Not my demo, but I found it pretty easy, cheap, and interesting. I'm no electronics guru, but this seems like a good solution for somebody that wants to save a few bucks and needs an ATO. All together, with the extension cord, pump, and water jug i have laying around, the only cost i've incurred is the $6.00 w/ free shipping for the float switch on ebay (which is in the mail). I may drop a couple more dollars on some acrylic to construct a housing for it, possibly with a screen to protect the float from anything that may cause it to stick... any thoughts?
