I love all about electronics, circuit diagrams and crazy projects that can help us achieve almost everything our mind can conceive. I created this website and I want to invite you to participate in ...

In this final installment, we look at 555 timers, voltage regulators, op amps, audio power amps, peripheral drivers, and interfaces for circuit protection ... bipolar ON/OFF signals from the SQWG ...

The circuit of Figure 1 generates sinusoids ... This very-low-frequency sine- and square-wave generator requires few components, but provides low-distortion outputs (derived from LTspice simulator).

The simplified block circuit shows IC1 operating as a square-wave generator with frequency determined ... 1. The block diagram shows how three low-power audio amplifiers (LM386) are configured ...
