Knobs are ubiquitous in technology user interfaces, but touchscreens are increasingly replacing them for interface controls. The latest project from [upir] combines a rotating knob with a touchscreen ...

The scroll wheel might be the best thing that happened to the computer mouse since, well, the computer mouse. But sometimes you want something a little more tangible. For example, with a ...

Microchip has introduced a touch controller family for ‘knob-on-display’ (KoD) human-machine interfaces. These interfaces add a physical ‘clicky’ knob to the front of a display without traditional ...

A line of knobs for encoders and switches features bell- and top-hat-shaped 16-mm parts. Available in soft-touch or hard plastic designs, the knobs accept standard D-shaped 6-mm shafts. Blue or white ...

Touchscreens and touchpads haven’t totally taken over the human-machine interface (HMI) function and many situations still exist where discrete switches or even the classic QWERTY keyboard remain the ...

I want to write about something a little different this time. I removed the mechanical scroll wheel rotary encoder from a discarded optical mouse and used it in a little project. I really liked the ...

In a nutshell: Canadian hardware maker Ploopy is now accepting pre-orders for its latest input device. The Ploopy Knob is a 3D-printed, open-source rotary encoder featuring a high-precision sensor ...

Rotary quadrature encoders often are used to command digital potentiometers or digital controllers, and quadrature decoding is typically performed in a programmable device (like an FPGA or ...
