# Dedicated PC Control Knobs The Ploopy Knob Works for Volume Control, Scrolling and More By Michael Hemsworth | Published 2025-07-05 | Tech Source: Trend Hunter, https://www.trendhunter.com/trends/ploopy-knob References: [theverge](https://www.theverge.com/news/698443/ploopy-knob-dial-peripheral-controller-open-source-qmk) & [ploopy.co](https://ploopy.co/shop/knob/)  The [Ploopy](https://www.trendhunter.com/trends/ploopy-bean) Knob has been announced by the brand as a [control dial](https://www.trendhunter.com/trends/mx-creative-console-1) for use with a PC as an open-source way to intuitively navigate the interface, make system adjustments and more. The simple peripheral comes in the form of a circular knob that can be used for [adjusting volume](https://www.trendhunter.com/trends/scroll-the-volume), scrolling through documents, scrubbing through media and more. The knob has a 3D-printed construction with a high-precision sensor inside that will work effectively right out of the box. The Ploopy Knob is powered by a Raspberry Pi RP2040 microcontroller and uses a position sensor with a 12-bit resolution, while also offering a polling rate of more than 1kHz for tracking rotational movements. This means users can enjoy pixel-by-pixel scrolling when being used on Windows and Linux systems.
