PHILADELPHIA — The technological world of the 21st century owes a tremendous amount to advances in electrical engineering, specifically, the ability to finely control the flow of electrical charges ...

The rise of low-cost, hacker-friendly electronics is fueling a new wave of hardware hobbyists. Using programmable boards like the Arduino and dirt-chip computers like the Raspberry Pi, you can build ...

Q: Several weeks ago, I read your column about installing electrical wiring. I’m curious about circuit breakers. What is the primary purpose of circuit breakers? Are there different types of breakers?

The advent of microcontroller modules like the Arduino opened up ability to build and program interactive objects to a whole generation of makers. Today these modules make it simple to control ...

If computers calculated using light instead of electrons, they’d be more energy efficient and at least a thousand times faster than they are today. Unfortunately, the optical analogs of computer ...

In many ways, life is like a computer. An organism's genome is the software that tells the cellular and molecular machinery -- the hardware -- what to do. But instead of electronic circuitry, life ...

We started out with an old modem and ended up with a useful circuit to convert phone audio to regular line audio. This little hack is useful for those of us wanting to record Voip telephone calls for ...

A team of University of Arkansas physicists has successfully developed a circuit capable of capturing graphene's thermal motion and converting it into an electrical current. "An energy-harvesting ...
