DIY HVAC
An anonymous reader writes "I found this very interesting project called DIY Zoning. It allows one to add air flow balancing, temperature control, zoning, home automation, and more to an existing or new HVAC system. After getting a $200 electric bill, this sounds like a good solution for those who are getting screwed with outrageously high electric bills due to their HVAC unit especially since organizations like TVA have raised the electric rates."
WTF is an HVAC???

go to home depot, buy a $30 digital thermostat. install it yourself (its 3 wires for the heat/AC and a AA battery for the thermostat). program it so in the summer your AC is at 78 when you are home, 85 when you are at work, and in the winter, 68 when you are asleep and 72 when you are home). the digital thermostat will easily pay for itself in 1 month in the summer.
