A solar day lamp is a simple, inexpensive device for bringing “daylight” to dark interior spaces whenever the sun is shining. This article provides complete instructions for designing lamps using both ...

Traditional sonar and radar use an echo-based approach, and have been amazingly successful in sensing and tracking vehicles and objects under water, through the air, or even in space. The principle is ...

When first learning about and building electronic circuits, the first things all of us come across are passive components such as resistors, capacitors, and inductors. These have easily-understandable ...

Active inductors have emerged as a transformative component in CMOS radio frequency (RF) circuit design, effectively replacing traditional passive inductors with active semiconductor networks. By ...

That’s the list. Those are your passive components. Well, it’s not that easy. Also add in a bunch of types of sensors, because they are still passive. A photoresistor is a sensor but it’s still a ...

This file type includes high-resolution graphics and schematics when applicable. While semiconductors and software continue to expand the capabilities of electronics products, a new kind of passive ...
