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 ...

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 ...

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 ...

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 ...

In a balanced op-amp circuit, the op-amp inputs see equal impedances looking into the circuit. Balanced circuits provide better performance by cancelling some input errors and have a simple R F /R I ...
