Here is the shortest cook log I ever made. notice a very short "stall" over 180 degrees. 10 lb brisket in an electric Butterball oil-less infrared cooker. https://drive.google.com/file/d/0B6czbofWF3TxZlNBTWpkazBFQ2M/view?usp=sharing Ambient temp is reported as the pit temp. Took less than 4...

Happy New Year everyone..... I cooked a 10 lb brisket in a b_ball electric cooker this afternoon (mostly infrared heat)... https://drive.google.com/file/d/0B6czbofWF3TxZlNBTWpkazBFQ2M/view?usp=sharing Ambient temp is reported as the Pit temp. Electric heat only, fan not used. Cook took...

One of my Thermo works probes is reading about 20 degrees higher after about 3 cooks. Do you think I may have caused this by exposure to a rack ? I notice the probes I ordered during the recent half price sale have a yellow warning tag that has the pictorial icons to sasay avoid contact with...

The combustion fan on a pellet muncher should be 100% all the time (except when lighting?). The auger could have a variable duration "on" cycle or be pulsed to turn slowly, like 1-2 RPM (not exactly sure of the specs, but you could time it and see). I would suggest the use of a repeat cycle...

OK, will try it again in the next couple of weeks. Thanks for doing the backwards number test.... Was your roto assembly binding with that arrangement ? My butterfly arrangement will tip 90 degrees in each direction, so I have it setup where "closed" is the centered position i n the full...

Thanks Ralph. I found the PID explanation by Bryan at http://tvwbb.com/showthread.php?42779-Post-your-HeaterMeter-graphs&p=466141&viewfull=1#post466141 and worked through the numbers using my cook data. My cabinet is an offset with the fire outside the cook chamber so that gives a slower...

Hi, I use the HM on my cabinet smoker (door instead of a lid) and during a cook, I send the lid open signal to cut the fan for a couple of minutes while I add meat / wrap, move around or take out meat. Sometimes a door opening event is less than a minute, and other times it may be more, longer...

oto of the servo damper and wiring harness on the cabinet. Here is the servo motor and damper assembly. 1) open 2) closed. This butterfly damper is made using a piece of 5/16 hard line. I used a cutoff wheel to put 3 slots in the hard line, one for each butterfly valve centered over each...

Hi John, Any results with the lower offset voltage ? My TC setup seems to be pretty close to my Thermoworks probes... probably within the same 10 degrees you mention. I will have to look for a graph showing an ambient temp comparison. I have a couple of issues using the Adafruit board in my...

Happy Thanksgiving. I got done early this year... Turkey and Brisket cooked really quick on bottom rack. My 4th cook using the HM, and first cook with servo on the stacks in the insulated cabinet smoker. About 50 lbs total. 12 lb and 10 lb Turkeys, 12 lb brisket, 8 lb Pork Butt, 8 lb Pork...

Happy Thanksgiving... done early this year ! <edit> Oops, wrong place... see graphs section

I read this a while ago and could hardly wait to use a datalogging thermometer to "see" the stall happening. It is interesting how there is no stall when cooking at higher temps or cooking smaller meats. Also interesting is the types of heat in the smoker... convection, conduction and radiant...

Ho Ron, I like your basket shown in photo 2... is that home made or a stock part ? I am a noob on the Weber parts....

Mike, I like the idea of having some metal in between the fan box and the smoker... gives some opportunity for the operating temp to be lower for the fan. Is that piece of metal on the bottom some kind of flapper door for the air inlet ? Also, I was trying to figure out how the square output of...

Agreed ! I like your selection of parts and seeing the damper and servo as part of the design. That fan should make all the heat you will ever need ! Keep an eye on it though.... I have had fans die from the radiant heat soak when the fan is not blowing air for long periods of time. I had to...

Hi Davey, I have a similar setup and had some shaggy looking thermocouple readings as well. I had some issues with one end of my thermocouple connection where the fiberglass insulation was kind of flaky and I think one of my TC leads was getting on the shield or shorting to the other. To keep...

Thanks Bryan, I used the "invert output" to do my initial testing. When powered on with just a pit probe and the fan going at 100% (because this is all on a table, NOT on the smoker) I just selected invert and saved the configuration and the servo jumped for me. I watched it close and unchecked...

Butterfly damper mechanical layout questions... 1) Does the servo automatically go to 100% open or closed when power is applied to the HM ? 2) I want the arm on the butterfly shaft to be on the right side to make the right side of the blades go in the downward direction. In the case where...

Thinking about using phone jacks for the individual fan and damper connectors since I have a crimper tool. They should be pretty easy to protect from the weather when not in use.

Good stuff Ron. Thanks for those links. I forgot there were several integrated blower/dampers out there. I will have both parts, just in different locations. Looks like the ground is jumped on the RJ45 side on the wiki. The color code info and graphic there is really helpful too. Working...
