Designed by Cirket open-source hardware in China, the ESP32-DIV V1 is a handheld wireless pentesting and experimentation tool ...

Here’s a fun build from [RootSaid] that is suitable for people just getting started with microcontrollers and robotics — an Arduino-controlled two-wheeled robot. The video assumes you already have one ...

What doesn’t this Arduino Mega shield have? Ponder that as you realize that it doesn’t just attach itself to the pin headers, but uses every single one of the mega’s connections. This isn’t a bunch of ...

Dermatologists explain the science behind wildly popular treatments like red light therapy, which is now available at home—for a steep price. Full-face LED masks like this one can cost up to several ...

Scientists have uncovered the mystery of why blue light-emitting diodes (LEDs) are so difficult to make, by revealing the complex properties of their main component -- gallium nitride -- using ...

It turns out the "10-year lifespan" printed on your LED box is often a total fantasy. I spent years falling for the marketing, only to end up standing on a ladder every six months replacing bulbs that ...

Organic LEDs are light emitting diodes (LEDs) that use polymers or small organic molecules as their optically active element. Development of organic LEDs is driven in particular by its potential as a ...

More than one-fifth of US electricity is used to power artificial lighting. Light-emitting diodes based on group III/nitride semiconductors are bringing about a revolution in energy-efficient lighting ...

The nighttime twinkling of fireflies has inspired scientists to modify a light-emitting diode (LED) so it is more than one and a half times as efficient as the original. Researchers studied the ...

The MS-PC Farm 88601 supports four DDR5 slots for 256GB maximum memory PCIe 5.0 x16 interface allows high-end graphics cards to operate fully 10+1+1 phase SPS power design provides stable CPU ...
