# SmartKnob # SmartKnob
SmartKnob is an open-source input device with software-configurable endstops and virtual detents.
Coming soon... A brushless gimbal motor is paired with a magnetic encoder to provide closed-loop torque feedback control, making it possible to dynamically create and adjust the feel of detents and endstops.

A mediocre choice. Cheap breakout boards are readily available.
In my testing, it's fairly noisy (anecdotally, noisier than the TLV493d), requiring filtering/smoothing that can slow responsiveness, hurting control loop stability. Additionally, it saturates at a lower magnetic field strength than other sensors I tested, requiring a significant air gap (8-10mm) when used with a strong neodymium diametric magnet like [Radial Magnets 8995](https://www.digikey.com/en/products/detail/radial-magnets-inc/8995/5126077).
