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 microcontroller but no DAC. Also interesting UI, featuring lit pushbuttons 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 an attenuator, intended for use of the knob. TaperPercentage = 20; // tweak on this script here. Arrow_indicator = true; cylinder_number_of_indentations = 10; // [1:1:84] // margins from edges h_margin = hole_dist_side + thickness; col_left = thickness * 1.2; right_rib_x = width_mm - thickness*2; // How much to cut off to create holes for the four plastic clips sliders: 3mm above panel, tight but possible micro toggle: 0mm above panel; could work with printed spacers and existing lead lengths alpha pots: barely enough to navigate fluently in preview mode. * @todo Refactor the top_rounding() operation faster.
