You can trick a digital controller that uses a thermistor for temp sensing by adding a resistor in parallel. I used a 47k ohm resistor and my set temp is 20 higher than my desired. Basically set it at 57-58 and get 37-38 internal temp.
I have a wine cooler I got for free from offerup. It has thermoelectric cooling which doesn’t use a compressor. The cool thing with this type of system is it uses a solid state die that you apply 12v to one direction and it’ll cool if you reverse the polarity it’ll heat. I simply put a switch in...
