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 ...

So, I'm pretty handy with a soldering iron to put together stuff, but I have little to know idea of how to go about figuring out how to build a circuit. I mean, I know what a resistor does, and a ...

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 – ...

Electrical and electronic circuits are around us. From our mobile phones to security systems, electronic circuits are everywhere. Designing a circuit follows a step-by-step procedure. Most of the time ...

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 ...

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 ...

Accurate modeling of power electronic converters, i.e., obtaining control to output transfer function, must include series resistance of capacitors and inductors. A simple method allows measurement of ...

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 ...
