Solar powered audio amplifier
For these summer days out on the beach or even on a barbecue, you sure need good music. For music you usually need some power and power source is not easy to find on a beach. Either way, the Sun is up there so why not harvest some of it's massive energy to power a small audio amplifier and even mp3 player.
This project incorporates solar panels with DIY audio amplifier based on LM386 chip. The interesting part is that this device doesn't require any batteries, not even rechargeable ones. Instead it accumulates power into electrolytic capacitors for use, especially with those basses.
