DIY haptic input knob: BLDC motor + round LCD

Very cool demo of DIY haptic control. Not a lot of specifics in the video, but the project is open source -- check the description.

Introducing the SmartKnob View: an open-source input device with software-configurable endstops, virtual detents, haptic touch feedback, and a round LCD.

Since you can't feel the detents through the video, make sure to turn up the volume so you can at least hear them, particularly the fine-grained detents toward the end of the video.

A brushless gimbal motor is paired with a magnetic encoder to provide closed-loop torque feedback control, enabling virtual endstops and detents. Internally, everything is powered by an ESP32, with a TMC6300 BLDC motor driver, HX711 strain gauge ADC, VEML7700 ambient light sensor, and more!
