I am looking to build a low power (battery powered, with recharge eventually through wind or solar) automatic plant watering system of size suitable for my girlfriend's balcony (basically a couple tubs of tomatoes, basil, and flowers). I plan to use the two-nail system to hook up moisture detection so i can make this all as automatic as possible.
That being said, I am having alot of trouble finding a low cost/low power dc water pump. I have seen all sorts of ideas, from windshield washer pumps (too much current), to aquarium air pumps (mostly AC), to the sensidyne micro air pump AA (can't find a supplier). GPH is not so critical, and i only have to pump a trickle about 2ft up. I once bought a super cheap science project mabuchi motor powered pump from edmund scientific that i was hoping to find, but that seems to have vanished from the net (google).
Any ideas?
