Is it really possible to build a rotary encoder out of a flattened tin can and a couple of photodetectors? Sure it’s possible, but what kind of resolution are you going to get from such a contraption?

3D printed holder mounted to bike wheel, fitting precisely 38 magnetic spheres around its perimeter. Tedious math? Not if you make OpenSCAD do it. Off-the-shelf components are great; the world and our ...

Rotary and linear optical encoders are common in position and motion sensing. Here, a disc or plate containing opaque and transparent segments passes between an LED and detector to interrupt a light ...

This file type includes high resolution graphics and schematics when applicable. Rotary encoders track motor shaft movement for myriad pieces of industrial equipment and commercial devices. For ...

Rotary encoders convert rotary movement or angular position into analogue or digital signals for use in measurement or control systems. They can be classified in a number of ways, primarily by the ...
