Managed to get my HM 4.2.4 assembled tonight and can log in. Pit thermocouple and 3 probes reading accurately.
Unfortunately it was not in a case when I decided to hook the fan up and, as I was soldering, the solder reel shorted a part of the board. The screen went a bit crazy and the short lasted a couple seconds before I reacted.
Plugging in the 12v power supply now produces an audible buzz in the piezo speaker (the 5v on the RPi does not however). Everything seems to be working and I can log into the linkmeter software. The screen is fine too. On reboot after the short, the thermocouple was way off but reinstalling the software on the SD card seemed to bring it back in line even if it seems a bit less accurate than before.
However, upon further testing the fan will not stop even if the pit temp is above the threshold. Maybe I am not setting things up properly but my gut says something is wrong. I'm doing all my testing at room temp (~74f) with a threshold set below that.
Am I screwed or is there hope for this thing? I'd love to not have to order another kit! Unfortunately I have no access to a multimeter nor could I troubleshoot the components myself.
Thanks for any advice!
