  3. Which is more accurate a TCR number or CSV file?

    [QUOTE=jazzvaper]@mactavish I did watched the entire video. And had watched his video on the Hotcig, which after mine died I returned for a COMPLETE refund.

    I was asking "watcher64". Assuming he tests exactly the same with his temperature probe, he does publish different temperature results with TCR Versus CSV inputs. Guess I'm going to have to write and bother the SteamEngine author again, maybe it's the holidays, but surprised no official response from Evolv, they really need to either hire more help, or get some product experienced moderators here to help out. This entire forum is getting like the Apple site, just end users helping each other if they can, and little input from the source![/QUOTE]

     

    My thoughts would be that the CSV is of course not as accurate for some reason, and that could be steam engine, or it could be how escribe plots the points.  If you look when using the TCR, I checked with TI only BTW, the base resistance and the top end are different, which could throw the whole thing out of wack.

    But honestly, I could care less about "exact" numbers, if it vapes well, is not burning, not melting my face off, then then I'm not overly worried about it.

    (on another note, is it possible that, when using a csv to plot the points , and adding this "checking" the chip just does not keep up.)

  8. Temp Control and Stainless Steel

    Don't get me wrong , I am sure there is a difference ..

    BUT, the DNA200 is not a magical device that can break the laws of physics ..

     

    You have a chip that has to look at the temp setting, look at the current ohms, calculate the temp, then reset the voltage/wattage to achieve the required setting.

    Now taking into account, the switching on and off of the power, the adjustment of the power and the fact that there is going to be heat loss/gain in that moment, unless they have magically managed to throw a super fast cpu, super fast transistors, switches, and voltage regulators on the board (which I know is not the case), the chances of getting super accurate temps is just not going to happen.

     

    And yes there are different types of SS, but they all fall around the same variances, some a little higher and some a little lower, but, with this type of TC the variance in ohms is what determines how accurate it is.  The smaller the variance the less accurate it can physically be.

     

    Again just my 0.02 and my personal opinion.

  9. can the firmware be opensourced at some point?

    Too much proprietary stuff in the source to open it up. They're not going to hand over all their secret sauce to every company looking to clone the board. It would be awesome if they continue to open up more customization in escribe though.



    I don't think cloners are truly worried about that..  They cloned the DNA30's and 40's without open sourced firmware.  If it is going to be cloned it will be regardless of open or closed source.

    To be honest I don't see how SS wire works at all for TC, just my opinion, but I think you guys are fooling yourselves.  The science just does not support SS being any good for TC.

    NI 200 has a base resistance at minimum temp of .62 and at max of 3.52 that gives you 2.9 to play with to calculate the temp.
    TI has a base resistance at minimum temp of .61 and at max of 2.45 giving you 1.84 in between to calculate.

    SS on average has only 0.45 ohms of difference between min and max, that is a very slight amount to be able to calculate and maintain any accurate temps.

    You can see this in device monitor as constant spikes above and below.

    Just my .02

  12. Escribe on Linux?

    in EScribe, Software and Firmware

    Posted

    Escribe only natively runs on Windows, without knowledge of how to setup a virtual machine on linux it is not going to happen.

    If you are still interested in making it happen, look up a program called VirtualBox, it will allow you to setup a Windows machine "inside" the linux os ..

    OR Optionally

    You could just install windows on the laptop ..

  16. eeek!! Help Installing Escribe with Chromebook

    in EScribe, Software and Firmware

    Posted

    That is an ARM style cpu, I seriously doubt you are going to get escribe to run on a chromebook.

     

    I don't think you are going to find any Windows virtual machine software for it, as it runs chromium.  Also being a ARM processor throws another wrench in the works.

     

    Escribe needs Windows(and MAC in the future), or some type of virtual machine, but even with virtual machines there are issues ..

  25. Feature Request: Suggestion "NO AUTO DOWNLOAD SETTINGS OPTION"

    in EScribe, Software and Firmware

    Posted

    Sorry if this has been asked or suggested before ..

    It is just a minor annoyance, that you spend time working on settings, and MAYBE forget to save them and the box downloads settings when you plug it in.

    At least in my case if I load up a profile in escribe that means I am ready to load it, not have to load it again after I plug the box in.

    If there is some major reason for this that I am missing , call me stupid, it's ok.
