Greetings from a new member .. That’s not so new

Hello everyone,

I found this site today after I received my 510 Redux ego kit in the mail. My username was taken, which is always odd, so I figured out I had signed up back in 2010!

Sooo.. Before receiving this kit, my first ‘real’ kit, I had been using a completely custom one that I had built after trying the first iteration of eCigs. It relies on a large battery and wires and junk. So you can imagine how happy I am to be mobile with my vaping, and not having to worry so much about spilling and what-not.

But yeah, I’m new. Posting my first post. Saying hello. Hello. 🙂

Putting an O-Ring under an EGO/Evod twist center pin to fix it.

Once upon a time I thought I saw a fix for putting a new o-ring under the center pin to fix the constant need to pull the pin up to get a good connection. I can’t find it. Searched You-Tube, Google, no luck. I’m placing a FastTech order now and want to add a pack of 50 O-Rings for $1.00 to it, but not sure what size I need. This is to use with generic 1300mAh ego Twists. I want something to slip over the center pin to give it a more permanent fix. I’m looking at this page now and very confused Found 490 o-ring at FastTech – Worldwide Free Shipping They are all in Height, Width, ID, OD, What do I need to slip over, then under an ego center pin? TYVM for any help guys!

Hi, ECF Members

Hi I am glad to be a part of this forum. I have been vaping for some time now and have been doing a lot of research.
I always seem to be coming back to <acronym title="e-cigarette Forum”>ECF or taken back here do to my searches.
I have found a lot of very useful threads and some very helpful vapers , all willing to input good and helpful information.
I have never read a sarcastic or rude thread in all of my guest visits. so that is why I finally decided to join and become a part of the group (if you will have me).
Thanks to all that are members of <acronym title="e-cigarette Forum”>ECF for being very inviting and to all of us who ask stupid or confused questions. We need your expertise and help.
Thanks Again… Thank you also smokey Joe.:D

Recycled Gear Adoption Depot idea

Every now and then random ideas come up in my head.
But, something I haven’t seen yet and would greatly benefit everyone (Especially the new to RDA, RTA’s or vaping in general) is a gear adoption depot (yah, that means free). We all have used stuff sitting around, old atomizers and mods that had seen their day but new shinny things came in to play. So was thinking about the possibility of maybe <acronym title="e-cigarette Forum”>ECF or even the moderators getting together and starting the "Gear Adoption Depot" thread where new folks could find old gear on the free. This would be a pay it forward kind of thing I would think as they upgrade the item is cleaned (please, that would be just gross not to) and put back up for adoption again to someone that needs or can use it.

It would be a first of its kind that I can think of, and most def. appreciated by a lot of folks.

Just a thought, chime in and let me know.

Sincerely,
Midnight

Need advice for which gauge to get for different ohm goals

Currently I have 24g Kanthal, every build is generally between .3 to .5 ohms. I am wanting to start building coils that around 1 to 1.5 ohms but i cant logically do this with 24g in my RDAs or RTA. I currently own a Brass Monkee RDA, a Tobh 22mm Atty, a Vulcan 22mm RDA, and a Lemo RTA. In the Lemo my build is a .7 with the 24g but i can build a .9 with the wire that they sent with the tank but sadly they dont tell me what gauge it is. In the RDAs its still .3 to .5 (Latest build is a .3) I believe what i have wrapped atm is a Micro coil but i could be wrong, its wrapped around a Screw driver that is similar to the drill bit size for micro. Anyways, Could anyone help tell me which Gauge Kanthal makes which different range generally? Looking to just get a 250ft spool of the wire once i know which size to get. Much appreciated!

Pineapple Upside Down Cake (Complex Recipe)

This is one I’ve messed around with and quite like. It requires at least a week of steep time, preferably 2 weeks. vaped right away it tastes way too muddled. It’s probably more complex than most want to mess with, and probably more complex than it needs to be. A lot of the flavors are pretty similar and could probably be left out and replaced with more of another with similar results. But, I’ll post it anyway for those who don’t mind mixing, and have a large collection of flavors. I’m a dripper, so this is an 80/20 VG base. I didn’t keep up with brands, but 95% of my stuff is TPA, and a few are CAP.

I do this in a 30ml batch.

80/20 VG/PG Base
6% – 100mg/ml Nicotine 50/50 Base
6% – Pineapple
5.6% – Cake Batter
2.6% – Bavarian Cream
1.6% – Vanilla Custard
1.3% – French Vanilla V2
1.3% – Whipped Cream
1% – Brown Sugar Extra
1% – Coconut
0.6% – Toasted Almond
0.6% – Butter

1% – Sweetener
0.3% – EM
0.2% Smooth

~22% Flavor

The smooth could probably be left out, but I found the Pineapple had a little bit too much tart/harsh flavor. It seemed to help a little.

Twisted Ni 200 and Kanthal, correcting the DNA 40 temperature setting

The short and sweet: Due to the resistance difference of kanthal and nickel, the DNA 40 device will need to be set lower than the wanted temp.

To achieve 410 F, with 32 (or 30) gauge nickel and kanthal, set temp to 340 F. Using 30 gauge Ni and 32 gauge Kanthal, set to 370 F (best match I found)

Now the ugly math part

cmf is circular mil foot, circ mil = 0.001". Keeping cmf constant, the Ω cmf is the resistance change due to temperature. The ratio from the 70/200/400/600 data points forms the cardinal resistances in the table below for 32 AWG Single Ni. Interpolation fills the rest of that column. The 32 AWG Twisted Ni gets it’s factor increase from table 2, at 15 turns per inch, 1.067872 times the single resistance. Yeah, I know the factor does change somewhat when mixing 32/30/28 gauge in the twist, but I don’t think it’s enough to make much of a change on the final results.

The Single K Ω comes from the single Ni length (table 3) times it’s Ω per inch (table 1). Twisted K Ω from single times the same factor used for single Ni (1.067872). K (kanthal) resistance stays fairly constant in the 70-600 F range.

The ## Ni ## K Total Ω = ## Twisted Ni Ω times ## Twisted K Ω divided by sum of ## Twisted Ni and K (Parallel resistance formula).

Setting DNA 40 device for left-most column temp, found under "Set device temp". Example: want temp of 410 F, set DNA 40 device to 340 F (for 32 AWG twisted Ni/K).

It’s interesting to note that 30 gauge Nickel and 32 gauge Kanthal twisted, gets the smallest correction factor to the DNA 40 setting. Makes sense, as in parallel resistances, as the larger value gets further away from the smaller resistance, the less effect it has on the total resistance.

Well, there you have it. Most likely there are some mistakes here, I’ve tried my best. I did make some measurements on wire resistance, single and twisted and they did come out in the ballpark of instrument accuracy. Only thing I didn’t have was a thermal gun to check actual generated temperatures.

That’s it, thanks for your time.

Trying to help a buddy

Hello all, my buddy came to me today and is looking for a mod that he can run the atlantis tank on. He’s looking for an all-in-one regulated mod. Preferably something he doesn’t have to change out batteries in. I’ve read the MVP 3 coming out later will be possible of this, but is there anything out there right now that’s affordable and good for a someone new to sub-ohm. I’ve checked a few of my common websites and haven’t ran across anything yet. Any help on would be appreciated! Thanks in advance!
