VIR official

[FogNL]

I'm surprised that you're planning to make VIR available to other modders too Imeo. Good news although personally, I won't be using or buying VIR in anything else than a GG device.

Is the current VIR a co-development/production with Dicodes?

 

[imeothanasis]

I am planning to give to modders but much later Fog. But I am happy that you will only buy GG devices with VIR on them

VIR has nothing to do with Dicodes. I dont really know what they are making.

What makes you think a DNA40 can't use titanium or stainless steel?

With temperature control....I don't think so. A few of the members here tried it with SS wire and they said it didn't work in temperature control mode.

I can assure you the DNA40 works just fine in temperature mode with pure titanium (Grade 1). I have not tried the titanium alloy that ESG sells. I don't see any reason to. My original objections to pure titanium were the oxide formation at high temperatures (which is not an issue when limiting temperature) and the relatively low resistance of the coils (which the DNA40 handles quite gracefully because it's nowhere near as low as the recommended Ni200 anyway).

I have not yet had a chance to try stainless steel wire yet because I've been away from home the past week, but will very shortly; I received spools of 26, 28, and 30 gage annealed 304 while I was gone.

Also screen doesnt offer anything on VIR. The only it offers is to make your life more difficult because without a led you have to always check the screen to see why your e-cig doesnt work when it stops because of the temperature or because of the battery, when on VIR you know this info via LED that blinks in front of your eyes. Also VIR doesnt need you to check your resistance via a screen because it auto detect wires, so this info is useless on VIR.

So it's useless to see the state-of-charge of your battery at a glance? And it's useless to see what your mod thinks the resistance of a coil is, compared to what it theoretically should be based on a coil calculator? I find both of these very useful.

Ros, maybe you are a little confused my friend. Dna works only with nickel on temperature control, that is a very bad choice by the way for health reasons.
Your tests were made on vw mode. I suppose that you made a mistake and you put it on vw

I think he is implying that he has a dna40 and tested it with titanium grade 1 and it worked for him.

 

[imeothanasis]

I am sorry that I will say this Ros but you dont read all my posts. If you want to be an active member here, you have to read everything I assume.
I have already said that the only you need to know on a screen is the voltage of the battery. But even this, is not very useful on VIR because it carries "the battery voltage auto detection" and adjusts the battery to atomizer needs, so you can vape it until battery reaches 3,3 volts.
As for the resistance, I have said many times and on my videos too that resistance is irrelevant because on VIR all resistances vape the same

 

[imeothanasis]

on vw mode Dirts? Yes it works. But no one bought a temperature control device to use it as vw

 

[Dirts]

Actually i think he means in temperature mode.

But Evolv did not mention using titanium in DNA40 so its possible that the dna40 is detecting the titanium wire as a nickel wire so the temperature limiting might not be accurate maybe because its powering the coil as nickel....

Someone should test dna40 with temperature using titanium wire...IF it does work in temperature mode...

I dont know much about temperature testing. Sounds like a pbusardo job.

 

[imeothanasis]

it simply doesnt work Dirts. It maybe vapes for a while but the screen will show 200 and in reality it will be 300 or 100 or....... Thats not temperature control of course. If we are not accurate at +-5 degrees on a control like this, our devices are useless.
A temperature control device has to reach the temperature in less than 0,5 second and to keep it to this level. If a device reaches the temperature in more than 1-2 seconds then it acts like a mechanical device and nothing more.

 

[soulseek]

In an ideal world, of course you would go with a screen. The point is what sacrifices do you need to make right now to get it? I can give you many examples from cars to mobile phones and even to garbage bins.

Also could people post images of the devices they're using the DNA40 on? I'd love to see them.

The DNA40 absolutely DOES work in temperature mode with titanium. I've been vaping it that way for more than 10 days. Of course the screen doesn't show the actual temperature, because the temperature coefficient of titanium is less than nickel and the display is calibrated for nickel. But it definitely does regulate temperature and prevents juice or wick from burning with a titanium coil. So instead of setting to for example 430°F (~220°C) I set it to 340°F (~170°C).

Oh, and if +/-5 degrees accuracy is necessary, then why are the steps in VIR 20 degrees? Not long ago, you said:

5 celsious degrees doesnt make any difference

A temperature control device has to reach the temperature in less than 0,5 second and to keep it to this level. If a device reaches the temperature in more than 1-2 seconds then it acts like a mechanical device and nothing more.

How fast your set temperature is reached depends (among other things) on the mass of the coil and how much power you can apply. So how much power can the VIR apply?

Moreover, whether your temperature set point can be reached at all depends on how far above the boiling point of your liquid that setpoint is (assuming of course that your wick is up to the task of keeping your coil wet).

 

[imeothanasis]

if dna works with nickel then it simply doesnt work with any other wire Ros. So if you put it on 170 with any other wire then you dont have any control. You just vape as in a mechanical mode. You simply dont know at what temperature you vape. If things where like you say, then I could say to people that VIR works with nickel and in fact with any available wire in the market, something that would be a lie of course and it would be silly for me to say something like that. People are not stupid if you agree and it would be bad for them to tell them whatever it comes to our minds.

VIR has an accurancy of +-5 celsious degrees, something irrelevant with steps. I could go per 50 steps but I always have to be accurate on what customers vape. I dont see a connection between accuracy and steps. Steps are made to give to customer a different vape and accuracy is made to give to the customer the ability to avoid toxics on liquids, something that is more important than anything else. Dont confuse the pleasure with healthy vaping. If temperature is not accurate then you will vape toxics and a device like this would be useless.

Of course temperature depends on the mass of the coil as you said. So VIR can give up to 40 watts to reach the right temperature as quick as possible. But its not a matter of power on VIR, its a matter of construction. Dna cant do that because its made like this, when VIR is made in a different way. I think Brandon said that already.

Speed of temperature point doesnt depend on how far above the boiling point of your liquid that setpoint is. At least on VIR. Maybe it depends on dna but not on VIR. It depends only on how much liquid your coil carries at that time.

 

[soulseek]

He's said many times 25W on a single battery, 35W stacked.

Still curiously waiting for a photo of your DNA40 device.

I also find it quite funny that you're making a big fuss about the importance of a display and what information that brings with it but then you admit that you're vaping on a device that doesn't actually tell you what temperature you're on; it's only a guess.

 

[imeothanasis]

I made VIR work at 40 watts now Seek

 

[Rossum]

He's said many times 25W on a single battery, 35W stacked.

So I guess it's strictly a buck regulator?

Still curiously waiting for a photo of your DNA40 device.

Well, I thought it would be inappropriate here, but since you're being rather insistent about it,

Pre-construction:

All wired up:

Test firing:

Nickel coil:

24 gauge titanium coil:

Twisted 3x 30 gauge titanium coil:

 

[imeothanasis]

So I guess it's strictly a buck regulator?

How did you came to that conclusion Ros? Anyway its a wrong conclusion of course. VIR boosts and back batteries. It was made like this a long time ago, before dna put this feature on dna40. VIR also vapes 2x3 volt batteries, something that no other device does.

As for the pics you just posted, VIR is wireless and has nothing to do with all these connections and wires and glues and plastics and ........... all this stuff.
Also, dont forget that VIR is less than half of dna or the devices they carry it. As for the size of the mod on your pics, I dont want to comment

From what I've been reading it's not a guess, just a conversion taking into the account the difference between nickel and titanium properties. The difference between the two isn't enough to kick the DNA out of temperature protection mode either supposedly, unlike when using kanthal.
If true, and Evolv has half a brain at least, they'll modify/add into their software the ability to use wires like that. lol

I'm watching both VIR and DNA with interest to see how the tech matures, as temperature controlled/moderated vaping is very interesting to me.

 

[Rossum]

if dna works with nickel then it simply doesnt work with any other wire Ros.

I guess it depends on how you define "works". Shows "correct" temperature on display? No. Vapes well and regulates temperature? Yes.

So if you put it on 170 then you dont have any control. You just vape as in a mechanical mode.

No sir, that's incorrect. If I use a mechanical or even a VV or VW regulated mod and I let the wick go dry, I have a burnt wick. DNA40 with nickel or titanium wire, set to an appropriate temperature will not burn the wick.

You simply dont know at what temperature you vape.

Nor do I need to. Start with a low setting, like 250F. Fire it. No vapor. Increase temperature setting until it begins to produce vapor with a known juice. Keep increasing until it produces satisfying, good tasting vapor. Verify that at this setting, it does not burn a dry wick. That's good enough for me, because if it doesn't burn a dry cotton or rayon wick, it doesn't get hot enough to produce toxic substances from e-liquid either.

Of course temperature depends on the mass of the coil as you said. So VIR can give up to 40 watts

Does 40 watts require stacked batteries? Many people do not think stacking batteries is very safe at all. Personally, I think it's OK, if (and only if!) you keep batteries in pairs all the time, even during charging, but will people actually do that?

Hi Imeo, I think the VIR is great and I wouldn't change it in anyway. I just thought if you offered a second chip that had a screen and usb connection you could directly compete with the DNA40.
