Lumileds' second generation LUXEON CoB Compact Range LEDs feature an efficacy and output boost of up to 16% over its previous generation arrays. The devices cover different power range directional lamps such as a 35W-equivalent and a 50W-equivalent MR-16 lamp, achieving...

A Smart Night Lamp for kids. Tutorial and source code available: Few weeks ago I heard my nephew (aged 7) complaining of the dark at night. Basically he was afraid. So I decided to put knowledge into practice and build a night lamp for kids. Since the project was intended for kids, I...

Researchers have developed the first standard LED covering the full visible light, in collaboration with Nichia Corporation. LED and OLED lighting, which is generally called solid-state lighting (SSL), is becoming more common as the next generation lighting. Evaluations of...

Here is a 5 LED electronic candle using PIC12F508 able to power each LED with 20mA max. This candle produces a great effect and can be used either as a candle or inside a pumpkin. 5 channel LED candle using PIC12F508 -...

Jan Buiting @ elektormagazine.com discuss about a new technique used by scientist to build better LEDs. By manipulating the incident light, researchers of the Complex Photonics Group at University of Twente in Enschede, The Netherlands, have turned light propagating in a layer of...

In this article "Rui Santos" shows us how to configure Raspberry Pi as server and use it to toggle two LEDs over the internet. In this project you’ll create a standalone web server with a Raspberry Pi that can toggle two LEDs. You can replace those LEDs with any output (like a...

AughtNaughtZero @ instructables.com posted his latest project, a LED matrix visualizing data from a weather website such as temperature, pressure, humidity, wind speed etc. This project utilizes a 6 x 16 matrix of RGB LEDs to visualize a weather forecast pulled from the Weather...

Here is a LED matrix able to show useful information such as weather forecast, temperature and stock updates. The matrix is controlled by a Particle Photon board. You wake up in the morning. You're groggy. You grab your phone lazily and start browsing. You check the weather, your...
