Due to some reason if the loudspeaker of a power amplifier gets shorted, that may lead to a fatal damage to the amplifier component. To prevent this an amplifier short circuit protector circuit can be very useful. In the following post I have explained 2 simple amplifier short circuit or overload protection circuits for safeguarding […]

DIY 100 Watt MOSFET Amplifier Circuit with PCB
MOSFET based amplifiers as we all know are outstanding with their sound qualities and they can easily beat the performance of other counterparts based on power transistors or linear ICs. Why use MOSFETs in Amplifiers Amplifiers based on mosfets are not always easy to design or make. Moreover after assembling a prototype, testing to perfection […]
How to Make a Telephone Amplifier Circuit
The simple telephone ring tone amplifier circuit I have explained in this article saves the inconvenience of picking the telephone handset while speaking over a call. This circuit also particularly becomes useful when there’s a need of the conversation to become audible to a number of people or a group of people. Introduction When the […]
Simplest Piezo Driver Circuit Explained
In the previous post I explained a piezo transducer element and learned how to use it with electronic circuits. In this article we will see how a piezo tranducer can be driven or operated using a simple circuit. As discussed earlier a piezo transducer basically requires a frequency to vibrate and reproduce the required sound. […]
Make This Powerful 200+200 watts Car Stereo Amplifier Circuit
No complex wiring, no costly MOSFETS and no cumbersome heatsinks, yet a powerful 200+200 watt stereo amplifier circuit, which can be built within hours using just a couple ICs, right in your home. Yes we are discussing the state-of-the-art thick film hybrid IC STK4050II, by SANYO.The IC is specifically designed for amplifying music at an […]
Simple FM Radio Circuit Using a Single Transistor
When it comes to making an FM receiver it’s always thought to be a complex design, however the one transistor simple FM receiver circuit explained here simply shows that it isn’t the case after all. Here a single transistor acts as a receiver, demodulator, amplifier to constitute a wonderful tiny FM radio. It’s basically based […]
