Hey guys, new member here witha question or two!!

[TrevSpitz]

Hello all, my name is Trevor. I'm new to this forum obviously but have been vaping for about two months. I currently use an MVP 2.0 with whatever clearomizer came with it and am interested in getting into rda's and stuff. And to start my first post I have a question.

So the other day I bought my first rda, I believe it was a Mutant X clone. So I built my first dual-coil build ever on it using 24 gauge kanthal and i did around 7 or 8 wraps around a 2.4mm screwdriver. And i also did another dual-coil build on the same screwdriver using 24 gauge kanthal but this time i did around 11 wraps i think. So i popped it on my mvp, not expecting it to work, but i just wanted to calculate the ohms cause apparently the mvp has a built in ohm calculator(I never knew that). And so i pop on the 11/12 wrap build and it measured at 0.6 ohms. I thought that was wrong because it was my first build and i really wasn't trying to sub-ohm. Then when i popped on the 7/8 wrap build and tested it, it read as 0.0 ohms. So i guess my question is, did i do something wrong with the 78 wrap build? Did i not do something right? Or did i accidently build something that it below 0.1 ohms? Thanks for answering this in advance!

Also, what would be a good set up if i wanted to get around 1.2-1.6 ohms? And by set-up i mean like, what gauge of wire should i use and how many wraps?

Thanks for all the help guys!

yes get yourself some 28 ga and a coil build calculator. steam enginefor pc or vapers tool box for android are a couple good ones.
You need to learn ohms law. Not negotiable.

This kind of stuff is too advanced for the simple solutions section, just a warning it'll get moved =p

Of note is that the MVP2 is rather limited in what power it applies. I believe it is only 6-11 watts. The PSuardo review indicates that it has trouble providing a smooth output below 1.5 ohms of resistance.

That said, I like mine. I use 2.0-2.5 ohms of resistance coils in my Protank/Naultiluses. I just see it as having limitations towards lower ohm settings. The literature says that it will fire a 1.0 ohm coil, though.

They (2) are back-ups and will probably get passed on eventually.

Hope helps.

i would've posted it somewhere else. But since I'm new I can only post in the new member section or whatever

I'm not sure if the MVP would give an accurate ohms reading when you're below its vaping threshold, I'd recommend either using a multimeter or dedicated ohm meter in that case. If it IS accurate and you're getting 0.0 then it's possible your build has a short

24 gauge is definitely a bit too much if you're shooting for 1.2-1.6 ohms, that would be a lot of wraps. 28 or 30 might serve you better for that resistance range . . . either 30 or 32 gauge if you're doing dual coils at that resistance (doing dual coils will give you a total resistance of HALF the resistance of one of the coils. ie - a dual coil with 2 coils at 2.0 ohms each will give a total resistance of 1.0 ohms)

 

[rodeo302]

I'd say 24 gauge is for more experienced builders try out 28 gauge or 26 at the biggest to start with and go single coil for a while until you got the wrapping down.

 

[TrevSpitz]

Yeah that's true. Because one problem I'm having is that when i tighten each screw in the negative and positive posts, often time the wire just snaps and then i have to start over. Am i tightening the screws too much? Its getting really annoying and happens more than i think it should (almost every time i try to build, i end up having to build a third coil)

File a very SMALL amount off the bottom of each screw or don't tighten it so hard. 30 will heat up much fater. torch it first it is a little easier to work with.

Great idea. Some of the screws in attys will have burrs that will cut your wire. Some sandpaper should work too if that's all you have.

You already got a couple of good links for calculating the resistance of your builds. I'll just add that you might want to start with a single coil, get it metered and mounted, wicked well and have a vape.

You'll learn a lot adjusting the coil and wicking as well as the air flow over the coil that will be invaluable when you are trying to trouble-shoot more complicated builds.

I started with a simple 1.5ohm micro coil (touching wrap, 1/16 drill bit, 30 gauge, 8 wraps) and learned how just a simple adjustment of moving the coil a fraction up from the deck or a fraction away from the airflow makes a big difference in vapor and flavor.

It's worth the investment of time in my opinion so you can get those dual (triple, quad, whatever you want) dialed in and perfected.

Nothing more to say except welcome to ECF, make yourself right at home

I hope this isn't a stupid question. But it won't hurt my RDA to only have a single coil in there to start out with? And also, what is a parallel coil? I don't plan on building one any time soon, because i dont know what they are really and what they do, but I'm just curious. Thank you guys so much for the help you're giving me.

 

[ElConquistador]

No, won't hurt your rda to run a single coil. You might want to somehow block off the unused air hole temporarily. I *think* a parallel coil is a dual built out of single strand of wire? Not sure why that would differ from a dual since it's all connected at the post anyway, but someone who knows can explain it.

 

[DreamWithin]

No such thing as a stupid question You'll be perfectly fine with building a single coil. I'd actually recommend going that route if you're just getting started at building coils

Parallel coil is just another way of saying dual coil, really. When you build a dual coil, the coils form a parallel circuit as both coils will have the same positive and negative end points
Here's some not-so-light reading on series vs parallel circuits: What are "series" and "parallel" circuits? : Series And Parallel Circuits - Electronics Textbook Just in case you're curious and want to understand the concept better

Sounds like the second one has a short. Make sure the coils aren't touching the posts or deck. I started with 24g but went to 28g. Here is a coil calculator that might help you out.

 

[GrumpyClouds]

I would use Steam Engine like eyerhere suggested, but maybe something like 28 ga single coil 10 or 12 wraps around like a 3/32" drill bit...should read around 1.2 ohms... go ahead and build single...putting a 2nd identical coil on should cut resistance in half. also, a parallel coil means you take 2 strands and do half the wraps. they are more difficult, but they help lower resistance for some sub-ohm builds...i use between 20 ga and 28 ga wire (usually kanthal, but sometimes g plat).

Message me with any questions!

Cheers!,

Hey guys I'm back with another question or two. So today i went black Friday shopping and got a manhattan clone by Tobeco, and in the process i won a kanger aerotank turbo, how cool!! So my question is, I've seen reviews of the manhattan where it comes with extra pins and i was wondering why mine didn't have that? It looks just like the others on YouTube, but when i look inside is a little different. Any explanation for that would be greatly appreciated.

Second question: I've watched a lot of reviews about the kanger aerotank turbo and seen that it won't work on a vape that isn't running at a high enough wattage. So my second question is, if I'm using this manhattan clone and an 18650 battery, is it gonna be putting out enough power to run it? Thank you guys so much for help with this as well. I can't express enough how much i appreciate it!

EDIT:
I guess i have a third question as well, when the put the kanger turbo on my MVP to test the ohm, it shows up as "NON" which I'm pretty sure means tgat it isnt reading that a tank is on there. Is something wrong with my tank? My mvp? I just wanna know if I'm doing something wrong haha. Thanks again guys!
