It's really surprising: it turns out that among simple electronic circuits, built of just a few components, many of them behave chaotically, in an extremely complicated, practically unpredictable ...

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 ...

It’s late at night. The solder smoke keeps getting in your tired eyes, but your project is nearly done. The main circuit is powered by your 13.8 V bench supply, but part of the circuit needs 9 V. You ...

Chaos Theory has been an important pursuit of physicists and mathematicians since it was brought to the forefront as a distinct phenomenon in the early 1960s. This early exposition got the attention ...

A very simple but highly efficient combination lock circuit is shown in the figure. Any type of on/off switches can be used, varying from commercially available inexpensive types to more sophisticated ...

I learned some basic electronics in high school physics class: resistors, capacitors, Kirchhoff’s law and such, and added only what was required for projects as I did them. Then around 15 years ago I ...

How do I learn circuit building and electronics on my Mac? If you want to learn about basic electronic components and how to build simple circuits, using your Mac as a learning resource, then you’ve ...

Team discovers fast, simple way to create two-dimensional electronic circuits that could potentially lead to a new generation of electronic devices. When Northwestern Engineering's Erik Luijten met ...

One tool erases frustration and boredom and makes electronics fun for students Very young students often have a hard time engaging meaningfully in electronics projects. Sure, most middle school kids ...

Impulse relay is a viable alternative for lighting control from multiple locations. In modernistic houses and apartments, lighting schemes to control lights from two or more locations are becoming ...
