With other material in a ring arrangement; a challenging PCB and/or print job! See PDF at https://raw.githubusercontent.com/kassu/kassutronics/master/documentation/Quantizer/Quantizer_Build_Docs_1.1A.pdf for explanation about PWM smoothing; essentially a 4-stage RC network but with buffering between (some) stages. Needs a _big_ knob, these are for steps only row_5 = row_4 + vertical_space/7; row_6 = row_5 + vertical_space/7; cv_in_1a = [left_col, row_3, 0]; pwm_duty = [width_mm - h_margin - working_width/8, row_2, 0]; } // label the whole must be included in height. The shaft length is also not counted. KnobHeight = 20; // tweak on this and/or Hagiwo's quantizer, if going digital ** https://note.com/solder_state/n/nde97a0516f03 and https://www.youtube.com/watch?v=op_DhPr2goc ** arduino nano clone (atmega 328p), 12-bit dac.
