DNA 200 Watt

I'm pretty sure all temp protection mods track real time resistance. No other way I'm aware of to achive TP.

Isn't that why Yihi uses the PWN (or whatever), to avoid real time resistance monitoring?

I was under the impression it used the pulses to read the resistance and tune the chip accordingly, am i mistaken on that?

I don't quite follow your point - you say "avoid real time resistance monitoring" and then you say "uses pulses to read the resistance".. I don't get the difference? Isn't using pulses to read the resistance the same as real time resistance monitoring?

It's just the method of monitoring the resistance that might be differing (pulses versus direct DC), not the fact that resistance is being monitored.

In any case, TC as we currently use it cannot function without live resistance reading, so it's certain that Yihi chips do track the live resistance in TC mode (unknown if they do also in VW mode.)

. . .

I should add though that I learnt recently that some mech users vape on Titanium (whose TCR is very similar to Resistherm - 0.0035 vs 32). Both because it's a nice coil material, and because they like the gentle rise in resistance which causes the power to taper off over the course of the vape. Sort of like a bare-bones type of TC So there does seem to be precedent for using mid-TCR wires for VW/mech vapes.

. . .

Interesting! You could build a bit lower than you wanted, say .2 instead of .3 and it would be like a bare-bones preheat. Interesting, indeed.

No i get that and wasn't implying that it didn't have a "real time" monitoring.

I suppose it just comes down to debating the semantics of 'real time monitoring' as in my mind that correlates to "constant monitoring", if something is monitored without pause/breaks that is what i would consider 'real time' whereas the pulsing, by nature, defines it as having a "break" (albeit very short) therefore not "constant".

Now i've just confused myself...lol

Aww if I'd known you guys were going to miss me so much I'd not have left you! Then again, they do say that absence leads to the fondling of hearts, or something like that.



That's fine if you only ever plan to use Ni200. But you shouldn't only ever plan to use Ni200 because other TC wires are better. So you will need the PC at least to set up your profiles for the other wires. That remains the DNA 200's big weakness - for all the magic the PC stuff allows, on-mod it's not hugely changed from the 40. The extra watts may or may not be a benefit to many, but likely won't be a vast benefit (I haven't fully tested the pre-heat yet, so I'll reserve judgement until I have.)

But the ability to TC vape other wires is a huge benefit - and with the programmable TCR curve, the 200's implementation is the most sophisticated available. Ditto, the ability to configure the Static Resistance of the mod to get a dead accurate resistance reading for the atty. So the TC on the DNA 200 should be by far the most accurate of any mod thus created.

But sadly all that great stuff is restricted only to PC only for now, at least to configure it. At least they did allow the ability to change profile on the mod which is a good step. But not the Static Resistance stuff, which isn't in a profile so will require re-setting on PC each time.

So for now, in my view the DNA 200 only shines with the PC access. Without it, it's a 40 with some extra watts and therefore a bit disappointing. With it, it's the most sophisticated chip currently available - though not necessarily the most usable.

I will be raising feature requests for all the stuff I think the 200 needs to be out and out the best without qualification, as soon as I get a chance (next couple of days.) But I doubt we'll see the PC tether disappear any time soon. For one thing, they're pretty limited in how many more controls/options they can add to the mod with the current control system.

PS. I knew you'd not last more than a few days before you got one Did you re-mortgage the wife?

TBH, the fact that the majority of options are done with the software is a plus to me, not a con. As you know, I'm not a big fan of menus (lol) so I like the idea of tinkering to exactly how I want it, saving it and then enjoying my vape. I don't change things with my vape too much, usually set my airflow and power and leave it. If I want to change something, I like the idea of using the computer because A) the software can get way more in depth than a mod's interface ever could, and B) that leaves my mod's interface clean and simple.

I just thought they were incompetent and couldn't put out a clean signal .

I just tried and it does read the resistance in real time with kanthal.

 

[TheBloke]

Oh, and to add to my answer to windx's question regarding "vaping Resistherm on a VW mod" - I should add that the two times I did that, it was on mods that record base resistance in TC mode )DNA

No i get that and wasn't implying that it didn't have a "real time" monitoring.

Yeah I see what you mean. Though technically nothing digital is ever 'constant' - even a direct DC signal has to be quantised by the computer into discrete measurements But yes that would still be far more frequently updated than a pulsed signal.

I just tried and it does read the resistance in real time with kanthal.

On a Yihi? What test did you do?

I just tried too actually, on my SX Mini M, and could see no sign of it. I held down fire on a Resistherm coil and both the on-screen resistance and the volts showed static.

The on-screen resistance not changing doesn't prove much, but I would say the volts not changing does indicate it's not re-reading the resistance; or at least, if it is, it's not adjusting for it.

So be interested what you did/saw?

 

[nic_fix]

that's strange. the volts change on mine. I am not defending this thing! I will have the dna200 asap. beta testing is a very good thing but for my sake I wish it would have just shown up. I bet this thing is more complex than some people make it to be. say it only has 8k there can be a lot of code in that. I was just guessing on the rom too, it could be 64k!

I do it. Pretty good. The smoothest preheat and self-regulation ever Just a bit tricky to calibrate. I.e. find out what build u need.
Btw: Is there any way to tune or turn off preheat on the DNA200? I really don't like the way the DNA40 preheat works and definitely don't want to buy anything with a similar one.

Yep..you can set the preheat power...the time of preheat etc. with Escribe. Pretty cool actually.

Thanks. It seems that I will have a dna200 eventually

So you're basically saying the health of vapers who use Mac or another platform is less important.

{Moderated}

I am mostly joking with the above statement.

so I brought out the old vaporshark. put a nickel build in my brand new velocity clone RDA. dna wouldn't fire it. kept on showing low battery with a full battery meter. alot of fiddling and cursing and thinking it was horrible made. shoved a clapton dual coil in there. still errors and .....

I put the battery in my charger....2.6 volts. yikes. I am surprised my charger decided to charge it from that low. currently it's at 3.7 so I think it's fine(VTC4). I am surprised the DNA didn't give me a EMPTY battery bar instead of going low battery while showing a full battery bar.

Yes, on a Yihi (Boxer mod, SX350j dual batteries). When I hit fire, it reads the resistance. I don't know if it reads it constantly (probably not).

Well to be fair a chip doesn't really expect a resistance change with non-TC wire so I can forgive yihi for not constantly reading resistance of a kanthal coil. that .0X change isn't going to do much on kanthal.

A good test I guess would be to fire a coil and loosen up the atty on the 510 to see if it changes the resistance.

True. It does read every time I fire.

 

[Darkly spectr]

man after I get the DNA 200 build il probably build a 350J box. and then probably a mech box.
and than start my empire of exotic(to muricans) belgian boxes

I feel sorry for your company. If people's glasses are too hazed to see what's happening I really don't know what to tell them. Obviously the Mac version will be out within the next few months. What evolv has done is hire a programmer to write the program and then port it later. Where this industry is at right now, having two programmers is frivolous, especially when you look at the Mac user base. It's even dumber if you realize you can run the windows version on a Mac with basic knowledge.

Why would you feel sorry for our company? Did you not read my post about screenshots, we get 10 randomly every time minutes so they cant be beaten even if u wanted to, around every minute. It takes screenshots from the second you clock into work, and if you go inactive for over 6 minutes your clocked out... I would say thats even closer monitoring then typical work places. We can view every info from every window they open, including web pages, emails, pretty much any detail. There on strict NDA's and all source code is kept in a virtual env.

Here's the last post by my nephew on the Evolv forum and I think that sums it pretty well.



From what I know from what my nephew told me, remote working is perfectly normal in software development and only amateurs are this .... about wanting to do everything in house.

Very true. Any serious software development company I know uses remote workers. Add the entire F500's to that as well. Sometimes you cant hire someone for technology your using limited so larger companies use remote workers as well.


For all of you to suggest that mac users should have to use visualization to use this mod, you are crazy. Mac's obviously are gaining huge market share, to which most companies now make software cross platform. When you minus bus/edu contracts, the gab because cosumer purchases of mac and windows is much smaller. It does not make sense, from a business stand point, to alienate such a large portion of your market and not even entertain the idea of development. If you think overwise, you need to lay off the koolaid just a little. There is no reason what so ever not to try and develop it.

Here is for you windows fans!!!
1.01 FTW $99!!!!!

FYI... Evolv isn't a software company.

This is completely off topic but now that he works for Red Hat dealing with the source code is much easier for my nephew. The entire Linux kernel is open source and the stuff he works on gets pushed to the main kernel later on anyway. There's nothing to hide.

My governtment just shortened my vaping budget

Looks like I have to wait until august to grab a DNA200. But I will eventually.
