The heatermeter case that Bryan designed is customized to fit what ever pi you need. You just tell him which pi your using and if using a thermocouple or not at check out and he'll print the version you need.
If you're printing them yourself you can use the "Open in Customer" option at...
PSA: Make sure you don't mix up the servo power and position signal wires (red and orange) within the connectors! I fried a pi last night, and not in a good way.
Also, is the 3mm plug not ment to be taken in/out when the HM is powered up? Because doing so was causing the arduino to reboot...
Lol that's kind of what I was thinking too. I'm guessing the nozzle was too far from the bed for the first layer or something like that. The bottom right corner is also warped or lifted up, same for the back of the case as well. But somehow the inside surfaces all look good and the dimensions...
So I picked up one these probe spools from Bryan's store, this thing is great! I wish I had this thing 10 years ago.
Got me to thinking, what about an additional "spool module" designed to hold a wall wart? If I had the 3d skills to draw something up I would but I'm still trying to learn.
I...
Good to know, I'll pick up a 2A supply. In the mean time the 1a does power up the HM without the servo/blower attached yet.
I sent Bryan's case design off to my local library to have it printed up and boy did they screw it up!
I asked if they could give it another shot... If that doesn't...
FWIW I use the servo/damper only, without a fan even installed, on my large bge for low and slows. Works great!
My thinking is that for low and slow on an efficient ceramic grill with such high thermal mass that a damper is all you need. If you're running at higher temps or a weber for low and...
I've ordered and been receiving parts for a new hm build and got my power supply in today. This will be a more standard build, my other build is a sans-rpi hack job so my following issue hadn't come up.
I ordered this 12v/1a switching supply off adafruit: https://www.adafruit.com/product/798...
Been a while since I've been on the heater meter forum but nice to see a smokerbuilder.net build going on over here! I've been thinking about building one of these cabinet smokers.
How hot does the heatermeter shelf get? how hot would it get if it were enclosed some what for weather protection...
I wouldn't worry about the .ino.
Compiling for the uno should be just fine. No need to be too worried, it wouldn't be a big deal if it were wrong, you can always reflash it.
I like it. I wonder if those servos have enough torque to operate a BGE damper. Mine is pretty 'stiff', I imagine because of its curvature where as that primo damper looks flat.
What ever floats your boat!
If you want to go down the "customize heatermeter code to work for pellet" path it'll probably be easier to not to worry about the ADS1115 as the noise is already handled. But for a from scratch project, + an ESP, sounds like fun to me.
So you're bypassing the onboard voltage regulators/caps. Maybe this is part of the issue, try powering through RAW with ~7+ volts?
Also, what's that cute little resistor under the 10k ohm resistor?
For the record I'm using a 5v pro mini as well without these issues. How are you powering the mini?
In your code have you tried implementing heatermeter's methods? Specifically analogReadOver? (grillpid.cpp)
As far as I can tell the heatermeter stores both a temperature reading and a...
