Play dough circuits 2: experiment with electricity Last time, we went through the basics of how to make simple electrical circuits with play dough and light-emitting diodes, now it's time to ...

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 ...

This design shows how a piezoelectric transducer's acoustic output can be increased while minimizing the parts count and cost.

Simple electrical circuits are super cool, but simple series and parallel circuits are just the foundation of the much, much more complex circuits used in modern electronics.

Although this circuit connects the DS18S20 1-Wire temperature sensor to a Cypress CY8C26443 PSoC microcontroller, designers can easily adapt it to connect other 1-Wire devices to any microprocessor.

A simple circuit uses one control device to control bass and treble simultaneously, with a symmetric response that is flat at the center of the adjustment range.
