Elektor Magazine, January & February 2026 (Issue 543)

Power design is the thread running through this January–February 2026 issue of Elektor Magazine. Issue 543 brings together hands-on circuit projects and technical features, from a low-noise analog lab supply to lithium battery technology, energy harvesting, and power for connected devices.

The articles balance practical builds with explanations of the engineering behind them, making this a varied read for electronics makers and professionals interested in how power systems are designed, measured, and improved.

Power projects for the workbench

The issue opens with a low-noise laboratory power supply designed for sensitive circuits. Other projects include an adjustable electronic load that supports static and dynamic DC loads, a graphical grid-frequency meter, and an adjustable USB-C power source. Together, they explore useful ways to supply, test, and monitor electrical systems.

Batteries, energy, and connected devices

“Batteries Today” examines lithium battery technologies and their differences. Elsewhere, features look at energy harvesting for IoT and IIoT applications, a battery monitoring system, and wireless device power using inductive technology. These articles connect component-level choices with the demands of real electronic applications.

More than power supplies

Additional coverage ranges from a step-down converter and an autonomous sensor node to a smart color detector with AI-generated voice and an article on AI-based autonomous driving. The issue also presents the winners of the STM32 Edge AI Contest 2025 and reviews the Fnirsi DPS-150 compact power supply and converter.

For curious electronics builders

With circuit projects, technical features, a product review, and regular magazine departments, this issue offers plenty of entry points for readers who enjoy understanding how electronics work—and putting that knowledge to use at the bench.
