In a quote above, Brent said "DNA is the best, but they also never designed their chip to tc a semiconductor in a configuration that would normally be a short circuit."
Also, not sure the SiC is connected by wires. They may have molded the legs to fit into the deck.
Thanks for reminding me of what Brent said about this
@Accept, I had totally forgotten! (Too much you know what.) My only point about the wires/legs is that there are only two of them, which rules out the possibility of a thermocouple or other onboard sensor. Plus we know the SIC will work on other mods, so the basic operation has to be the same for TC: closing an electrical loop, monitoring resistance changes, imputing temperature from those changes, and moderating the current accordingly.
I think you're absolutely right, though, to quote his remark about doing TC with a semiconductor. I'm not sure how a semiconductor in a circuit could be read as a short circuit, whereas a conductor in the same place in the circuit would not be. But I think the major relevant difference between a conductor and a semiconductor is that
generally a conductor's resistance increases, but a semiconductor's resistance decreases, with increasing temperature. ("Generally," because some materials have positive temperature coefficients of resistance in some temperature ranges and negative TCRs in others.) So for a mod to be able to do TC with the SIC, it would have to accept negative TCRs, not just positive ones. (That is, you should be able to define line segments in the TFR file with negative slopes, not just positive ones.)
If a mod can't work with negative TCRs and impute an accurate temp from them, I would think that it can't do TC at all with the SIC and can only work in wattage mode, and that Brent would already have touted that as an advantage of the new mod. But I'm just exercising my curiosity in the presence of a mystery. I'll be very interested to find out what the new mod's secret sauce might be!
