Researchers are learning to flip light on and off one particle at a time, turning single photons into a controllable resource instead of a random byproduct of exotic materials. By engineering ...

With just three transistors, one relay, and some resistors and capacitors, a single light switch can provide sophisticated control of high-power and low-power lamps. With just three transistors, one ...

This light activated remote switch circuit could be operated using a flashlight beam and could eb used for toggling a specified load from a distance using an external light source such as a flashlight ...

Brilliant’s screen-based smart light switch has incredible aspirations, but some kinks still need to be ironed out. In the early days of the smart home, few could have predicted that one of its ...

Which smart light switch is best? Smart technology offers convenience and efficiency at every turn, and smart light switches are no exception. The ability to control light switches either by app or ...

Being compatible only with single-pole switches in single-gang boxes are big limitations, but the SwitchLight is an otherwise terrific addition to any home’s lighting controls. As with the Safelight, ...

Electronics keep shrinking, but silicon is starting to run into physical limits. To go smaller, researchers are turning to ...
