I submitted MisterHouse to Hack A Day a while back, and they have recently featured it. See the entry here:
For those of you who are unfamiliar with Hack A Day, they do a daily blog listing of D-I-Y projects, modifications, and hacks (mostly in the original non-nefarious sense of the word). Be sure to check out their archives, there is some interesting stuff in there! From odd things like making a digital clock out of an oscilloscope and lava lamp random number generator, to a homebrew Segway, wind turbine, aluminum foundry, and tig welder.
There even an article on hacking the GM Onstar system to use the built-in GPS with your laptop. Perfect for the Mister House GPS Tracking module!
