Building simple circuits with copper tape, LED bulbs, resistors, and watch batteries is not as simple as you might think. Notre Dame Elementary School STEM students are putting the engineering design ...

The current-mode or peak-current-regulating switching converter is a familiar, almost dominant, power supply circuit consisting of few parts and is usually designed with “cookbook” procedures from PWM ...

The following is Part 1 of a four-part series. The basic one-op-amp differential amplifier consists of one op-amp and four resistors. Yet few have contemplated the depth of its complexity. It is ...

Testing for failure with a multimeter is only partially effective, whereas a dedicated optocoupler testing circuit provides ...

This animation shows how pairs of dangling bonds can serve as atom-sized binary bits in digital circuits. Credit: Robert Wolkow/U. Alberta In the ongoing drive to make circuitry ever smaller and more ...

Using simple components such as oil, salt water, lipids and proteins, plus routine genetic engineering techniques, it is possible to create simple nanofluidic ...

We all carry supercomputers in our pockets and use dozens of electric gizmos every day but rarely stop to marvel at the magical act of flicking a switch. Use your ordinary conducting and extraordinary ...

For electricity to flow, everything needs to be connected in a big ring. It’s called a circuit. For example, the lights in most houses and flats are part of a circuit controlled by the consumer unit, ...
