How to make dc voltage: This is a circuit diagram for making voltage. this circuit is for dual volts. here used a full wave transformer. this transformer is ac 35-0-35 voltage. this ac voltage makes dc using 4 diodes and 2 capacitors. usually, this circuit needs an amplifier—positive- negative, and …

How to make music light for the amplifier: this is the Music light for the amplifier. we need this circuit for our amplifier. it makes the amplifier gorgeous. It’s the display only. also, it’s called the sound level. here used a transistor only. one transistor for one led. here have …

How to make stereo amplifier : This is a 2.0 amplifier circuit diagram. this is a bridge mode circuit. this circuit is based on STA540. this IC has 4 inputs and 4 outputs. but here it’s made in bridge mode. now it’s a stereo circuit. Right and Left speakers. this …

how to make a rain alarm: This is a rain alarm project. this circuit makes an alarm when it gets water on its probe. This prob works in this circuit as a switch. when the probe gets water then it works as the switch and then the alarm makes a …

How to make an amplifier: This is an amplifier using STA 540. this amplifier has 4 inputs and 4 outputs. This type of circuit is used in cars. but if we want to use it at home or other also we can use it. this circuit sound is so fine. …

How to make a home theater amplifier: How to make home theater amplifier. here used one IC. STA540 is a 4-channel amplifier IC. This IC has 4 inputs and 4 outputs. here this circuit has 3 inputs and 3 outputs. 2 for stereo and another 2 inputs make in a …

How to make level light: It’s a music-level light for an amplifier. normally we use this circuit for the amplifier. but this circuit is a different one. this circuit does not need any voltage to run. this circuit run with audio voltage. for this, we can use this circuit for …

how to make the sound booster? This is a sound booster circuit diagram. this circuit boosts the sound. It’s also like a pre-amplifier. sometimes we need to increase the sound. that time we need this circuit. we also can use this circuit for the headphone to increase the sound. some …

How to make an easy amplifier: This is an easy amplifier circuit diagram for learning people. we know the transistor makes small into big. also works as a switch. here we use one transistor to make a small sound into a big sound. this is an NPN transistor. C2073 transistor. …

How to make a small amplifier circuit: This is a small amplifier circuit diagram. it’s 10 watts. this circuit run with 12 voltage to 15 voltage. this circuit used TDA2003. this is the mono-circuit diagram. if we need stereo then we have to use a dual circuit. One circuit for …
