I threw a bunch of cool videos of making a bator. into my incubator page.Your welcome, you should still talk to sallysunshine and marinecorpfarmer (sorry if spelled there names wrong) they may not have built the exact type of bator you want but they will have alot of info on the wireing and other things that run similar no matter what type of bator you build. Good luck and have fun .
You could get alot out of watching them and understanding why you are doing certain things! and understanding ambiant heat vs radiant etc.... https://www.backyardchickens.com/a/incubator-incubator please keep us updated! would love to watch as you make it!! COOL!!
