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 ...

[Geeksmithing] and [When Geeks Craft] recently came together for a glowing collaboration. They wanted to build ever more attractive lanterns for a local parade event. They recently discovered a ...

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 ...

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 ...

New year, new TV? That's a great plan! It might be tempting to wait for the new 2026 models, which will be announced in the coming days and weeks, but it's never a good idea to buy a TV when it first ...

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 ...

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 ...

This is an Arduino project for controlling addressable LED strips (WS2812B) with an ESP32, designed for seamless integration with Home Assistant via MQTT. It provides a flexible effect system that ...

this application is a companion to my hardware led controller that drives addressable leds from an artnet network connection. it was built for lateral movement club nights such as seen here: you can ...

Abstract: Content Addressable Memories (CAMs) match input data to stored content, ideal for search-intensive tasks like network address lookup and similarity matching. This paper explores CAM ...
