Yes, it can be overwhelming, lol... To make it easy, just select a gauge of wire. For an RDA like the Plume, I'd go with 28ga for simplicity. It is thick enough to work with, and still thin enough to allow you to have room for error in your wraps. When you use the calculator, plugging in the known value of 28ga, and using a known size drill bit to wrap on are easy enough to plug in. Then select the desired Ohms you want to hit... which for your DNA20 must be above 1.0... so select 1.2 Ohms for a nice round number.

For this coil, you would make 8 wraps around a 2mm drill bit (both legs/leads facing the same side). This will give you a 1.2 Ohm single-coil. If you wanted a dual-coil build, you would make two identical coils, 16 wraps (each) around the same 2mm drill bit. All of this came from the online calculator, and it is for reference... the only way to be sure of the coil you built is to use an Ohm meter!

You still need an Ohm meter to verify you did it correctly, and that you don't have any shorts before attempting to fire it. Once you confirm it is built correctly, wick it with the wick of your choice, add juice, and vape!

Again, the reason you're getting "check atomizer" is not because it is necessarily "unsafe", but because the resistance of the coil your attempting to use is below the capability of the device. The DNA20 will not fire any coil below 1.0 Ohms, and may even be picky about those in the 1.1 Ohm range... which is why I suggested a 1.2 Ohm build... and you can go higher, if you add wraps to the coil.

A thicker gauge wire will take more wraps to make the same resistance. A thinner gauge wire (like 32ga) will take less wraps to make the same 1.2 Ohms.

Hello everyone! This is my first post and I hope to make it worthwhile! I am not sure if this is the type of forum where you are expected to search through previous post to find answers. If so I apologize, I would prefer to explain my individual situation and get some advice.

I am attempting to build my first RDA, having some issues, and that is where you guys come in. I'll begin by telling you the equipment I am using prior to adding a rebuild.

1. DNA 20 Clone
2. Aspire Nautilus Tank

I have recently decided I would like to try an RDA because the idea of dripping appeals to me. In addition, even though I have a 20 watt battery, the Aspire tank seems incapable of handling anything over 13 watts, anything over that is extremely hot and often harsh as though I am damaging the coil. I'd also like to be able to switch or sample flavors without switching tanks.


I am aware that a DNA 20 is probably not the best choice for a rebuild as it is quite weak. I am not interested in buying a new battery until I at least get a working rebuild and decide for myself if it is sufficient.


Anyway there is the background, on to the rebuild.

I purchased a plume veil clone recently at a local vapor store. Unfortunately the person who knows rebuilds was not there, and after much pressuring the girl told me she would do her best to set me up. (She didn't think she knew enough to help me, she was right).

She gave me a 28 gauge "pre-built" coil. I was okay with the prebuilt because I could see how a finished product is supposed to look, I don't remember how she came up with 28 gauge.

I came home and hooked it up correctly I know after watching many videos. My DNA displays "Check Atomizer". I have tried taking out battery, lowering wattage even to 7 and up to 20, and nothing. I do not have a tester so I don't know the resistance although I am thinking due to the size of the wire it is too low for the DNA.

So my question is this.

1. What do I need to do to get my RDA working on my DNA clone, other than buying a new battery.
2. What gauge wire would be best?
3. How many wraps? (I guess this depends on the size of the object I'm wrapping but still)
4. What type of cotton?

I appreciate any help I can get, sorry if this is not enough information!

Welcome...

First of all... the reason your MOD is reading "check atomizer" is because the coil she gave you is below 1 Ohm (sub-ohm), and your DNA20 will not fire any coil below 1 Ohm.

We're all for helping, and guiding you along, but first thing is first... you need to get a proper, dedicated Ohm Meter for checking your builds BEFORE you attempt to fire them with any mod... catastrophic "booms" can and will occur with improper equipment and super-low Ohm builds! Safety First!

The only way to get your DNA20 to fire the Plume Veil is to build the coil above 1.0 Ohms.

The type of wire and thickness is up to you... Kanthal A-1 in 30ga, 28ga, 26ga will be perfectly fine (and up to you)

How many wraps? Use an online calculator like Steam-Engine.org to determine coil builds... and LEARN Ohm's Law (again, Safety!)

Cotton will be your choice... Silica wick, Standard Cotton, Organic Cotton, Japanese Cotton, Rayon... all useable... Organic cotton, Rayon, and Silica are easiest to work with (don't require boiling or prep-work).

Watch LOTS of youtube videos, buy an Ohm Meter, and buy a MOD (and battery) that are safe for sub-ohming . There are hundreds of threads on here with TONS of info on builds, batteries, MODs, cotton, and how-to's... you don't have to read them, but it is honestly easier to skim a few dozen posts than it is for you to wait for 50 people to comment on this post
