Now you've got me thinking gutter. I could come up with a good size rheostat and vary the resistance to see how the stick output varies according to load. A lot of the ones I use at work are high wattage and usually in the 0 to 15 ohm range. See what you did. I'm not having problems but you've got me thinking about it.

it would be interesting to see for sure -there's definitely something wonky going on when the battery is fully charged. this one seems to calm down and even out a whole lot once the battery meter hits that first discharge mark.i guess it could be a combination of how they are doing the regulation as well as the filter in it or if something is right on the edge of the amperage limits with a fully charged battery , it could be partially letting go untill the amperage drops into the perfect range for it.surely it's not a jfet based thing...

*edit*
hmmm...

    Somewhere between here and there
    My problem right now is that I'm over a week behind at work and am not supposed to bring my scope home. I'm wondering also if maybe you got a bad istick since you're having issues and me and OTD each have two and are not. Might be worth emailing the vendor and see if they would do a warranty swap. Maybe the regulator circuit isn't working in yours or maybe it's intermittent.

    so i had some time last night (and today even!!!) and i think the istick is working correctly and may have figured out what is going on.
    looking at pbusardo's chart here (at the 25:14 mark):



    and with calculator in hand,setting the provaris,istick,itaste and vamo (in mean mode)all at the same settings (taking the offset from the charts into account in the case of the vamo and eleaf), i'm getting roughly the same experience between devices,across different toppers. the vamo and istick are harsher and tend to be more burned tasting with more heat and a thinner vapor where the others are cooler,smoother and tend to be sweeter overall.on the nautilus, i had been running them with 1.6 ohm coils and the airflow control wide open (which closely mimics the setup i've been using in the drilled out kayfun) and this setting exacerbates the harsh,dry aspect even with the higher ohm coils and on the kayfuns (wound to 1.6 and 2.2). if the airflow is tightened down or wicking holes in the coil drilled out, more juice is siphoned to the coil and cools it off a bit and sends it closer to the range i usually gravitate towards.

    now the important thing is,
    in the course of all this fiddling, i figured out that what i gravitate towards is a fairly specific cooler,more open draw setup at right around 7.5 watts with a +/- 1w variance depending on coil mass and heatsinking ( on the provari,it works out to 3.5v @1.6, or 4.2v @2.352 ohms -which is what i was shooting for on the eleaf before the calculated offset due to the "incorrect" power calculations it is presenting). i've seen 3 or 4 charts now that show the istick is incapable of these settings with a fully charged battery and using the higher resistance coil in the kayfun with its' added heatsinking and juice delivery capabilities explains why it was acceptable (and dare i say it? ,great!) with a partially drained battery.
    all of this to say - the kayfuns added airflow,heatsinking/thermal mass/whatever you wanna call it coupled with shorter draws and increased juice delivery offsets my gripes even with a fully charged battery AND a lower resistance coil vs the nautilus (which is noticeably hotter feeling in the hand after useage at the same settings as the kayfun).

    also, as an aside, the itaste vv when set to identical settings to the provari,with the same topper is scary close. i had never run them dialed in identically next to each other before and the provari is just a touch smoother but they are really,really close to the same experience.

    Good for you Gutter! Feels great when the puzzle is solved. I know just enough to be obsessive enough to want to follow thru to the end but not enough to always get there. Hahaha. I know nada about the new and improved bottom coil dealies. Back in the day of ProTank (1and 2) I got so tired of funky heads, intermittent taste, and waste that I went back to cartomizer tanks and then rebuildables. I'm sure they've improved greatly but I'm happy in this spot.

    Dare I say that the Kayfun stepped up once again? Hahaha. At least for your cooler taste pallet. I prefer the same.

    Now, sit back and enjoy the results of your research....

    yes it does.well, it makes you feel less crazy, anyway :)
    to be fair, the bvc is worlds away from the old wick based heads.i've had no gurgling, leaking or burning/dry hit (well, up untill this deal) issues that were so prevalent with the older tank systems. honestly,it's really more about knowing the ins and outs to be able to help the smokers i know with troubleshooting or accurate suggestions for hassle free starter equipment (i.e.,you can't really know the intricacies of something unless you spend ample time with it)than it is about looking for my own satisfaction.

    for my own personal preferences, a kayfun with a microcoil on a provari gives me more than enough options to get something i like out of any juice where i don't have to worry about something crapping out but, i don't feel like throwing a beginner into a tank system where they have to tweak the coil,filler,airflow,etc.. precisely or a battery that is gonna cook the heads in their iclear or whatever without knowing why is an acceptable first step to getting them off cigarettes.

    short answer being, some of the things i don't like about the kayfun are actually what make it work in this scenario.strange how things work out sometimes,eh?

    and yes ma'am - i will. slack time is commencing shortly and brain function will be minimized for the rest of the night :)

    I hear you Gutter. The ecig industry has gotten better just in the short time I've been around but can still be challenging for new folks. I have a friend (yes, I have friends..hahahah) that got tired of funky heads with the previous generation of clearos. I turned her onto carto tanks (with a lengthy prime lesson) and she's a happy puppy. Last month I needed to borrow back one of my carto tanks as I was going to be traveling thru big elevation changes (100 to 9,000 ft above sea level). I must say that even though their draw is long, the flavor is doggone good. IMHO, carto tanks are the easiest, yet most flavor next to rebuildables (of the stuff I've tried). And yes, very very little leakage! (I learned from a truck driver elsewhere on the Forum to store them upside down.). So thankful for this Forum. I guess if the ecig industry evolved to perfection, we wouldn't have a need for it. :(.

    Must go and gently shove someone off the throne, while I enjoy some P-38. Good news there: Ms Chris says that it may be restocked by the weekend!

    Congrats gutter. I saw where you mentioned running the mini on one of the bigger air holes. I run mine on the next to the smallest one. I like a bit of a tighter draw.

    funny how one little variable can make such a huge difference in a setup,eh?

    the sharing of knowledge and sense of community are the greatest things about the whole ecig experience - i talked to a buddy of mine (that i helped quit smoking)the other day and by his count, he had helped 15 or 20 people quit directly and most of them had done the same and it really sunk in just how important that aspect of it is due to the potential exponential numbers of helping people quit that there is there.He was saying that he had heard that his ripple effect of helping people quit reached as far away as connecticut and that he had indirectly helped almost 100 people get off cigarettes. all of that from me giving he and his wife some snus and a pair of 510 batteries and carts and showing them how to tweak them 4 years ago.

    things move so fast at this point, you just can't keep up with everything and there's bound to be things that throw you for a loop having you guys (and the rest of the forum) around to bounce ideas off of is invaluable . Hugs all around!!!!


    hehehe

    screw you guys,
    i'm going home!

    So that's what I think I was tellin' ya gutter with respect to the airflow. Somewhere. some thread....
    But I didn't exactly wrap up my thoughts so yeah, tighter draw pulls liquid into coil better which is needed to avoid burny taste.

    I'm tired.

    Good vapes all.

    it's those dang drippers that did it to me. i didn't used to care much about draw....now if something is tighter than sucking through a straw, i feel like i'm being repressed!!

    I rotate 2 DNA30's, an IPV1, an IPV2, 2 MVP2's and tomorrow will pick up my Sigelei 100. I have 7 Kayfuns to go with them. I have tried just about all RBA's and have decided that, for me, the Kayfun is the best. I also do not like an airy draw. I want something that draws like a cigarette even though I have not smoked for over a year. I also have a VTR that I use an Aerotank for.

    I'm the opposite. If a device is too airy then I most likely sit it aside and never go back. Hard to imagine not having airflow control available.

    airflow controls are great.... as long as they're wide open :)

    gotta blow muh EXXXXXXXTREME cloudz brah...




    (ugh... i think i just threw up a little just from typing that)
