Eleaf Istick

[scaredmice]

I quit reading the last 2 pages because I'm somewhat irritated by what's being said. First off you can't measure a digital output with an old analog meter - just won't work! Second, a lot of folks are kinda trashing the istick saying that it is using a Vavg calculation to determine it's output when we don't even know what method it is using. At least I haven't seen any reviews stating that by a respected reviewer with the appropriate equipment. I think some folks are jumpin the gun quite a bit.

Well, some of those folks have bought the istick now ........

And they are pretty sure they can measure an analogue output (don't get confused, it is not digital, like a current with a binary stream over it, it is just a squared, or more or less squared, wave, good old analogue wave) with an old (well, mine was bought less than ten years ago...) analog voltmeter, and if memory serves, it'll be an V_RMS reading.

Only analogue voltmeters coupled with special filters were able to measure averages and peak voltages, except for really low frecuencies.... But I've read something about a 48 MHz squared wave as output......

I've also read 48 Hz... but I think that in those messages some Mega- prefix got dropped by mistake.... An 48 Hz output would be absolutely audible, and it'd look like an AC inhouse current from European AC supplies... quite weird.... Going on weird things....has anyone with a dog checked out if their advanced VW got busted by their pet's extremely sensitive ears?

I think Provape works beyond the two hundred MHz, tha'st far beyond the ultrasound range for mammals ( has anyone a bat as pet?...), but the Chinese-built APV's work somewhat between 33 and 66 MHz.....

Since this is a Big Thread. Refresh My Memory.

Do you Own an iStick?

I've paid for one but it hasn't shipped yet; pre-order from vapenw. I'll get some use out of it, even if not ideal,... especially for the money. I also want to get it on my scope and put it through the paces. No telling how long Mr. Busardo will take with his review...

 

[ccwaters]

That's pretty darned good. At the very least a readily available bezel would clean it up rather quickly.

Thanks for the pic!

Yea a bezel would work, I'm a bit of a cheap SOB so I didn't bother

Gotcha.

Maybe when you Get One you can Post what you Like and Don't like about it.

BTW - What Ohms/Watts is Your Average Set-Up?

 

[Fergie]

Now I've heard everything.

I'll do just that, zoiDman. I may have a big mouth sometimes, er... pen... er...keyboard. But I'm not dense. I'll refrain from further comments until further data has been obtained... Enjoy your iStick! It certainly breaks all the current rules of APVs!

I'm currently running my Kayfuns @ 1.4, clearos @ 1.8, RDAs for regulated mods @ 1.2 (single twisted coil) and RDAs for mechs @ .6 (dual/twisted). This is where I've found the best all around performance for me.

I run the Kayfuns @ 8-15 watts, clearos @ 8-13 watts and drippers @ 15-30 watts depending on the situation/liquid.

How about you?


Peace,

The Vamo outputs at 33 Hz, not MHz, that's why it's well known for its' noticeable "rattlesnake" effect. (More or less noticeable depending on the atomizer and volts/watts setting).

I measured the iStick at 48.5 Hz, (not MHz, I don't think my meter is even capable of measuring a frequency in the Mhz range), and the rattlesnake effect is noticeable at low wattage settings and some clearos, but not so much at higher watts. But if I put the same atomizer on the istick and then move it to a mech, it does feel smoother on the mech. I don't find the "rattlesnake" to be a big deal to me, it doesn't bother me while vaping, only if I start doing comparisons from one to the other am I aware of it.

Day 4 with the iStick. Can NOT put it down! It's small, it does a great job, and at the moment, it's all I'm using. I've got a 3 week old Hana that I'm planning on selling now, just need to find a buyer!

Agreed. Anyone who can hear any rattlesnaking in the MHz range has far better hearing than I...

That has got me off-balance!

Hertzs!

Forget the pets disgression! A normal human (if there are those left....) can hear that if any part of the APV or the atomizer resonates with it......

Obviously, I'm talking about non-filtered outputs, even if some part if the internal circuitry is actually oscillating at that low frequency and could, potentially, be heard....

Anyway, I'm really confused.... typical DC-DC regulators for other fields do oscillate in the kHz and MHz range, it's their way of improving yields of conversion. I guess that a different need arises here, and I'm mistakingly swapping the DC-DC oscillator converter (kHz to MHz) with the PWM pulse, before it's filtered, if applies, which seems to be, according to you, in the 33 to 800 Hz (VAMO through Provape's settings).

If that's the case, I'm marvelled because in case of bad filtering or any unavoidable resonance ....well, we'll hear it (the 'rattle-snake'?).



P.D.: I've just watched an Innokin i134 review from Phil Busardo and his oscilloscope output does not leave any clues unsolved.....48 Hz, period of 20,83 ms (i.e. they are oscillations per second, not thousands, not millions). My bad!

Mrs. Kodiak was looking over my shoulder reading your post and trying once again to fathom vapers. She simply shook here head, proclaimed us all "nutz" and returned to the other room. Thank you. I'm sure she initially came to me with something else I had to do but forgot what it was. (Or she thought I was surfing porn again.)

Heheheh... The rattlesnake effect. One of ECF's favorite subjects.

This is the best (short) explanation provided by p.opus in another thread on the subject.

I'm not a scientist, but I do own a 33 hz unfiltered device (Sigelei Zmax) and I do hear the rattle. Doesn't bother me much, but I do hear it!

I also own two rattle-free devices: a ProVari (800 Hz) and MVP2 (? Hz)--both filtered.

Give my regards to Mrs. Kodiak.

Which reminds me that I have things to do around the house.

But I bet she's happy that you are being nutz with your fellow vapers than she was when you smoked.

Thanks for the link. Seems pretty pricey for just the unit alone though. Are they reputable?

 

[Kryp2nite26]

Heres an equation for all you thread techies here....

iStick+1ohm parallel micro coil+20 watts+Kayfun Mini = BLISS!

Ecstatic to say the least. You should see what she's spending all the savings on. Don't tell her I got an iStick... she had that money budgeted for some throw pillows. (The kind that are too nice to "throw" and keep on the furniture).

well their in canada....i'm sure their o.k
