All right, here we go ! Pictures !

This is my styrofoam box, with a heat cable attached to the bottom.



This is when I have added some water bottles on top of the heat cable. Note that I will add two more bottles.



Next up is with bars on top of the water bottles.



And at last, a box with no eggs in. I will not use that box as my egg box.



And then of course, a termostat and a termometer (which isn't in any of the pictures).

What do you think? ;d
