Is it possible to power a device that takes two AA batteries using the power from a USB port? Answered
I have a small fountain that takes two AA batteries. It looks great sitting on my desk but I'd love to have it powered off of my USB rather than go through AA's all the time. Is it possible to use the power from a USB port to power the device, and if so, what would need to be built (as far as circuitry to protect the usb ports and get the correct current, etc) to do this?
