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?

Knob controllers can control volume settings, scroll through web pages, and help edit movies among other uses. You can buy a commercial one from Griffin Technology for $45 or build one yourself with ...

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 ...

Edited by Zak Khan || It may seem as though linear encoders and rotary encoders have strictly defined (and maybe even mutually exclusive) applications. Prevailing logic is that linear encoders track ...

Rotary encoders connect to a shaft and, as the shaft rotates, the encoder outputs pulses. These are used to determine the speed of the object. By counting the amount of pulses per one full turn of the ...
