[Novalug] Cheap (homebrew) room temperature probe?

[Brandon Saxe]

There was a homebrew article for this in a Linux
Journal of past. I can't remember which issue, though.
You may be able to find that article. The author
interfaced with a device using perl and posted results
to a website if I remember correctly.
