5.220 mf cap. (10.volt)

6.3.5mm audio jack

7. an afternoon :P

tools needed:

    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 :-)
