Hi guys :)

I think it would be a nice idea if one of you who owns
some more of Imeos resistant wire can provide a chart
who compares the centimer with the resulting ohm so
id would be easier for everyone without a multimeter.

Without the long awaiting VV mod we still have the problem
that we do not can give constant voltage to the atty but that
problem we already have yet with other unregulated equipment
so anyway...

It think it would be nice to have a list of values who depend on
off all possible compbinations of voltage we can get by combining
the diferent battery type.

As Vassili wrote me there are the following possible:

3,7V, 6V, 6,4V, 7,2V, 7,4V and maybe we should also add 3,3V

I know that the other maybe like it with a little bit more resistant
the other with less but just to have a recommended range of the
the guys who vaping for a long time.


Thanks in advance
Spiralnebel :)

I don't really know what I'm doing yet, but both that I've made so far are about 1.6 ohm and about half an inch. I need to make some more later to crystallize the process, and I'll try to get more precise measurements and post them later. I bet there's a formula you could use that would predate multimeters. But I wouldn't rely on it if I were you. Just a wing it until you have your multimeter in hand. ;)

32 Gage Nichrome is 10.6 ohms per foot
34 Gage Nichrome is 17 Ohms per foot

so, for 32 ga, 10.6 ohms/12 = 0.8833 ohms per inch. in order to make a coil that is 1.5 ohms you need a R wire that is 1.69 inches long.

for 34 ga, 17 ohms/12 = 1.4166 ohms per inch. In order to make a coil that is 1.5 ohms you need a R wire that is 1.06 inches long.

Now, that is the length of the R wire that is between the 2x NR wires.

Spiralnebel,

As dspin has stated in a round about way, the advanced toys require some advanced tools.

A reasonable multimeter can be acquired for under $50US.. You'll find it invaluable in the following situations:

1) The vape seems cool, are my batts charged?
2) Is my thread lube adding resistance?
3) My battery says it's charged, is it?
4) My atty doesn't fire, does it have continuity?
5) Where do I add the non-restance wire to get exactly X ohms?
6) is my spring adding resistance?

These are all ( i think ) all the things I've currently come across and tested, I'm sure there are more.

You can probably get by with just measurements, but there are many variables at play, including the actual wire. The best way to get to that perfect vape is accounting for the variables and measuring what you can.

I have a pair of DMM's but am still interested in the calculations. I am sure it was listed somewhere but can someone tell me what gauge was sent with the Ody's?

Thanks!

You know I don't recall Imeo specifying where he got the Ody mats or specs on them. Hopefully he will let us know after his much deserved Christmas break.

Thanks guys :)

At the time i opened this topic i already ordered a multimeter
but i just want to make it as easy as possible to other members
just not to waste wick and wire for such experiments.
In fact not all of us have enough material at home yet so why
dont just provide such a list ;)

Anyway...

:D My multimeter arrived today and know i would like to ask if someone
would be so kind to explain in some simple words how to handle it

Sorry for that but the manual who comes with it is just a piece of crap
and i'm sure i'm not the only guy who never used such a device before.

I attached a picture of the device i bought so it would be cool if you can
tell me where to set the wheel and where to put the red and black cable
to be able to 1) measure the ohm and 2) measure the power of my batteries.

Thanks in advance and a HAPPY NEW YEAR to all of you! :)

:) Nice - Thanks

With the wheel on 200, so at 6 a clock its more accurate
cause i can see 2,2 ohm at one carto and not just 2

and how to measure the volt of my batteries?

V=20
IIRC using the meter set to ohms on you battery is not good, so make sure you switch over first

Thanks ;)

Now i know why it made a sound when i tried it ^^

I read when i want to measure the resistance
i need to check first the resistance of the red
and black cable by holding one to the other
but on 200 i do not get a result cause the value
always jumps up and down.

Where to set for this?
Or does this do not must done at every device?

Just touch the leads together and pinch them between your fingers. It should level off to 00.0 but more realistic might be 00.3
