A continuity tester that indicates the resistance of, say, PCB traces with musically-related tones, whose pitch changes with ...

Inductors are simple coils of wire, but they play a powerful role in managing electrical current. This video explains how ...

Using ultracold atoms and laser light, researchers recreated the behavior of a Josephson junction—an essential component of ...

Single-phase power factor correction (PFC) circuits—a kind of front-end AC/DC converters—are ubiquitous in a variety of consumer electronic devices, including laptop adapters, LED driver power ...

For granulators and shredders to be truly user-friendly, they have to prioritize safety, ease of maintenance, and simple ...

While standard receptacles typically use three wires -- hot, neutral and ground -- you'll occasionally find 2-prong outlets in older homes. Since this type of outlet lacks a ground connection, the ...

Exploring DAC control of a regulator while ignoring the many possibilities for integrating its internal voltage reference into the design.

Cell-sized robots can sense temperature, make decisions, and move autonomously using nanowatts of power—no external control ...

Each robot costs only a single penny to manufacture. The robots could help advance everything from nanotechnology ...

Interposers are effectively platforms on which multiple components can be assembled — like a micro-sized PCB. The primary material today is silicon, and their sizes, even when built on older process ...
