I'm just curious, do these websites have magical powers? Can they tell you when you have a short? Does Panasonic or Sony use a website to "calculate" the voltage regulation on your TV? Would they ever try, heck no, they don't want to sell you that one TV that wasn't made correctly and have it blow up in your house.




In my opinion they promote laziness and make it easier to do something really stupid.
You should have both. A good ohm reader and a calculator...jeez.

I use the a fore mentioned site to get an idea of what I need to do to make a coil to the specs I want, then I test them with a multimeter. I also feel that they are way safer to use then just going on the net and asking how many wraps you need.
Totally correct.....

I'm against using any form of website to calculate "wraps" which completely differ with different size gauge wire and coil diameter. I'm going to sound like a snob but so be it... if you're building coils sub-ohm or not you should have at the very least a small ohm reader which is 20 bucks practically anywhere these days. Don't go to a website, test it yourself that way you KNOW for sure what you have.

I would assume that everyone checks their ohms. It does, however, save a lot of trial and error knowing approximately the number of wraps given a gauge of wire and size of mandrel. Can't see anything lazy in that!

As I stated before I do have a ohm reader

It isn't as if kanthal is that expensive guys, and a notebook to keep notes on your coils is nearly free as well, or keep notes in Google documents for the ultimate in penny pinching.

This way you have a very good idea of what you'll get with your own wrapping skills and equipment.

I'm almost certain very few check the kanthal for real diameter with micrometers, and I would think nobody actually checks metallurgy of their wire.

What we can check is ohms per yard/meter and extrapolate ohms per smaller unit of measure and punch a few numbers to figure out what length of wire will be needed to get a certain resistance.

The proof is of course in the final build.

Maurice.

Well....frankly...I use the app....its been accurate for me. I dont know about the steam engine sheet. I also have a good experience base...but, that being said...its good to do do experimenting on paper first. Being an engineer..I have been doing it for years sucessfully and have had great sucess in applying that to coil building. Since its been pretty bang on for hundreds of coils..I'd rather use the Vendors Toolbox app.
