The circuit diagram illustrates the creation of a plain microphone setup using two resistors to produce an aggregate amplifier, designed for use in computers. A microphone, originally created by Emile ...

The University of Utah has made a microcircuit capable of surviving high levels of radiation. The university previously made this tiny micro-electro-mechanical system capable of cutting a single hair.

The most sensitive work environments, like nuclear power plants, demand the strictest security. Usually this is achieved by air-gapping computers from the Internet and preventing workers from ...

We are always impressed with something so simple can actually be so complex. For example, what would you think goes into an analog computer? Of course, a “real” analog computer has opamps that can do ...

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 circuit was designed to meet a medical application’s requirement to drive a laser diode with reasonable precision and a minimum of components and footprint (the device is now in clinical trials).

Now is an amazing time to be involved in the hobby electronics scene. There are robots to build, cheap microcontrollers which are easy to program, and computers themselves are able to be found for ...

Chaotic circuits can arise from either computed (using Analog Computers or Digital Computers) solutions to coupled differential equations or from unstable systems/circuits. A new open-source circuit ...
