Connect a 100k resistor between coarse and +12V, value unknown Align panel to PSU PCB (will affect choice of sitching hardware). Consider aesthetics and prcticality of stand-offs from front panel. Possibly do as an external CV-to-pulse-rate module? Is this even useful? - Seven-segment display. Can be done, but requires a trigger-sized pulse on input. Portamento (aka slew rate controller aka glide). - Knob version fairly simple. CV version maybe possible, but a bitmap generator is available for arbitrary text (using size = 200) at: https://www.myfonts.com/collections/quentin-font-urw?tab=individualStyles font_for_label = "Futura Md BT:style=Medium"; font_for_title = "Futura Md BT:style=Medium"; STLs, 10hp version, others schematics width_mm=60; height=10; More experimentation with panel title fonts } STLs, 10hp version, others schematics More experimentation with panel title fonts 62cb30efbf Initial kicad, images, gitignore for kicad backups From.
