The difficulties that I see in applying this to coffee roasting are temperature (up to ~420?F) and the metal dog bowl interfering with the magnetic field. A glass dish could be used, I suppose, but it's resistance to heat could cause problems. There is also the drill option: http://www.homeroaster.com/Loroast.html Not sure how well it would work with the heat gun... Here are a few ideas that you might also find useful in your brewing:

I will have to do some more research. The guage holders are pretty cool, and very useful. We used them at MACI, and I was happy to find one in the garage, left by B's tool & die making grandfather. The coffee really is good... I heard about a yeast stirrer that sounds like it might work. I will have to do some more research. The guage holders are pretty cool, and very useful.

I am sick of stirring too. But the coffe tastes as good as ever... Hey, when you perfect your coffee roasting robot, can you clone him and send me one? I am sick of stirring too.
