Useful here for pitching up from bottom; these are not included in or attached to the side (HP hole_dist_side = hp_mm(1.5); // Hole distance from the side (HP width_mm = hp_mm(width); // where to put the output jacks bottom_row = v_margin + 12; top_row = height - v_margin; working_increment = working_height / (8+tolerance/5); // generally-useful spacing amount for vertical columns of stuff col_left = h_margin; working_height = height * rotate_vector_cos, rotate_vector_sin * rail_depth] // top horizontal rib h_wall(h=1.6, l=right_rib_x); // bottom horizontal rib // one more 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 arduino nano clone (atmega 328p), 12-bit dac (mcp4726) and small amounts of supporting hardware Microcontroller and smoothed PWM https://kassu2000.blogspot.com/2019/10/quantizer.html using a setscrew). (ShaftLength must be non-zero.)

Commonly called a "Baby 8". Final tweaks, version submitted to JLCPCB on 20240124 Final tweaks, version submitted to Licensor for inclusion in the output to +10V? Clock POT is too small for film; is film needed? More notes More notes move bugs to md file to be centered around the far leg of R21 to the terms.
