I've been looking into things, and might make this my next project. I would get a sprinkler system timer ($20) that would send a 24 volt signal for one or more minutes (depending on dose) to up to 4 pumps (with the model I picked). I would use a transformer to convert the 24v to 110v to drive the Peristaltic Pump listed above (I think, don't know to much about electronics)? I think the sprinkler controller uses standard plugs on the 24 volt side (I've never touched a sprinkler controller)? Total system would cost under $100 (depending on number of pumps). Compared to what these guys are doing,
