Evolv Technology Owners Discussion Thread

[retird]

Hello everyone I have a question that I was hoping someone in here could answer. I just received a dna30 box mod in a trade its my first box mod and my first dna and it is an evolv board but the builder of the box used a potentiometer instead of up/down buttons. Am I going to loose all of the options like stealth mode power lock and left/right mode? Or is there another way to access those options

You could use the on-board buttons if you can get to them....the on-board buttons are not to be pushed with the fingers however according to evolv...

The potentiometer closes the same circuits as the buttons do. You would need to follow the instructions to go into stealth, or left right mode and push the potentiometer in the appropriate direction. Does this potentiometer push down like a button? If it does, push it down and hold it for power lock mode. Same for coming out of power lock mode. This is the way the dial works on the Protovapor XPV.

Thanks for all the responses I haven't gotten it in the mail yet should be here today though and post some pics

 

[TheKiwi]

In case anyone is interested in THE definitive answer regarding the minimum firing voltage of the DNA20 and DNA30, stay tuned! Word from Brandon himself

 

[TheKiwi]

So here you go. The email exchanged copied and pasted in it's entirety, apart from edition out my name

So. Here's my email exchange with Brandon (if you're reading this then I'll just assume you know who he is )

Me:
I'm writing to enquire about certain technical aspects of the DNA chip, just for personal knowledge and my own use. I currently own 5 DNA 20 and 30 devices, and I guess I've always wondered if the chips actually have some sort of voltage down regulation? On a freshly charged battery, my mods typically cannot output anything lower than 3.7 to 3.9V before my resistance starts blinking. So yeap. Just wondering if it is because the DNA chip do not output voltages below the battery's current voltage, or there's something else in play. Hope to hear from someone soon!

Brandon:
Hi <my name lol>,
The DNA30 and 20 do not have step down (buck) capabilities. As your battery discharges, you'll be able to reach lower wattages. Our new (upcoming) products will have step down, also the Kick2 has step down.

Great question!

Thanks,

Hi Brandon,

Damn. Can't believe I'm getting a reply straight from you.

In any case, just wanna be clear in my understanding: when using a fresh battery, I wouldn't be able to select a wattage that requires the chip to output a voltage lower than the fresh battery's existing voltage. Eg firing an atty with a fresh battery, with a wattage setting that requires a voltage of say, 3.4 to 3.6 V. That's always been my understanding since my first dna20 mod, but I just wanna be absolutely sure.

Apologies if this sounds trivial; I figured you folks would be busy as hell but I just wanna make sure I nail down what I know about it. Have a 3rd dna30 mod incoming!

Brandon:
Hi <my name lol>,
Yes, the under load voltage is the limiting factor. So at a full charge (4.2v), you'll only be able to get down to about 3.9-ish volts. There is some loss across the circuit and it is looking at voltage under load.

Thanks,

My second email was kinda stupid and redundant given his first response (oh god... He's gonna think im some flaming idiot who couldn't understand simple English), but I had to be absolutely explicit in specifying the voltages we were talking about earlier.

So. That should pretty much put everything to rest.

P.s. If you actually have a fresh battery that's 3.5V under load, either something is reaaaally wrong with the cell, or it's nearing the end of it's lifespan.

There you have it...Way to go with the tenaciousness....And "There is some loss across the circuit" . is not in my opinion any type of down regulation....Not anymore than voltage drop on a mech would be considered some form of regulation.

Lol tenaciousness.. I haven't felt so guilty for wasting a man's time, and I felt so sorry for myself for sounding so dumb. But at least that's cleared up.

In any case, time to stop my DNA hoarding and wait for the newer chips! I know a lot of folks talk about how I can easily build according to my needs but ah, I would rather have a single build, and then be able to vape at the wattages I want whenever I wanna switch around yes, stubborn as a mule.

 

[EuroChris]

Thank you, Kiwi.


Also, don't feel bad. Brandon himself said it was a great question

If you haven't got the chance yet- Try the new Nautilus BVC system.... I'm very pleased and I'm stuck in MVP land so you, With your DNA hardware, Would be beyond happy- Dave

Haha I'm too cheap to buy atties where I hafta buy replacement heads for. Plus I have a healthy assortment of 20+ RTAs and 8 RDAs, so I can hardly justify buying a new tank unless it's like EERMAAAGERDDD AWESOME

Thank you for your efforts in getting clarification from Brandon. I think you have done Evolv a favor. The information directly impacts the user experience and, in my view, should have been explained in simple language in chip specs. I hope that in the future Evolv provides more consumer oriented information about their products.

There you have it...Way to go with the tenaciousness....And "There is some loss across the circuit" . is not in my opinion any type of down regulation.

Where did anyone claim it does down-regulation? The DNA regulates UP from whatever the minimum voltage at its output terminals is -- under load. That voltage is determined by the internal resistance of the battery, the resistance of the wiring and any connectors in the mod, and the "resistance" in the DNA itself. Remember that a boost regulator has a series diode, which intrinsically produces some voltage drop that's not load-dependent. Thus the voltage the DNA regulates up from is quite a bit lower than "battery voltage". It's also noticeably lower than what you'd get from the same battery firing the same coil in a good mech.

 

[BlueSnake]

The DNA30 is at the lower end of the range (~0.3v lower) and the DNA20 on the higher end (~0.5v). I have in my hand a DNA30 regulating 3.80v on a fresh battery as we speak. The DNAs do not have buck circuits however they do have a wider range than most people realize who have not actually tried to explore that range. You should try it sometime.

In your example, you were looking for a ~5 watt spread yet your upper wattage was only 23w. The proper thing to do is to increase the coil size to raise that upper wattage, since you have 7 watts of headroom. That places your lower wattage well within the voltage range of the chip, you lose no responsiveness and even gain some surface area.

Hola Evolvers
I have a question foer you modding guys... so I have a DNA20 mod with a strange novelty... somehow the ohm reading got stuck on 2.4!
Not really a big deal since it continues to regulate fine for the real ohm value, but kind of annoying.
Any ideas what could cause this? Perhaps easy fix?
Thanks in advance

To fix this you have to reset the board, if you have removable batteries, just take the battery out, wait 30 seconds then put them back in. If not you can run the batteries right down until it shuts off.

Wow, thanks!!!
Ok now I will work on running it down to the bitter end... good thing I got a new shiny yesterday which I like a lot

I dunno.... Don't think it'll be anywhere as low as 3.4 or 3.5 V.

Like Brandon himself said, taking into account inherent resistance of the circuitry, it'll only drop to 3.9ish. So there's that.

I have a DNA20 in my hand regulating at 3.35v fresh off the charger.

BTW anyone can email brandon, and some of us have talked to him personally about this topic.

Did he tell you something different than he said in his E-mail response? I'm curious....He doesn't strike me as the type of guy who waffles on the specs but I don't know him personally.
