Hi Dampmaskin, love your app. Any plan for iOS version?
Looking at different vaping-related calculators online inspired me to throw one together of my own.
This calculator is for making coils (my latest craze), but I also plan on adding a DIY e-juice calculator later on (if the response is positive, and people are interested). The lofty long term goal is to have everything (vape related calculations) in one place. Anyway, enough talk, here it is:
Steam Engine | free vaping calculators
The calculator is javascript driven, and is supposed to work in real time without page refreshes. All is in one file (except jQuery and Bootstrap) to keep loading quick and light. If anyone finds an error, or want something added (or removed or changed), please give me a word, and I'll seriously consider it. I will appreciate any feedback, both positive and negative.
There is difference. Not overly significant but it is there.To be honest I'm not sure either. Is it a significant difference, or just a tiny one? It might have something to do with the normalizing "anchor" temperature, and conversion between C and F. My calculator regards 20C as "close enough" to 70F, but I'm not sure that is a good practice.....
Wow.........
Wire Wizard
Feel free to check it out, take everything with a grain of salt, and if you don't understand the first thing click "How it works". Then enjoy whatever works, try to enjoy whatever doesn't, and feel free to say exactly what you think in the Steam Engine thread.

Ok, i will check first what I can comprehend at all than make my suggestionsIf you want to help improve the materials data, that would be fantastic. Here it is, in all its questionable glory. It's stored in JSON format, with Javascipt style comments that I strip before use. (Everything between /* and */ is a comment, and everything between // and the end of a line is a comment.) As you can see the data is a bit patchy and sketchy to put it mildly, but it has worked OK so far.
The required fields are id, nm (name), rstv (resistivity), hc (heat capacity) and dens (density). In order to calculate TFR curves, we also need a TFR array (preferred) or a TCR constant.
The TFR array consists of N small arrays that consist of the temperature in °C and the resistance factor for that temperature. Preferably, 20°C should have a factor of 1.
Also, for the sake of the sanity of the DNA 200, every temperature point should have a higher factor than the previous one. That's why I've fudged the factors for Kanthal with some extra zeroes ending with a 1 at the lower end of the temperature scale.

copy that, I am on it1) As long as the DNA can handle it, I prefer 20°C. I'm a European after all. If the users don't like it, I can always do some output conversion to Fahrenheit later.
The temperature points for the output don't need to be the same as the temperature points in the input (materials) data anyway. As you probably have noticed, the different materials actually have different temperature points, because I used whatever I found, and made the calculator straighten it out. To find the TFR for an arbitrary temperature, I use linear interpolation on the material TFR curve. This means that the more temperature points the material TFR curve has, the smaller the "degradation" will be from using arbitrary temperature points in the output.
2) As far as I understand the DNA 200 has enough memory for up to 7 segments (8 points) per profile when using all 8 profiles. I don't know how much the refinement mode of the DNA is affected by the resolution of the temperature curve below vaping temperatures.
The only reason why I did not make the output temperature points user configurable, is because I didn't want the user to have to think about it. Changing them is very easy from a technical point of view.
If you have a suggestion for output temperature points, I'll throw them in there and we'll see how it works.
The question about what the DNA 200 does with temperatures outside the TFR curve, is an interesting one.
The Wire Wizard has had another overhaul or two, and can now be found in the menu.

The Wire Wizard now allows you to use a mixed coil, or a TC coil other than Ni200, on your Ni200 only mod.
Set up your build, click the "Ni200 equiv." tab next to the chart on the upper right, and enter a value from one of the "Ni200 equiv." rows into your TC mod.
