Rotary potentiometers, switches, and encoders all share a basic design: adjustment is done via a shaft onto which a knob is attached, and knobs are sold separately. That doesn’t mean one knob fits all ...

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 ...

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 ...

PC gaming hardware maker Glorious’ latest product is a numpad and damn, it looks good. The GMMK Numpad is a wireless, mechanical ‘macro pad’ with tons of customization options, including a pressable ...

An inductive sensing based incremental encoder knob design can provide a robust and low-cost interface for control inputs. It can reliably operate in environments which have dirt, moisture, or oil ...
