    Servo Driver Circuit (possibly dead?)

    Never mind! I figured it out! I'm flashed back to trusty old v12! Looks like I'll be smokin' again this weekend!

    Servo Driver Circuit (possibly dead?)

    I can't get the fight back in my servo. When I was v13, my main page said: OpenWrt | OpenWrt Attitude Adjustment 12.09 | Load: 0.03 0.04 0.05 So I tried to revert to backup image from February of 2015 and now my current load says: OpenWrt | OpenWrt Attitude Adjustment 12.09 | Load: 0.10 0.04...

    Servo Driver Circuit (possibly dead?)

    So you're saying that I'd put +/- 5VDC on the Red and Brown, respectively, and then send the data signal on the orange on the MG90S Tower Servo everyone uses? Could I steal the 5VDC from somewhere on the HM board and just break the traces on board and run wires to the jack?

    Servo Driver Circuit (possibly dead?)

    Thanks, Ralph. That's exactly the problem I'm seeing. They work fine when it's just the servo and no damper. However, since my dampers are so large they are not the smoothest running and can still be in motion after the time out during movement. Unfortunately, when it times out they tend to...

    Servo Driver Circuit (possibly dead?)

    I have two different servos that are not working properly and I figured since they both used to work and now neither work, something is wrong with my HM 4.2. When I have the servo apart and set temp so that the servo is either 0 or 100%, it will go to either position without issue. Together...

    Whomper Damper

    That's the only way I could get this thing to work right. I'd initially gone off of the settings that I had for another damper and kept changing them little bits at a time and was seeing massive oscillations so I went through the PID tuning methods (made an Excel Spreadsheet w/ the formulas to...

    Whomper Damper

    Steve, the're in the first post and I haven't messed with them since calculating them based on my prototype. P=30 I=.0227 D=95 What I find affects this thing more is how open/closed the chimney is at this point. I keep the stock BGE chimney about 2/3 of the way open and then make one or two...

    Whomper Damper

    No, we're closer to you guys in Richardson. The BGE didn't get hailed on as it went just north of us on Monday but it looked like it was going to be a big one. I never even thought about BGEs getting hail damage but with what Wylie got, I'm sure some were injured. If you're in my neck of the...

    Whomper Damper

    Kenny, no problem. Happy to answer questions. I know that all I did on this forum was ask questions during my first HM build... I didn't remember so I logged into onlinemetals.com and found the order: 2.5" OD x 0.065" Wall T316 Seamless Stainless Tube 1.75" OD x 0.065" Wall T316 Seamless...

    Whomper Damper

    I forgot to answer that--someone walked into my office. Yes, for falling embers, I use the stock BGE screen. The sheet metal is cut (I don't remember the exact dimension now) exactly such that if you insert the bottom of the sheet metal into the draft door tray that it will go all the way down...

    Whomper Damper

    Kenny, the internal is just that white part and it is 3D printed. It just sits on the standard servo (MG90S sound right?) that all the guys seem to be using and the servo is fitted into the red part that also houses the network jack. It has a key on either side so that the whole deal doesn't...

    Whomper Damper

    Benjamin, I haven't been following the forum that much lately but I'll look up this flatdamper and check it out. I'm interested to see what other folks are trying for sure. One thing I did do that I wish I had a picture of... I took a piece of sheet metal and welded a hunk of tubing to it and...

    Whomper Damper

    Guys, I wanted to share some results. I finally have the new stainless steel whomper working nicely with some minor adjustments and this past weekend's cook went really great. We had two parties on Saturday (hence the pork butt's names) and I decided to do pork butts for each host. Both...

    Solution for mounting SS pipe onto SS dog bowl?

    Don't use JB weld for cooking unless you just don't mind polymers in you food. Get a MAPP Gas torch from Home Depot and some 56% safety silver from your local welding store and you can stick stainless together just like soldering copper pipes.

    PitDroid: An Android app for your HeaterMeter

    I'm guessing that this is not you, Colin: http://smartwatchapks.com/APK_PitDroid_smartwatch.html I was doing some searching and found this and it looks sketchy huh?

    Whomper Damper

    Well, this is finally done! Between moving out of our house for a fairly extensive remodel, having a new baby boy, already having another toddler, it's just been tough to find time to get this done with all the other things I've been working on. So here it is. The finish isn't perfect and...

    Flat Damper

    Bryan, You can get 316 Stainless Sheet from OnlineMetals.com and have enough to make half a dozen adapters. You can also get stainless tubing in 1' lengths for a reasonable price. Now if you want to get fancy and combine the two without a TIG welder, you can simply use a MAPP Gas torch from...

    Whomper Damper

    I'm still working on this despite the move to a new house and getting things done there. One step at a time I suppose. I need to tack on an adapter plate for the BGE and do a test run. I'm hoping to do a brisket or pork butt the weekend of the 17th with this guy before I braze top on...

    Whomper Damper

    We've been moving from one house to another but this weekend I got to at least smoke a pork butt and I wanted to update on this project. I'm still stalled with the stainless steel version of the Whomper but I used my prototype along with the new guts that go in the SS version to see how they'd...

    The LinkMeter Snapshot and YOU

    Bryan, didn't you say that there was an auto PID thing going on in the newer snapshot too or is that something else? Thanks again for all of the hard work.
