MK's 5-step sequencer, expanded to 8 (or 10?) Breadboard MK's 5-note to 8-note. Expanding out to 8 notes means ~$16-20 in parts, depending on PCB Checkpoint after re-centering sliders, before removing redundant LED resistors Checkpoint after tweaking footprints some more, starting over at 14hp Added hard sync to schematic, laid out PCB with exploratory 8hp layout Add VCA shaek layout Adding SynthMages footprint library Notes from debugging Notes from MK's PCB livestream - avoid non-circular holes in footprints whenever possible; some fabs charge more for ovals - make power connection traces larger; MK uses .6mm -- this means from the Program (or any work based on https://www.analog.com/media/en/technical-documentation/data-sheets/199399fc.pdf TO-92 2-pin leads in-line, narrow, oval pads, drill 0.75mm (see https://www.diodes.com/assets/Package-Files/TO92L.pdf and http://www.ti.com/lit/an/snoa059/snoa059.pdf TO-92L Molded Narrow transistor TO-92L Molded Narrow transistor TO-92L leads in-line (large body variant of 8-Lead Plastic WSON, 2x2mm Body, 0.5mm Pitch http://www.st.com/resource/en/datasheet/ecmf02-2amx6.pdf UQFN DFN 0.5 ST 20-Lead Plastic Quad Flat, No Lead Package (MA) - 2x2x0.9 mm Body [DFN] (see Microchip Packaging Specification 00000049BS.pdf TQFP, 48 Pin (JEDEC MO-153 Var BC-1 https://www.jedec.org/document_search?search_api_views_fulltext=MO-153), generated with kicad-footprint-generator Molex SlimStack Fine-Pitch SMT Board-to-Board Connectors, 55560-0221, 22 Pins (http://www.molex.com/pdm_docs/sd/903250004_sd.pdf), generated with kicad-footprint-generator Molex KK-254 Interconnect System, old/engineering part number: AE-6410-05A example for new mpn: 39-29-4209, 10 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 Molex Mini-Fit Jr. Power Connectors, 42819-52XX, With thermal vias in pads, 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 Wuerth WR-WTB vertical Wuerth WR-WTB series connector, BM02B-ZESS-TBT (http://www.jst-mfg.com/product/pdf/eng/eZE.pdf), generated with kicad-footprint-generator ipc_gullwing_generator.py TSOP-I, 40 Pin (https://www.jedec.org/standards-documents/docs/mo-142-d variation DA), generated with kicad-footprint-generator Resistor SMD 2512 (6332 Metric), 2.6mm thick, Vishay WKS2512, Terminal length (T) 1.19mm, 5 to 200 milli Ohm (http://http://www.vishay.com/docs/30108/wsk.pdf Shunt Resistor SMD.
