What hardware are you using to get the best out of your aroma juice ?

[hittman]

If you look at the istick threads out there you'll see that everyone says the isticks seem to run hotter because of the type of output. I had a similar situation when I got my vamo. It will run in both modes. I've seen a few recommend the 2.1 bvc coils for the isticks. That's what I have coming for mine. I wonder if anyone else has noticed a more airy draw with the aspire bvc coils( not talking about nautilus).

As a MVP 2 and Istick owner ( using the same tank on both ) i can confirm that Istick is running hotter with the same settings as the MVP (8Watts).
My bvc coil shows 2.0ohms on MVP2 and 1.9 on Istick...so i think thats the difference. The voltage would be higher on the IStick to produce 8watts

I also have noticed that a brand new aspire bvc is almost too airy for me, but after a while it tightens up....

Yup hitt, fully aware of the RMS/Mean Average thang. 1.8 BVC working well on the stick and yes. they are airier then the BDC's.

I tried one in a mini aspire and really had a difficult time getting used to the difference in airflow. It seemed better in the ET-S which I always thought needed more airflow. However, with a more powerful battery behind it like the istick they might be fine. I still run a lot of the vv3's and twists.

thanks man - that's what i eventually surmised. i was running 1.6 bvc's and it was just too dang hot even at 3 "volts". i messed with higher resistance coils and wicking in the kayfun last night and have it dialed in a bit better now - when i empty the kayfun out, i'm gonna drop in a 1.8 ohm coil in the nautilus and see what's what.

The iStick is infamous for running way hot. I still haven't gotten mine "calibrated" versus my iTaste VV V3.

 

[hittman]

I just got mine and I've got an aspire bdc I usually run at 8 on a vv3 is set at 4.7 on my istick and still seems warmer.

 

[olderthandirt]

Mini Nova with 1.8/9 ohm BVC on the iStick all day today.
Started at 3v and ended up at 4 to 4.2v most of the day. Not as much vapor as the BDC's but the flavor is greeeeaaaat!

 

[hittman]

So far the mini aerotank at 1.9 ohms and 4.7 watts seems good.

That's my setup too -- what flavors are you vaping at that setup? (I assume you're still talking about on your iStick, right?)

 

[hittman]

Yes on the istick. I've got bright leaf wta in it.

strangely enough, i had a bad vape day today. i don't remember the last time that's happened? everything just sucked

the eleaf came in today, i threw a nautilus mini on it at 5.5 watts and BAM! burned filler city.swapped out the coil just to be sure and BAM! burned insulator city. dumped the juice,pulled the whole thing apart, put it in alcohol to get the burned plastic taste out of it,threw on a drilled out kayfun with a 1.4 ohm coil in it and it was burned juice city.at this point, i'm ready to call shenanigans on the "11watts with a bvc" crowd and their tastebuds and started referring to it as the iburn......
anyway, i ended up winding a 2.4 ohm coil in the other kayfun and threw it on there and it seems to have cooled it off enough to get some range out of it.it's sitting a hair under 7 watts but still seems like the flavor is lacking.

A bad Vape day is a dog-dog-waste-of-a-day! Ever since I started watching that DNA video, I keep thinking about the statement that power and heat are very different. Is that what might be going on here?

who knew that could even happen anymore? after almost 5 years of fiddling, you'd think i could dial something in quicker than that

the whole power/heat situation is part of it robin. when you start dealing with pulse width modulation, there are different ways to calculate post filtering output voltage and the eleaf does it the "wrong"way for our purposes (iirc the e-cig manufacturers figured it out around the time the v1 vamos were out in the field as the later versions are switchable between the method the istick uses and a more precise or "correct" method) and thusly generates more heat than we are used to for the provided numbers.


(second video added in next post due to limits)

at the end of the day, all that really matters is how much heat you're actually getting out of the coil and how accurately it is generated - the voltage is sort of secondary and just a means to achieve the end goal.we all just got used to just having two controllable variables in the equation for years (voltage and resistance) and now that e-cig manufacturers are getting up to speed on the ins and outs of power control and pwm and how it applies to us,it becomes obvious when someone at one of the companies misses something (i'm looking at you eleaf ).

all that should be taken with the notion that for 35 bucks, what they have put out is astonishingly good - this is all just nitpicking asshattery.

Nice explanation Gutter. In the end you're right though. For the $30 ish range you're getting a great little device with a digital display. I really don't care what the number says on the screen as long as it vapes well.

One of these days maybe I'll get around to doing a chart that shows standard RMS watts (what everything but the iStick uses these days) versus what the iStick displays at various wattage increments for a range of coil resistances. Also be aware, at certain resistances it's not able to hit its full advertised range, both at the high and the low end. (Details in Phil Busardo's video linked below.)

Based on his comments in the video linked below, plus some comments in a more recent vid where he says he's been carrying one around with him, it's clear he actually quite likes it, even though he gave it a thumbs down. (He says he thumbs-downed it to encourage Eleaf to do it right in the next version.)

Here's the link: A PBusardo Review & Contest - The Eleaf iStick, posted October 14, 2014 (and shot two days earlier). The charts of interest start at about 22:10.

Nice explanation Gutter.

it would be waaay easier to put into layman's terms if pwm not creating voltage without filters wasn't a thing

and for full disclosure, i know just enough about pulse width modulation to know i don't like it .hehehehe.

 

[hittman]

I've been dealing with pwm for years. It's been used in welding equipment for a long time.

my condolences....




seriously though,yeah -sorry man, i was making a bad joke. in power control that's like saying "welp, i know just enough about oxygen to know i don't like it!".

they actually just started using it in audio applications a few years ago and there were similar growing pains with it there at first. the amps using it were weak,prone to failure and just sounded bad in general -now they're churning out 6lb amps that put out 800 watts rms and sound pretty dang good doing it:

Thanks Gutter! I watched and understood about a tad of it but my new mantra is PWM! PWM . I can say that I find the progression of science/technology in the Vape world, to be really fascinating and exciting. I've only been around for the last year and a half and have been amazed and hopeful for the future. (Can only imagine being privy to the last 4 years. The stories of modded flashlights come to mind) . Amazing what happens when great minds come together. Bravo!

Just hooked up a "new" (classy) Svo. Kayfun Lite. Just love the flavor production with these puppies. They are close, if not even with the Reomizer for flavor IMHO. Other than the WTA benefit of Aroma's flavors, I really enjoy the mature, complex qualities of their flavors,

I don't want to brag (because I know I'll be humbled) but I'm pretty nifty with these KFL's! (Oops...I did it. I'll await an ego evening moment). Plus, whenever I have difficulty or questions there a very active Kayfun Lite thread elsewhere in the Forum.

 

[hittman]

Gutter it's the same trend with welders. Smaller and lighter. I work on three phase units that put out 350 amps that I can pick up and sit on the bench where something like that used to weigh 3-400 pounds and didn't have near the functions the new ones do. On some you can do wave shaping.
