Where do you have top damper when doing cooks manually? I'd suggest starting around that point or maybe a bit more open. Your graph suggests the RD3 was trying extremely hard to shove air into the grill and the top was blocking the effort. You will find as you open the top damper the RD3 will...

Previous 13 HM.hex with continuous operation was really starting to bug me with the roto damper sitting on my desk twitching. Actually found I could vary the twitch depending if I was using 60hz, 50hz, or no filltering on temp probes I just synced your master fork into mine. Compiling 13.1...

Sigh. Facepalm moment as I think I looked at the lucid file previously. I've studied the peaks plugin difference would be an active verse passive attempt. It's interesting either way.

2.25 uS is awesome. I'm curious what you changed. I tried to move some of the code from the ISR to Read function ( kind of a top half / bottom half from Linux). As I don't have an oscilloscope I gave up when I couldn't see if anything was improving. Spent yesterday writing a LinkmeterD...

In reply to http://tvwbb.com/showthread.php?46004-INTRODUCING-the-quot-Roto-Damper-quot&p=705356&viewfull=1#post705356 I didn't want to hijack Ralph's thread too much. I'm not sure if the issue was the ADC ISR or the Serial ISR. Either way there are enough ISR events to mess up the determinism...

Did two cooks this weekend. Some ribs and chicken breasts plus baked potatoes. New code worked really well. No idea if it was the code, RD3, or different lump but a couple of times the only way I could tell things were running was the time stamp at the top of the web page was still updating...

Agreed. I've been running something similar to the new shapshot for better than a year. The anemometer can't measure passive airflow very easily was my thought process.

Ralph - Funny you mention the servo screw being tight. I did that at first but I caught when benching testing. Now I use a sheet of paper as a feeler gauge . Dominick - You've got me on the carbon fiber wire never heard of that one. Worried that load on the 5V line could freak out the AVR chip...

Major problem I see with this test is that you have both the fan speed and servo position moving. I've used an optical tachometer and under voltage control the fan rpm will go down to ~45% of rated speed before suddenly dropping into the long pulses when under min fan speed. Fan Airflow is very...

I was running my snapshot. To be succinct the servo was being controlled by the original firmware that delivers full power. I corrected the servo jitter at the ISR level in my code. This weekend I plan to try the latest mainline snapshot with the servo controlled movement code. Unless I get...

Ralph I'm loving the RD3 that you printed for me. I can hold 225F steady without anything in the Akorn. In the past I had to have something to act as a heatsink ( food, pan of water, etc) to do that. Any recommendations on servo grease for frigid temps? Did a cook last weekend ( 10F or so) and...

I really didn't even know how old the pull request was till last week. My whole group got reorganized last year and I got a "promotion" that came with no more pay. Did 12 hours Tuesday because one Sql database shutdown and took out several hundred developers from accessing their virtual...

Looks good to me. Curious to see if this affects the pid tuning due to the varying resolution.

Haven't visited in awhile as life changes. Still had plenty of time of time to do cooks and been using "Fan Assist" or as I called it Fan Offset for over a year in my HM. This all seems very similar to the code I posted in January Fan Offset. I like the overlapping slides but have no idea how...

This isn't my vid but saw this on youtube when I was researching the HeaterMeter. https://www.youtube.com/watch?v=-JCOAqRopGM
