When working around mains voltages, it can be useful to know whether a given circuit is live or not. While this can be done by direct connection with a multimeter, non-contact methods are available ...

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 ...

Working with circuits and LED lights guides students to test ideas, troubleshoot problems, revise plans, notice patterns, and ...

There is one analog graphic which remains impressive in spite of all the computer graphics programs available for screen savers and such. Known as quadrature art, the display can be produced with an ...

Using simple components such as oil, salt water, lipids and proteins, plus routine genetic engineering techniques, it is possible to create simple nanofluidic ...

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 ...

I will be talking about single-series (1sXp) cell configurations, for a simple reason – multiple-series configurations are not something I consider myself as having worked extensively with. The single ...

Sometimes a circuit requires a data link over an existing cable that doesn’t have any free conductors for a dedicated comm link. A common solution is to superimpose a high-frequency carrier modulated ...
