Smartknob
Smartknob is an open-source programmable rotary interface platform that combines motor-driven feedback and sensor-based tracking to provide tactile input for digital environments. It functions as a customizable input device peripheral, utilizing a brushless motor and a magnetic encoder to translate physical rotation into precise control signals for software applications.
The platform distinguishes itself through software-defined haptic feedback, which allows for the simulation of physical sensations such as clicks, springs, and hard stops. By employing closed-loop control and real-time motor commutation, the system generates dynamic resistance and virtual detents that can be configured to match specific interaction requirements, effectively emulating mechanical switches without the need for complex physical hardware.
The project provides a comprehensive framework for custom hardware prototyping and haptic controller assembly. It includes guidance for mechanical and electronic integration, such as magnetic encoder alignment and modular mounting adapters, to ensure consistent performance across diverse motor and sensor configurations.
