Sorry I just need to rant and rave for a bit. I called the local hardware store. When the man answered I asked him, what is the cheapest thermostat that you have in stock? I said it doesn't matter if it is a hot water heater thermostat or a household heating/cooling thermostat. So he tells me to hang on a minute, in the background I hear him talking to another man saying this lady wants to know what our cheapest thermostat is. Then something is said a little quieter and they both laugh. The other man then picks up the phone and asks if he can help me. So I repeat I need to know what the cheapest thermostat you have in stock is. He said well what is it for? So I say I plan on building an incubator. I don't care if it is a household thermostat or a hot water heater thermostat. So he says to me hot water heaters don't have thermostats..............Seriously? So I say oh really then how do you regulate the temperature in one. So then he says you wouldn't be able to use one of those anyway. So I say yes I will I have the wiring diagram. So then he says well we don't stock them. Ok do you stock heater thermostats? Yes but what temperature do you need? 100 f well that won't work for you they only go up to 90f well we will find a diagram to adjust it to work as I have seen others that have used one. NO it won't work for you. You should just go and buy an incubator. The whole &^*^&*()& conversation with a condescending attitude towards me. I hate men that think all women are dumb. I have already built one homemade incubator that works very well and would like to finish my mini fridge bator so that I can do staggered hatches with a better hatch rate but now I will have to drive 30 minutes instead of 7 and wait 3 days until I can use the car instead of the truck. Sorry just needed to let off some steam, tried to complain to my fiance and he laughed. He said I will never change peoples views of me. I sound like a child on the phone and I am a small blond so I just have way to many strikes against me.
