MSI motherboards use light-emitting diodes to report the status of the computer. Most computers have an LED for the power and an LED for the hard drive. If the PC is turned on, the power LED glows ...

A few years ago, the highest power LEDs you could buy capped out around three watts. Now, LED manufacturers are taking things to ridiculous power ratings with 30, 40, and even 90 watt LEDs. Getting ...

Firstly, what output voltage is the power on LED motherboard headers? 3.3,5,12? Secondly, how many LED's could it take in parallel for more than one indicator lit at the same time? Three okay? (if not ...

Driver circuits are available in a variety of topologies. These include series (switch-mode) drivers, and parallel (non-inductor) drivers. How LEDs are driven depends on the level of efficiency ...

Long used in instruments and computers as visual indicators for signal integrity and operations status, LEDs are ideal choices due to their high reliability, low power use, and ...

But there’s a problem with this idea. First, the resistor will possibly dissipate a large amount of power. For instance, a resistor used to drop 12 V (a common voltage used for halogen task lighting) ...

Recent breakthroughs in LED technology have enabled LEDs with a broad spectrum of light output to be produced and not just the traditional red and green derivatives. Hence the sheer numbers of LEDs ...

Researchers at Ben-Gurion University of the Negev have demonstrated a novel way to spy on electronic conversations. A new paper released today outlines a novel passive form of the TEMPEST attack ...
