I'm a student headed for college next year and am looking for a cool summer project to do so I can make something neat and learn a little along the way, my budget is around $80 plus the stuff I already have. I am interested in renewable energy and speakers, so I was thinking about a solar powered relatively portable speaker. I have the speakers I need already (quite a few sitting around, I will likely use 2 two way Boston acoustics computer speakers). I will make the enclosure as well or possibly modify the box of an old center channel that I have that seems quite good. I am getting the solar cells on ebay for $20 or less (getting quite a few for future projects), this amp seems to have good reviews: http://www.amazon.com/DROK-TDA7297-...59&sr=8-2-spons&keywords=mini+amplifier&psc=1
and seems to have plenty of power for my application. What I really need help with is the batteries and charging systems which I just don't have much knowledge on. What battery specifications should I use (mah/votage)? How can I charge them from the solar panels given that their output will vary a lot? I should also add what I expect from the unit. I'm looking for something to play music that is relatively small for a dorm room. I can put up to 9 solar panels on the unit which generate up to 1.8 watts each and .5 volts. (So, 16.2 watts, 4.5 volts). I realize the portability of the unit is a big question, but I am mostly doing this for fun and somewhat for functionality. Any help or suggestions are appreciated. Also, if you need clarification of anything please ask.
Thank you!
