1-wire thermostat control

For some reason, computer controllable thermostats are pretty freakin’ expensive. I found a reference to a 1-wire thermostat in this(mirror) sample senior project on home automation. It turns out that Dallas Semiconductor put one together a while back as an application for their TINI platform. (web-application server on a chip). The write-up has since vanished from their site, but I found it thatnks to archive.org. The thermostat used to run about $50, and a similar model still seems to be produced. The 1-wire interface is pretty simple – Maxim’s TINI board to control it: not so much. Just using the 1-wire interface with an inexpensive thermostat and controlling from a PC seems pretty viable to me. Just in case, I mirrored the 1-wire interface schematics here.
Great… I love the web archive wayback machine. It is so helpfull for finding old stuff.. you might want to know that othe pages (such as the cell phone jammer) are also on there (death to the 404 :) )
