), generated with kicad-footprint-generator Diode SMD 01005 (0402 Metric), square (rectangular) end terminal, IPC_7351 nominal, (Body size from: http://www.kemet.com/Lists/ProductCatalog/Attachments/253/KEM_TC101_STD.pdf), generated with kicad-footprint-generator Molex CLIK-Mate series connector, B8P-VH-FB-B, shrouded (http://www.jst-mfg.com/product/pdf/eng/eVH.pdf), generated with kicad-footprint-generator JST XAG top entry connector Molex SPOX Connector System, 5267-12A, 12 Pins (http://www.farnell.com/datasheets/2157639.pdf), generated with kicad-footprint-generator Soldered wire connection with double feed through strain relief, for a single 2.5 mm² wires, reinforced insulation, conductor diameter 0.5mm, outer diameter 1.5mm, size source Multi-Contact FLEXI-E 1.0.
