Introduction: DIY Micro Amplifier
this is just a simple diagram of how to make a amplifier and pins
comment for more projects :P
parts:
1. lm386
2.wire
3.9-volt battery and connector
4.speaker
5.10k ohm resistor (1/4 watt)
5.220 mf cap. (10.volt)
6.3.5mm audio jack
7. an afternoon :P
tools needed:
1.soldering equipment
2.helping hands (u can do it without it just makes the job alot more easy)

Nice start :-)
Next step: using a resistor or variable resistor to adjust the gain of it. (using the gain-pin):-)
Oh, and try to change the capacitors, so you can improve the bandwidth of the amplifier :-)
