Hi all,
I've never seen a stoker or guru in person. I've rigged up a scats circuit that I found on the internets. It's basically a cruise control, set it when the pit temp is where you want it and it toggles a fan on and off to keep it there.
I dug through a box of old cpu fans and tried them each to see what sort of air volume it was capable of. I settled on a 1.5" square fan from and old pentium cpu that wasn't overly powerful and adapted it to my smoker intake. I'm confident that it wouldn't move too much air.
I got the pit up to temp, and flipped the switch. When the temp started to settle and the fan kicked on I was puzzled that the pit temp dipped from 224F to 210F then 200F. After 10 minutes or so it was still hovering around 200F. I cut off the intake so the fan stopped blowing into the smoker and the temp climbed up to 230F with all intakes shut.
Next time I'm considering to let the fire get going with the blower on and see if it reacts more as I would have expected.
Does this indicate too large of fan? Or did it just take a while for the fire to transition from naturally aspirated burning to forced air burning? Or is this how a forced air system behaves in an UDS?
I know that many here feel that an UDS works perfectly fine without gadgetry, however, I feel more comfortable leaving the cooker unattended with some sort of adaptive control in place.
Thanks,
Marlin
