We all carry supercomputers in our pockets and use dozens of electric gizmos every day but rarely stop to marvel at the magical act of flicking a switch. Use your ordinary conducting and extraordinary ...

In Part 1 of the Electronics for Kids series, we looked at LEDs; in Part 2, we explored capacitors; and in Part 3, we took an in-depth look at electrical measurements. In this article, we will focus ...

These light up paper circuit cards were much easier to make than I expected and only need a few inexpensive materials. They're a great way to learn about ...

Linear constantcurrent drivers, for instance, offer low EMI, low cost, and use only a few components. Many designers favor them for low-current applications where power loss is a minor concern. If ...

Among the abundance of components making up electronic circuits, very few are as important as capacitors. These components, taking the form of conductive plates separated by an insulating material ...
