In this post I have explained how to build a simple crystal tester circuit using ordinary parts like transistors, resistors, diodes and capacitors. What is a Crystal A crystal can be used for making an electronic oscillator circuit by using the mechanical resonance of a piezoelectric vibrating crystal to generate an electrical frequency having a […]

Understanding Crystal Oscillator Circuits
Crystal oscillators are electronics devices that produce stable, accurate, and repeated signals that are widely employed in a wide range of electronic applications. Because of their great stability, precision, and low noise, they have become a crucial component in many electronic circuits. In this post, we will look at how crystal oscillators function, as well […]
Make this Crystal Radio Set Circuit using No Batteries
A crystal radio circuit is probably the simplest form of radio that uses hardly any electronic components, and needs absolutely no external power for the operations. Crystal Radio Concept The only downside of this radio concept is the requirement of a very long antenna and a deep earthing, therefore this unit is not something which […]
Crystal Radio Sets with Amplifier Circuit
A crystal radio receiver, often known as a crystal set, is a simplest form of radio receiver that was widely used in the initial periods of radio. A crystal radio set does not require any external power supply to operate. Instead, it simply makes sound using the energy of the radio signals that is received. […]
