A blast from the Elektor archives: this 1998 battery tester uses a simple LED display to reveal a battery’s true condition under load — even below 1 V.
Discover how to build a simple wireless power transfer system at home using readily available components like enameled copper wire, an LED, a 2N2222A transistor, and a 9V battery. This step-by-step ...
By combining psilocybin with a modified rabies virus that tracks neural connections, they mapped how networks change after a ...
Single-phase power factor correction (PFC) circuits—a kind of front-end AC/DC converters—are ubiquitous in a variety of ...
Microscopic fibers secretly shape how every organ in the body works, yet they’ve been notoriously hard to study—until now. A new imaging technique called ComSLI reveals hidden fiber orientations in ...
Researchers in Sweden have unveiled a way to create high-performance electronic electrodes using nothing more than visible light and specially designed water-soluble monomers. This gentle, ...
LED Christmas lights may be efficient, but can you use them worry-free? We talked to an expert about how proper usage and ...
Visible light can be used to create electrodes from conductive plastics completely without hazardous chemicals. This is shown ...
The microscopic processes taking place in superconductors are difficult to observe directly. Researchers at the RPTU ...
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 ...
