I have planed and started to build a humidifier for the incubator I made yesterday. Have already cut the metal from 26 ga. sheet meatel. Now all I have to do is solder it's seams. Testing will be performed this weekend. Filling will be accomplished through a vinel hose running to the outside of the incubator so it won't have to be opened to fill the pan. Here's a very rough drawing of the humidifier.
