Alright time to test! I need to make sure the fridge works well or using the parts for the robot are pointless. First thing I noticed from visual inspection is there is no external radiator... Hmm maybe it's inside? Maybe it's small enough it doesn't need one. Anyways I'm running it for 20 minutes and one hour marks to measure temperature. 

Before applying power to the compressor

At 20 minute check in, the realistic time people want to have their beverages! We are down to 41 degrees.

1 hour mark, Boom! Super cold beer!  26 degrees. Of course, I will adjust the thermostat but it is analog so there is no markings for what temp it shuts the compressor off. I will likely stop it at 36 degrees.
