LED lights typically last far longer than their incandescent predecessors. If your bulbs are failing early, these are the ...
Tattoos. Body paint. Henna. All these are popular kinds of body art with varying histories and cultural connotations, many ...
Abstract: A new high-speed low-power logic circuit using Schottky barrier diodes to avoid saturation of bipolar transistors is described. An experiment using discrete devices and a theoretical ...
Scientists in China have created a new type of display with the smallest pixels and the highest pixel density ever.
That means inside every LED bulb are tiny circuit components — and their soldered contact points — which are far more vulnerable than the diode itself. The Lighting Research Center of the ...
Her talk concerns rethinking body art with the use of light emitting diodes—and is both thoroughly modern and aesthetically compelling. Beyond that, it’s an engineering development story with ...
This paper introduces a novel high-sensitivity readout circuit that leverages the resonant amplification effect of the LC network in an oscillator to generate high-voltage excitation signals. By ...
Is it a costly, but clean, power supply? Or a noisier, less expensive, and lower-loss design? Or (gulp) something even more ...
It looks like an adaptor and it kind of is. But this cult fuzz box was a favorite of Norman Greenbaum and Spirit’s Randy ...
Physicists have created the tiniest light-emitting diode (LED) displays ever 1. The image above was shown on a monochromatic display with pixels less than 100 micrometres across, about the width ...
The humble yet ubiquitous infrared remote-control receiver can benefit from an enhanced front-end preamplifier.
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 ...
