Am I Hot or Not
Sure, it's not the dream system with computer-controlled vents on the furnace and a genetic algorithm to optimize heat-flow, but it is pretty damn cool. This system makes use of Dallas Semiconductor Digital Thermometers to monitor temperature throughout the house. Hopefully the fellow running the project will put up the source to the Linux driver he has running the sensors. This project ties in nicely with the question posed by a recent Ask Slashdot as well.
Whew... For a moment from the title I thought it might have been a competition amongst developers to determine if they were Hot or Not. I don't think a lot of the egos out there could take that kind of abuse.
