I thought about trying a home-made pump before I caved and bought the whole NB system. It's essentially just three parts: cup, tube, pump. I gave up because I couldn't figure out what to use as the actual cups around the breasts. Maybe deep, sturdy bowls with a comfortable rim and you can drill a hole into? Tubing can be found easily at a home improvement store. If you don't have anything that can be used as a pump, you can just suck the air out.
