Has anyone ever made a Temperature display for their pc or has anyone got any info on how to make one?
It would be a pointless exercise IMO, as there are plenty of cheap ready made diplays on the market. http://www.directron.com/fp706sl.html Failing that, just use one of the many software displays available.
buy a cheap one and reverse engineer it then you know how it works put it back together in your own case and hand it in
