Do these stokers like the Guru, Rocks, and so on use a relay to pulse the blower fan or do any have analog control?

Just curious. Question

Not sure on commercial versions but the one I use doesn't have a relay. It uses the 12VDC that powers the board for power and variates the voltage for slow to fast. This is I followed and built for my smoker. https://github.com/CapnBry/HeaterMeter/wiki/An-Introduction-to-LinkMeter---HeaterMeter

Thanks PaleAle. I would think that analog PID would be the way to go. You would get constant air flow vs pulsing the fan. I saw this controller http://www.auberins.com/index.php?main_page=product_info&cPath=14_27&products_id=351 and noticed that it has a SSR output. I was wondering if that's the way most commercial products operate. The SSR has to be less expensive though. I imagine the pulsed fan control produces temperature in a sine wave type of format. I'm not sure how tight the control is, perhaps +/- a degree or two? Maybe 5 degrees? I was wanting some feedback from somebody that has a commercial unit.

I'm thinking about rolling my own controller.

Yea I made one with a pid similar to http://www.auberins.com/index.php?main_page=product_info&cPath=1&products_id=1 and a computer blower actually this one http://www.surpluscenter.com/Electrical/Blowers-Fans/DC-Centrifugal-Blowers/23-CFM-12-VDC-BLOWER-PAIR-16-1358.axd. I have a large stick burner and it works great IMHO

Fixed the link for you...

Not a bad price for those fans. A little sheet metal work and you're home. Whenever I get motivated to do this I may hit you up for the PID settings, that is if you don't mind.
