I routinely hook my HM up to a Morningstar charge controller in my outdoor shed. I use the stock blower and a servo. Hooked to the charge controller is a 15W solar panel and a boat/marine deep cycle battery. I've cooked for 12 hours+ with it, no problem. I have not tried to do it without the...

Can anyone with both the "new" probe designs (like the High-temp air probe) and the original high-temp cooking probe comment on the difference in diameter of the round black part of the probes? I purchased a few of the "original" designs with just the black plastic part (no metal like the new...

I know this thread has talked a lot about Li-Ion type batteries but I wanted to throw in a couple of points and ideas on the lead-acid types. Many years ago (and much before I got into HeaterMeter) I outfitted my outdoor shed with a small solar panel, charge controller, and storage battery. Its...

I have a kettle with an copper pipe "air burner" situated just below the charcoal grate. The air output holes are drilled at roughly 60 degree angles (0 being straight up). With a load of charcoal on the charcoal grate , I've never had ash blowing around. With the "burner" distributing the air...

Thanks guys. I think the doneness was just about right given your descriptions, perhaps slightly toward overcooked in spots (a couple bones fell out on their own). The outer layer of meat was dry, which makes me think had I used a water pan, it may have helped the moisture level there. The...

Hello everyone, Tried ribs for the second time yesterday. They were each ~3.5lb St. Louis cut spares. While they looked decent and more or less tasted good (flavor wise), the texture wasn't the best. The outer layer was a fairly tough "skin". The meat between bones was ok/tender but somewhat...

Yes, a bigger battery like that would be the way to go for longer cooks and still maintain some portability. The reason I chose the one I did was quite simply its size, weight (or lack thereof), and included a simple charger. A 12 Ah SLA battery definitely weighs more and likely needs a separate...

I know there are several people interested in the battery performance but unfortunately, I’ve not had a chance to conduct a proper “long” cook, ie. 5 hours or greater. Instead, I did a “bench test”. On my workbench, I fully charged the battery and set the HM to max fan 50% and 150 degree set...

I thought I'd share my experience so far on a recent acquisition for my HM... specifically, a rechargeable battery unit. The reason is simple... avoid having to use an extension cord to run my HeaterMeter and thus quicker setup and put-away. The first step was to get an accurate measurement of...

New feature request: A clock shown in the HM LCD "rotation" of probe temps. Clock time could be set via NTP server so that it's always correct. I started keeping better track of my cooks by way of a "cooking log" which I keep on a table next to my grill. Having the time rotating on the...

My HM has 22k resistors (due to my slowly-dwindling stash of ET-732 probes). I've been replacing with the Thermoworks probes. As long as you set them properly in the config, they seem to work fine. I do believe the temp curve is somewhat more limited on the higher end, but since I use them as...

Before I forget Bryan, I noticed one thing this morning when I was testing this final modification out... I kept bouncing between the current/stable HM firmware .hex file to see the noise icons (or lack-thereof) and the noise-graph .hex file to see the actual noise range. I noticed that the...

Well, I cut the 3 probe traces and soldered in the 100k resistors and capacitors. It actually was pretty easy once I knew what needed to be done. The most important part is: It worked! The noise graph, only "bounces" between 2 maybe 3 ADC values now with the fan running... before it was...

So if I understand your post right, is the following correct (for pit probe only)? 1. Cut trace shown by dark blue arrow 2. Replace trace with 100k resistor 3. Place cap shown by light blue curve (marked with CAP) - I assume I could use a ground point closer...

I *think* the noise firmware Bryan listed is working. I get this for my pit probe (ET-732 probe with grounded braid): This is food 1 (Thermoworks probe): In both cases, this is with fan plugged in but not running. This is with fan @ 100% (which is 45% max in config): P.S. This...

Thanks Ralph. The twists, if my cable is standard, are not mixing servo/fan with anything probe-related. I will try another CAT 5 cable just to make sure it's not that. On the RC filter idea... that seems like a good idea and I had read about that in another thread. When I read the schematic...

Pictures: HM board, CAT 5 section. Wiring is as follows: 1 - Pit Probe + 2 - Probe 2 + 3 - 5v for servo 4 - Ground (for servo & fan) 5 - Blower + 6 - Servo pulse 7 - Probe ground (all "front" pins of jacks connected here) 8 - Probe 3 + CAT 5 Surface mount "breakout box", with lid removed...

Thanks Ralph. I have a hm 4.1with the white wire and led 1 mods. I'm not sure the specific version number but it was an early 4.1 board. I'm running 3 probes, servo and blower over a short 6' cable for now. The probes themselves share a ground and wire in the cat 5. The servo and fan share a...

I wired up a small break out box to run my probes over cat5. It works but it introduced noise into the probes... Ui showing noise icon and some jagged temps. Probably not a big deal but I'd like to fix it if possible. I remember a while back a special firmware which included a noise graph that...

I adjust my max fan speed once the setpoint is reached, so this would be a useful addition.
