I love vaping at high watts, I love the clouds and a love warm flavor I usually vape from 70 to 100 watts with .2 to .4 ohms of resistance on 26 gauge kanthal. but ever since this Xmas all i've been hearing is temp control mods using the dna 40 chip. I love the idea of no dry hits! i just wanna know if i'm going to get the same clouds or will their be some cut backs. Also has anyone done the efficiency calculation on the dna 40. i heard around around 95%. :vapor:

Temperature control is still in its infancy. Despite many folks around here promoting it as "more important than VW", it still has it's issues.

However, you should realize that temperature control (as done by the DNA40) is a LIMIT. Doesn't mean you vape at that temperature, just that you won't vape ABOVE that temperature (assuming a bunch of things, by the way).

Don't get me wrong, temperature measurement and control could be a great thing. But as it exists nowadays, the actual temperature is just an approximation, and I believe that your taste buds are much better at detecting when you're in "dry-hit" territory than the DNA40 is.

And nickel wire blows. Titanium is a bit better.

I bought some (intended for jewelry-making) from e-bay, and then got a big spool of it (also from e-bay). Don't know of a good regular-store supplier. Be careful, though, some "titanium" wire is titanium colored (and is actually plastic-coated copper!) so read the description carefully!

At room temperature, titanium is much more conductive than nichrome, by about a factor of 2.5. This is a bit misleading, though, as it has a relatively high temperature coefficient; at normal vaping temps it's probably more like a factor of 2 or less. The wire I have is 30-gauge.

I'm with twgbonehead, I prefer titanium at this point. You can find the Grade 1 on Etsy. I get it from Ralph and he can get you larger spools if you are interested. I'm using mostly 28 and 28 gauge these days. And the DNA40 while it produces a nice vape can be a PITA. You need a good RDA or RTA, great contact points, the wire needs to be solid under your screws and clean 510 connections (real clean). If there is a weak spot in your build the DNA40 will find it. Personally I think it's a very unforgiving chip but that's just my opinion.

It's nice for the enthusiasts, someone that has been building a while but can easily become frustrating if you don't like to experiment and play until you find your sweet spot.

Titatium Grade 1 Etsy

The Ring lord is also a good source but use the contact form if you want larger rolls

28ga Titanium

And the 24ga grade 1 is fairly easy to find on eBay.

I ordered a Hana Modz, and it comes in Tuesday. I've been building spaced out single coils, practicing for nickel wire. I haven't been Using my Doge V2 because the last one i had i melted it, so i hoping it would be better on a Dna 40 Regulated device. My titanium wire is still in the mail, and ill be using it as soon as its in on my ivp2, i really want to get another Kennedy, flavor chasing seems to be more my thing these days, how are hot spots (shorts) on the titanium wire?

personaully i am loving my hana dna temp control. I can build kanthal coils good and the nickel my me is easyier to make good coils other people say it is harder for me i thought ow great but is softer and better to use for me taste better then kanthal i have never used any wire besides kanthal so cannot compare to others i use 28 gauge kanthal is what i like and the nickel taste better then that. i am not a sub ohm guy usually build kanthal aroun .80-1.0 ohm is what i like and build these nickels at .12-.16 it is very hard for me to use any other device now. just ordered another vd4 last nigh and own the b4s now which is the single battery brass edition

I love my DNA 40 and even though temperature control is a new thing, I'm enjoying the vape much better then my higher wattage iPV.

And keep in mind that nobody should be vaping above 536 degrees Fahrenheit anyway because VG becomes toxic at this temperature and turns into acrolein. I'm keeping mine at 500 to 510 degrees to be safe. 40 watts brings you to this temperature pretty darn fast.

I'm holding off on temp control until they have one that works with kanthal or nichrom. Its all just metal, it shouldn't be too hard to do or too long before we see it.

But that's the thing, though, it's not "all just metal." Nickel is special, in that its resistance changes a great deal, and in a very predictable manner, as the metal heats up. A nickel coil, at room temperature, has a notably different resistance than that same coil at 250F, or at 420F. That's how the device "measures" the temperature; it reads the resistance at room temperature (and it must be at room temperature when you attach it, or it won't work correctly since the calibration will be very far off) and then by measuring how the resistance changes as you apply power, it can determine the average temperature at the coil. Kanthal doesn't do this. A kanthal coil has basically the same resistance at room temperature as it does at 500 degrees. There's no change in resistance, and so there's nothing for the device to measure. How can it limit the temperature if it can't figure out what that temperature is?

Not saying it couldn't be done somehow, but the resistance of Ni200 changes in a predictable, almost linear, and easily measurable way as it heats up; not so with Kanthal or Nichrome.

I was kind of hoping to see some information from an actual professional and not some guy with an extremely unhealthy diet, YouTubing from his room in his parents house. Some of the comments to that video are saying otherwise as well.

A quick web search will also speak of dangers in everything we use for vaping.

Is that the Navy blue? I currently have a Phantom Black and my Navy Blue comes in Wednesday. Looks darker than the site.

WELCOME TO ECF OP!
