I'm gonna try some sub 1. Ohms on my next micro cotton ball genesis build (first one heheh). I've been into micro sub ohms and cotton on all my drippers.
I like Twik too in my tank/drippers... Big Ben

Up to now i've been liking por.ceramic wicks with hot wraps or eko sleeved micro's in my Genesis attys...

How I do my rsst. I wrap on a drill bit first but when doing a horizontal coil, I hold the bit horizontally and start my first wrap under the bit. This puts the negative leg on the bottom of the coil and the pos leg coming off the top. I place my coil almost right over the neg screw, this keeps the wick hole unobstructed so I can easily drop yarn into the tank then put the loose end thru the coil. I could post a pic later if needed.

Uber cool uber!! It was almost gone anyway so i just took what remaining yarn I had in my vertical coil out. Fired it to get all coils hot, stuck a drill bit in and made it horizontal. Positioned as you suggested. Wet the yarn a tad. There it into the tank, with extra in the bottom. Threaded the top through the coil. Bad a bing! Wicking great so far. I don't see having to touch this coil or take the tank apart for a long time! Rewickable on the fly

Thanks!

How many coils is considered a microcoil? I've done 6 and it didn't seem to be enough. It didn't cover much surface area.
its number of coils AND wraps touching... even 6 can be a micro, but on the low end. the coil should fire from the center out, no hot spots.
I'd say 6 to 13 at the very most.
There are variables: wire diameter, the ID of the coil, the resistance you are aiming for, the area of the atomizer in question.... its like a math equation.

I'm trying this micro-coil with cotton balls in my AGA-T and AGI tonight. Does it matter what type of cotton to use? I sent my wife to the drug store and she got me some sterile cotton balls. No mention on it about bleached or cleaned with Peroxide.
@ricks...
some don't care. they even use cotton from a Q-Tip.
If you can find some sort of "natural" or untreated, i would guess its better.
Some are boiling it for a few minutes and drying.
I've used "natural", or "organic"... you only need a tiny portion; like one ball / puff would last you forever.

I'm going to do Rip Trippers method "auto drip" from his youtube... looks killer. also on the Vapinaze site Turn your AC9 into an Auto Dripper – Vapinaze

I am about to make the tight micro coils now for them. I will be using 30ga wire. I want to get it around 2ohms. I guess that I will need 12-14 wraps??? Maybe?

No I get this 100%. I primarily use 28g Kanthal. I'm just trying to get the perfect vape. Some say 1.5ohm microcoil can put out as much vapor production as a 0.7ohm can.

And I also wondered. Is it better if the coils were tightly wrapped around the cotton or better if its loose?

hmmm 30g would be a little more wraps than say a 32g for 2.Ohms.
I'd say 30 would be great, because you would get more wraps than the 32g (because 30 gives less resistance with more wraps).
fyi, I just saw pdibs post that you need 8 to 12 wraps to get the benefits of micro coil.

It depends on coil diameter which adds or subtracts from overall length.
Without know how to measure the length for that resistance (including legs to posts)... I'd have to guess.

The RT youtube showed an example for like 1.6 ohms.
With the wick hole diameter around what, 2.5mm? you may need to experiment with lengths.

not tight. it could choke the wick.

the coils for the genesis attys are usually just a mm less than the wick hole, but if i had a 3.5mm wick hole, i would not go much over 2mm ID. but ymmv.

the video's show using a 5/64" or 9/64" drill bit...

if you are comparing 1.5 Ohm to a .7 ohm vape, you would consider the watts too... imo you would need about 15w or more to get that vape :)
does your device allow?

I made the coil using the 30ga and wrapped a 3/32 bit. My AGA-T has a 1/8 wick hole. I had about 15 wraps but it came in at 3.5ohms. I removed 4 or 5 wraps and brought it down to 2.6ohms. Will fire it up later tonight. I have to find my 28ga to try another day. I know I have some somewhere in my stash.

more wraps than 8 to 12 gives you lag time between firing and response at coil.

Hell I'm only used to doing micro's with cotton ball on drippers and drip/tanks so far, and Reo RM2 and Cyclone b/f.
Those you need tiny ID.. 1/16".
With 26g nichrome (less resistance than kanthal) i get a .5+ Ohms with 8-9 wraps lol.

I'd stick with 30g even with the wider wick ID for 2 Ohms

simulating a sub ohms vape with a 1.5 Ohms coil...
just did a little thinking on an Ohms calculator... .7 Ohms at 3.4v = 16w, and 5 amps... i can do this on my DNA20.

if you hit a 1.5 ohms coil with 4.9v you would have 16w, and 3.3 amps with a VV/VW

I can guess that's what they meant.

(on the .7 ohms side, i'm sure they meant with a mech device - which at 3.7v and .7 ohms, you'd have 20w and 5 amps)

I only have Mech Devices. Never any VV/VW. So I'm working with 3.7v all times.

To clarify. According to ohms law, I'm well aware 0.7ohm and 1.5ohm microcoil pull different wattage. BUT, I've heard since a microcoil touches each other and covers more surface area, it's much hotter resulting in quite a bit of vapor production and in some cases better flavor. My question is, is the vapor production about the same with a 4/3 wrap single coil build on a dripper?

I was hoping you guys could test it for me.

a 4/3 on a dripper, silica wick ie... standard wrap... if its done right is a nice vape given the right power.
Drippers do well with micro coil because as you say, juices covers more surface.
The variables determine if you do if optimally... i'd say the flavor is a bit better; thats why its done.

.7 conventional wrap vs. 1.5 micro...to say it is "equal" is only to say that micro will improve some factors of the vape over a conventional wrap 1.5 coil. (ie. HH357 vs reg. 510 atty) imo.

a .7 micro coil is also better imo in some setups than a .7 reg wrap (geni or dripper) ... and cotton ball seems to be the wick of choice. (see cotton ball wicks for info)

Thought I'd share what I'm doing w/ my AGA-T2, been on the same coil and wick for the whole week with killer results. What you are seeing below is sort of the combination of two techniques: one involving resting cotton underneath the coil directly above the fill hole and the other "auto dripper" wick design, as it was dubbed.

Where to begin? Well, it's a microcoil directly above the wick hole, I think I used 8 wraps of 30g though I cant remember for sure. The key is getting a nice clump of cotton underneath it, so it's a bit wedged underneath but not too tight, and on either side, clumping it against the coil so the sides, particularly the wires heading to the posts, have contact with the cotton. The critical part is that once setup (and wet), that a tiny bit of the wick hole is exposed(see picture). In my case, I just use one of my long nails to wedge underneath, and lift a little bit if needed (you dont need the cotton going down into the hole, and it can block the exposed space which will give you red coils after a few hits if it does, so lifting it up a little can help). As long any amount of that hole is exposed, it works flawlessly.

There are two open holes, one underneath the cotton, and the one you cant see on the opposite side. The hole on the right is just plugged w/ some rubber. The back hole has to be open to create air flow or the cotton wont wick and you get red coils. The hole on the right that's plugged, is to be opened while refilling or you wont get any juice into the tank without using a syringe due to a lack of sufficient air flow.

From a full tank to a few drops, I use it exactly the same way. Before every drag, I just tilt so the liquid can reach the wick hole, maybe for a second at the longest, and then take a drag or two. Every tilt will instantly rewick the cotton, and with enough cotton, you'll have enough for a great loooong drag without having to tilt during the actual inhale. Depending on how much cotton there is, there may be enough for multiple hits before tilting, but I have had no harm in taking no risk and just tilting to rewick before every hit, and has worked everytime.

Been using the same piece of cotton all week, between 15ml and 20ml of juice total, and readjusting slightly with each refill if needed to make sure the hole has that sliver of exposure. Can see the coils are pretty gunked up and in need of a dry burn, but it's still performing great. The whole setup is similar to my IGO-L, just with less cotton. The real difference, I just tilt to rewick instead dripping, which is convenient as hell. As it gets gets closer to empty it takes a bigger tilt, more than 90 degrees, which will be visibly obvious and towards the end when you have only thick syrup left, it takes time for it to ooze down to the wick hole.

:evil::blink:LOL... it makes me wonder if this is what its all come down to for Genesis atomizers... some of the dudes that i respect in that arena, who showed us how to make SS mesh, FC2k porous ceramic wicks and wraps, are now using cotton ball tufts and Micro coils.:vapor:

I can't get over the fact that it has taken me a good year to finally get those wick/coils somewhat down... what a royal pain its been over the last couple of years. haha.

I've done quite a few Micro coils in drippers and tank/dripper RBA's, with silica, eko wool, cotton, et al and its been hell of a lot easier and fun, but still in my mind I just don't feel this is the end of what used to be Genesis atomizer vaping as we know it.

Its not, really. Currently I'm waiting for an AL-1 from the makers of the AC9, for that cotton ball setup with the vertical Micro coil, but as far as the Geni's i still have, a DID, and a Hydra Ti with more conventional geni builds.

DID- SS cable with an eko sock under the coil "micro" .7 Ohms
Hydra Ti - FC2k with hot wrap .7 Ohms
These have worked so good, I don't want to change them out. I've learned that once you have a great setup, you can use them over and over.

Before this, I tried an dual coil Eko wool wick micro setup at sub Ohms too... not bad, but not worth keeping, on my DID.

It just feels like sacrilege.... :evil:

and my Changeling Ti setup on my BBM Ti has a hot wrapped fc2k at .6 Ohms... :evil:
