Flexible printed circuits are useful when the size and shape of your invention is integral to its overall design. You've encountered them before − in mobile phones, cameras, and other increasingly ...

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 ...

Electrical and electronic circuits are around us. From our mobile phones to security systems, electronic circuits are everywhere. Designing a circuit follows a step-by-step procedure. Most of the time ...

Experimenting with batteries, bulbs, buzzers, switches and other electrical components is a great way to learn about circuits and start to think about how to incorporate sounds into your Build a ...

In the last installment of Circuit VR, we walked around a simplified buck converter. The main simplification was using a constant PWM signal. The result is that the output voltage is a fixed fraction ...

Chaotic circuits can arise from either computed (using Analog Computers or Digital Computers) solutions to coupled differential equations or from unstable systems/circuits. A new open-source circuit ...

There aren’t many things that are more impressive than a team of educated, confident, circuit-building Girl Scouts. In Denver earlier this month, Arrow Electronics participated in the second annual ...
