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 buffering between (some) stages. Needs a TLC7524/AD7524 (a simple DAC that's still sorta analog) and a switch to adjust parameters for. 1.0 2012-03-?? Initial release at https://www.thingiverse.com/thing:20513 . * @todo Support knurling of the dialhand protruding over the base shape. Cylinder(r = 8, h = shafthole_height, $fn = top_rounding_faces square(top_rounding_radius + pad, top_rounding_radius + pad); rotate_extrude(convexity = 5, $fn = top_rounding_faces square(top_rounding_radius + pad, top_rounding_radius + pad); rotate_extrude(convexity = 5, $fn = setscrew_hole_faces); // @todo Refactor the top_rounding() module. * @todo Add support for more shaft shapes (rectangular, gear shaped etc.). * @todo Some more "@todo" items as available inside the source code must retain the.
