I got to thinking about this when my dad came home today w/ an AC for my room. He got it at a garage sale for $15 (works like a charm). Anyways, I was thinking what if I could find a cheap mini-fridge @ a garage sale and scrap if for parts for a freon cooler. However, I have been unable to find any detailed info on how someone would go about building one of these. I know little about freon cooling besides that it is evaporative cooling and requires a compressor and some other "stuff" that would be in the fridge. Any info greatly appreciated.
