Here I am, teach me how to build please!

We've all squeezed a coil once with the pliers while accidentally hitting the power button and burnt a leg off.

Same as hitting the power button while rewicking, sometimes you can count the wraps in the burn mark.

When I started building an ohm reader was something you really needed, because alot were using mech mods and it was just a good idea to make a coil and know its resistance before installing on a mod. Now regulated mods are very good and now we have apps like steam engine that tells you so many wraps of this gauge and at this diameter will equal this resistance. I still liked the ohm reader and glad i used it. Basically you wrap a coil that looks like it's a good lenght and check it with the meter and it will tell you the resistance. You can also look at an app to tell you and you will be close, or simply build a coil and attach to a regulated mod and it will tell you. I still like to know before hand , so I still use an ohm reader....I like to straighten my wire section and still heat that lenght of wire before wrapping, this gives the wire rigidity for wrapping. I even like to over wrap on a mandrel by a few and then pull off a few wraps, this makes for some straight and taut wraps. Once installed, keep mandrel in, then pulse coil to heat. As the coil is hot, but not as your depressing button, you can work the coil to where you like it...once it looks good and you have set the height, then snip ends, but catch those ends because if they go flying, you might step on them.....its the wicking that is tricky

As the bottom of my foot has discovered, they can be a little painful as well. Not to mention loose trimmings can cause a short and possibly damage your atomizer.

Because that’s all anything could possibly be about. You forget how old the “knights” involved and how past high school they are.

Even if you use steam engine or some other app coil calculator, it is still conventional wisdom to measure the coil resistance on a regulated mod or ohm reader. There is always a possiblity that you made a human error making the coil. Unless you measure the coil resistance on an ohm meter or regulated mod, you'd never know.

Yep, and Steam Engine can't tell you that your coil is shorted to the RDA cap either. Again, on a mech mod bad, though merely a no-go on a regulated mod.

When I build for a mech mod I always build on an ohm meter and test the resistance with and without the cap installed before I fire it on the mod.

I agree and personally never used an app and believe physically doing things is the best way. Perhaps those apps are good just to tell you about how many wraps you need, but from there using an ohm meter. I also like and use a multi meter, besides telling me the resistance of a coil, it's nice to be able to check resistances without having to attach to an ohm checker tab or mod. Sometimes I make various coils ahead of time and it's nice to be able to quickly check resistance without attaching. So it's nice to have both sometimes, a multimeter and one of those 510 tab ohm readers.

Ohm reader tabs and regulated mod readouts are great for telling you if you've hit a target resistance, but the apps tell you what that target is. My next step is to figure out heat fux and capacity so I can predetermine if I like the vae a coil will give.pl

I use an app (vape tool pro) mostly to tell me how many wraps I need to achive a certain ohm range. It is also good for experimenting with new builds and getting the specs like heat it will produce at different wattages so you know before hand if it would be something you may be interested in without having to spend as much time and resources on physical trial and error.

It cannot tell you everything about a new build. But, for example, someone looking for a hot vape can tell if a coil would be too cool for their liking for a mech, or if it would need too much wattage to run on a single battery regulated mod.

Yes alot really go for heat flux numbers and I suppose it can be a useful thing to dial it all in, so it's a great tool perhaps.

I likes em hot and greasy in the 250 to 300 heat flux range.

Heat Flux is a measurement of radiant heat per surface area. With a regulated device this value is variable – adjust the power, the Heat Flux also changes. With a fixed voltage device this value to static, but requires adjustment to the Heat Flux until your correct voltage is displayed. The result will be your Heat Flux.

Example: 24 awg Kanthal at 0.5 ohms. To reach a Heat Flux of 200 mW/mm² you only require 23 watts on a regulated device. But that same coil at 3.7 volts (for a mech) would give you a Heat Flux of 240 mW/mm², or the equivalent of 27 watts.

Heat Capacity is a measurement of time it takes to heat a coil. With Steam this is calculated as the Specific Heat Capacity of the metal (which is not displayed) * Mass of the coil. Heat Flux can be identical with 2 different coils of different gauge, but the coil with the more mass will have a higher Heat Capacity, thus require a longer time to reach a desired temperature for the same given wattage.

Just a point of clarification: When you grab a coil with metal tweezers the current will flow through the tweezers and bypass the resistance of the coil. Current always takes the path of least resistance. In this case, the tweezer resistance, which is near zero (dead short), so the current is near infinite. It would be like shorting a battery with the tweezers.

On a mech mod - bad news. On a regulated mod - it should give you a "resistance too low" message.

I can confirm that’s exactly what happened on my regulated mod.
