I've only read several threads, the last one I wound up on github where I'd have to buy 3 boards but it didn't see the price and wanted me to log in.

If someone could point me in the right direction to get started I'd sure appreciate it.
 
Github would be the place to get all the info about the heatermeter from getting the pcb made, buying the components from mouser and how to put it all together.

A couple threads down, Peter is selling a 4.1 pcb. You could get one of those, or you if you buy from OSH they will require a minimum of 3 boards for about 40 or so. You could always sell, like others, the extras 2 you may not need.

In a couple of weeks, or sooner, version 4.2 will be available to build, which has a lot of improvements and if you are able to solder smd parts, you can use thermocouples for the pit
 
I'm "OK" with SMT soldering.... I don't like it, and it might be a good thing I have to buy 3, especially if I have to use my Aoyue 2702A+ (I've burned a board or two over the last 2 years).

I suppose if I do it I'll probably buy & build 3, or give one to a friend to build for practice. Really though it looks like I have a lot more reading to do - I just really like the display, networkability, etc. Even without the controls I'd like it for monitoring.
 
From what I can tell the 4.2 version is good to go, I would wait for it to be officially released in a week or two. It was my first attempt at SMD and even though I had to redo it once, it was not that bad, just those caps and resisters are so dam small. The Wifi and there is also an Apple and Android(PitDroid) app.

if the whole board is SMT (I guess SMD), I think I'd rather go with the older version. Sooooo much easier - can hardly identify the components.... I have to source/fix stuff like this from time to time---not fun. We have a camera that's like a magnifying glass crossed with a microscope- cheap/easy/nice. Still sucks.....only reason I'd go with surface mount is for max production.
 
The HMv4.2 has the OPTION to run a thermocouple pit probe, the main advantage of using a thermocouple is they can go to much higher temperatures than thermistor probes, which is awesome on a Kamado but totally unnecessary on a typical smoker. As John said, there is a small (8-leg) IC and a half dozen resistors/caps that are SMD on the HMv4.2, but they are all for the thermocouple support, if you run a regular thermistor pit probe you do not have to do any SMD soldering at all on the HMv4.2
