Coolbot replacement

Hi folks,

Ever hear of a Raspberry Pi Zero micro miniature computer?

My husband and I were just talking about building a walk in cooler and using a LG AC unit and a Coolbot as previously suggested. However, he said he can use the Raspberry Pi to do the same exact thing as a coolbot for less than $100!

Just curious if there's any interest out there for this? My husband has a small business where he builds ham radio computers (its called Omnia SDR). He also configured, built and installed our solar array. He is definitely a techy nerd.

If this would be better placed under Just Talk I'll be happy to move it....

Would love to know your thoughts!

has this proceeded, it's a very promising thread. In my case i have a passive cold cellar below grade, with dirt floor, not cool enough when the apples come to harvest, but fine during dec to June. would like to put a coolbot or equiv into service.
