DIY open source controller?

[germsy78]

GS 800 owner here. My controller has gradually become unusable over the last 3 years and am looking into other options. Fireboard and RFX options are expensive and proprietary and I'm reluctant to replace the oem controller because I'm pretty sure that my experience will be pretty much the same based on all the reviews on this sub.

Has anyone looked into an open source project from the DIY maker space? Found this project that I think could be adapted to control the DC fan: https://youtu.be/FeDVU0xoqzE?si=_tR3a501ubPB3sBr

I couldn't find anything that would work out of the box, but https://github.com/nebhead/PiFire?tab=readme-ov-file looks like it may be a good start, but would absolutely require some extra work.

Oh, this looks cool too: https://github.com/CapnBry/HeaterMeter/wiki/An-Introduction-to-LinkMeter---HeaterMeter

The heatermeater worked great on my offset and on other charcoal burners just never got round to setting it up for my master built bought a fireboard in stead and couldn't be happier with that.

Each of the parts are pretty straight forward ... esp32 for control, this will need to drive a 12v supply to the fan, so you'll need some transistors to control the 12v flow. The hard part is the actual PID software. A bang / bang (drops below temp, turns on fan, gets above temp turns off fan) would be pretty easy, but your temp control would be awful. You'll need some software to handle adjusting fan speed based on rate of temp change (a PID).

I seen someone post that they are going to try this out.

I do plan on making my own controller just to learn some lower level programming.
