Let's Talk Hardware

Lori, I've got a similar problem with the 3.1 I just re-wicked last night. Either too much, but more likely not enough Rayon and can't keep up, or it's blocking the feed channels. Anyway, there is definitely something wrong - I'm getting a burnt taste on a 0.8 ohm ribbon coil @ 15watt. The previous tank same build & settings was fabulous!

Do you mean the 3.1 on the ZNA? I haven't tried any of my KFs on it yet. But it sure does seem to push more current somehow.

This build is 28 ga at 1.4 ohms. I built it so it would fire on the Provari. It doesn't cause an error on the Provari, it just isn't firing as well as it does on the ZNA. I've tested it on both to confirm. Both are running on 18490's and both have about the same charge on the batteries. It seems like volts on the Provari are not the same somehow as the same volts on the ZNA. Weird. But there must be some electro-mechanical reason for it. What you said about hertz may be part of the difference.

I haven't studied the DNA enough to know how they deliver the voltage. There were some mods that used PWM (some as an option) and they were quickly rejected. It is a technology that makes efficient use of the battery. They all had real low frequencies...33hz and it had the effect of burning your juice. Provari has always used PWM but they do it at super hertz levels so there isn't the dramatic voltage spikes like you get at 33hz. The result is more efficient use of the battery and it doesn't burn the juice. And another reason why they are $180.

Crank up the voltage on your Provari.

Yes - it's vaping great and tasting wonderful. It's loaded up with Serendipity. And it fires well on the Provari, though it's better on the ZNA. That part is weird. Even bumped up to 4.5 volts on the Provari it's not as warm or full as it is on the ZNA at 14 watts (4.3 volts). Anyone know if the Provari does some kind of power limiting or balancing?

Provari has a 3.5amp 15W limit right? Make sure you're not crossing one of those. It could be dumbing it down for you.

Also make sure your contacts on the Provari are clean. You may not be providing power efficiently.

I don't think the Provari dumbs down, Dust. I think it will shut down and give you an error code. I'm pretty sure the DNA will dumb down.

I just wonder if it is the function of the battery. Should probably use the same battery in each device...or is there an integrated battery in the ZNA?

1.4 ohms at 4.5 volts puts it at 14.5 watts. That approaches the Provari limit. Amps 3.2 so safe there.

David, any followup on your ream job?

Funny. As it turns out the center post is 1/16th. So all I really did was open the threaded end and the intake holes a little. It also cleaned it. I am getting a little more air so it's a win. I've read about people opening it more but not sure I'm going to do that. We'll see.

Interesting point. I bumped up the Provari to 4.6 volts. That's 3.29 amps, and 15.1 watts. The Provari still fires. At 4.7 volts, it won't fire. Being that close to the limit, the Provari might just not be able to provide power as efficiently, as you said. I clean the contacts regularly with 91% iso alcohol.

Both devices are run from the same batch of 4 AW IMR 18490 batteries, charged and rotated in use. I just switched out both to test on fresh batteries. Same result.

It's not a problem. I'm just happy to be able to use the Veritas on the Provari. I was curious about the difference between them.

I just tested both on fresh batteries. Both are running at 4.3 volts. (3.07 amps, 13.2 watts). Waited for the Veritas to cool, to remove cap or coil warmth as a factor. Same length of firing and draw. Same level of air on inhale, pulling on the draw.

The result is that the Provari takes longer for the vapor to get warm, and it's a lesser amount of vapor. The ZNA warms up faster and produces more vapor.

Could be voltage drop on the devices. Now I need to drink water and stop test vaping for a while.

The DNA30 has a 10 amp limit. A 12 amp battery is recommended.

Had some geek going on there. You have the right idea - just enjoy the experience.

Here's a way to think of it. You know those picture books where you flip through the pages real quick and it plays like a movie? Each subsequent picture is only slightly more motion-advanced than the previous? If you flip through the book slow it doesn't look as "real" as it does when you flip through it fast. In other words, the higher the frequency, the more real (sharper) it is. Hertz is the measure of voltage refresh in a e-cig. The higher the hertz, the more constant it acts even though it's anything but constant.

House of Hybrids is very safety conscious. These are the only batteries they recommend. Which batteries do you use for your DNA30?

The XPV came with a Sony VTC5.

Yes, the 3.1 on the ZNA. 0.8 ohm ribbon with rayon, ZNA is set to 14.8W and the Voltage readout is 3.7v and 75% charge on the bat. I had it up to 16W in the previous tank and Gaia was so delicious, I vaped it dry! Now with a new wick Gaia's tasting burnt.


Speaking hardware and electrical stuff - I was on here last night about 10ish and there was still a light rain coming down from a storm that had just come through. All of a sudden a hear a loud pop and caught a flash from the corner of my eye. Turned my head to look out the window and everything is dark as usual, can barely see the street through the foliage. Then FLASH, POP! Whoa, that is TOO close! Somewhere between the house and the pavilion.

I grab a flash light and head outside to take a look - just as I walk out the door there's another big flash in front of me and I hear the breaker pop at the main. Upon inspection and verified this morning I see one of the four lines going out to the pavilion is hanging loose in a tree. One of the branches is pushing the other lines over. I figure with all the wind we've had lately the branch had been rubbing against the wires till it finally wore through the insolation letting then shorted when the rain got in.

The electrician is coming out to fix it this morning.

 

[Iowa Gal]

Chak that doesn't sound good..glad you have someone coming to fix it

Ah, so you finally pulled the trigger on that - Pics when you get a chance, or it didn't happen.
