hi ingerri, welcome...

sorta speaking over my pay grade, but :

some devices use - pulse width modulation (PWM) - to deliver power
by pulsing (on/off) is how it achieves the vw setting
(PWM) is measured in two ways
•MEAN
•RMS
the MVP doesn’t use pulse width modulation (it is a steady, regulated measured signal)
this is how I read up about it (so can’t say for positive) best I got :D
I don't suppose you happen to know what RMS stands for do you?

I will probably order an MVP20 soon as I like my MVP2. Long lasting battery built like a tank, and they seem to have corrected my only complaint about it with a spring loaded center pin.

Rotowoman I lived in the Greater New Orleans area until Katrina. Where in Louisiana are you located?
(just curious)

I live in the Lafayette area. I'm just outside the city limits of Lafayette, Broussard, and Youngsville. AND, I work at Grand Isle. How's that combination for you? :) My mother was from New Orleans, and I still have relatives out there somewhere. One of my uncles got wiped out again in Katrina and hasn't gone back. :mad: Poor thing, he was just too old to try to start over.

Are you still in the state?

We moved about 50 miles north, to the Picayune MS area. I still work in N.O. I just commute now.

Root Mean Square

Its kind of complicated and so far out side my wheel house that I just barely grasp it but it as a way of measuring and in this case controlling voltage. For our purposes using RMS means that the output signal comes out more as a smooth line without a lot of high (hot) peaks.

Or something like that :)

If you watch Phills review of the MVP2 you can see where he shows you on a scope the output signal of different devices and you can see how flat (smooth) the output is from the MVP. Very similar to the readings of a Prothingy.

hi draconianchaos, welcome to iTaste (MVP) land

RMS = Root Mean Squared. accurate means of taking a voltage measurement
MEAN (AVG) = the average of a number of samples in a given time
from my understanding , MEAN, is kinda meaningless (pun also intended) :D

I'm at 18 right now. Tomorrow I'm headed out to get some 24mg juice.
I was doing extremely well in the beginning, and just before Thanksgiving I had equipment issues (before the MVP) and I got stressed and went beserk.


OK, gotcha

think if you had a bottle or two at least, of 24mg you could switch

to vaping that when you reach for an analog kinda cig

keep at it, you sound as tho you're doing good ! :)

so am i understanding this correctly that the mvp20w runs in rms mode? i got an istick couple weeks ago and dont care for it. looking to get my first mvp :D

Root Mean Square... requires a MEAN value and actually requires you to know the time variances[frequency]... the MEAN value of a set of numbers that are all equal is the same as any one of those numbers... making the concept of RMS worthless. RMS is for outputs that have time variance. In AC, this would be the sine wave or other wave pattern... generally in DC this would relate to a wave pattern or to modulation (such as Pulse Width, which is actually a wave pattern with specific time variance). The MVP is a steady output voltage for all practical purposes, hence the output is the output.

Summary... when your output voltage is steady, the RMS and MEAN and AVERAGE are identical.

:p

I love the rich, hearty tobacco flavor – hell, I smoked analogs for over 40yrs
and I was no slouch, I smoked heavy and hard (I Liked It !) I don’t need to say how
it tastes with a good smoke and strong/hot cup of coffee - - or what it’s like to take
a heavy draw off a freshly lit one, after a swig of some good whiskey
maybe it was that-combo, that made it hard to stop…
- - -
so way back I stumbled on RY4, yum, I like that ! – probably why I started DIY
trying to make my own RY4 style juice, but I just couldn’t ever get it just right
a good rich tobacco, add some caramel and vanilla, never quite hit the mark for me...

then a bunch of weeks ago, whatever reason, I reversed the recipe
start with caramel, add tobacco - - whoa, there it is - I was going about this all wrong
caramel as my main base, then dress it up with tobacco & vanilla
my ADV, I found it, and do it cheap again & again ~ Happy New Year !!

It would be nice of you to make it Happy New Year for us too, by sharing your recipe :) I have an RY4 that makes me happy too, but still looking !

In other words you need to review electronics theory a bit more in order to comprehend what was just said there!

Abstract:
The rms (root-mean-square) value of various waveforms is determined without the use of calculus, which should be of benefit to the Technology student. These
waveforms include the half-wave rectified sinusoid, the quarter-wave rectified sinusoid, a waveform consisting of a dc voltage added to a sinusoid, the sum of two sinusoids, which may be periodic or aperiodic, a triangular wa veform, and a pulse train. Furthermore, in order to compute the rms value, the mean of the square
of a voltage must be determined over an observation time. A discussion of the importance of using the correct observation time is also provided.
