@TheBloke and everyone/anyone
I am just playing with the eScribe and have a few question regarding to custom coil settings I couldn't figure out without an actual DNA200 on hand:
  1. Is it a must to normalise the TFR to 70°F or any other temp does the job?
  2. Is it just the eScribe display which rounds TFR to 0.X or the sensitivity/precision of the DNA200 is 0.X?
  3. Is there any limit of the input data pairs the board can handle?
Details:
  1. I have tried and it is possible to upload csv with 68°F normalised TFR (which is 20°C metric). As all of my data is metric it would be awesome if I could simply convert the temp. But to do that the board should be able to handle csv where the TFR=1 belongs to 68°F
  2. The graphic display of the custom settings rounds both temp and TFR to 0.X . Which means that e.g. for 316S/S the same TFR is shown from 160-350°F. I take it is just for demonstration only but again, w/o a board and 316 S/S on hand I can't tell how precise it is in the background.
  3. It is also unknown for me how the algorithm behind uses the input data. The display shows simply linear approximation between steps. If this is the case I might want to load a tons of data (i.e. for every 5° or even more) depending on the material. However, it would be lovely to know if there is any particular data size the board is capable to handle. Again, eScribe has no problem with 40+ data pairs but the board can be an other thing.
P.S.:
If 68°F normalised TFR works and the board can handle 0.00x precision TFR wise and able to handle 40+ lines of data it is just minutes to convert all my data to F and make a new tab with tons of simply copyable csv materials. Just sayin'

@ hOOligan

To be honnest i would wait till you can grab a opus or any other mod with this chip over a sxmini. Got both here now and i dont want to start a dna vs sxmini chip battle but this thing is impressive.
Got to say i always prefered the interface from dna boards but damn this thing is great with the profiles and all tweaking you can do. The preheat thingy works great to.
Will still use my sx now n then but i can see it getting removed from rotation completly once there are more dna200 mods available.
Its not like the sx is a 50 bux mod and its worth its money (i guess for those that wantr to spend such money). Sxmini is heavy as bleep to, even with my squape rs on the opus i dont think it weighs as much as the mini alone.

@h00ligan
I would wait too, actually I do wait but for different reason than @Monoxxide
I do love my SXMini even its weight and robustness and I am fighting my shinyitis hard not to buy a Boxer now.
But DNA200 and Escribe promises a lot of fun I definitely don't want to miss even I am quite unhappy with my VS rDNA40.
Luckily, I already have enough TC mods on hand so I can (or at least try to) wait until some super sexy DNA200 is on the horizon. (Boxer with DNA200 shouldn't be too far away either)
However, I more likely will buy a Yihi Boxer anyway, just trying to hold as long as I can and get a DNA200 first

Bottom line:
Evolv just raised the stakes. Everyone will react. The next few month gonna be busy.
If it is not urgent wait and see what happens. E.g. Can Yihi come up with something customisable for the 350j chip or they need to build a new hardware etc.
If it is urgent, go for the DNA200


P.s.: Man, this Boxers are sexy. I couldn't hold it back for long...

Agree vapeaalone on the 2 posts above this. Cant wait to see wats comming, im in the "damn this thing is great" stage still (only got the mod a few days, dont even got all the ins and outs yet).
Great things ahead imho if one not in a rush. I need my ti wire to arive already!
How are the buttons on those boxers in use? Like the look of those to and bet the weight of them is ok to.

dunno. Haven't bought yet. But they say works like a charm. And yes, it is said to be super light.

btw:
It seems that eScribe doesn't allow TCR lower than 0.002 when you set as special which eliminates Stainless Steel.
However, you can add curves with resistance change below this value. The question is how it works for real.

We should ask Evolv to decrease the lower limit at least to 0.001 (and let us to take the responsibility of inaccuracy).
I wouldn't like to use for TC nothing but stainless steel. I know that it isn't perfect (low TCR) but it works surprisingly good on the SXK mods if once you can set it correctly. It's sold everywhere, cheap, durable and seems to be safe. Maybe it's not the most accurate one but my opinion it's good enough.

Well, S/S has ~8 times higher resistance than Ni200 with ~1/4 of the TCR which should give numerically ~2 times more ohm change to detect if you build same length/gauge coils. Eg. 0.09for Ni and 0.77 for S/S.
So it seems that monitoring wise the hardware must be able to handle a well sized S/S coil which leaves the software...
Which means: yes, we should ask. And the only thing they need to add is a warning popup saying that below a certain resistance (e.g. roughly 4 times of the default lower limit) the TC can be inaccurate.

Mat the rate evics are dying the oreorders wont even be fulfilled


I just clicked order on an sx mini m class ajd im beginning to thhink maybe that was a bad move and i should just wait for the opus.

Would anyone recommend the m class is still the go to buy over the cirrent dna200 releases. Namesly the opus? Also i wonder how long the opus will take to get back in stock and what production issues may be present.

From orevious reqding the yihi chip seemed more accurate than the dna 40 and handled temo co trol differently but may oreferred it. I wonder id the 200 chip handkes it the same way as the 40
I bought a SX Mini M and sold it within 3 days. I replaced it with a Boxer and now that I have more experience with the SX350j, the only thing I like is the auto rotation screen and maybe the dual batteries for longer runtimes. That's it. It's inaccurate and burns my wicks all the time (set at 385°F, 20j). Never had that issue with any of my DNA40 mods.

No more need for my SX mini, sold it. The DNA 200 and Opus is superior for me in every way. The new Vapor Flask is getting a sx350j chip and while I understand why they made the move (form factor, DNA40 rep) it will be a long wait until I get a Flask 200. The next Opus batch may be out before the VS200, I recommend it and especially if you want a US product.

I have an Opus, so you can maybe take what I have with a grain of salt. I also have an IPV4 that I love. The IPV has a Yihi chip as well, although I certainly understand it is no SX350J.

Given the price of the SX Mini and the Opus, I would say go with the Opus. It really is not that much bigger, the battery life is likely similar because the M Class is on a single 18650, and the Opus has all the power and customization/tuning options you could possibly hope for. I was thinking about getting an M Class until I saw that there was a DNA200 mod out, which was the Opus, and I couldn't be happier with it. If I bought the M class, I know I would have regretted it as soon as I started seeing everything that the DNA200 could do (beyond just the power difference), although that's just me (I get bored with things quickly and always want the newest/most advanced).

Although we'll start seeing rather soon, I imagine the only difference between the Opus and any upcoming DNA200 device will likely be aesthetic/size or in the battery, and was really, really surprised and happy with both the size, looks, quality, and battery life (although it could be slightly better). That all said, I know there are a lot of people equally happy with the SX Mini and don't want or need the extra power or features that the DNA200 offers.'

Edit: Oh, and the Opus is from an American manufacturer with a six month warranty (something others probably could not care less about, but both of those things are fairly important to me). When I ordered my Opus, they said the next batch should be out soon and that was over a week ago.

I'd love to have an Opus 200 but I also wonder if yihi can update the m-class firmware to be very competitive with it. I sold my m-class (shipping it out today) but yihi was thinking ahead when they implemented the firmware update capability. But for me, I've tasted the koolaid and its all evolv for now lol.

There's a lot more to the DNA200 code to be as customizeable as it is. I doubt the SX350j can be as flexible w/o a serious rewrite of the code if it's even possible (hardware limitations?).

Evolv always had the best chips on the market, even with the mis-steps with the DNA40. The DNA40 is still a better chip than the SX350j, IMO. The DNA200 is in a completely different class.

I'm still tempted to get the Opus200. Glad it's out of stock everywhere :lol:

I am either dreaming or dead and and it is the heaven or accidentally took something or perhaps Santa actually exist and his midle name/s is/are John/James/Brandon as after a few minutes I asked I've received this:
"..We'll change the (TCR) minimum to .001 in the next iteration of EScribe to accommodate.."

P.S.: The issues of my relatively early rDNA40 made me swore that no more pre-order and/or early adoption especially if evolv involved. Therefore, being a man of my word as a decent grown up should be, I am responsibly going mad that I couldn't pre-order a GV Boxer DNA200 blindly and preferably yesterday.
I want it and want it NOW!
First world problems, lol.
