cool, a friend was just telling me about this on friday and I thought it sounded pretty interesting. I know nothing about electrical stuff, does anybody know if it would be possible to wire this up with multiple batteries to get a longer run time? I guess it wouldn't be that hard to switch out a battery but I still think having 2 or 3 batteries plugged in would be nice for bringing to a festival or something.
Just run it with a "Walmart" type battery. Either 7.2V or 9V will work.
Note: you should add a heatsink on that 7805 regulator if there is any significant current!
