An Arduino-based smart-home prototype that integrates environmental sensors, user input, display modules, LEDs, a buzzer, a DC fan, and servo-controlled doors/windows into one rule-based embedded ...

Passive InfraRed sensors (PIRs) are electronic devices which are used in some security alarm systems to detect motion of an infrared emitting source, usually a human body. All objects, living or not, ...

It’s little secret that stepper motors are everywhere in FDM 3D printers, but there’s no real reason why you cannot take another type of DC motor like a brushless DC (BLDC) motor and use that instead.

Robots are cool, so check out [Atlin Anderson]’s Spiderbot (video, embedded below) which can be made with 3D printed parts, hobby servos, and ESP32-CAM module for control and a first-person view.

Researchers from the Molecular Physics and Physical Chemistry departments of the Fritz Haber Institute have shown how two highly synchronized infrared (IR) laser beams can control molecules as they ...

Researchers have developed a tiny, electrically tunable infrared filter that could help shrink bulky thermal sensing systems onto portable chips—a technology that could lead to handheld pollution ...

The Terrain Commander from Textron Corporation provides the basis for the U.S. Army's unattended ground sensor (UGS) Future Combat Systems. The sensor assembly is equipped with a variety of optical, ...

Infrared saunas have become incredibly popular, even though they aren’t really saunas at all. To the untrained eye, they basically look the same as what you’d expect a sauna to look like—wood paneling ...
