Well, out of shear stupidity, I'm going to pursue a project to do soon. What I have in mind is to make, a portable sound system. Hopefully, I can make it solar powered, although, I don't know where I can get my hands on a solar panel. Anyone have any clue where to go?

Remember, the internet is your friend. Though, if I remember correctly, solar panels aren't too cheap.

The main problem you'll encounter is the need for using ultra sensitive speaker drivers (eg: wattage efficient), which will likely mean little to no bass. These would be drivers of the type many cheap PC speakers are using where they employ little cupped aluminum tweeters. However, the poricing on miniature panels is not too bad anymore. Here's a place that specializes in mini panels. [COLOR=blue]http://www.solar-world.com/SolarMini-Panels&Motors.htm[/COLOR]

Aren't there small amplifier blocks that I can use?

Don't know whether you mean inverter or speaker amp, but adding a speaker amp to the mix, esp if it's enough to power mid-range or bass speakers is going to considerably up the price of the solar panels used. However it does depend on whether you just want the panel to charge batteries the speakers contain or actually power them. Just to get a clear idea of what I'm talking about, I'll elaborate on what I found regarding solar laptop chargers. They run anywhere from $190 to $1000, the lower price in that range does not guarantee you can actually run one off it with no mention of the wattage output. Some models in the $290 to $385 range come with bulky power inverters, which gives you an idea of what it takes to run a laptop on just a solar panel by itself. The better laptop charges like those made by CT Solar cost several hundred dollars and tell you exactly how to calculate the wattage output you'll need for your laptop, which is 32W on average. Then there's the circuitry they come with to regulate the output, which isn't cheap either if it's made right. To take on a project like this it is best to already have a fair background in electronics and a firm understanding of what it will involve. It's not as simple as one might think. It's a lot like the DIY LED lighting systems people make for cycling and such. That is a very complex thing too involving LED conrollers and calculations. Such lighting systems were slow to emerge onto the market due to price, light output, heat, and controller issues. My advice, stick in the 3-6v low amperage range with small, limited range, high efficiency speakers, otherwise this project is going to cost more than it's worth. Unless of course you or someone you know really knows a lot about this and you can get sponsor funding for it.

BAHAH!! I'll just power it by batteries then. I was hoping I could do something where I could take the thing, put it on the beach, and listen to music for hours without having to worry about batteries running dead and I'd be an environmental person....lol. But anyway, thanks for the help. I was hoping I wouldn't have to break the bank on this, so I guess a solar panel is out of the question. Well, I guess an old radio, with its speakers removed and the main part all broken down into pieces that I could place where it would fit, would do. I dunno. Lol. Just another one of my ideas.

There are lots of very low watt speakers, but on the beach they're not going to sound too good. You'd be better off with a good pair of headphones that are open back so you can still hear others, but obviously it's not the social way to go if you catch my drift.

Ahhh, I see. Maybe a cheap boombox would work.

What about a normal battery system with solar charged batteries? Maplin > 4-Battery Solar Charger Or a solar charger for your player? Solar Technology

Hmm....good idea. Looks interesting.
