Hackers and makers can sometimes feel like they’re getting the short end of the stick when it comes to gift giving. You’re out there making thoughtful, intricate circuit sculptures, helpful software, ...

There have been many questions about what direction Arduino would take after being bought by Qualcomm. Now it would seem that we’re getting a clearer picture. Perhaps unsurprisingly the answer appears ...

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 ...

Lasers, LEDs and light sources are devices that create light. LEDs (light emitting diodes) convert an electrical current into light using spontaneous emission in optically active semiconductors.

If you are on the hunt for a TV with a price tag that will not break the bank, it can feel like quite an impossible task. After all, there are countless models with discounted price tags to be found, ...

Abstract: We propose an optical camera communication (OCC) system with dimming control, employing wavelength division multiplexing (WDM) with RGB and infrared (IR) light sources. The system uses pulse ...
