Iv seen lots of videos of people with dual coils on their rba producing a TON of vapour!! But they are all at very low ohm's on a mod.

I have a Vamo so i am limited to ohm's. Without buying a mod has anyone achieved this sort of vapour production?

I just recoiled my Octopus using .20 kanthal wire, 5 2inch lengths of silica wick(1mm thick) and eight wraps. Im not really getting a hell of a lot of vapour production. I have also tried the same thing with 3mm wick but less wraps with .30mm wick but that was worse!

I tried the dual coil set up and the bunny last night but the ohm's was to low for it to work. I also added another hole to the case but still no difference.

Any suggestions or ideas?

Thank you in advance.

Keep one thing in perspective as well....you're watching people on a video...

Lighting, video quality, etc..plays a big part of that. Once I thought I wasn't getting big clouds so I used my iphone to watch myself and BAM the cloud I exhaled looked like A Bomb!!!

Sometimes you have to focus on if your feeling satisfied not how much vapor you're exhaling.

Just my 2cents :)

Saw a good piece of advice on here a few days ago.
Don't worry about vapour production, close your eyes and vape. If you feel satisfied you don't need massive vape clouds.
Also on a lot of vids they take long slow drags without inhaling and blow out through the mouth or nose during the draw, this helps to give the impression of massive clouds. I can do this with my Vmod and fill the room with vapour, but it doesn't satisfy any more than a normal draw on a 650 ego - but does use up more juice :D

It won't do you much good to count wraps or compute mm thickness without a multimeter.

What was the ohm rating of the coil you wound? For example: two 3.1 ohm coils will be 1.55 ohms and 3.23 amps at 5 volts.

So your device needs to push some amps. A 2.5 amp limit won't help you with dual coils. That's true for dual coil cartos too, not just RBA stuff. I don't happen to remember the amp limit on the vamo but I think it's fairly high.

I think it has a low-ohm limit, below which it won't fire for safety reasons.

That is very true, maybe im being a bit silly chasing a cloud!!

Reply to AttyPops:

The dripper is reading 3 ohm's. I did not really understand what you mean. Are you saying dual coils are not a good idea?

I mainly started this thread for ideas of dripper setups. It was also for me to make my decision on purchasing a mechanical mod or not.

Well, it's not that bad to learn but it takes some time to sink in and understand the electronics a bit to explain the WHY.

Short answer:
The mechanical mods can push more amps/watts than the electronic mods.

Longer info:
However, your vamo can do a pretty good job. IDK what the amp limit is...I think I read 5 somewhere but unconfirmed. Some e-cigs are 2.5 amps max, so 5 is pretty good!

Anyway...two coils is like having two atomizers side-by-side and powering them both with the same battery at the same time. It takes twice the "oomph". Double barreled vaping. Make sense?

So two 3 ohm coils side by side are a 1.5 ohm dual coil carto, or dual coil RBA. See?

So if your dripper is 3.0 ohms and it has two coils...that means that you either have a bad connection on one of them or you have two 6 ohm coils. You won't be able to power 6 ohm coils. That would be crummy vapor.

Now add to that the fact that the SLR people use heavy gauge wire (28). I use 34 gauge. Some use 36 or 32 also. IDK what that translates to in mm....(goes to google)...

Gauge mm (approx.)
34 0.16
32 0.20
30 0.25
28 0.32
26 0.40
24 0.51
22 0.64
20 0.81
18 1.02
16 1.29
14 1.62
12 2.05

^^^^ That's one chart I found.

OK so that explains a bit about the heavy gauge wire (your .30 mm). It takes A LOT of watts to heat 28 gauge wire. And thicker wire has lower resistance so you'll need to make it shorter to reduce resistance and longer to increase it. Anyway, it's not uncommon for the SLR guys to have sub 1.0 ohm coils and use 25 watts or more. That's probably more than what you want to do.

You can try to crank it up, but the vamo has some limits...and I'm not a vamo expert. I think PBsaro has a longer vid on youtube talking about it but I'm not going to watch it right now. See the vamo APV discussion area for specifications on max watts or max volts.

So basically, use the thinner wire. Wind each coil to about 3.0 ohms. Run at 5 volts. Test the 1st coil before you install the 2nd coil and you'll know.

Get a multimeter if you don't have one.

drill a better air flow hole 1/16" and then low low amount of wicks and 1.4 ohms but you may be able to go lower in ohms depending on your model

Really, there are many things that contribute to a "cloud" of vapor. Outside of the electronic jargon, it also depends on the ratio of VG in your juice. PG is good for flavor; VG is good for more vapor.

Dripping usually gives more everything (vapor, flavor, nicotine, etc...). When I vape with a Joyetech atomizer, my room gets hazy from all of the vapor. You probably just need to work on your rebuilding skills. You shouldn't need to vape at a sub-ohm level to get clouds and clouds of vapor.

I use 70vg/30pg, with my kgo I get large plumes, with my nimbus rba and the 34 awg kanthal, I get mediocre vapor. Perhaps I may have to practice rebuilding.

Ok thanks everyone for the advice :)

Extra thanks to attypops for a great explanation, the chart is very useful.

After this thread and having a read on other threads I'm am definitely withdrawing my temptation to buy a k100. I definitely don't think I am ready.

I am going to keep playing around with what I have already got.

Is a multimeter a must when I have already got the Vamo to check the ohm?

When you are wrapping your coils, do you know the exact ohms you intend to achieve and achieve it? For me at the moment it's more of a 'wrap the coil and see what comes out'.

Honestly, I get pretty darn good vapor production on an 80/20 blend in a T3 tank with a 2.4ohm coil at 4.3+/- volts. It's not QUITE as much as I'm getting out of a 5ohm Artemis carto-tank on my Bolt running 7.4volts, but it is pretty durn respectable as far as "clouds" go. YMMV

Also, how are you satisfied on nicotine and flavor? I kind of feel like this whole "MUST HAVE MASSIVE CLOUDS OF VAPOR! MUST LOOK LIKE A #^(%!*@ DRAGON!" thing is a little... excessive.

Nicotine is fine. The flavour can vary. As I say I'm at a point of just playing around. I only recently got a couple of drippers and started rebuilding them. Before that the nova which I still like.

I know it's not all about making clouds but I felt like the vapour that was being produced was less than if I had an analog, as far as I can remember anyway as it's been over three months now.

I am yet to try 100% vg, I have tried 65% vg, the only plus I found with the 65 vg was that it was best vaped at a lower voltage.

It is hard to know what good flavour is when all you've got is the Internet instead of someone being able to show you in person.

When I wrap a coil, I know my TARGET ohms. The end result will vary from that a bit, which is why VV is so handy.

All-Mech is more picky. So are dual coils since it's doubled.

Multi-meter is not absolutely essential for the vamo+rba, but highly recommended. Doesn't have to be high-end. Some are sold for as little as $10.00...use a real one, not some ohm-meter you screw on. You want a digital one (auto ranging is preferable). Get decent one that's reasonable and within your budget. Will probably last you decades and be handy for other stuff too.

If doing all-mech I'd say it IS essential. There's lots of things you need to test beyond ohms at a connector. Mod resistance comes to mind. Or button resistance. Or voltage under load with a special connector. Etc.

The vamo will show you the net ohms of whatever is connected to it with some ball-park accuracy. You won't be able to check individual coils that way, but you can do them one at a time.

You clearly know a lot more then I do about this, but I would like to tack onto this post it is also worth remembering that my mechanical mods output voltage will decrease as you use the battery/between charges. I've taken to keeping a few 4ohm cartomizers on hand with my bolt so I can lower my resistance as it's voltage output decreases. Helps to sustain a satisfactory vape.
