DIY Wine Chiller Incubator

DIY Incubator completed, just need to glue or tape probe wires down. Instead of drilling a hole and using heat tape inside, I decided to reverse the polarity of the cooling unit of the wine chiller itself. Hooked it up to a t-stat and ran the probe wire through the drainage hole on the chiller. It's now heating. It's staying in my desired temp range (80.8-83.2)for corn eggs, confirmed with a digital probe thermometer and temp gun. It stays on for about 90 seconds, and shuts off for about 10 minutes. It's been running for a couple days now.My questions are, has anyone else done this, and were there any problems?

Also, it seems i can't attach pics anymore?When did this change? Thanks everyone :snake:

Neat! I would love to see specs on this build. I have an old, but currently functioning coca-cola mini fridge that I want to use, but I feel kind of bad gutting it since it still works just fine.
