DC Motor Air Pump
I need a air pump for my aquarium and I have tons of DC motors, I was thinking of buying one, but they are so noisy and its so much cooler to use old parts to build something. I found some projects here for water pumps using DC motors, but what I want is to build a system, using a DC motor that brings air from the outside through a small hose into my recipient, in this case my aquarium.
Have you guys/gals ever heard of something like that? is it possible?
