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 ...

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 ...

This video explains the function of diodes and how they are used to control the flow of electrical current in electronic ...

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 ...

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 ...

This video provides a clear explanation of resistors and their role in electronic circuits. It introduces the principles ...

Here is a great collection of touch switch circuits. A touch switch is an electronic device that enables us to control a circuit by simply touching a sensor. Simple touch switch circuit with 4011 – ...

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 ...

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