This project was started to entry the 2020 Hackaday prize contest.

Strangely enough they ask for heating but I always thought cooling is harder and sometimes can be more useful.

Even living in a rather cold place, summers are hot and food perishes quickly unless stored in a fridge.

While the cooling box I propose may not be as good as a real fridge it should help keep food safe longer or make the home interior more bearable.
