I picked up a Vector Thermoelectric Mini Fridge Deluxe Cooler & Warmer, 16 liter size, and wondered if anyone here has used one to incubate dragon eggs, or keep silkworms?
I built one out of an old chest freezer. I made shelves and put water in the bottom with a submergable aquarium heater. I glued shims to the lid to allow for ventilation. You could build something similar to this with a mini fridge.
