Total mastery over the pinout and functionality of the PCA9306 for conversion of logic levels from 5V to 3.3V. A step-by-step interfacing diagram for the PCA9306 to Arduino UNO. Working example with ...

It's double-barreled, it uses lasers instead of LEDs, and it's machined from a solid block of 6061 aluminum alloy. Come meet the Lumitwin DL700 flashlight, which belts out two converging beams up to 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 ...

The Creality Falcon A1 Pro arrived well-packaged with protective foam securing every component during shipping. The machine comes nearly fully assembled, requiring ...

Saudi Arabia's high-tech gamble on Chinese laser weapons is faltering. In a bid to shield vital oil facilities and billion-dollar Patriot batteries from drone swarms, Riyadh turned to China's ...

Laser engraving has always been about power and precision, but for years, most desktop engravers asked creators to make compromises. You can gain speed, but you lose accuracy. You could get power, but ...

In this Arduino project, I show you how to build a simple servo laser tower controlled from a smartphone app called Blynk. This is ideal for making a toy for your cat or dog. #ArduinoProject #CatLaser ...

Resonantly tunable quantum cascade lasers (QCLs) are high-performance laser light sources for a wide range of spectroscopy applications in the mid-infrared (MIR) range. Their high brilliance enables ...
