Well, half of it will go in the freezer right away.
Sorry Mike, it doesn't work that way. I thought the same thing about using percentages of error with cold res to calculate temp errors until I read this thread.
TC beyond Ni200: Nickel Purity, Dicodes; Ti, SS, Resistherm NiFe30; Coefficient of Resistance
"TheBloke" and "Balask go into detail with mathematical formulas why this is not true. The formula our mods use to calculate coil temp from res change is not linear but rather a product of the TFR at a given temp in reference to the cold res.
Bottom line is we're dealing with non-linear multipliers and even those based on different TFR values for each wire material type. This is why I keep insisting that a .010 ohm error in cold res is huge. For SS it will cause upwards of a 50°f error at our normal vaping temps and with Ti much more error still, 80°f plus.
I did understand the math at some point during my stay on that thread but I can't quote the formulas now. Anyway, the formulas on that thread are not too complicated and will be useful to you based on the direction you're heading with TC enlightenment.
Yeah, I am curious myself. I just love the cinnamon sooooo much, but cherry/cheese sounds pretty damn good too.let me know how that turns out
I will read through it when I get a chance, soooo many projects, so little time.
I am interested though. I have an inside tract to validate how at least one certain company does it. I wouldnt even ask the questions though until I knew enough about it not to look totally ignorant.
not a fan of cinnamon and/or chocolate
been looking at the fruit hamantaschen!
Different set of circumstances, because I did NOT look closely at the mod resistance on this particular mod when I did the test as it had been set long ago:
The atty being used is Merlin RTA with a 3mm coil, 5/6 wrap, of 26awg SS430, using the TCR from the Steam-Engine site.
The Mod being used is a DNA250 that I built myself. Accuracy of the mod was checked by using a NIST traceable thermocouple/meter. I measured at a variety of temperature settings. Each reading was repeated twice. Here are the results.
- DNA set at 300, Thermocouple measured 307
- DNA set at 350, Thermocouple measured 349
- DNA set at 400, Thermocouple measured 393
- DNA set at 450, Thermocouple measured 442
- DNA set at 500, Thermocouple measured 485
- DNA set at 550, Thermocouple insulation melted before reading could be obtained
You know, something occurred to me after watching excerpts from his vid (all I can handle is excerpts, or I go brain dead). ALL of my devices, I seem to be running hotter settings now than I used to, not just the 60/75 series, but also the 200/250 series.
They have changed Escribe, and issued service packs for just about every device recently. I wonder if the new "curves" are just different across the board on everything????
Now, I run beta software too, so some of that could be beta issues.
Anyway, just an observation.

I'll gladly take a break from C-Span and watch Phil, don't know why I subject myself to listening to some of the brain dead people we put in office.....
Interesting, I've noticed I've had to back down my settings from what I was used and I haven't changed a thing on my builds.
I don't have a day to kill, although it's kind of hot to work outside today, but I couldn't watch the whole thing. My take-away is that the boards perform as advertised and within tolerances. I haven't seen exactly how he's measuring temperature, IE probe and instrumentation, so I'll reserve judgement there other than to say if he's running at 500F he needs to do some reading of a certain thread.
It's funny you say you've raised temperatures, Mike. I've lowered all of mine and spent some time in device monitor to keep things matched, temp versus power. I was vaping at 480 or so on most everything, but have found I'm just as happy at 400 or lower. It can also be a function of "mood" so the jury is still out.

That was a well done video by Phil, long but there is a ton of good info, more then I needed to know but I also discovered things that helped me understand what's going on, things I wondered about. I do wish he would have given a quick comparison with the 200 and 250 during the summary but I don't think Phil does quick which I guess can be a good thing. One thing I walked away with, it really peaked my interest in the 75C's..... ugh....
Interesting he talks about having to bump the temps to get the same vape he's use too. Here's what's my experience has been, overall now I'm vaping max 430, I use to vape around 460 sometimes 470. That said during the day I do have to bump but it's still lower temps then what I use too vape at. I chain vape, I'll start out usually around 390-400 and as time passes I have to keep bumping the temp up to 430 at 5-10 deg bumps then I'm at a consistent vape for the day. Many times I'll go to bed, fall asleep with the mod set at 430 and when I wake I'll take a hit and it's holy crap, pop fizzle, I have to back it down to 390-400 again. I think it's a combination of temp's of the mod, atty and saturation of the wick, that's with each and every one of the seven 200's and the two 75's I use.

Interesting to read your post after I posted mine.
I also agree, too hot to work outside, it bugs me with the stuff I want to do but I take the dogs out to pee and like them, yup, too hot, let's go back inside where it's cool.
hey, mike! katz is branching out to brooklyn - maybe, next stop: martinsville!
Cute, and smart.
Bur Martinsville wouldnt know a good pastrami if it bit them on the azz, let alone what a babka or pierog is.......
I get that on mine too. Even in sleepy stupor I have learned to do a 1 sec pulse FIRST to see if the devil is showing his .... or not.
