Properly assign potentiometer pads (i.e. Make the walls; a little bit of margin // margins from edges h_margin = hole_dist_side + thickness; output_column = width_mm - right_rib_thickness; // projection: make a hole with radius: ", hole_r , " at ", width_mm - h_margin; input_column = h_margin; working_height = height - v_margin; working_increment = working_height / (8+tolerance/5); // generally-useful spacing amount for vertical columns of stuff col_left = h_margin; bottom_row = v_margin + 12; row_1 = bottom_row + v_margin + 12; row_1 = v_margin+12; // draw a "vertical" wall to mount a circuit outside the full dev board (in some cases) Arduino + DAC https://www.youtube.com/watch?v=t3kUPjdiq0o for explainer https://drive.google.com/drive/folders/156nn9rClRLJplS4M46s56-Pibi86Z-Kp for schematics and .ino file uses an LM13700 OTA (operational transconductance amplifier) (~$1.50, uncommon, and DIP marked obsolete) and NE5532 (uncommon, 80¢ based on the front panel Added schmancy pcb for v2 front panel b77534e3fc83cf3f21d8c938a2ebb93ca539acd3 updated README.md updated README.md updated C14.
