Evolv DNA 75

[Kilinje]

Thanks for the super-fast answers! I love how smooth the power delivery is on these, the 3 click lock was the one annoying item

Agreed, I've only had my Therion for about 2 weeks & can't see myself buying a non dna device going forward (I wish I'd invested in one long ago)

That's the way it's been for me. Every since September of last year (iirc) when I bought my first DNA mod, I haven't bought anything but more DNA mods.

I like 3 clicks to ON. Button will last longer over time then 5 clicks.

I tell people this all the time. My first DNA was a VS rDNA40 over 2 yrs ago and have only used Evolv powered mods regularly. I've tried SX chips and lately the Pico, Mini Volt and Target Mini. The TM is the closest you can get to a DNA experience. The Picos were back in their boxes within a week. The Mini Volt is collecting dust and the TM is what I grab when I run around town sometimes. I just ordered 2 more Silo 1300 cases to build DNA250's when the DNA250 boards are available next month (hopefully).

I believe the on board buttons are rated at 300,000 or 500,000 clicks so they should out-live almost any mod. That said, I have all my DNA200/75's set for 3 clicks but for the convenience and speed.

Same here, 3 clicks for convenience.
Same here, I've been buying dnas mostly. Do have an SXmini Q class but in TC mode it can't hold a candle to the dnas. And that SXI-Q software? What a feeble attempt to appease my need for customization.....

500,000 clicks is not that many. Check the puff counter and multiply by 365. On the bright side the switches must be generic, available from some supplier. A skilled electronics technician should be able to replace it. That could become important in this age of stockpiling.

I have yet to buy a DNA mod. May be it will be the 75. How is it so superior to my beloved Pico and VTC mini. I'd rather not stockpile 10 $100 mods.

Question for experienced dna programmers:
I have always manually entered the tcr value in the "materials" tab in escribe. Always linear and have never used .csv files from SE or anywhere else. Am I missing something? Is there an advantage to using curves?

I let a friend try an Evic Mini and DNA75 with the same Armonaizer with dual ss coils, same settings, he described the difference as night and day. The DNA was so much smoother, since he has bought several DNAs and I have sold the Evic.

More accuracy & consistency, if you look at the curves you can see most metals do not have a linear TCR, especially SS and Ti. EScribe will make a curve from your TCR anyway so there is no benefit to a TCR.

I say do it, I was the same, I've got a load of affordable (cheapy) mods & was taken in with the looks of the Therion & my reaction was WOW. The difference is night & day imo, especially on temp control which is what I predominantly use. To the degree that I can't see myself buying another non DNA device.

The other thing is, it's also great to have a mod you can fully customise & is kind of future proofing (the way I see it)

So .csv curves are primarily used to compensate for non linearity in a wire's tfr at given temps?
Escribe has not changed my custom material tcr values as far as I can tell. They were all entered manually and the curve "appears" to be a straight line. I haven't used .csv files yet but maybe I should?

Yes on all points

So that leaves a question to ask: if my preheat power is set high enough to reach temp in less than @ 1/2 second (as it always is) will I notice the curve at all; except maybe that set temp is off a little?

It gives accuracy up to the limit of 600 F and people vape between 330 F and 550 F from what I have seen. TCR for materials vary in their accuracy, so for an individual you should get better temp matching between materials and for everyone they get the most accurate temp reading they can do.

If I go to SteamEngine and get the TCR for Ni200 0.006 and put it in my spreadsheet and pull the numbers to match the numbers in the TFR curve I get avg 5% error & max error of 9.75% in the vaping range, the values are resistance BTW.
Temp F TFR TCR ERR %
212 1.348598 1.48 -9.7436
302 1.635654 1.78 -8.82496
392 1.922710 2.08 -8.18063
482 2.308764 2.38 -3.08547
572 2.704476 2.68 0.905011

Makes sense. I've done the same thing with Ti and Nife52 in the past and saw no need to run curves because of fast ramp times and the fact that not much vapor is even being produce below 350°f . I'll clean up my materials list in escribe and download some csv files to try.
Thanks for the info.

Trying to cleanup my "on-device" materials list to no avail. The new escribe software won't let me delete all the materials from the list. Any ideas?

If the material is being used in a profile you can't delete it.

What I did was select Ni200 for all my profiles. Then clicked on Upload Settings to Device at the top of Ecribe. Then you can delete everything but Ni200. Then load on everything you want and select it for the appropriate profiles. Finally click on Upload Settings to Device.

Cheers,
Steve

Go into each profile and change the material to one that you want to keep. If a material is being used in a profile you can't remove it from the mod.
Then go back and put in what ever you are wanting.

 

[Mactavish]

What's wrong with the Escribe wire defaults? They work great for me. I only add ones that were not included or are odd.
