Why do so many people want to build to 0.1ohm?

Sole people that do can't teach (that's me) other people like him can teach anyone anything about vaping, the fact that I still have hands is proof.
There is the start to tour university right there!!!!
I'll sometimes link noobs to his battery blogs.

Haha word! I had a bit of understanding but his battery blogs were indispensable when I started building coils.

*pours a 40 on the curb*

Glad to hear he's still (sorta) around though!

Lol. Don't even have my clouper mini in hand yet, but researching how to swap in a dna40 board. It's not all hi watts & lo ohms, it's coil temp & efficiency :)

I have a home built dna40 in a Hana box, a couple of rdna40s and a few vsdna40s
They are my all day devices and go to's. I can get all day on one 18650 with that board. And with the temp control its unlike anything else I've used.

-
Because nobody has figured out what power source for 0.001 ohm builds yet?


Is that right?


What do I win?
Hmmm. In my garage now, looking at a 650 watt generator. And on the wall hangs some 4 gauge jumper cables.

Yea, that should work. [emoji12]

Right, Imthatguy....he said he had several rdna40s and a few vs dna40s. As far as I know, all the vs 40s are rDNA

nope.

In an exceptional design feat, the battery has been replaced with a full size 2500 mAh, 35 Amp, LG 18650 hard wired to the DNA 40 board.

You've got a great point mate. Ultimately we all have the freedom to do whatever we want. Nobody can stop another from trying something or even convince them to try it in the first place.

What we should all agree on, at the very least, is that sub-ohm is a reserved practice which should be utilized by experienced hands only. It should not be available to new vapers, period. If somebody new wants to give it a shot, hey that's great! I support that! Now here's about 50 pages worth of homework for you to study.

Crazy as doing .1 ohm build is, I know it's quite possible to do without blowing anything up given the right gear, the right mind, and the right kind of diligence to see it done correctly. I still don't agree that it's a great idea, to each their own. I certainly won't behest someone for seeing their dreams come to fruition.

It's like we need some sort of certification course or Vaper University! I'm serious. You should be able to take a test and check off at least 90% on the following categories:
~Ohm's Law
~What is a short?
~How to be certain your battery has the desired maximum continuous amperage output
~How to make sure your gear stays tip-top, including monitoring your batteries voltage before and after charging, etc

At .1 ohm it's such a risky endeavor, something as simple as voltage drop could spell disaster. Say you accidentally wipe your positive pin against something soft while changing battery or doing maintenance. There was a few specs of dust or a smudge that gets removed. Now your batteries are pulling 84 Amps as opposed to the 42 you're expecting.... we all know what happens next.

I admit that scenario is very improbable but then again so are meteor showers. Those still happen. Our fears and worries are not unfounded in the slightest. If you truly believe you are quite capable of building .1 ohm coil and vaping safely... congratulations!! I applaud your audacity and ability to laugh maniacally at death's face. You're certainly a master of the art if you can pull it off.

But again... do we really want newbie vapers attempting the same? Even someone who can build accurate coils and has a general understanding would be wading into deep waters. There's a possibility here for the situation to escalate if a trend emerges. Perfect storm so to speak. I cannot help but be the voice of reason it's just my nature. Honestly if you want to vape at 100 watts+ just get a 100W+ VW mod. I'll tell that to anyone looking to build below .3 ohms.

So what we really need is education and publicity among fellow vapers concerning the subject and warning new users of the risks. Or a Vaper University. Personally I'm rooting for the latter cause that would be freakin' awesome :D

This isn't about pushing the envelope it's about common sense.

You've got stuff totally backwards in this paragraph.

actually voltage drop sort of saves some people.
example, mod has a resistance of 0.1 ohm, and user puts on a 0.1 ohm coil;
he thinks he's running 160 watts with 4 volts and 40 amps
but he's really running 40 watts with 2 volts and 20 amps
because he's got a voltage drop of 50% (2 volts voltage drop)
and another 40 watts is wasted warming the mod itself.

Then one day they try the same thing with a shiny copper mod with 0.01 ohm voltage drop and it goes BOOM.

What's the difference between an rdna40 and a vs dna40?

The RDNA is replaceable 18650 and magnetic back plate, wireless charging and antad bigger because of that.
The dna40 is a hardwired 18650 and no wireless charging, its about the same size as the vsdna30 with a skin.
Imho its the perfect form factor, with a erlkonigin nano it fits in a shirt pocket .

I know that but thanks for pointing it out. For it to be an accurate postulation I was assuming someone built their coil for a battery which they have currently charged below 4.2v. Yes that's totally stupid thing to do, assuming your max voltage is say 4.0v and building your coil around those parameters. But that's exactly the type of harmless user error I was trying to epitomize.

Even so, it seems well said that measuring resistance at those levels without highly sophisticated gadgetry is not going to work in your favor. Give me enough time and I'll think more likely situations.

From left to right
Dna30, dna40, rdna40
I have the 20, 30, rdna30 and rdna 40 but my rdna40 has the big screen. I wonder if they'll offer the dna40 with the big screen. I love their stuff and as far as I know, thats the cheapest dna40 (evolv) out there. $159???? It's a steal. Thanks for the info!
