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 ...

Have you ever needed to power a 12-volt relay in a circuit but only had 6 or 9 volts available? This simple circuit will solve that problem. It allows 12-volt relays to be operated from 6 or 9 volts, ...

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

In the ongoing drive to make circuitry ever smaller and more powerful, researchers in Canada have taken things to a very small extreme. They devised a method for turning individual silicon atoms into ...

A simple circuit is a chain of different parts with wires and switches which allows electricity to flow around. All electrical appliances use circuits. For electricity to flow correctly, the circuit ...

We all carry supercomputers in our pockets and use dozens of electric gizmos every day but rarely stop to marvel at the magical act of flicking a switch. Use your ordinary conducting and extraordinary ...

Low-power circuits commonly use transformerless power supplies. However, the use of earth grounds in many of these circuits creates a serious problem that is often ignored. The very popular Microchip ...

Most circuits that require current loss detection use expensive isolation amplifiers. This circuit solves that problem with a simple and low-cost method to detect current loss of 4-20 mA. To view the ...
