Building simple circuits with copper tape, LED bulbs, resistors, and watch batteries is not as simple as you might think. Notre Dame Elementary School STEM students are putting the engineering design ...

In this video I’m showing how I’ve built a very simple battery backup circuit for my home alarm system. The circuit charges a 12v lead acid battery and in an event of a power loss, it transfers the ...

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 ...

This animation shows how pairs of dangling bonds can serve as atom-sized binary bits in digital circuits. Credit: Robert Wolkow/U. Alberta In the ongoing drive to make circuitry ever smaller and more ...

Simple Sound Processor presented here is an ultra-simple circuit module suitable for almost all basic electronics and microcontroller projects. For example, this module can be used as a front-end in ...
