Ploopy Knob, a high-precision controller for scrolling websites and finer tasks, has been unveiled
Canadian company Ploopy has released Ploopy Knob, a compact and highly accurate controller aimed at developers, designers and enthusiasts who need a precise and customisable tool to control volume, scrolling, media functions and parameters in professional editors.
Here's What We Know
At the heart of the device is the AS5600 magnetic encoder, which offers 12-bit resolution and accuracy down to 0.088°, allowing for 4096 discrete rotary positions. This makes the Knob particularly useful for applications requiring fine-tuning.
The Ploopy Knob is built on a 125MHz RP2040 microcontroller and runs QMK firmware, which supports programming everything from scrolling and volume control to running macros and repetitive commands.
The device is compatible with Windows, Linux and macOS, although macOS lacks support for high-precision scrolling due to the limitations of the USB implementation.
The body of the Knob is 3D printed, allowing for easy design modifications, replacing parts when needed and customising the device to suit individual preferences. The design utilises a 6705ZZZ bearing, providing smooth, backlash-free rotation with a pleasant tactile feel.
The unit weighs only 31 grams and measures 56×17mm, making it convenient for desktop use and portability.
All source files - from schematics and firmware to STL models - are publicly available on the GitHub page.
The Ploopy Knob is priced at $49.99 CAD ($36-37 USD). The device is available for pre-order on the official Ploopy website.
