I got lost in life and ended up in NY. The only benefit of living here is that it makes it easier to make a trip a year to Citi Field to hex the Mets. :censored:

My reply was directed at hardware and software development, basically the next generation of the HeaterMeter. The complexity of physically building a HeaterMeter is not in question.

Just my opinion, and no disrespect to anyone, but the complexity of the HeaterMeter has always been its biggest weakness. I've tried hacking at it a few times and always gave up. It's a crazy mix of Arduino, RPi/OpenWRT, Lua, and JavaScript with TX/RX to a microcontroller. The path forward is a...

I've never had much luck with grounded thermocouples. Recently I've been using Teflon-insulated bead probe thermocouples with good results.

It looks like you might have a bad SD card. I would start by swapping your SD card with a new one.

The Sunon GB1205PKV1-8AY with a bit of filament manually extruded into the empty hole works perfectly. I printed the 1" NPT adapter from V2 and it was only 2mm too small, so I warmed the inside of the adapter with a barbecue lighter and press fit it onto the plastic alum-a-damper. PID: 4/0.02/7...

Totally understand about the differences in CNC vs 3D printing. I honestly didn't even check the slices before sending it to the printer; even printed without supports, it's not really a big deal, since the lip around the L-com covers the layers extruded in air. Edit: Wow. I just got back home...

I just printed the top and bottom (top scaled to 2540% to match the bottom), but there's something more going on here. The bottom case doesn't physically fit a Delta BFB0612H (the hole spacing seems to match a Sunon GB1205PKV1-8AY... minus the extra hole). In addition, the hole for the L-com...

I'm printing the disc and bottom right now. When I go to slice the top of the case, it has to be scaled ~2541% to make it the same size as the bottom case. Does that seem correct?

An AirBurner is an awesome upgrade. I've had mine on a WSM 14 for the past seven years and can keep temps +/-0.8F with the standard Delta blower and no damper (the WSM 14 is so small that the natural draw of the fire isn't enough to cause temps to run away without a damper). I have a Green Egg...

Awesome! Is this designed around a Delta BFB0612H and MG90S? Still uses the same two hole disc as V2?

Yeah, it could definitely be kept generic and other boards could be simply connected. There's a couple of issues with this type design: cost and complexity. The TC board alone is over $20 for three. That doesn't include the cost for the quad TC circuits. There's also the ugliness of having...

As more people find unique uses for the HeaterMeter, I think you'll see more requests for an all thermocouple HeaterMeter. I've used the HeaterMeter for everything from barbecue to controlling a heater on my boat in the winter to monitoring/controlling wine fermentation temperature to... you get...

What NickMV said is spot on. However, if you have a gravity fed pellet smoker (i.e., no auger, something like Wang's Gravity Fed Burner) then the HeaterMeter will readily adapt.

No joke. I'm still waiting on parts from when you first started talking about this project... Also, for anyone that wants to get in on this project: stay away from NodeMCU boards with the CH340G chip. WCH doesn't stand behind what they produce and, as a result, the drivers are complete crap...
