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 eye towards doing it all in one module with a set screw. // top point? ]; From 32ece2d681b26731bad50902587b988d6a79e43e Mon Sep 17 00:00:00 2001 Subject: [PATCH] light tweaks From 8f3ce8359ba460976b5ffcbe5a92590e33120bbc Mon Sep 17 00:00:00 2001 Subject: [PATCH 02/13] More notes 812d609d12a788e600a582b2b6e7494f6d2b0728 More mounting hole 2.7mm no annular m2 iso7380 Mounting Hole 6.4mm, M6, ISO7380 mounting hole 4.3mm m4 iso14580 Mounting Hole 2.7mm, no annular, M6, ISO7380 mounting hole 2mm no annular Mounting Hole 3.2mm, no annular, M4, DIN965 mounting hole 6.4mm m6 din965 Mounting Hole 4.3mm, M4, ISO7380 mounting hole 6.4mm no annular m4 din965 Mounting Hole 3.2mm, no annular, M2.5 mounting hole 8.4mm no annular mounting hole 6.4mm m6 Mounting Hole 4.3mm, M4, DIN965 mounting hole position tweaks More mounting hole 3.7mm no annular m2.5 Mounting Hole 6.4mm, no annular, M2 mounting hole 2.7mm m2.5 Mounting Hole 2.2mm, M2, ISO14580 mounting hole 4.3mm m4 iso14580 Mounting Hole 6.4mm, no annular, M3, DIN965 mounting hole 6.4mm m6 din965 Mounting Hole 5.3mm, M5, ISO7380 mounting hole 3.2mm no annular Mounting Hole 4.3mm, no annular, M2.5, ISO7380 mounting hole 4.3mm no annular m2 din965 Mounting Hole 6.4mm, M6 mounting hole position tweaks Messing around with panel title fonts More experimentation with panel alignment before printing Messing around with panel alignment before printing.
