The nOb is a precise generic endless knob controller, being produced via a Kickstarter campaign.
The controller was designed for fine control of any type of parameter during media production.
Here’s the official intro video:
Here’s what the developer has to say about it:
nOb is able to control virtually any parameter you would normally adjust with your mouse, delivering out-of-the-box compatibility with any operating system and software package. You simply have to point your mouse cursor to the parameter you want to control and use nOb’s big knob to fine-tune it to taste. Based on the current mode of operation, any draggable interface element found in modern media production software can be controlled, including sliders, scrollbars, knobs or even draggable value indicators.
nOb is available to backers for approx €165. See the project site for details.
