Evolv Technology Owners Discussion Thread

[retird]

Well, if the poster in this FT thread is truthful, it seems that the EZDNAs are in fact using genuine Evolv DNAs (post #6 is quoting an email from Brandon):

well i'll be damned... a china tube mod with genuine evolv dna30: FastTech Forums

Interesting link you got there.... One sbody's web site shows the Vapor Shark as dna and says it goes to an exclusive sales agent in the US. DNA E Cigarette Battery. I briefly looked at all the devices they listed on this site and saw no EZDNA designation nor a device looking like either one....

Next google : Product - E cig mod - ecigs,electronic cigarettes,electronic cigs,electronic cigarette,wholesale ecigs,ecigs suppliers,ecigs manufacturer,electronic cigarettes manufacturer Sbody web site also.... shows both devices with descriptions saying original DNA PCB..

So it may very well be that both these are brother/sister DNA devices.. IMO

It gets even more interesting. S-Body claims that they make the Vaporshark:

DNA E Cigarette Battery

Well that's interesting and could very well be true. When you think about what it takes to start a manufacturing company in the U.S.

OOh ooh a thread like this!

Um. I'm not sure if this has been answered elsewhere, but if anyone could explain to me why the evolv chips don't do down regulation of voltage, I would appreciate it

I bugs me a little because I have a bunch of builds at 0.7 or 0.8 and while I vape them mostly at 23 watts just fine, I do wish I could drop down to something like 15 to 18 watts for my morning vapes.

ETA: feel free to ignore this if this isn't the intent of the discussion thread.

It's all in the chipset design and the resistance of your build I think. Like most chipsets they are designed to operate within given specifications.

Per data sheet: Too low power setting: The DNA 30D puts out a minimum of 4 volts. With low power settings (7 to 8 watts) and low resistance atomizers (below 2 ohms) the DNA will sometimes be unable to provide a low enough power output to be power regulating. If this is the case, the Ohms display will be flashing. The device will still operate.

Yep..... VS verified S-body makes the VS for them..

Ah ah right. I guess I was looking for both a technical explanation as well as a user experience perspective, since I actually think that down regulation would be a very popular feature.

I guess where I was coming from was when I watched PBusardo's interview with mike from House of Hybrid, and he basically explained that reverse battery protection was deliberately left out of the chip design due to the feature of the chip which allows the chip to "read into" the battery to monitor battery health. He explained that reverse battery protection are typically implemented via the use of diodes in the chip circuitry. However the use of diodes would then render the chip unable to read into the battery.

So. Yeap. I guess I was just more interested in the technical explanation. I hope I'm making sense! Just genuinely curious about all these fancy stuff since I design certain weapons systems and their electronics.

Hey.... Weapon systems ? ... please aim them elsewhere...LOL The sub-ohm seems to be all the rage at this time and really begs for regulation below 4 volts and the need for more wattage/amperage.

The technical talk may come as others read your post (way above my pay grade) ... I too am intrigued by the newer technology coming out which possibly regulates at lower voltage settings for sub-ohm coils. Amazing how e-cig technology has progressed from it's infancy now to it's childhood (remembering legacy buck devices and boost devices where neither were joined in marriage).

From a recent Innokin news release the SVD2.0 features a maximum output power of 20W and a minimum resistance of .5ohm. The Evolv DNA Experience™micro chip also has the ability to step-down power which gives sub-ohm vapers a wider precise range of usable power levels. Will be interesting to see when it arrives.

When the DNA 20 was new I was whining pitifully to Drew at nHaler about it having no buck circuit. He said something about Brandon mentioning heat sink and the size of the chip. This made not a lick of sense to me but I'm an electronics idiot so I didn't pursue the subject further.

You don't need a subohm build to get a warm vape from the DNA 30. A .7 build on a mechanical putting out 3.7 volts generates 19.56 watts. The voltage of a 1.1Ω coil is is within the DNA 30's regulated range between 15–30 watts. A 2.3Ω coil is within the DNA 30's regulated range between 7–29 watts.

I agree. My 1.3 ohm coil in the KFL works at 20 watts. But I'm using .6 ribbon wire.

Yep.... kinda confusing.... I've slept many times since then and don't recall all the talk during that time....I would think the chipset not being designs as a buck/boost would be the main player....

Evolve's going to need to get something out soon to catch up to the YIHi SX350 which has booth boost and buck circuits. There are a few devices on the market already and the chip has been extremely popular with modders.

I had a short conversation with Brandon a while back about getting the batteries in my Darwin replaced and he commented that he knew of the SX. He said they were working on a few things also and that he welcomed healthy competition.

Likely for simplicity of the chip design, which allows a smaller package, lower cost, and higher efficiency. Also there is some context, when the DNA20 was designed, no one was even dreaming of using 20 watts, so the idea of needing low voltage regulation seemed counter to the intent of the device -- high power regulated vaping.

Now as long as you understand it, you understand that subohm is neither necessary nor really desirable with a chip with high voltage capability like the DNAs. So build the coils at a higher resistance to get the wattage range you want.

Also keep in mind that the 4 volt lower limit is not actually true, I've had DNA20s down to below 3.0v and DNA30s down below 3.2v.

You said it well..... using the dna within it's limitations and all is well.....3.0 ohm coils for me so full range of wattage could be used but anything over 10 watts is over kill for me... lol....

But could you get 3.2v when you WANTED to on a fresh battery?

 

[TheKiwi]

Lol yeah exactly that. The DNA chip only let's you go as low as the battery's current voltage

 

[dr g]

Generally you will see no less than 3.4-3.5v on a full battery, so build accordingly.

Not true. That's the whole point of what I posted.
