Simple LM386 Audio Amplifier Circuit
To begin with, in this Simple LM386 Audio Amplifier Circuit we use one popular chip called LM386 to make small sound amplifier circuit, hence it does not cost much and is easy to make and can make speaker or music player sound louder. Also, it is not very powerful for big show but good for […]
Small Amplifier Circuit using Transistors
This is one Small Amplifier Circuit using Transistors which work like basic audio amplifier and it makes weak sound signal more strong so sound come better like in car radios. So, now lets see how this circuit is build and how it work. Circuit Working: Parts List: Components Values Quantity Resistors 100k, 1k 1/4W CFR […]
Simple MIC Preamplifier Circuit
This is small and simple MIC preamplifier circuit using op-amp IC LM358 and it uses op-amp to make weak sound from MIC more strong, so it boosts low audio signal into stronger one. Also, the circuit is good to record voice or connect to speaker and it is easy to make with not many parts. […]
IC 555 Amplifier Circuit
The IC 555 chip is very useful in many electronic works, but this project is not same like normal timing circuits. Here, we are making IC 555 Amplifier Circuit which uses microphone. At first, microphone take the sound and then one small transistor give little power to sound like small switch. At last, IC 555 […]
1 Watt Hi-Fi Amplifier Circuit
This is small 1 watt Hi-Fi amplifier circuit which gives 1 watt sound power, so it is good for small speaker or DIY audio project. Sound quality is clear and nice and even if power is low, but circuit still work good. Also, this type of circuit is easy to build because it uses simple […]
