I'm glad your happy with your setup Jimi, who cares what's going with the ohms thing, I was surprised as I got my method down how the resistance stayed up instead of dropping all the time due to shorts. Just looking out for you as I've had higher than expected ohms on one of my DIDs due to a poor ground when I used a smokteck shorty plastic tank and it was a tad longer than the standard ss tank and the thing needed to be super tightened on the Did to get a good connection, and a slightly loose terminal screw has also been the cause of higher than expected Ohms. I've been known to be too helpful LOL.
You are a very helpful gentleman indeed. I hope it's not a grounding problem on my DID and Provari.

faith my friend......hope and trust in in the vaping scientists :)

Don't get me wrong emonty, I was excited, but the power efficiency and airflow factors will take some over comming IMHO.
I will be keeping my eyes on the thread though as it's full of promise, and all the brainstorming will undoubtedly lead to somthing juicy.

No problem Jimi. If you want to check the true ohms of you setup and have an accurate voltmeter In resistance mode ( check the the leads have no resistance when you short them together, if they do have a resistance you will need to subtract this from your reading) then you can put on lead contact on the negative screw/wire clamp and the other on the positive top nut and that should give you a starting point. If that reads the same as the Provari you should be all good :)

This isn't really 500 mesh specific, but the most recent posts have been about the resistance of particular coils so I'm hoping my favorite genesis people here in this thread don't mind giving their usual educated insight.

Twisted coils on genesis devices: I understand that they cut the resistance compared to a single coil of the same wire, and the common rule of thumb suggests it's just like a dual coil. So, if length A of wire B gives you C ohms, then (length A of wire B) x 2 in parallel gives you 1/2C ohms. But is this really how twisted or braided coils work? From an electrical perspective does the circuit not "care" that the wires are touching or do you end up with less than 1/2C because they are touching? (Something I have also seen suggested.) Is it neither of those two things?

I'm very curious about the technical explanation of that, but I am also interested in the claim that twisted coils don't short as easily. Similarly, I've heard people suggest they don't short as easily, and then go on to say that they don't pop as easily when they short since there is more wire; those are 2 different things.

I hope that makes sense. I sometimes leave out steps in thought when I let my internal discourse out into the wild... Anyway, I guess this is a post that's in the myth busting spirit of this thread more than the 500 mesh part; I just knew I wanted to post it some place where I'd get more intelligible answers than, "I use twisted 32 on my XXXX atty and it vapes like a mack truck LOL".

Both = 1/2C. it does not matter if they are just parallel or twisted together. The old water pipe theory, the larger the pipe the less the resistance.

Thanks, BJ. That was my initial thought, but then I started thinking about it too much lol.

Do you have any opinion/experience regarding the difference in the likelihood of, say, a single 34g coil shorting to the wick vs a twisted 34g coil shorting to the wick? My initial thought there was the the resistance of each wire at any given 1mm section is going to be the same so a twisted coil will be just as likely to short as a single wire coil.

Just put together a 500 wick for the DID. I have to say I find it really easy to roll, 100 mm with a tiny pin hole was a joke. Either I'm more forceful than I think I am or someone at the mesh company is taking a piss lol
LOL That's all you rolled !? I expected more length from a dude that blows away Billy Sheehan out of the water. :)

I wish bro, I'm just a wannkir riding airplane after airplane right now lol

I was testing the theory that too much is no good. Testing, as if I have the time to compare anything. Bottom line these days is I need a certain plasma level of nicotine and I'm gonna get it in one way or another.

Personally think more contact of the wire on the coil the better, twisting tends to lift part of the wire away from the coil. Can't really see that twisting will short, but if part of the wire is drier it can hotspot.. Not all hotspots are shorts.

I have to remember that I drilled a hole in my fill screw. I've had no wicking problems with my DID. Just shorts LOL When you get back, you should give it a try. :)

Yeah, I think that all makes sense. It's not really an issue for me at the moment since, thanks to previous orders and kwalka/rusalka, I've got 28, 30, 32, and 34 awg wire around :toast: I can't think of any good reason to try twisting resistance wire as long as I've got that selection. I was just discussing the issue with somebody who was stuck with only 34 for several days and was looking for ways to have a more stable/usable coil, and he brought up the idea of twisting the 34.

Is anyone having any joy with running a truly efficient genesis setup (battery consumption wise) with the #500,
I have been using semi solid wicks for a while now and I just cream my batteries in no time, admittedly I am running 0.7-0.9 coils on my Paps, but I have 10 gensis attys four DIDs 3 AGAs 3 Chi Clones, and I'd like to set a few up for longer battery life without sacrificing to much oomph!!
Is anyone still using a wick with a center channel, or doing really tightly grouped coils right in front of the airhole. Or using 38g Kanthal or......... ???!!!!!.
The challenge is best flavor and vapor for real world vaping (i.e some tilting but no drinking) with least watts.
Watt you got guys?
