This custom linear Hall effect sensor is a perfect example ... a long way to go to tighten things up, but the basic mechanism looks like a clear win to us. Hats off to [Nixieguy] for this one ...

Each unit is scratch-built, using laser-cut fiberboard for parts like the spool and frame ... four stepper drivers and interfaces for the Hall-effect sensors needed to home each display.

A team of researchers led by Colorado State University graduate student Luke Wernert and Associate Professor Hua Chen has ...

Not only are Hall-effect sticks more reliable over time, they can provide more precise inputs. Many traditional analog sticks, like those in modern controllers from Nintendo, Sony, and Microsoft ...
