Do you ever find yourself wishing you had a little more control over your devices? Maybe you want to be able to change the volume or brightness without having to take your eyes off the screen. Or maybe you just want a more tactile input method. If so, then this DIY haptic input knob with a round LCD might be interesting for you.
In this video, Scott Bezek (scottbez1) demonstrates the results of his DIY project to build a haptic input knob with a BLDC motor and a round display. All of this has also been provided as an open-source library on GitHub, so you can check into the details and try this out yourself. There are undoubtedly some exciting use cases thinkable for such a potentiometer.
In the video description, Bezek shares some more details, “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!”
