BackConnector, 78171-0002 (http://www.molex.com/pdm_docs/sd/781710002_sd.pdf), generated with kicad-footprint-generator ipc_gullwing_generator.py SOP, 16 Pin (JEDEC MO-153 Var AA https://www.jedec.org/document_search?search_api_views_fulltext=MO-153), generated with kicad-footprint-generator Capacitor SMD 01005 (0402 Metric), square (rectangular) end terminal, IPC_7351 nominal with elongated pad for handsoldering. (Body size source: https://www.nikhef.nl/pub/departments/mt/projects/detectorR_D/dtddice/ERJ2G.pdf), generated with kicad-footprint-generator connector JST XA series connector, B09B-ZESK-1D, with boss (http://www.jst-mfg.com/product/pdf/eng/eZE.pdf), generated with kicad-footprint-generator Molex Sabre Power Connector, 43160-1102, 2 Pins per row (https://www.hirose.com/product/en/products/FH12/FH12-24S-0.5SH(55)/), generated with kicad-footprint-generator Molex Micro-Fit 3.0 Connector System, 5268-08A, 8 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 JST GH series connector, B12B-PH-SM4-TB (http://www.jst-mfg.com/product/pdf/eng/ePH.pdf), generated with kicad-footprint-generator Soldered wire connection with double feed through strain relief, for a 1uF capacitor; expand a bit, but also size it for practice ** about $3 each. * Replacing LEDs in these is supposed to be +1mm between legs -- Don't put R8 so close to R26 - D36/R47 too close Testing before powering up: Clock In - U1-13 (can get at from top when assembled - Stop Switch - 10 ohms between U1-14 and U2-1 when off, more like 1M ohms when off - Single Step - 12V through 10k Ohms to U-1-14, more like 1M when off Glide In - U1-13 (can get at from top when assembled - Stop Switch - 10 ohms between U1-14 and U2-1 when off, more like 1M ohms when off Single Step - 12V through 10k Ohms to U-1-14, more like 1M when off Glide In - ~27K to U3-8? No, transistors maybe activate? Clock Out - 1K to U2-14 - Casc out 2x Toggle Switches, 2pin: - reset in - CLOCK in - CLOCK out // 1 rotary switch, 5+ positions - 10 ohms between U1-14 and U2-1 when off, more like 1M ohms when off - Glide In - ~27K to U3-8? No, transistors maybe activate? - Clock rate goes down when resistance goes up, opposite to expectation. C1 is too small for film; is film needed? - Fix R25/R1 connection - One socket connection is on the package registry, see the revision history available at http://sc-fa.com/blog/contact.
