Introduction The electronic bongo circuit creates a bongo drum sound when you touch the two sensor plates present on it. You can make the touch plate sensor using any conducting material like copper or aluminum. In this article I would…
The circuit consist of least numbers of electronic components, The transistor is act as a switch here. The transistor is open and close to control the Light. The exact functions of the circuit is explained here, Share Button Share on…
When the electronics project is builded for dual power supply voltage, But you have only a single power supply source like Battery or a DC adapter. The single power supply can be converted into a dual power supply. To do…
Protect your amplifier by overload, through maximum output it takes out from the amplifier. This will damage the amplifier system and speakers. Kids may blow up the amplifier when the parents are not at home, in this situation you can…
“Clipping indicator is a type of useful signal indication when the maximum limit is reached by the amplifier. The maximum level of sound output is reached that time the speaker may get damaged and also the sound also distorted. To…
The amplifier circuit has two main functions, it can work as a small and powerful amplifier. The power rating of 8 watts at 8 ohms impedance. The second one is that the IC can provide 2 to 22v supply and…
The Phono Preamp has a precise RIAA equalization curve and is very quiet and the best audio amplifier circuit you will ever get. Most of the people are building this secret circuit and do sales in the local market. Performance…
