Controllers with Hall effect technology have been gaining ground in recent years, and for good reason. They offer greater ...

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 ...
