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 […]
FM Radio Circuit
FM Radio Circuit is an electric brain for the machine and it is also a small electric system which catches FM radio waves and changes to sound we can hear. This circuit also uses components such as an antenna, microphone, speaker and connecting wires, which are commonly used in many radios to receive music or […]
Voice Recorder and Playback Circuit
Does anyone get tired of buying expensive voice recorders? then this Voice Recorder and Playback Circuit show how to make easy one at home! Also, we can use it to record small message for family or friend, by just pressing two button one for record and other one to listen. Note: This project is little […]
Very Low Frequency (VLF) Converter Circuit
To begin with , this Very Low Frequency (VLF) Converter Circuit talks about one circuit, which can catch very low radio waves VLF from air and make them into sound for hearing. Also, normal radios do not get these VLF waves but they only work with higher waves; and hence, this circuit is different it […]
