Introduction: Home-made Audio Amplifier

Picture of Home-made Audio Amplifier

Is is the very cheap audio amplifier which u can made at home..
it helps to change tone,gain,bass n clarity of songs...
u can also connect ur cellphone and get output from speakers or headphones as u wish.. :) 

Step 1: Components

Picture of Components

to make this project u wil need :
1- LM 386 semiconductor (IC)
2- 100 micro Farad capacitor
3- 220 micro Farad capacitor ( acts as bass controll)
4- 10 ohm resistor
5- 5 kilo ohm variable resistor (acts as gain controll)
6- 100 ohm variable resistor
7- 0.01u capacitor
8- 0.047u capacitor
9- Wires
10- 9V Battery clip
11- 9V Battery
12- 3.5mm stereo jack male
13- 3.5mm stereo jack female
14- Breadboard (or you can use dotted board and solder)

Step 2: Circuit Building

connect the circuit as showwn in following diagrams:

if u dont know about 3 pins of audio jack then search on google.....


Step 3: Testing & Finishing

nw test ur system by connecting ur audio device to male jack n headphones to female jack or directly to speakers....
use screw driver to change resistances which changes tones & gain, volumes of ur song & makes it more coool.........!!!!!!!!!

post comments if u know smthing more about that which makes amplifier more cheap & more cool....!!

Great job stealing someone else's instructable. You must be SO proud of yourself right now.

What rimar means is that he uses google translate to view instructables because he doesn't speak English. It would be a good idea in general to fix any grammatical errors and spelling mistakes so google translate can translate it for him. I know how much it gets on my nerves when I can't view a web page because it won't translate. Cool project!

Please use plain English or another language.
