Re: gEDA-user: random project idea

[Steve Meier <smeier@xxxxxxxxxxxxxxxxxxx>]

An interesting hobbyist project might be to modify a hot plate to be
computer controlled with a thermal couple feed back loop to meet
Altera's requirements.

Max temperature needed is 260 C

A quick look shows that Target is selling a hotplate that does 806
degrees F (I presume)
