Booty clouds, okay flavor.

So I just recently did a dual coil build, and the vapor production is awful. HELP.

My current set up is:

• A Smoktech Magneto V2
• Sony VTC4 1600 mAh 3.7V high-drain battery (charged with a Nitecore Intellicharger)
• Omega rda (clone)
• 100% organic, non-GMO cotton wick
• Dual coil build: Four wraps around a 1/16" drill bit - 28G Kanthal

hows your air flow? make sure your wick isnt blocking your air holes. are both coils heating up evenly and glowing red? whats the ohms of your build?

 

[iraqlobster]

I always make sure the cotton isn't blocking the air holes, and I honestly don't know. I'm too poor to get an ohm meter. Poor decisions and low budget vaping at its best xD

 

[Singaw]

Since you didn't say I have to guess and I hate guessing but I guess that is about .25 ohms and should work fine. What PG/VG mix are you using?

 

[Metaljedi]

I wouldn't even be vaping on that without testing the resistance. I'm too paranoid about the battery blowing up in my face.

Can't afford a $5 ohmmeter? You can probably find one for a dollar at yard sales or borrow one. I have a feeling you are playing with fire and will get burned.

An ohm meter with a 510 connection?

A nice easy vapor chucking build full of flavor for me is the stovetop coil 5 wraps 28g kanthal cotton wicked line up you airholes rite in fron of the coil and be prepared to make some steam. Rip trippers stovetop coil Youtube
I built my in 26g kanth. cotton wicked in the Smoktech caterpillar RDA and its insane .19 ohm on the magneto or the panzer makes Gaging dense vapor and flavor is on par with the kayfun easily

Any multimeter will work, there are a few videos on youtube with instructions on how to check the ohms of your atty with a multimeter. It's what I use every time I make a coil.

 

[Metaljedi]

yeah they sell them everywhere specifically for checking your e-cigarette coil resistance. they are like $25 at my local vape shop.

Good look. Thanks man, I'll look into that. But either way, I've been doing this for a couple of months now. I feel as if I should be fine as long as I don't do anything like a .1 ohm build - although I have seen people do .1-.2 builds before.

I personally wouldn't use these I find way to much variance in them and the ones I have used have been much less then accurate compared to my fluke meter. The do make nice build stands and are fine for making sure there are no shorts before heating the coil up on the mod. go to Radio shack and buy there entry lvl meter its $19 and accurate. make sure with any meter you put the leads together record the resistance then measure your coil, subtract the resistance value found in the leads this will give you the true OHM of the coil.

The meter I use is a very old analog unit that has an adjustment screw to zero the ohms. Some of the digitals like fluke auto zero if you touch the leads together. Just read the manual I guess but that's a good point epicdoom.

yes the fluke will calibrate it you touch the leads together and turn the dial to Ohms scale. I have a big Simpson analog for reading Potentiometers, but its like lugging a toaster to the coil building area lol IMO analog meters are still the best some digital meters cant determine well between readings. so they bounce around between readings an analog will hold still on the reading and if there is any fluctuation you will see that needle bounce. the adjustment screw on the analogs is also a big help as some digital meters wont calibrate you get what you get, lead resistance can show as much as 2 ohms over time. with no way to adjust this out your forced to use math or buy new leads.

I do a good bit of electronics work personal and pro I'm a meter and lead, probe, jumper fanatic I have pretty much every modular system and test lead kit out even have a few I custom made for back probing and testing sot 23 size terminals. I good meter is at the heart of it all.

I just read something today by a very experienced cloud chaser/ sub ohm guru who said he never goes below .3 ohms because there's not enough margin for error for him. The build you're discussing could be .25 ohm like someone else here said (which is under that guy's safety limit), or it could be zero ohms because there's a short somewhere you can't see or don't notice. You have no way of knowing if what you're doing is really unsafe or extremely unsafe unless you test your coil.

Now here's the big rant:

This is the second time in 2 days I've seen someone say "oh, yeah, I'd definitely test if I was doing something that could be dangerous, but I'm just doing a simple build so I don't need to," and 1) they *were* doing a build that could easily be dangerous (.24 ohms is NOT a beginner build), and 2) even if they weren't, ANY build can be dangerous - it's really easy to accidentally touch the wrong thing and short your coil. Even if you're building a 3 ohm coil, a short is a short. And shorts are how batteries go thermal. I absolutely guarantee you that Rip Tripper or whoever you're watching on YouTube tests EVERY coil he builds before he fires it. I've never seen a build video where the builder doesn't test their coil. So where are you people getting this idea that you don't need to? Do you think you know more about building coils than Rip Tripper?

Firing a coil, ANY coil, on a mech mod without testing it first is playing Russian roulette. It's stupid and it's dangerous. And one of these days, someone is going to hurt themselves very badly because they tried that. I hope it's not you.

Please out your rba away until you have something to test it with. Vaping doesn't need the bad press that would come from this kind of accident right now. They're already on the verge of banning everything except crappy cigalikes. We really don't need to give them more ammunition.

I like building coils. I'm considering getting a mech myself, because the sub ohm flavor is awesome. But the more time I spend in the new members forum, the more I'm starting to think you should have to pass a written exam to be allowed to buy a mech.

I would like to add comment to novamatt's rant.

I have been building coils for about 6 years and test every single coil for two things before I place it on a mod. I test for shorts and for resistance which takes me a grand total of about 5 seconds to do. Out of the hundreds of coils I have built most have tested perfectly where I wanted them to be but I also caught myself doing a few stupid things that could have ended poorly for me. One evening I accidentally built a double coil out of the wrong wire which left me with less than half the resistance I was expecting. If I never tested the coil I could have very likely been trying to vape on a ticking bomb. I can build any coil I want in any resistance I want but my dripper is always set up as a .9 ohm dual coil because it works well for me and is relatively safe. I build 1.6 ohm single coils for my Kayfun lite and that works great for me. I don't understand why people with practically zero knowledge of what they are doing insist on trying to build sub ohm coils, it's like falling off a bike the first time you ride and deciding you are ready for the biggest, meanest crotch rocket. Just plain stupid.

I was just having this discussion today at a local B&M shop. One of the regular non builders was there buying wire and wicks. I know the guy on a personal level, so I said don't forget to go buy a meter to test what your building. His reply was I'm building a .4 ohm duel coil for this new dripper I bought, the shop guy here told me how many wraps for the size wire I bought no meter needed. I felt like slapping the stupid outa him, but I refrained and explained he is playing with things that require a bit more then hit or miss tactics. I told him to stand rite there and don't move, I went out to my service truck and grabbed my meter. Went back in the store and showed him how stupid it is to make coils that way. And how its especially stupid to assume it isn't shorted anywhere when using a mech mod.
There are many programs that will figure resistance for you all you need to do is put in wire size and length even some that will calculate how many wraps to make around a given mandrel size for a desired resistance. What they don't do though is tell you if you have a short and they are based on new fresh wire wrapped at a certain tension. In the end All we can really do is suggest folks learn more about this stuff before attempting it.
