Rotary potentiometers, switches, and encoders all share a basic design: adjustment is done via a shaft onto which a knob is attached, and knobs are sold separately. That doesn’t mean one knob fits all ...

[Mitxela]’s repair of a Roland JV-1080 (a rack-mounted 90s-era synthesizer) sounds simple: replace a broken rotary encoder on the front panel. It turned out to be anything but simple, since the part ...

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 ...

What is a rotary encoder? A rotary encoder (RT) is a device that you can rotate infinitely. On most rotary encoders, when you rotate them you will feel a bump (known as steps), and most RTs have about ...

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 ...

I want to write about something a little different this time. I removed the mechanical scroll wheel rotary encoder from a discarded optical mouse and used it in a little project. I really liked the ...

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 ...
