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

With so much analog-circuit design being done by automated tools and circuit-performance analysis done with tools such as Spice, it may seem anachronistic to actually go through a basic circuit in ...

There have been many different ideas presented for increasing the acoustic output of a piezo buzzer or ultrasonic transducer. Most of them involve rather complicated circuitry that drives up the total ...

Electrical hazards can strike without warning—whether from damaged wiring, overloaded circuits, wet environments, or improper procedures. Understanding these risks and taking preventive steps is ...
