Simple Electronic Stethoscope Circuit
This Simple Electronic Stethoscope Circuit teaches us about how to make one type of stethoscope circuit. Normal stethoscope uses tube to listen small sound from body like heart and lung but this electronic stethoscope uses small electric parts to make sound more clear and loud. The circuit also help doctors and nurses hear better what […]
AVC Automatic Volume Control Circuit
This AVC Automatic Volume Control Circuit work like auto volume knob, as it hears the sound coming like music or talking and then change volume by itself. Also, if the music plays at a low volume, the circuit makes it louder and if the music becomes very loud, the circuit reduces the volume slightly. Hence, […]
Infrared Wireless Headphone Circuit
Anyone can make its own wireless headphones using this Infrared Wireless Headphone Circuit, as this circuit sends sound by using infrared light but not with wire. So we can move around easily while listening and we can also control it from far like change volume or songs. What is a Infrared Headphones Receiver Circuit: The […]
35 Watt Bridge Amplifier Circuit using TDA2030 IC
This 35 Watt Bridge Amplifier Circuit using TDA2030 IC show how to make 35 watt amplifier circuit, as this circuit is also very powerful. Here, the circuit uses a special chip called TDA2030 in a different configuration to produce double the power output and make the speaker sound louder. Hence, be careful circuit uses high […]
70 Watt Audio Amplifier Circuit
70 Watt Audio Amplifier Circuit teaches us about one amplifier circuit, which makes sound louder using special parts call MOSFETs which is the type of transistor. Why this transistor is good for amplifier: Note: This circuit is little hard to make than the other projects. Circuit Working: Parts List: Components Quantity Resistors (All resistors are […]
