[JRodrigo]’s xLIDAR project is one of those ideas that seemed so attractively workable that it went directly to a PCB prototype without doing much stopping along the way. The concept was to mount a ...

[Robi] and [Kathy] from elecfreaks have put together a how-to article about a Laser Piano they just built. Instead of keys, the user breaks beams of laser light to trigger the sounds. Several laser ...

An ESP32 firmware that measures distance with an ultrasonic sensor and displays it on a WS2812 LED strip — designed as a garage parking aid and as a learning project for embedded development with ...

A new laser range-finding technique, inspired by quantum physics, that can measure distances under strong solar background has been demonstrated by researchers at the University of Bristol. The team ...

Abstract: Black carbon (BC) aerosols, with their increasing emissions, have become a critical driver exacerbating global warming. However, the wide variety of atmospheric particulate matter poses ...
