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?

“Measure twice, cut once” is great advice in every aspect of fabrication, but perhaps nowhere is it more important than when building a CNC machine. When precision is the name of the game, you need ...

Encoders are critical to the production of advanced electronics, one of the fastest growing and advancing industries in the world. Rotary, angle and linear encoders are all used in one form or another ...

Create a DIY ESP32 music player featuring Bluetooth and a brass rotary encoder. This guide covers soldering, custom code, and ...

An absolute rotary encoder determines the angular position of a shaft on the basis of a static reference point. They are sensors that generate digital signals that correspond to the position in ...

Why are there so many different angle encoders on the market? Why do they use different scanning and measuring methods? And which one should a designer choose? To answer those questions, engineers at ...

Linear guides support and control precision linear travel on axes in myriad machine and robotics types for modern automation. In linear-motion applications that are especially demanding, linear ...

An incremental rotary encoder converts angular motion or the position of a shaft to either analog or digital code. Incremental encoders are often used in feedback systems. These encoders translate ...

Encoders are a vital component in many applications that require motion control and feedback information. Whether a system’s requirement is speed, direction, or distance, an encoder produces control ...
