Hi, i have been using my homemade incubator for a year, but now i want to build a new automatic one that controlls the tempreture , humidity, and turning eggs. i'm thinking to use an old fridger , and to install all the things on it, for the tempreture i think a heat element like this one but bigger than this to fit on the back of the fridger , and a similar one to be on the water (for controlling the humidity). the water will be on the bottom of the fridger. i will install a big fan on the back of the fridge , all of this parts will be controlled and activated by this unit : http://www.aliexpress.com/item/Egg-Incubator-Tempreture-Controller-HTC-1-for-sale/611098273.html or something similar. what do you think ? this gonna work ? does anyone used this controller ? thanks.
