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 ...

This project features an under-the-desk-style volume mixer with six rotary encoders for controlling individual audio channels on your PC, a display for visual feedback, and an air quality sensor that ...

一日で一番手に触れているものはキーボードという思い込みから、不便さを克服することにより得られる快楽を毎日満喫するために小さなキーボードの導入を思い立ち、2022年12月にClaw44の購入を決意。プログラミングと自作キーボードの知識ゼロから始めた ...

Abstract: This article introduces a low-power spintronic rotary encoder capable of 8-bit analog-to-digital conversion. The proposed encoder leverages spin-Hall effect-driven domain wall motion ...

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 ...

Touch screen head units are pretty much the norm these days. Many compromise with annoying on-screen volume controls or tiny buttons. If you find yourself with such a unit, you might like to hack in a ...
