“Slim as a hair, powerful as 100 LEDs”: the advantages of this technology have the allure of a slogan. “Currently, half the consumption of energy in laptops is connected to the screen and particularly ...

[Peter] has finished up his fiber optic microscope light source. When we last visited [Peter] he created a dimmer circuit for a 10 watt LED. That LED driver has now found its final home in [Peter’s] ...

[Brainiac75] is a fan of fiber optic lamps, except for one thing—they’re often remarkably dim. Thus, they set out to hack the technology to deliver terrifying amounts of light while still retaining ...

Scientists have, for the firsts time, been able to make a practical optical fiber with a silicon core. Scientists at Clemson University for the first time have been able to make a practical optical ...

Many Ars readers love to argue the details of different computer architectures. Cache implementations, pipelines, and other minutiae are all put under the microscope and declared wanting by someone ...

The circuit in Figure 1 allows you to verify fiber-optic strands, especially in cases in which a link goes through several patch panels. It uses two high-intensity LEDs that you can see at the far end ...

The “Lit” concept bulb designed by Elie Ahovi is an extremely elegant and innovative combination of LED and fiber optic technology, and could pave the way for incandescent replacements of the future. ...

It seems graphene, the single layer of carbon atoms that can supercharge computer chips, optical circuits, lithium-ion batteries, and solar power generation, might have a competitor: a rare earth ...

The product is an active optical cable (AOC) for HDMI. Instead of relying solely on copper, it carries most of its signal over fiber-optic strands. Inside ...
