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.

Efficient battery management becomes increasingly important as demand for portable power continues to rise, especially since balanced cells help ensure safety, high performance, and a longer battery ...

Why it's essential to combine sign-off accuracy, iterative feedback, and intelligent automation in complex designs.

Single-phase power factor correction (PFC) circuits—a kind of front-end AC/DC converters—are ubiquitous in a variety of ...

Long before perovskite solar cells began smashing efficiency records and transforming the future of clean energy, their ...

Intel’s 386 CPU is notable for being its first x86 CPU to use so-called standard cell logic, which swapped the taping out of individual transistors with wiring up standardized functional blocks. This ...
