Yes that is where I thought you were talking about. Most of my machines have XP installed on them (still my favorite Windows version) and I don't think I ever saw that on XP or older. And I can't ever recall going into Windows 7/8 USB properties for anything.

Are those voltage readings from EScribe or from a multimeter? As when the DNA is working flawlessly, I trust its cell voltages. But if I suspect something is wrong with the DNA, even the slightest, I wouldn't trust those readings in a second.

That is very strange about saying there is/was a Control Panel applet that controls the limit of USB ports. I have been using Windows since '93 and many other OS before that and I must have more than two dozen Windows machines here. And only Vista and Windows 10 I haven't ran. But the rest from Windows 3.1 and up I have. And I don't ever recall that applet. I am not saying it wasn't there, I just never ran across it. Sounds like it is one of those manufacture dependent drivers to me. As for better USB cables... those were using the very same USB cables. I can get 2A from them without a problem. I do have one data power cable that came with one of my cell phones that I never saw anything higher than 120ma going through it. I have been meaning to check those wires for resistance because they must be quite high. The data side works quite well though.

I don't think most computers restrict ports to 500ma. At least the many that I have seen don't. Like this machine has four USB2 ports. And I have seen over 900ma being drawn over one port. I think most machines are like this one and supplies 2A (500ma times the USB ports) total. But when you connect up a DNA, it always charges at 500ma. While my USB TV tuners, USB DVD drives, etc. will draw 900ma or more from these same individual port. My two XTAR VC4 battery chargers act very similar to the DNAs (like most devices that charge through the USB). Although my VC4s will only draw about 150ma max from the USB from this machine. Yet connect them up to XTAR's own USB power adapter and it draws 2A max.

That is very strange. I have a power only USB cable here and plug that in this machine's USB port and the Triade is only drawing 400ma. Plug the same Triade and cable into a XTAR's USB power adapter (5v @ 2.1A) and the Triade draws 800ma. Yet plug in my USB TV tuner in the same USB port on this computer and it draws 900ma.

There are DNA200 mods out there with reverse battery protection. Well at least one model called a HCigar VT133. I liked the first one so much, I bought three more of them.

Are you sure it has to do with a data path? My XTAR VC4 battery chargers for example, also limits the current draw depending on what you plug the USB into (doesn't use the data connection). There are tons of devices that all work similar. And from observation, I think they operate by monitoring the USB voltage. The more current you draw, the lower the voltage will be on most supplies (including computers, wall chargers, etc). And I think they monitor the voltage and only draw as much as to keep the voltage high enough.

(Absolute) Max Input Voltage /topic/65655-topic/

If I recall correctly, I believe it was James who said 16V max. So you should be fine.

Nice job Jentz!

Oh sorry, that is the wrong one.

Update Instructions: Here is the "official" settings file created by Evolv for the Lost Vape EFusion DNA200. This file contains the complete results of the Battery Test, Mod Resistance offset, and Case Analyzer. Also included are Titanium, and SS profiles. This same file has been provided to Lost Vape and will be coming on all new completed production mods.

I bought 10 DNA200 mods in the last 6 months and I'll probably buy another 10 DNA200 mods in the next 6 months. And I don't need any updates. The DNA200 is the best regulated device out there and nothing else comes close. So I don't think Evolv has anything to worry about. There isn't even any competition yet.

Oh that was on a Crown RBA using a single 3mmID Ni200 28g coil.

Yes like Scarab and VapingBad already stated. In EScribe, just uncheck Temperature-Dominant for the Profiles (General tab) you want Wattage displayed in big digits on the right. Don't forget to Upload Settings to Device.

Preheat you can set higher than the wattage (like 50% higher) and 1 or 2 seconds should be a good starting point. How hard? Just use the middle of the slider right now.

What does the graph look like with power, temperature, and live ohms selected? It should look something like this:

It is fine to charge DNAs with the USB. It is just those Chinese chipsets that you shouldn't charge by USB.

The ohms should stay the same on the screen. That is because that is cold ohms and that should stay the same. In EScribe though, the Atomizer Analyzer will show live ohms (only updates when not firing). And you can see live ohms (while firing only) in the Device Monitor.

Doesn't Apple demand a cut of the profits for anything that is Mac compatible?

Oh in my example above, I forgot to tell you the correct answer. It is .006087 change per 1ºC. Which is the same as your TCR value.

Sure, but the TFR graph isn't truly linear. So you must take an average of it. So you need to know how much the resistance changes per 1ºC of temperature change. You should take an average throughout the vaping range. Although if the TFR graph is pretty linear without curves, they all should be virtually the same anyway. Take this Ni200 csv file for example. "Temperature (degF)","Electrical Resistivity" -58,0.58 68,1 212,1.48 302,1.78 392,2.08 482,2.38 572,2.68 800,3.44 Oh that csv file is in Fahrenheit. That just complicates matters, let's use Centigrade one... Hmm... I don't have one. Anyway convert to Centigrade. That second value is how much the resistance changes from 20ºC. Like at 800ºF it changes the resistance by 3.44 times from cold resistance (68ºF). So from any two points you can calculate how much change per 1ºC. And that is your TCR value. Stream Engine will automatically will tell you the TCR if that is where you got the csv file from anyway.

I thought you might think I was crazy after I posted it.

Well are you going to use this single coil build SS on a Kayfun? And what size wire are you planning to use?

I know how to do it on the DNA200, as I don't have a DNA75. But with Temperature Dominant, you select show temperature and it shows Wattage.
