The digital volume control published in Elektor Electronics October 1997 can be used either with an RC5 remote control or with two pushbuttons (louder/softer). If for whatever reason you cannot do ...

This CircuitPython project adds a dedicated volume control to a PC using an Adafruit QT Py RP2040 and a Stemma QT Rotary Encoder. The rotary encoder adjusts the system volume, while pressing its ...

The other day we had a big problem. The Saddle feeder's speed control was done by a hydraulic device which consists of a wheel having a complete 360 degree rotation representing from zero speed to ...

You can create a release to package software, along with release notes and links to binary files, for other people to use. Learn more about releases in our docs.

One of the redeeming qualities of many modern cheap keyboards is the built-in volume control buttons. But this is Hackaday, and many of us (and you) have Model Ms or newfangled mechanical keyboards ...

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 ...

Rotary encoders are typicallyused in positioning systems withservo feedback in which the cost of theencoder usually is of minor importance.Encoders, however, are also usedin user interfaces to encode ...

The ChipEncoder(TM) uses a vertical cavity surface emitting laser (VCSEL) to generate a precise beam to reflect off a moving microetched scale onto a detector array beside the laser on the same hybrid ...
