Not harsh at all. I really did search on google and HBT, but all I could find was NTC, and could not figure out exactly what that was, or at least not clearly. I must have used poor terms in my search. I tend to over engineer everything, and probably did here as well, trying to be specific enough to weed out the quintillion bogus hits.
The Fast Fermenter has a 1/2 NPT threaded port, and I was trying to use a screw in probe in place of the threaded brass thermowell that came with it. So now that I've got a $35 RTD probe, I can't decide which way to go. My STC-1000+ units are in use on my fermentation cabinet (this fermenter is too big to fit in that), and I have 4 non-flashable ones, and no interest in programming ones I don't have. I may just go with a 'cheap' omega PID step controller. I use them in my business (and my mash tun), and can run/program/monitor the steps from a PC USB port in a matter of seconds. A bit pricy at $110, but I'll spend a third of that on a pre-programmed STC-1000+, and still can't use the lappy to program it. That's requires more hardware and a learning curve. In spite of working with electronics since the early 70's I'm far behind 'modern' stuff being used here! The last compiler I used was for 6809's. Most of you probably never heard of them! And Fortan & assembly on my TRS-80 Model 4, but I digress.
