Temp Logging / Web Reporting / Alerting
I just set this up for piece of mind while on vacations, at work, etc. Along with this logging, alarming and the facility to shut my halides off from the web, I'm more comfortable that my non-AC'ed house wont fry my tank while I'm gone
All in all this cost under 40 bucks and two hours ( if you have a webserver lying around )

Here are the parts and software I used to get this set up.
USB to 1-wire adapter:

1-Wire Parasite Digital Temp Sensor:
This item is on engineering hold from Maxim. From what I understand there is some type of bug when you're using multiple sensors. I dont think they are due to be restocked until December.
I ended up ordering the old model ( which seems to work fine for this application ) from a canadian company that had them in stock:
