I know that. I'm using an old and big fridge from Privileg (Duo Cold). I thought of 'tuning' it with a microcontroller, but deemed it unnecesary after logging temperature and power use at different settings for a few days. Only impractical thing is the needed deicing after about half a year. But then I can at least clean and disinfect it thouroughly.

Which I btw. got for free from the streetside, it was just standing there with other stuff, probably houshold clearing. Saw it on my way home, checked it out, was clean. Looked OK. Went home, got my foldable sack barrow and a few rubber straps from my bicycle, went back there and had a nice upgrade to my even older, but much smaller and louder fridge. Which I then rolled to the communal recycling center a block away :)

STRIKE!
