Radio experimenters often need a variable capacitor to tune their circuits, as the saying goes, for maximum smoke. In decades past these were readily available from almost any scrap radio, but the ...

In high-stakes applications like EV battery development, even minor measurement drift can lead to major consequences.

In part 1, we examined the operation of power supply supervisory ICs that can detect when the supply voltage is too low, and ...

In this video, a vintage 50-year-old Rockwell hardness tester, weighing over 80kg (176lbs), is restored. The machine employs mirrors, translucent scales, and old-style light bulbs to measure hardness ...

Learn why high-voltage environments require advanced testing tools—and how engineering teams maintain measurement integrity under demanding conditions.
