Intro: 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
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.....
(NOTE: U HAVEN'T CONNECT THE GROUND PIN (LONGEST PIN IN JACK) IN CIRCUIT.. )
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....!!

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!
