A Knob you can twist as much as you like.
The Ploopy Knob is a stand-alone dial that runs QMK and can be programmed to do anything you want. With a smooth feel and great finish, it’s a Knob you’ll want to touch all day long.
High-res scrolling. It’s a really sensitive Knob.
The Knob features high-resolution scrolling, right out of the box. You’ll get smooth, pixel-by-pixel scrolling for a buttery-smooth scrolling experience.
Many functions. One Knob.
High-resolution scrolling
Out of the box, the Knob functions as a high-resolution scrolling device, for tight control over any program.
Media control
The Knob can be reprogrammed to serve as a media controller. Volume can be smoothly adjusted, media can be rewinded or fast-forwarded, tracks can be replayed or skipped, and so much more.
Creative control
The Knob is a great addition to any creative workflow. The high-resolution scrolling is highly useful, and can also be reprogrammed to accommodate other needs, like inputting key commands repeatedly.
Any other function
If none of the out-of-the-box solutions work for you, you can program your own, for ultimate customization.
A Knob that looks as good as it feels.
The Knob has an incredible textured finish. It will look as good as it functions, wherever you decide to put it.
3D-printed. Your way.
3D-printing means more possibilities
Of course, you’re not just limited to our case colour. Since the Knob is 3D-printed, you can print a Knob as unique as you.
Ultimate maintainability
If any part breaks, it’s easy to print out replacements, using any 3D-printer and using our open-source design files. That means a longer lifespan for your Knob.
Of course, open source.
Everything is open-source
Source files for STEP files, PCB design files, firmware, and everything else are available, for free, forever, without any limits.
Radical transparency
We believe in giving our supporters all the information to make informed choices. That’s why we are committed to full transparency on parts, fabrication methods, and how it all works.
