Now on Kickstarter nOb 

By intelligently emulating a Human Interface Device (NOT simply implementing a mouse scroll wheel), 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 features a big, solid, aluminium knob with adjustable rotation resistance and a very precise industrial grade encoder with up to 2400 ticks / revolution. All the electronics are housed inside a durable, hand crafted, hardwood mahogany enclosure. For those of you, who seek to make their own customizations, this can also be done. Its knob and toggle switches are touch sensitive allowing for some really neat productivity features, like e.g. double tapping the big knob to undo the last adjustment, touching the right toggle switch to temporarily flip the operation mode and many more!
