How can I make/modify/find a small water pump that runs off battery power? Answered
I'm looking to see if it's possible to either build, modify, or purchase a pump to circulate a small (<1 quart) amount of water up/down a slight incline. It needs to run on a battery, preferably a standard household battery (AA/A/C/D). In addition, I'm on a tight budget for this project, so it needs to be as cheap a solution as possible.
