CKnob
A premium, handcrafted multimedia USB controller with a real concrete knob: volume, scroll, video seek and shortcuts, in one.
01
What it does
- Volume controller
- Page scroll, mouse-wheel style
- Video forward and reverse
- Custom shortcuts
02
Concrete on a steel bearing
The distinctive feel is genuine concrete weight suspended on a precision steel bearing — that is where the exceptionally smooth action comes from. Four rubber pads keep it in place while you work.
03
Light underneath
The levitating impression comes from an LED ring beneath the knob, fully colour-customisable to fit your setup.
04
Plug and play
CKnob is a completely plug-and-play, Arduino-based device. Set it up in the browser — no driver, no install.
05
Scarlett
The Scarlett version brings a signature colour and a dark metal-oxide concrete finish, with a brutalist touch. Same device underneath.
06
One knob to rule them all
Whether you scroll through pages and screens mouse-wheel style, seek through video, or ride the volume — it is one knob. A data USB cable is not included.
