The IC TDA1554 based Amplifier circuit discussed in this article can provide up to 22 watts per channel into a couple of four-ohm loudspeakers. The main attraction is that you can construct it for less than $15. This implies that you may make a power amplifier for your car’s front speakers, another for the back […]

Electronic Drum Sound Simulator Circuits
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, […]
