I'm sure that some of you in addition to machining metal also do some metal casting. I've done a significant amount of aluminum casting over the last year using a homemade furnace. I found that I also needed a controller to accurately regulate the temperature. I checked into buying a controller but found the cost prohibative, and the accuracy of the temp control poor. Instead of buying, I decided to design and build my own. I've had great success with this controller, so I posted the plans on a web site for others who may have an interest in building one to see what I've done.

Enjoy!

That is pretty neat. Thanks for taking the time to do the write up.
