Experimenting with an HF oscillator, I needed to control the varactor diode voltage in precise increments over a 2V-10V range. A buffered potentiometer was the obvious choice, and connecting two pots ...

[Long Haired Hacker] has undertaken a high-resolution 3D printer build. He got his hands on some motors to drive the build platform but it doesn’t have a built-in encoder. He knows that optical ...

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 ...

If you would like to add programmable controls via touchscreen and rotary dials to your existing project or next home automation system the M5Dial might be worth more investigation. Its interactive ...

Optical rotary encoders are the most widely used way to transform mechanical rotary motion into electrical signals. There are three basic configurations for optical encoders: incremental, absolute, ...

Motion-control or industrial automation system designers who need to measure the rotation of shafts or other mechanical components can typically choose from two types of rotary encoders. Encoders ...

HEIDENHAIN’s RENCO brand of encoders are well suited and available for use within a variety of mobile robot applications. Specifically, the modular RENCO R35i and RCML15 rotary encoders have proven ...

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 ...
