Constant Current Generator Circuits Explained
Constant current generators (CCGs), as the name suggests, are circuits designed to produce a steady load current regardless of significant fluctuations in load resistance or voltage levels. Basic Constant Current Generator Circuit Illustrated in Figure 1 is a basic example of such a circuit. In this configuration, Q1 operates in the common emitter mode. A […]
Piano, Guitar Sound Effect Generator Circuit
Music is a part of our lives, accompanying and enhancing our everyday experiences. While it is easy in electronics to generate a single note, for example, using a simple astable oscillator, one can only dream of the myriad of sounds available on even the most ordinary synthesizers, versatile and almost indispensable instruments today. A musical […]
Random LED Number Generator for Gambling Application
In this post I have explained a random LED number generator circuit consisting of a 4 x 5 LED matrix, numbered from 1 to 20. On pressing a push button these LEDs begin illuminating randomly, until finally a single LED corresponding to a specific number remains illuminated. Thus, this random LED number generator can be […]
Guitar Distortion Generator Preamplifier Circuit
Distortion and overdrive are types of audio signal enhancement that are employed to change the tone of amplified electric musical instruments like guitars. Typically, this is accomplished by increasing the gain of the instrument, which results in a “fuzzy,” “snarling,” or “grinding” tone. Depending on the type and degree of distortion used, the effects change […]
220 V Multiple Light Effect Generator Circuit
If you are looking for a multiple light effect generator circuit to generate sequencing, reverse/forward light effects, using 220 V colorful lamps, then this circuit might help you. How the Circuit Works The following figure displays the Light Effect Generator circuit diagram. This circuit has an oscillator, a few control logic stages, a 5 V […]
