This resource provides clear explanations of how switching regulators work and how voltage boosting is achieved efficiently ...

The first thing I ever built without a kit was a 5 V regulated power supply using the old LM309K. That’s a classic linear regulator like a 7805. While they are simple, they waste a lot of energy as ...

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

Replacing the traditional wire complexity with Flexible printed circuits provide a unique medium for electric circuits. Flexible Circuit Technologies are produced by photolithographic technology. A ...

Illustrated in this simple project is the creation of an Easy Dub Siren from a Circuit Bent Keychain along with a bunch of components. The parts that would be needed to build the Easy Dub Siren ...

The creative new approach could lead to more energy-efficient machine-learning hardware. On a table in his lab at the University of Pennsylvania, physicist Sam Dillavou has connected an array of ...
