Things we need to make USB powered audio amplifier

TDA2822 = 1
100 u.f Capicitors = 2
1000 u.f Capicitors = 2
10 u.f Capicitors = 2
10 k and 4.7 k resistors = 2
Two small speakers from your pocket Radio or Mobile etc.

All this stuff is very cheap to buy. You can get all above in $2 only.

Now Place these components, as shown in circuit diagram
