Here we are going to see how we can build a very simple, yet perfect FM radio circuit using one single IC called TDA7000. This IC already has everything inside it, so we do not need to do too much headache wiring around it. First of all, before we build, we must understand what each […]

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 […]
3.7 V Class D Speaker Amplifier Circuit for Differential Analog Input
A class D amplifier is basically a category of amplifier in which the power devices (mosfets and BJTs) are operated like switches. The associated output devices in such amplifier circuits either turn fully ON or fully OFF, but never switch between other undefined levels ensuring minimal heat dissipation and maximum efficiency from the devices. […]
How to Make Active Loudspeaker Circuit
In this post I have explained to make an active loudspeaker system circuit for enabling self sustained amplification of any music source that may be directly plugged in to the active speaker box. Introduction With the advent of ultra modern cell phones, now it has become possible to store huge music data and listen to […]
Simple Bird Sound Generator Circuit
The diagram presented below shows a simple circuit of a bird chirping sound generator. All the parts are very common and the transformer is an ordinary type as found in small transistor radios at the output stage Circuit Operation The circuit is basically a feedback oscillator circuit that is configured around a small output transformer. The transistor forms the […]
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 […]
