    Pool water level stabelizer

    Thank You for your input, but I have a question. Why would you need2 transistors, why not just one? why do you need them in the first place? I understand what a transistor does, but I don't understand why I need one for this project. Please explain.

    Pool water level stabelizer

    very true about the corosion... Where would you get a mercury tilt switch or a magnetic switch? How much would either be?

    Pool water level stabelizer

    would it hurt anything if I were to just use 2 metal rods so that when the water got high enough the 12vdc flows from one electrode through the water to the other? 12vdc isn't enough to hurt anyone any way as long as it is at a low amperage, right? it would look something like this, but it would...

    Pool water level stabelizer

    A mercury tilt switch like in an old thermostat? I don't think that would work because if it is colder then it would take a higher water level to turn it on, or reverse if it is hotter. that would be good if the mercury didn't change with temperature changes.

    Pool water level stabelizer

    A 'float switch' isn't exactly what I am looking for/need. From what I can tell float switches are for turning on pumps when you have 2 feet+ of unwanted water. I need a switch that turns on/off with 4-6 inch precision.

    Pool water level stabelizer

    below I have attached a diagram of my idea. When it rains my father's pool starts overflowing with water so he has to go out and hook up the sump pump and let it run for a while. Sometimes he forgets that it is running and he pumps too much water out. So my idea was to make a switch to turn the...

    IR gate counter HELP!

    So I'm a little confused, here is how I think it should look... I'm confused about where to connect pin 5, I am assuming that it connects to +5v, I don't know... Take a look and tell me what you think...
