I've tried it with a few different microwaves and it does not work well. Even with the rotating platter the microwaves still produce hot spots inside, so as the food spins, whatever parts pass through those hot spots tend to heat a lot faster. -Mario -----Original Message----- From: piclist-bounces@mit.edu [mailto:piclist-bounces@mit.edu] On Behalf Of Peter Sent: Friday, January 13, 2006 1:24 PM To: Microcontroller discussion list - Public. Subject: RE: [OT] Need help with some thermodynamics concepts (or source of it) Silly question: can you use a microwave oven ? The bugs are not affected by the microwaves afaik, but this needs to be tried. Because if you can, then you ca control the heating directly into a, and without stirring at all. And controlling a magnetron on/off or proportionally is not that hard. (proportional control actually works - try it - yes if will be off frequency but the radiation stays in the box - output power is proportional to effective anode voltage squared or raised to a higher power).
