This thought just came to me last night but I wanted to get the collective Homebrew Talk wisdom on it first...
I have always wanted to have better control over my set points during fermentation, but also I'm also a bit too lazy to keep checking on activity throughout fermentation - the (potential) game changer... we can work out roughly how much heat energy should be released during fermentation (calculated from the amount of sugar and how much heat yeast produce per frame of sugar converted to alcohol and CO2) and we can measure how much heat a freezer/fridge is removing from the space from how much it is on (and a bit more maths, plus factoring in any losses to the general atmosphere), so by comparing how much energy has been remove by the fridge with the total expected to be remove we could estimate roughly how far through fermentation we are at... I think
So the question - do you guys see any big hurdles I haven't seen or assumption that don't make sense? Just so I don't waste a whole lot of time... but I do have 3 more weeks at least to fill so I will probably dig out some of my old Arduino gear to see what I have and how far I can take it...
