I,m new so please forgive me if I,m asking stupid questions and in wrong place , someone recommended I use homemade atomisers IE 2 screws and some wire and cotton wool which is really not my thing but the question is how do you know what strength (ohms) it’s going to be running at ? And if the answer is you don’t know ,does it matter and would you do it with a high strength liquid. Confused in Thailand lol
Homemade atomiser info needed

Ah, got you @John oakton.
You mean Rebuildable Atomisers.
rda's (Rebuildable Dripping Atomiser), RDTA's (Rebuildable Dripping tank Atomisers) and RTA's (Rebuildable tank Atomisers).
That's the rough 101 on what types are available, but what style vaper are you?
Big clouds or a slight mist?
As we'll be able to come up with some ideas then for you to look at and into.

Slight mist I don’t like big clouds especially as it’s illegal here , but I was asked this before and it set me thinking because I was a cigar smoker you don’t inhale cigar smoke like cigarettes,just take it to the back of the throat and exhale, maybe that’s why I can cope with strong hits , now I’m using 25 mg juice with 0.5 atomiser But what I asked with homemade atomisers , 2 screws and wire how do know what strength ohms it is and what strength liquid would they cope with , for instance I’m finding 25mg is the norm here I have found some 3mg but not often ,
To find out the ohms your coil is giving you need an ohm reader like the coilmaster.
$30.46 Authentic Coil Master 521 Tab (Ohm Meter + Volt Meter) - 0.01-9.99ohm / 0.3-9.99V / USB powered or battery powered at FastTech - Free Shipping
A coil calculator like Coil wrapping | Steam Engine | free vaping calculators might be of help too.

Coil master 521 mini tab is the ohms reader we use.
When you build, you build to the way you want to vape, and you'll want to stay in the .7ohm to 1.6 ohm range, generally speaking. It's trial and error as to where your happy place is.
You'll want to start with 26 gauge kanthal a-1 wire as that's the easiest to work with when your first starting out.

There’s no perfect ohms based on mg/ml, you’ll have to experiment a little to see what suits you best. Is the .5 working alright for you? It’s really a matter of being able to vape enough to satisfy without getting nic sick. And in your case I imagine you want to vape as infrequently as possible.
For what it’s worth, I use 25mg with a .3 coil in pods, when I can only take a hit or two. I use 6mg when I’m able to vape a lot.
What a great answer, the 0.5 works perfect for me.but I don’t want to vape infrequently I vape all the time I have 2 units going all the time just if one fails, and a new still in the box in case one breaks lol Iv also got one set up with a 1.2 coil and trying a mix of a 3mg and 25 mg nic salt averaging 14 but it’s not rocking my boat and if I put 50mg liquid in the 0.5 coil that’s amazing but that does make me feel drunk . I wasn’t trying to find the perfect ratio, nobody seems to understand me about the homemade coil I just thought that if using homemade coil with screws and some cotton wool the strength may be very high so if my 0.5 works for me why not , does that make sense
The nicotine strength you'll receive out of a rebuildable isn't higher - but the flavor notes you'll taste are considerably improved.
When you vape .5 ohm your getting a little too much nicotine, that's why I recommended going as low as .7 for you... it may end up being close to your happy place.. you can vape a little more often usually the higher up you go because the higher the ohm the less the consumption. (Which is why you get a great nicotine hit at .5 ohm and weaker at 1.2)
With your vaping style you'll want to see how .7 ohm is for you as a starting point, and go up incrementally from there if needed.
Resistance depends on:
There are two easy ways to deal with all this:
You'll probably want something like this coil jig to get the right size (ID) coil. Each step on the rod is labelled with a different ID (2 mm, 2.5 mm, 3 mm etc) and you wrap the wire around the appropriate part to get a coil with that ID.
As has been said, rebuildable coils aren't stronger than drop-ins. There are things other than resistance that influence strength, but that's true with drop-ins as well as rebuildables. If they're made with different wire, two different .5 ohm coils can vape very differently - regardless of whether you bought them or made them. Nonetheless, 0.5 - 0.7 ohms is probably where you want to start. If it doesn't suit you, you can adjust the way you make the next coil to get what you want.
- The type of wire you use - the kanthal mentioned above is a good place to start
- The size (diameter) of the wire - This is called the gauge. Higher gauge wire is thinner than lower gauge. 26 gauge kanthal was mentioned above.
- The length of wire in the coil - this depends on the number of wraps in your coil and the size of the coil (or the size of the thing you're wrapping the coil around - this is called ID, which means inside diameter)
There are two easy ways to deal with all this:
- Use the calculator @Territoo linked to - you enter your wire type and gauge, preferred inside diameter and chosen resistance, and it tells you how many wraps you need
- If the calculator looks too overwhelming, ask for help here. People with experience will be glad to suggest specs for a coil that will work well with your RTA/RDA.

I can’t buy a 0.7 coil for my tanks (tornado ex 2 ) and Iv looked at new tanks but the resistance is going down not up ,can you recommend one
I thought you were talking about getting an RTA and building your own coils... ?
We were all here making build suggestions...
No , what I was trying to say was when people make their own how do you know what resistance you’re getting but evidently you buy a gadget that tells you . which I didn’t know , sorry for any confusion
Maybe it's just me, but I never bought one of those gadgets. I just check my ohms with my mod. I also aim for around 1-1.2 and never worry about going too low.
The resistance itself depends on what wire you use as well as what gauge, what the ID (inner diameter) of the coil is, and how many wraps you use.
There's a lot of variants here, so what the end result is just depends.
I used to know off hand what the ranges are for single round wire, but I've been using fancy wire for a while so I can't exactly remember..
But If I remember correctly, using 26 gauge kanthal wire with a 3mm ID about 6 wraps will get you in the .7ohm range, and with a 2.5mm ID you need an extra wrap. 316l SS ohms out a bit lower, and Ni80 even lower than that.
There are calculators for all that, but I've never used them because I'm not doing the whole measuring of the leads thing to figure it out, it's easier to do trial by error because wire is just cheap, and you don't use much to make a coil anyway.
For measuring the end result I use an ohms reader specifically designed for vaping, but like @Shadav said you can also use your mod if it's an accurate one.

This is what I was trying to get to, you don’t worry about going too low , so if I’m using a 0.5 atomiser with a 25mg juice and it hits the spot for me what’s it matter . I apologise again if I’ve upset anybody
In going too low, I'm talking about 0.9 if I was shooting for 1.0. I had it in my mind you were not the clouds type. Most mods should be accurate to +/-0.1. If your target gets to be below 0.5, then yes, I would look into getting a dedicated ohm reader.
*giggles* I'm like, I said what now...though yes that is what I would say
it was @smacuser that said it in this thread *hehehehe*but yes...once you install the coil onto your atty, put your atty onto your device and it should tell you what the ohm is... now whether or not your device is correct I can not say but then again it's the device you will be using so *shrugs*
a lot of people swear by ohm readers, me, meh, I just use my device

Oops... well I will apologize @smacuser for incorrect attribution on that...
Good I had you pegged though @Shadav ! Hahaha
fairly sure I said to you before, don't worry about asking "stupid/silly" questions....because trust me, I've already asked them all....we all start somewhere
I am slightly confused though, are you wanting to make your own coils, or are you just asking how to check pre-made coils?
either way to check them would be the same answer either by using an ohm reader, or using your mod...
but if you are wanting to make your own then you would need a calculator of some sort or to ask someone
it would depend on the wire that you are using and how many wraps and how closely spaced are the wraps to know roughly what the ohms would be...
for instance, back when I was trying to make my own (I forget what the wire I used was, it was very tiny) but it was 5 wraps closely spaced together to get to about 1 ohm
given that any coil built by you or pre-made has a variance of +/- 0.1 (usually more around 0.05)
also keep in mind the device that you will be using it on
some mods will not work if the ohm is below at set number, typically 0.05 but each mod can be different.
and if using a mech mod you really need to know about the battery you are using and it's safety limits. you should still know this on a regulated mod but it's not *as* important as it is for a mech mod where there's not built in precautions to stop a battery from over taxing and venting.
