In this post we talk about a couple electronic drum sound simulator circuits which can be used for replicating actual drum beat sound electronically, using a few op amps and few other passive electronic components. Using Capacitor as the Sensor Instead of Piezo Conventional electronic drum kits incorporate the use of piezo disc affixed to […]

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. […]
Build this Open Baffle Hi-Fi Loudspeaker System with Crossover Network
The open baffle hi-fi, high quality speaker design introduced here provides a substitute to the common loudspeaker housing. Its sound emission pattern resembles electrostatic pattern. It works without enclosure or housing for the woofers, although employs normal dynamics for the drive units. The reproduction provides extremely ‘spacious’ impact on the ears.

Audio Delay Line Circuit – For Echo, Reverb Effects
An audio delay line is a technique in which a given audio signal is passed through a series of digital storage stages, until the final audio output is delayed by a certain period (usually in milliseconds). When this delayed audio output is fed back to the original audio, it results in an amazingly enhanced audio, […]
Echo Effect Generator Circuit
In this post I have explained a circuit which can be used for transforming an ordinary music into a music with depth and echo effects. Generating an echo effect electronically involves a process in which an input signal is extended and then mixed with the original signal to create collapsing decaying effect, which ultimately results […]
