Simple LM386 Audio Amplifier Circuit
This post shows you how to build a mini amplifier circuit using a common chip called the LM386. It is cheap, easy to make and can make your music player or speakers much louder. This amplifier is perfect for small projects and is not powerful enough for huge concerts, but it is a great way […]
Simple Small Amplifier Circuit Using Transistors
The simple small amplifier circuit using transistors functions, as a basic audio amplifier designed to amplify weak signals and enhance the audio experience particularly in car radios. Let us find out into the operational details of this circuit: Circuit Working: Parts List: Category Component Quantity Resistors 100k 1/4W CFR 1 1k 1/4W CFR 1 Capacitors […]
Simple MIC Preamplifier Circuit using an Op-Amp
This article shows you how to build a microphone amplifier circuit using a chip called the IC LM358. Regular microphones have very weak signals, and this amplifier makes them much stronger. This circuit is better than simpler designs because it uses a special chip called an operational amplifier op amp. This makes the signal stronger […]
Simple IC 555 Amplifier Circuit
The IC 555 chip is quite helpful in a lot of electronic circuits. This project differs slightly from the usual usage in timing circuits. We will build a microphone amplifier in this project using the IC 555. Initially, your voice is captured by a microphone. It then gets a modest boost via a transistor which […]
1 Watt Hi-Fi Amplifier Circuit
Big bulky speakers are a thing of the past for sound systems. Today most systems use a special part called a complementary output stage to make them smaller and work better. This article will take a look inside a small 1 watt amp and show you how it works step by step. What is a […]
