Includes weird 8V linear regulator for the articles that helped implement this. Ct = -0.1; // circle translate? Not sure. Circle_radius = knob_radius_top; // just match the height about right. It's easier to adjust CV output range, switch between 5v and 2.5v max (or whatever is configured). Momentary-normal-off pushbutton to manually reset. LEDs: One per step, to set output voltages. (10) One potentiometer for internal clock signal (possibly external). Commonly called a "Baby 8". 0 0 Dual VCA, based roughly on Moritz Klein's work, but with an eye towards doing it all in one module with WiFi, https://www.adafruit.com/product/2471 Arduino UNO R2, http://www.mouser.com/pdfdocs/Gravitech_Arduino_Nano3_0.pdf Arduino UNO R3, http://www.mouser.com/pdfdocs/Gravitech_Arduino_Nano3_0.pdf 8devices Carambola2, OpenWRT, industrial SoM computer, https://www.8devices.com/media/products/carambola2/downloads/carambola2-datasheet.pdf Pololu Breakout 16-pin 15.2x20.3mm 0.6x0.8\ Raspberry Pi Zero using through hole 4.5mm, height 2, Wuerth electronics 9774050960.
