Mech mods & RBAs: Basic to advanced user guide: Pt. Two
I've exceeded the 10K character limit in part one... so, here's part deux!
> Addendum 2-17-14:
A coil calculator, developed by ECF member Dampmaskin and called "Steam Engine" (previously called "vape calc") has become available.
It includes not only an ohms law calculator, but a coil wrap estimator that includes parameters like ID, target resistance, leg or "tail" length, "heat flux" (coil temperature values), "heat capacity" (coil "lag time"), coil wrap counts... and a battery drain calculator as well.
IMO, this may prove to be the single most handy link any coil builder can have bookmarked... see 2015 addendum for updated information.
> Addendum 5-13-14:
Martin Lorton... a gent who knows a thing or two about meters, has produced a number of DMM reviews and buyers guides. Of particular interest to those looking for a good mid-price DMM... the 4 part series buyers guide UNI-T UT61E.
Coil building fixtures. Yes, you've seen the universal single coil fixtures you can buy... from under $10 for a Tobeco jig, to a good deal more for the Hexacoiler, Danish TotalSteam and QVapes Coiler. They all do the same thing... make it easy to build an assortment of coils in a variety of IDs.
Update 1-7-15: The "Kuro Koiler", designed by Jon Kuro ('Jkuro' on most forums) is out and available... and it works very well. Not cheap, but a very elegant and clever design, especially if you have a frequently used coil ID.
For the budget minded, there are now China clones of most of the above fixtures. In fact, FastTech has close to 50 versions/multiples available.
How about 'specialty' fixtures? Can't buy them... you have to make them. One of the very best RDAs to came out this year, is the Veritas - from "faceless" the maker of the iHybrid line.
Dual vertical coils and a unique air flow system that is near leak-proof... and allows for filling without any disassembly or DT removal. I got one... and the first thing I found out was that it's not easy to make a nice, single looped wire/dual coil set - on the atomizer.
Where am I going with all this? A guide to make your own dedicated "pattern duplicate" jig for an atomizer. Not just the Veritas... but any atty you think a custom jig might benefit from. Get creative!
> Addendum 10-27-14:
Tech Thing "Half-Ohm" plug-in adapter. What this is, is a converter that you plug into your DMM, allowing you to measure milliohm values quite accurately... for only $20.
Of course, the level and consistency of that accuracy will depend on the quality of your meter and test leads as well... but considering what a real, 4-wire milliohm meter costs, it's a hell of a deal and can be far more accurate than the usual cheap China ohm meter/build box.
Speaking of ohm meter/build boxes... if you like them and want a good one without spending $60-$80 - USA Ohm Meters makes one of the most accurate and consistent boxes I've ever used.
> Addendum 1-7-15: I've written a 2-part users guide for those having trouble understanding some aspects of the Steam Engine coil modelling program - part 1 and Part 2. the latter of which deals exclusively with heat flux and heat capacity.
Although Dampmaskin has done a wonderful job overall (for my needs, the best complete vapist's calculator made)... I felt a more in depth explanation was required for some users, particularly in the area of tuning wattage or build for a desired heat flux/heat capacity.
> Addendum 2-17-15: For those who're new to mech mods, and are perhaps having an issue with voltage drop (VD), and/or "hot button conditions... "How Mechancal Mods Work" may provide a bit of insight.
>Addendum 4-2-15: I've added several articles, which are extensions of Parts 1 & 2 of the Steam engine modeling program guide... they are:
"The practical applications of heat flux", "Sub-Ohm... what's the point" and "Optimizing heat flux - chart design"
Just like in part one.... Members that have, of their own accord, spent time producing valuable & practical educational material... for those seeking knowledge and understanding. If you get a chance, somewhere along the line, take a moment to say thank you to them.
As always, take it for what it is, do with it what you will.
