maybe its not annealed? I know someone bought some spiderwire fishing line that is "pure titanium" I would think that would be easy to find over on that side of the world maybe? But I can't say for sure how it works persnally...
I got some off etsy and some more off ebay -- totally different types of wire -- the one from ebay was really really thick and had a lot of oil or something that you need to wipe off -- and the stuff from etsy was super thin I still wipe this one down but don't notice as much residue coming off it! they both seem to work for temp control though
I think I am going to buy some of the sweet spot stuff myself just to get my hands on something that others are having good luck with -- then I'll know what i'm looking for when buying it in bulk...

I have a Windows XP version somewhere with shocking 77MB... You can make an image of it that hardly will go over 200MB... Where are you people getting 20gb-50gb?
I have virtual servers (Windows 2008 r2) that are less than 18gb in size (and plenty to spare). I can't see a simple XP install being bigger than that.
I haven't tried yet but I'm pretty sure you can run escribe with wine under Linux without needing a virtual box.

Doesn't escribe load a driver to connect to DNA200 devices? That could be an issue with trying to run it using wine under Linux.
r u using a mac running El Capitan?
i'm not running linux, i'm running mac OSX. i went to evolv forum n read that theres sm problem installing the latest VB on el capitan.
I have no idea what is going on with my charging. I used a couple different chargers. used the cable that was working. after 8 hours 3 boxes not fully charged again. darnit. it has to be something with the house wiring. I am going to call my buddy that is a sparky but not sure he wants to come all the way up here. we'll see. or is there something else that could be causing this? I am guessing no one else here has encountered something like this. the 18650 charger is working fine. as you could imagine this is a bit of an issue for me!
also, if a mac has 128gb I doubt that machine will run windows anyways. that is an old machine,no? that is the memory on an ipad now. why not get an ipad if you can. trust me you will enjoy it for other things too. I mainly prefer Linux but that is certainly not running escribe.

And, I reported the problem...
That was on my MBP. Also had the two (VB & El Capitan) on my Mac Air with same result. Downgraded the Air to Yosemite. Worked for a while, then USB glitches.
Reports were that VB 5.06 screwed the pooch. 5.08 and 5.10 no better.
So, I am limping along on my XP box until there is a native Mac port. Could I try another downgrade and Boot Camp? Yes.
But at this point it's not worth the trouble...unless I hear/see someone report success since I can do everything I need in XP except screen captures. Report is there is an XP fix for its screen anomalies.
I can wait...
thats what i read for evolv's mac forum, few ppl have success with el capitan. so can u still configure ur dna200 thru yosemite? i'm thinking if downgrading to yoshemite can solved the problem, i might do so for the time being.
anyway, i've email evolv regarding abt a mac support, here's what they replied"
View attachment 508652
The comment I bolded was incorrect. The board does appear to continue with Refinement after about 5 minutes however it still persists in Power mode ----F incorrectly even after Refinement has been engaged.
I use a mac and have no issues...you do need to use virtual box or VM fusion.
r u using El Capitan, i went to Evolv forum n read that there's many problems letting ur mac recognise the dna200 chip.
Mac Suppport - DNA 200 Early Adopters Forum
So I am doing a random test.
so I got 3 old blue samsung 25r2s. they are about 4 to 5 months old. I got two yellow LGs. I forgot the name. the 2500mah ones. and then I got two green 25r5s.
the old blues are like messed up and I don't want to use them anymore until I rewrap them.
So I was curious. People always yell about using married batteries and how they have to be the same brand.
Well I decided. oh hey lets mix up two of the yellow LGs with a 25r5.
oooh scandalous right.
so I did the battery analyzer and my result went from 21,5ish wh to 24,7wh. so a decent gain. but I was more surprised to see that even though I was mixing brands the voltage drop was damn near identical. and the end result was that the green samsung's voltage was 0,05 volts lower than the yellows.
so honestly I see no negatives about mixing those three batteries up. I gained battery life(theoretically) the voltage drop is damn near the same and the voltages levels at the 3 volt cutoff are pretty much the same.

I am not using El Capitan for various reasons, but folks using it have had success with VM Fusion.
omg.. u r the one who posted a tutorial about how to install VB on a mac at evolv forum?
if i were to downgrade to Yosemite n followed ur tutorial, will there be any success of connecting my mac to a dna device?
Seeing a lot of talk about charging lately so figured I should bring up some concerns and questions from posts I've seen with the charging of these devices. Since the first week of having mine and seeing it pull almost 1 Amp through my PC USB a couple times it's been a concern and I always watch it closely when charging. Understanding that these boards are supposed to be limited to 500mA when connected to a PC I don't really understand how this can be.
A few examples I'll post of some others charging above the stated and some failures that may be related.
This poster was charging at 1.14 A and found a missing component on the board.
Battery not charging - DNA 200 Early Adopters Forum
This is mine and to the best of my knowledge there is nothing wrong with the board. Note that each cell is at 4.2V but pulling almost 1 Amp.
Board fried while mod was connected to PC overnight - DNA 200 Early Adopters Forum
This is the highest current being pulled that I've seen captured at 3.082 amps, cells initially balanced then became imbalanced

This poster posted his USB Bus was fried when connecting the device to his PC.
Charging circuit blew my motherboard/USB/Ethernet rail - DNA 200 Early Adopters Forum
"I was attempting to program a DNA 200 Chip today and upon plugging it into my PC the PC turned off I smelled a faint burning smell and upon turning the machine back on found my USB2 Bus / Ethernet controller to be fried. I yelled like a psycho and replaced the chip with a working one then set the bad chip aside for testing, pretty ...... off about the PC btw."
This poster reports his device caused his PC to flag USB Over Current and reboot and then temporarily crash his USB group.
Tugboat DNA 200 completely dead. - DNA 200 Early Adopters Forum
"Today mid puff my tugboat DNA 200 stopped working. No matter what I do it will not turn on. When I got home I tried hooking it up to Escribe. When it was plugged in to the USB as my computer booted I got a USB over current status. And my PC rebooted after 15 seconds. The next try I booted my computer up and then plugged it into the usb. Once it was plugged in it killed that group of USB plugs until I rebooted my computer. When I plug in my Vaporshark DNA 200 everything is fine and it connects to escribe. Has anyone seen any issues like this? And any possible solutions?"
There are more similar posts some reporting dead boards while charging and some dying shortly after charging. Lot of imbalanced cells or balanced and then they become imbalanced which seems very odd to have this many reports of bad cells.
I don't see anything in the data sheet that indicates there's USB Over Current Protection.
So this makes me wonder do these boards have USB Over Current Protection?
Shouldn't they if they don't?
If they do what could explain these examples?
If they do is it only mechanical in nature? As in by utilizing only the electronic components?
Couldn't there be USB Over Current Protection logic programmed into the firmware? I don't think there is since mine appears to work as designed and some of the others appear the CPU is functioning and communicating via USB with the PC and Escribe but no software restrictions appeared to be activated when they were charging above 500mA while connected to PC.
What about circuit isolation, couldn't there be isolation so if a component failure does occur it could be rendered inoperable or as an open circuit so as not pull more current than it was designed for and potentially damage the source charging power source?
Has anyone else had concerns with these reports? Not so much for the battery packs as I know they're well capable of taking higher charge but for the PC's and the Boards charging circuit.
These concerns make me hesitant to connect to my PC so I usually try to charge with an external charger. But when connecting to my PC I always monitor it very closely to make sure it's not pulling more amperage than it should. My electronics knowledge is mostly forgotten so I have a lot of questions & concerns. Hopefully one of you EE type can answer some of these questions.

The supply should foldback voltage if excessive current is drawn. If the supply can't protect itself, it sort of deserves to die. What does the supply do if the 10c production cost USB cable shorts -- start a fire? Bad design on the PC end, plain and simple.
For the issue of why a board connected to a PC USB interface port would draw current in excess of 500 mA, that is a malfunction. Can't say where the problem is but clearly it is not supposed to do that.
Well, thank you all for your chatter over the past day or so. As mentioned, I was first to observe the conflict with VirtualBox and OSX El Capitan. Prior to that conflict I had a working set up with eScribe with VB and Yosemite.
After installing The El Capitan I lost the ability to work on the MAC (Air & MBP).
Because of your chatter I considered either or both VM Fusion or Parallels. I was partial against Parallels coz I had it installed on a previous MBP, though thoroughly UNCONVINCED.
First to install tonight, for no particular reason was Parallels. Thought long about removing VBox and my Windows 10 installation but resisted the urge.
Lo and behold, Parallels "saw" my already installed Windows 10, configured it, and completed the setup without any assistance from me.
Downloaded and installed eScribe. Gave permission for Windows to connect the USB. Voila!!!!! eScribe recognized all three of my 200's [Reuleaux, Vapor Shark, and, Lavabox].
I am back in business! With GREAT screen redraw. XP be dammid!
Remarkably I see different performance among the devices: Watts/Temperature Limit relationship. Will observe for a while before saying anything definitive...
Again, thanks for the chatter.
