Yes, apologies for OT Doggy, just want to map this out a little more here, as that could lay an important foundation for the side road Vaporer is planning to turn off on!
Katya,
Some good info and pics from the link you posted. Thanks. I can see now that there are gonna be as many or more styles of cartomizers than attys. Anyone offering to send any, Only 808(901 threads) or 510 will be of much help as that's all I can connect to. unless they make one for an 801. I don't have a 4081 or an adapter to anything I own.
Re the 4081s, someone is sending me one of those to try plus an adapter to do so with, but I'll ask her if she had anything in mind for it after that. If not, I could send it to you. Re the GreenCigs, while there is also a proprietary batt for that one, it will thread onto an 808 and there are a couple of simple ways to 'adapt' it without buying a dedicated adapter. One is using the 'staple mod,' the other is drilling a small hole into the 'G' of the logo on the carto. If, after I've sent you some, you need links on that let me know.
The pics and links I found showed 2 styles. One had a solid type wrap(sock) and one pic of a new tear down showed holes in the coil area. That was what I was wondering abt. Was the large black hole actually all burnt material or a blackened edge of a pre-cut hole. Then there are the "long hair" type from the link ScottBee had posted in my thread and they have a cart slid down over the "hair" as its the actual wick.
I cant say what I see excites me in a good way with the burnt material. Cartos are supposed to last quite a while, but the material should be kept wet. Questions come up to me on can it feed a long slow draw or hard one? Exactly when does the material start to burn? How often would a top off be needed to prevent this?
Lots of questions to be answered.
The link is a long thread by itself and is going to take some time reading it and the other links from it so I will probably start posting anything else in those or start a thread.
The thread Katya linked you to began about a year ago IIRC, then was most recently bumped sometime in March with the 'overflow' from a heated thread that got locked, and another which got deleted. By the time it was bumped again that last time, there had been some new developments in the world of cartos, so to read about those it may be efficient to pick it up around March, initially anyway. Altho I've participated in it I never read it from the beginning myself -- probably because of all I'd already read and learned in the aforementioned locked thread many of us were refugees from.
Anyway, in the thread Katya linked, from around March on anyway, the focus was kept on possible solutions and the current state of cartos, and there's good info in there on that. But another one, which is also linked in that one IIRC, that would definitely be very good for getting up to speed on the longstanding burn issue
itself, and discussion/debate/arguing over the exact kind of questions you're now asking (i.e., how much can frequent top offs help, etc.) and is also a more recent reference on those aspects, is this locked one I mentioned above:
http://www.e-cigarette-forum.com/forum/kr808d-1/75215-all-my-used-cartos-toast.html
I'll digress to say, every time I refer someone there it's a selfless act lol, since I was one of the first ppl who replied on it and at that time I did not yet know about the burn issue!!!!

Sure felt stoopid later, but it
is true that the OP's level of toasting -- that he could basically see 'charcoal' upon merely peering in, not even dissecting the carto first, was extremely extreme and the part that had really thrown me!
Anyway, lots of pics, and links to other 'classic' burn threads, ended up getting posted in the 'Toast' thread. (No point in recreating the wheel on the parts that have already been discussed intensively numerous times, i.e., how bad can it get, is it preventable, what about this 'preventive' technique or that one, etc. etc.) In 'Toast' you'll also hear references to 'the other thread,' which was another even more heated one running simultaneously in a different subforum, with some of the same participants. That one ended up containing some input from engineer-y types on technical aspects that you may find useful... but later got deleted. However, note that I'd saved a .pdf print of that thread, so when reading 'Toast' and hearing references to it, or if for any other reason you decide you'd like to read that one too, PM me your email addy and I'll send it to you.
If at any point you become interested in reading more about the new higher resistance kind in particular, and the unfolding of discoveries on how they work,
this thread contained a fair amount of that at a point not long after it was first started. (Became very OT in later days.)
Ok, don't know how 'branch offs' are typically handled, but Vaporer maybe you could start a thread in the modders forum that links here for background reading only and specifies that...
However, actually not that much has come up here on the particular aspects you plan to branch into. So maybe it would be even better to start fresher -- begin a thread containing links to some of the classic burn threads you're about to read, as the 'prerequisites.' FYI, many ppl have followed the carto burn issue closely, but off the top of my head, two who have followed it especially closely are Scottbee and AlexTM. Maybe they can help fill in any blanks in the historical maze that you may come up against. However, Scottbee seems to be largely MIA lately, lost to real life and impending-summer boat prep and family fun or something silly like that!
