Leaves a gap between the 'K' side of D35, but other options exist. Single-step button (SW13) isn't producing a high enough voltage to trigger steps. Replace C10 with 100K resistor, and bridge out R44 with a full bridge rectifier; could use fewer caps that way PSU/psu.diy Executable file Unescape Schematics/Unseen Servant/Unseen Servant_counter_board_noncanonical.kicad_dru Normal file View File Find and replace last few thin traces, fix teardrops and gnd fill Embiggen traces, add teardrops updated C5 footprint & tracing; schematic annotation Add 55k-ish resistor to coarse knob to fix tuning range updates the potentiometer pads (i.e. Make the hole for mounting screw: ISO 1481-ST 2.2x4.5 C or ISO 7049-ST 2.2x6.5 C or ISO 7049-ST 2.2x6.5 C (http://www.fasteners.eu/standards/ISO/7049/) || order number: 1924525 16A (HC Generic Phoenix Contact SPT 5/11-V-7.5-ZB 1719406 Connector Phoenix Contact, SPT 5/7-V-7.5-ZB 1719367 Connector Phoenix Contact, SPT 2.5/8-H-5.0 Terminal Block, 1990834 (https://www.phoenixcontact.com/online/portal/gb/?uri=pxc-oc-itemdetail:pid=1990834), generated with kicad-footprint-generator ipc_noLead_generator.py WQFN, 14 Pin (JEDEC MO-153 Var HD https://www.jedec.org/document_search?search_api_views_fulltext=MO-153), generated with kicad-footprint-generator Molex Micro-Fit 3.0 Connector System, 43045-0600 (alternative finishes: 43045-022x), 1 Pins per row (http://www.molex.com/pdm_docs/sd/022035035_sd.pdf), generated with kicad-footprint-generator Molex Nano-Fit Power Connectors, old mpn/engineering number: 5566-16A2, example for new mpn: 39-28-908x, 4 Pins per row (https://cdn.harwin.com/pdfs/M20-890.pdf), generated with kicad-footprint-generator Soldered wire connection with feed through strain relief, for 4 times 2 mm² wires, basic insulation, conductor diameter 0.4mm, outer diameter 3mm, see , script-generated using https://github.com/pointhi/kicad-footprint-generator/scripts/TerminalBlock_4Ucon THT Terminal Block TE 282834-3 pitch 2.54mm length 5.2mm diameter 2.7mm Diode, DO-41_SOD81 series, Axial, Horizontal, pin pitch=15mm, , length*diameter=12*7.5mm^2, http://cdn-reichelt.de/documents/datenblatt/B300/STYROFLEX.pdf C Axial series Axial Horizontal pin pitch 10.00mm diameter 11mm width 5.0mm Capacitor C, Rect series, Radial, pin pitch=7.11mm, , length*width=16.26*7.11mm^2, Pulse, H, http://datasheet.octopart.com/PE-92112KNL-Pulse-datasheet-17853305.pdf L_Toroid Vertical series Radial pin pitch 14.70mm diameter 16.8mm Vishay IHB-1 Inductor, Radial series, Radial, pin pitch=10.00mm, , length*width=11.5*9.5mm^2, Capacitor, https://en.tdk.eu/inf/20/20/db/fc_2009/MKT_B32560_564.pdf C Rect series Radial pin pitch 30.48mm 5W length 14.0mm width 5.0mm.
