MK_VCO/Schematics/MK_VCO_RADIO_SHAEK.diy 5515 lines 2bd01a1ff2 Add schematic, start on PCB sandwich, making some final-ish decisions about connecting to front panel 82024e96c9 updated C14 footprint, traces, groundplane updated C14 footprint, traces, groundplane 2cbdb94ba9 updated C5 footprint & tracing; schematic annotation Add 55k-ish resistor to coarse knob (doublecheck this placement). Actual value unclear (see below).

Argument for a little bit of margin // margins from edges h_margin = hole_dist_side + thickness; output_column = width_mm - h_margin; col_left = h_margin; col_middle = col_left + (15.6 + 1.5 + 7 + 8); // pot + led + switch?
