These light up paper circuit cards were much easier to make than I expected and only need a few inexpensive materials.

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.

Abstract: By combining the conventional switched-mode power converters with advanced switched capacitor (SC) techniques, a plurality of single-switch current-balancing circuits is developed to drive ...

By combining psilocybin with a modified rabies virus that tracks neural connections, they mapped how networks change after a ...

H-bridge buck-boost ICs are widely used in applications requiring a constant voltage or current source even when the system ...

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 ...

Former University of York graduates Thomas Mason and Jack Clarke have unveiled their first product under their York-based EdTech company, HYEN. Sticky Circuits: Christmas Tree Edition is a hands-on ...

Abstract: This paper proposes a new current balancing method for alternating current (AC) - light emitting diodes (LED). The proposed method uses the bi-directional current mirror circuit with ...
