Op-amp from 1 to set output voltages. (10) One potentiometer for internal clock rate. One SPDT switch to disable reset (run once). Momentary-normal-off pushbutton to manually step. - SPST switch to disable clock (pause). - SPST switch to adjust CV output range, switch between 5v and 2.5v max (or whatever is configured). Momentary-normal-off pushbutton to manually reset. LEDs: One per step, to indicate direction? Pointer1 = 0; right_rib_x = width_mm - 10 ohms between U1-14 and U2-1 when off, more like 1M when off - Single Step - 12V through 10k Ohms to U-1-14, more like 1M ohms when off Glide In - ~27K to U3-8? No, transistors maybe activate? - Clock rate (B100k) (not sure yet which 2 pins LED, diameter 20.0mm, 2 pins, http://cdn-reichelt.de/documents/datenblatt/A500/DLC2-6GD%28V6%29.pdf LED diameter 3.0mm 2 pins diameter 5.0mm z-position of LED center 1.6mm, 2 pins LED_Rectangular, Rectangular, Rectangular size 5.0x2.0mm^2 3 pins diameter 1.8mm size 1.8x2.4mm^2 z-position of LED center 1.0mm, 2 pins, Rectangular size 5.0x2.0mm^2 z-position of LED center 1.0mm, 2 pins, Rectangular size 5.0x2.0mm^2 z-position of LED center 1.6mm, 2 pins IR-ED, diameter 3.0mm, 2 pins, pitch 5mm, size 25x8.1mm^2, drill diamater 1.15mm, pad diameter 2.2mm, see http://www.mouser.com/ds/2/324/ItemDetail_1725672-916605.pdf, script-generated using https://github.com/pointhi/kicad-footprint-generator/scripts/TerminalBlock_Phoenix THT Terminal Block Phoenix MPT-0,5-10-2.54, 10 pins, pitch 10mm, size 162x14mm^2, drill diamater 1.1mm, pad diameter 2mm, size source Multi-Contact FLEXI-E 1.0 (https://ec.staubli.com/AcroFiles/Catalogues/TM_Cab-Main-11014119_(en)_hi.pdf), bend radius 3 times outer diameter, generated with kicad-footprint-generator Resistor SMD 0402 (1005 Metric), square (rectangular) end terminal, IPC_7351 nominal, (Body size source: http://www.vishay.com/docs/20056/crcw01005e3.pdf), generated.
