“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 ...

The RLT technology greatly improves brightness to LEDs with full red, green, blue and white color capability. Using a 4-color LED package allows the light output to be digitally control and produce ...

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 ...

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 ...

When it comes to developing faster computers, Intel has seen the light. The chipmaker recently launched a new effort inside its Microprocessor Research Lab aimed at examining a move from using ...

Light powers everything from communications to sensing, yet even tiny imperfections can scatter it and weaken signals. To address this, a team led by the University of Bath—working with the University ...
