as some of you may know, we had a big snow storm here in rhode island - where i live we always lose power.. so i would like to builder a charger that i can plug in our cellphones and laptops into. any ideas how to go about this?
basically taking juice from regular batteries..

thanks

Well if you have the money, you can get a super capacitor and some high voltage/current regulators. The super capacitors are dangerous to use so wear rubber gloves when handling them, and make sure the wires are isolated until needed.

You don't need an Arduino for this - here's a project that might interest you: http://www.ladyada.net/make/mintyboost/. How about building a solar powered one?

very interesting.. thinking a much bigger scale.. 3 or more cell phones at a time...


pretty much everything i will make - will end up stand alones.. so i'll never need the arduino in the end
