“which I believe is 0.08 ohms” – this is alluding to the fact that I may not know the exact answer. I do not build into the super sub ohm or however it is referred to, so the lower limit of a dna board is of no real concern of mine. Regardless of what ever the limit is, or Busardo’s knowledge of said limit, it does not change the fact you are working with a massive coil which is what this discussion is about.

I am not trying to get you to build anything. You opened the discussion to which I am just giving an opinion.

coils coils coils! I love it! Lol

Here's one of my rules for builds, whenever possible I don't wind coils longer than 1.75 times the ID. Doesn't matter what atty or wire, claptoned or not. Longer coils have too many shortcomings....errr uhhh, you know what I mean. Its too difficult for hottest part of a long coil to stay saturated, even with rayon. Some peeps swear by them but I've converted more than a few of them to shorter coils.

The Steamcrave Plus is a 30mm tank. That is HUGE! And I don't see how one could avoid to not use a use huge coil(s) in a Plus. Why? Do you think smaller is better in a 30mm tank?

The Air holes aren't that big. If you exceed the air flow hole with the coil, it don't get air on the whole coil. The postless deck is huge, & can accommodate a big coil in diameter, not length

I didn't have time to post these before work last night so here goes. I most of the time make the same coil for all my RTA's so I know what kind of wattage to expect from them....with similar air. I vape wattage just as before TC but now keep that over head protection of TC for those "special occasions" On a new build if it hits temp and throttles down I'm back into the build to find out why. The first screen is when I just tried my new build on my Skyline styled, the 2nd it after I went back in a couple of times to trim the tails. I'm not that experienced with the Skyline build so I don't maybe get it first try. Twisted 2 strand 28 gauge Unkamen's SS430....what else.

There is a 3rd screen that I did just a few minutes ago and it resembles the 2nd screen so I'll not post it.

No denying the Steamcrave is a big tank. But how big is the deck and air chamber in comparison to a regular 24mm RDA? I don’t own one so going off what I see on the internet. Regardless, the size of the deck and or air chamber does not bend the laws of physics in relation to coils where more mass equals longer ramp up time.

If looking to capitalize on surface area with larger coils then one must choose the type of coil wisely otherwise suffer from long ramp up. You want a large Clapton, then pick something with a higher gauge wrap (thinner) that does not influence the mass and resistance as much as a coil with a lower gauge wrap (thicker).

Example. One of my preferred coils is a N80 fused Clapton consisting of 4x 30awg cores and a 40awg wrap. 4x 30 awg is the equivalent to a single 24 gauge wire. However, given there are 4 of them they can be positioned in such a way that there is more surface area in comparison. So ~50% more surface area with the close to the same resistance and Heat Capacity. And the 40awg wrap has a minimal effect of both mass and resistance.

There is always a compromise. Our challenge is trying to find a happy medium.

As you may already know, I prefer the first graph....

This is more important in a Mec! I use a similar Nichrome coil in my mec's.
For that very reason, when you're limited to 4.2 volts, ramp up is more of a concern.
With DNA250's this is less of an issue, the preheat can be set for power & duration, ramp up time can be controlled/eliminated! I ramp up my big Ti Claptons all most instantly with 100 watt preheat

 

[cigatron]

What kind of gear are vaping on Punkster? Oh yeah, welcome to the thread.

 

[Punk In Drublic]

@Steamer861 - I agree this is less of an issue with a regulated device in comparison to a mech but can still be an issue non the less. And yes, we are discussing this within an Evolv topic where DNA’s boards excel at TC. But not everyone uses TC therefore one has to be selective on the type of coil they use should they want to capitalize on surface area.

@cigatron – Thanks! Given this is a evolv thread guess it would not be fair for me to jump in with a Yihi…LOL! Joking. I own 2 Triade’s and a Paranormal. Also few other non DNA devices. Preferred RDA (at the moment) is the Profile mesh which I have a few setup with both Kanthal and SS mesh strips.

My Ni200 builds come in right around .028, the only DNA boards that don't like to fire that low in TC that "I" have tried are the 60 and 40. The 60 will fight it and try to fire, I can get it to work by heating the coil enough to get around .031 -.032 and trick it but what's the point? The 40 just rejects it. But the rest of them, 75, 200, 250 and C's work fine.

Welcome fellow Canucker. Whitby here

Given this is a evolv thread

And coffee. Don't ever forget the coffee. Many of the finest brewed by Tibs, and gnees. DW likes the redder blends. Mike posts lighter blends, almost decaf, yet still great. classwife ensures the beans are well ripened, aged, and presented properly. The rest are just here for our good looks.

I own 2 Triade’s

2, eh. BillW50 will like you.

Ya I took a guess at the lower limit of a DNA board and based that comment on my assumption of a 0.08 ohms limit. Thought I read somewhere that 0.08 was the limit…..could have been a different board or the comment came from someone who doesn’t know (like me!!). Non the less, that Clapton wire is massive which did prove to be too much for another device to handle. And by trying to mitigate the Heat Capacity by reducing mass, you do lower the resistance.

@Wayneo - Thanks! Lurked for a while strictly for the coffee

 

[ShamrockPat]

I think it's actually .02 on the 250C or so I've read so it won't fire metal shavings and paperclips.

Evolving yes in that was what it started from, well actually this thread was a place for us to keep having all the great fun we had in Mike's co-op's. Mike keep those so much fun, I really hated to see the threads have to close so this thread became a place to hang and chat about anything but center around the main stay of Evolv related products, mod building and morning coffee!

Looking back we've chatted about just any topic here at one time or another LoL, it's got to be one of the longest threads on any forum I've hung with.

Yes – I looked it up after responding to SlickWilly. Although Evolv doesn’t mention anything about metal shavings and paperclips, they do state 0.02 is the limit. Thanks

Mike posts the decaf He's going to like that!

Whoa! Have you two looked at what is out there? The largest atomizer I own with the largest airflow are my two FreeMax Mesh Pro tanks. And looking down the bore between the FreeMax and the SC Plus, the Plus is larger! Although opening both AFC to max and doing a pull on each, it is neck to neck. Virtually identical airflow!

Now looking down the bore of the FreeMax and their build is massive! Much larger than anything else I own. Now I look down the bore of the Plus looking at my 3mmID Clapton 11 wrap coil, and it looks so tiny in comparison. If anything, my build isn't large enough by far. Heck even my Crown tanks doesn't even have anywhere the airflow of the Plus. Yet they even use much larger coils than my build.
