Custom data

      14 Comments on Custom data

Now you can add your own custom wire materials, batteries or mods to Steam Engine.

How to find it

Click the question mark icon in the menu to reach the about page.

Then click the custom data button.

Entering data

Fill in the appropriate form and click Add. The new custom preset will appear in the list above the form.

Importing data

Paste your own favorite wire, battery or mod in the appropriate input box as JSON data. You can find some example data below each input box.

How it works

The custom presets are stored in the local storage of your browser. If you want to see it in another browser, you’ll have to import it there too.

Save the JSON data elsewhere if you want to take it with you.

Any custom materials you add will show up in the material select boxes in the Wire Wizard and the Coil Calculator.

Any custom batteries will show up in the Battery Drain calculator.

Any custom mods will show up in the Mod Range calculator.

Other  changes in this version

  • New material: Zirconium (pure).
  • New material: Resistherm (TCR).
  • A couple new mods.
  • Various tweaks and fixes.

    hello, I read your post to understand how to use custom data page and obtain a custom wire for tc profile having so a material csv file to import on our dna.
    I ask to wire seller (zivipf) info regarding value needed on steam engine page for zirconium the sell on they site.
    putting that I have a problem :
    resistivity = Ω mm²/m : ohm-cm ….. 397e-005
    heat capacity = J/g×K : 275
    density = g/cm³ : 6,51
    tcr = /°C :260-280
    tfr =

    for the resistivity I used an online converter : Ω•mm²/m = 39.7

    i found the new named material on wire wizard page but cliccling on dna to get csv no data are present and no download button on setam engine …
    have u maybe some tricks to suggest or explaine where I’m getting wrong?
    thank u in advance

      Hi. In order to get a TC profile, you need to supply either the TCR number, or a list of TFR values for at least two different temperature points. The TCR value is a single number that says how many ppm the resistance increases per degree Celsius. The TFR data consists of two or more different temperature points. Each temperature point has an associated resistance factor. For example 20 degrees has a factor of 1, while 100 degrees has a factor of 1.1, and 200 degrees has a factor of 1.3. This is written like [[20,1],[100,1.1],[200,1.3]]. It’s usually easier to find (and enter) the TCR. The TFR is normally only used when very detailed data is available, and when the temperature curve is rather non-linear.

    hi, thanks for kindly reply.
    The page issue was my issue because I found that I was using two different browser session 🙂
    So I made it right but still have problem: so without tfr (2 at least or more for better result) I cannot set in the right way the material?
    I get this result(csv content) using the data in my previous post :
    “Temperature (degF)”,”Electrical Resistivity”
    -58.0000,-18899.0000000000
    68.0000,1.0000000000
    212.0000,21601.0000000000
    302.0000,35101.0000000000
    392.0000,48601.0000000000
    482.0000,62101.0000000000
    572.0000,75601.0000000000
    800.0000,109801.0000000000
    trying to load it on dna I get an error.
    any suggestion will be very appreciated.

      Your numbers are way too large. Here are typical data (this is Ni200):

      “Temperature (degF)”,”Electrical Resistivity”
      -58.0000,0.5800000000
      68.0000,1.0000000000
      212.0000,1.4800000000
      302.0000,1.7800000000
      392.0000,2.0800000000
      482.0000,2.3800000000
      572.0000,2.6800000000
      800.0000,3.4400000000

      As you can see, these numbers range from 0.58 (at -58°F) to 3.44 (at 800°F). Your numbers range from -18899 (at -58°F) to 109801 (at 800°F). If you’re using a TCR, my guess is that your TCR number is off by a few factors of ten. In other words, move your decimal separator more to the left.

    wthe tcr value I used come from the seller (like all the other data).
    I filled the tcr value with 270 before, but changing as u suggest to 27 nothing is changed in the steam engine result.

    I will try to get technical data sheet of the wire (if they have) , in the meantime if u any other suggestion do not hesitate 🙂
    have a nice day

    changed as u suggest, below the new result :
    “Temperature (degF)”,”Electrical Resistivity”
    -58.0000,0.9999125000
    68.0000,1.0000000000
    212.0000,1.0001000000
    302.0000,1.0002500000

      That seems much more plausible, at least now the temperature factor is not negative.
      The JSON should look something like this:
      {"nm":"Zirconium (Zivipf)", "rstv":0.397, "hc":0.275, "dens":6.51, "tcr":0.0027}
      I hope it vapes well.

    onestly I haven’t try it 🙂
    I write an email to seller (zivipf) hoping in some more detailed data. Generally theay are really friendly and fast on customer care.
    I will update u as soon I’ll have some news by them.
    Many many thanks for interest and your truly kind help 🙂
    have a nice…evening (here 🙂 )

    Hi, the seller send me an image with wire specification.
    How can I send it or post on this 3d?
