My thoughts about sub-ohm and latest VV/VW devices...

[MattB101]

They make perfect sense to me, in a "yay I can leave the house with one extra battery instead of a pocketful" sort of way. Yes, not everyone agrees with me. Maybe I'll just not be lazy and build one myself. I'd rather buy one that didn't look like it was assembled by demented monkeys, though. As an example, I have to carry two 18650 spares if I leave the house with my ProVari for the day, and the number goes way up if I grab the Stingray X instead. With my 26650 mod I bring a spare. Just one. That's why I'm curious about the battery life the testers got.

I built myself a box mod using the SX350 chip and parallel 18650 VTC4 batteries. I can vape it all day using a 1.4 ohm build at 14.5 watts in my Kayfun Lite. Love it. Battery at 4.2 volts in the morning and approx 3.5 volt at bedtime. I use the USB charger that came with plugged in to a 2 amp USB wall wart charger at night and it's fully charged in about 4 hours. Bought the chip from A to Z Vaping as a kit. Vaping about 15ml a day I think.

Sent from my Galaxy Note 2 Android phone on a keyboard that waaayyy too small (or my thumbs are waaayyy too big).

So risirius, I'm not personally attacking you but most of your ideas and concepts sound exactly like the ideas and concepts from Evolv's DNA 40 research? It sure matches up pretty well and your timing is uncanny. Do you also claim like Evolv does that one can perhaps avoid certain undesired vape chemicals by not over boiling juices? Just curious.

 

[WharfRat1976]

I think one of the major points of the DNA40 is that resistance doesn't matter if Ni200 wire is used for a coil. Power will be properly controlled by the chipset to prevent any problems (assuming everything in the chipset is working properly) so the hazards of sub ohm producing fatal overloads will be eliminated. Given the fairly large number of people who are vaping at very low resistance levels without a problem on "normal" devices, controlling the temperature is like getting a good insurance policy.

Yes. The DNA 40 REQUIRES Nickel 200 Alloy which is made of pure nickel. It is billed as non- resistance wire.

 

[Katya]

Never mind--wrong thread...

 

[Rossum]

Yes. The DNA 40 REQUIRES Nickel 200 Alloy which is made of pure nickel.

Uhm, no, it doesn't. It will run as a normal VW regulator (without temperature control) with conventional nichrome or Kanthal coils. Ni200 is only required if you want to use the temperature control feature.

Yes. The DNA 40 REQUIRES Nickel 200 Alloy which is made of pure nickel. It is billed as non- resistance wire.

Well, not exactly pure Ni, then it wouldn't be an alloy. I think it's +99% Ni.

imsoenthused, my comment was meant in a humorous way. I hope you weren't really offended. My own liquid consumption seems to be ramping up from 8ml or so a day to about 15ml a day since I have discovered RTAs, all that vapor has to come from somewhere!

My response was meant to be humorous as well, no offense taken or intended.

 

[WharfRat1976]

Does anyone know the temperature created on a coil at low ohms...say .8 to .15? If it is well beyond boiling point for vg I'm done with that...assume 4.2 volts on it...I mean I like the blackened crispies on my brisket pieces but they don't go into my throat and lungs...

Unless I completely misunderstand your post WharfRat, I think you should re-read the OP because I think you don't get it.

IMO the OP was mostly about debunking this myth and included the science behind it all; "That's crap man... You can't get thick vapor on anything that's not sub-ohm dude...".

The DNA40's claim to fame is temperature control. The chip actually only runs Ni wire at 0.1 - 1.0 ohms. Yes, it maxes out at 9V I think, but I also think you will not see that high voltage at 1.0 ohm and 40 watts but rather with Kanthal which it handles to 2.0 ohms.

Hope I didn't totally miss your point and that I'm making some sense here

I don't think anybody ran any tests to determine that--maybe Brandon and Jon did.

The bottom line: any atomizer is just a heating element that is cooled by e-liquid. Which means that no matter how hot the coil gets (within reason, of course), once it gets hit with cool liquid, its temperature will drop and the said e-liquid will be instantly turned into vapor at the precise its boiling (flash) point. The hotter the coil, the faster the evaporation will occur. So, provided you can keep the coil wet at all times, nothing will crisp. Of course, the hotter the coil, the more e-liquid you have to be able to supply to it--fast. If the coil gets no eliquid in time, it will turn red hot and crisp anything it comes in contact with.

This issue has been debated here for years because we were worried about acrolein formation with VG-based e-liquids. If you want to learn more about it, this post is very informative:

Right... I didn't want to say anything, but... yeah. I hope we both misunderstood the poster's allegations. Or the poster misunderstood the OP.

Or maybe I'm missing something.

Glad you pointed that out Ryedan, hmm so with the Temp control and Ni1200 we're going to be running sub ohms coils only (other than 1 ohms) ?
Interesting.


Is that why we're talking about 32g wire to get more wraps in for surface coverage?
or wait... let me think about that.

 

[rhelton]

I dont really know what the truth is or facts about this new board. What I do know is what was presented in the Busardo video was someone is testing juice being vaporized at different temps, the results will come from a lab and presented to the FDA. With those findings there will be regulation of vaping as we know it.

And guess what, Evolv has the patent and the device to smoooch over the FDA and we all be stuck using their products in one way or another. Whether its their board, or someone else pays royalty's to use their technology in their own device.

It wont affect all of us, as some of us mod, or know someone who does. But you know I didnt like what was said and the way it was presented. And I know I dont have to buy one if I dont like it.

Say what???? So Mitch Zeller and Brandon are in it together? Is Dr. Farsalinos also a part of this kabal? How about Kanger and Innokin--are they getting a cut, too?

Do you have any inside information about Imeo and his new device? It's also temperature controlled. It's called VIR.

Seriously rhelton....

But I do agree with two things you said in your post:

1) You "dont really know what the truth is or facts about this new board."
2) You don't have to buy it.

Peace.

op is about vaping to the opposite of sub ohming. Debunking the myth of resistance matters.

Just said OP is espousing the exact same theory behind Evolv's DNA 40 chip and why they created it...

 

[ukeman]

Yes, and someone ( i think dr g) said thick wire (26g) would be more difficult on a DNA 40... I'll have to go find that; theres a few thread now about dna40.

I'm trying to figure how to wrap a 30 to 32g Ni200 coil at .16 (to .4 to .9) Ohms and get lots of surface area... which is part of the OP.

We've moved on from the OP to dna40 here... ?

Yes on the sub-ohm coils ukeman. However I think we need to forget some of what we know about how sub-ohm coils behave in general because of the addition of temperature control in this system. I don't know much about it and have not used it myself, but from what has been said so far it works very well. It makes sense to me as far as I understand it, but it's very early times still

Same goes for thinner wire. I know that using thicker wire for a given resistance gives me more coil surface area and mass, but again the behavior of this system using temperature control is I think going to be different than what happens in my mech mod.

For sure, sub-ohm coils do not imply a high power vape or cloud chasing once temperature control is in the picture.

 

[Katya]

Just said OP is espousing the exact same theory behind Evolv's DNA 40 chip and why they created it...

Well, not really. Not to my understanding.

The main point of the OP was that you don't need to go sub-ohm to get plenty of clouds. Which most of us here are very well aware of, BTW. And have been for quite a while. That's why so many of us like double-coil (and even quadruple-coil) atties--more surface area, higher resistance of each coil, higher voltage = more clouds.

With higher voltages you can build higher resistance builds with much more surface area and good heat flux to produce massive amounts of vapor with absolute consistency. And that my friends is exactly where these high voltage regulated mods shine.

The revelation (to me, anyway) of the DNA 40 chip is the concept of uncoupling of power (wattage, volume) and temperature (flavor, safety). You can keep your high wattage (clouds) and lower the temperature at the same time to a safe or simply preferable level. That is a completely new phenomenon. High wattage vaping will not require high temperatures any more--no more burning and scorching and, potentially dangerous, chemicals being formed in the proces . The OP didn't mention that at all...

If I'm dead wrong, somebody please shoot me. It's late.
