So You Want To Go Mechanical - A GuideTutorial

So you want to get a mech mod?
Awesome! Personally, I find nothing else quite as satisfying as a solidly built mech mod. But before you take the plunge, it's important to understand how to safely operate it. Very few things can draw negative public attention to our precious hobby like an exploding mech, and it can happen if you aren't careful. I'm not trying to scare you away, I just want you to be 100% aware of the risks and 100% informed on safe operation of mechanical mods.
Ohm's law states that the current through a conductor between two points is directly proportional to the potential difference across the two points. Introducing the constant of proportionality, the resistance, one arrives at the usual mathematical equation that describes this relationship: I = V/R where I is the current through the conductor in units of amperes, V is the potential difference measured across the conductor in units of volts, and R is the resistance of the conductor in units of ohms. More specifically, Ohm's law states that the R in this relation is constant, independent of the current.
Wow, that's a lot of words. Here's your bottom line. You need to own an operational ohm meter if you want to use a mech mod. The only way to know how many watts you're pushing is to measure the resistance of your atomizer, and calculate that along with the voltage your mod is putting out. Once you have those numbers, it's as simple as plugging in V and R in an Ohm's Law calculator like the one on Steam Engine.[1] Keep that link handy, you're going to need it again in chapter two. There are also free apps available on the Google Play Store and the Apple App Store. I use VaporCalc personally. Keep in mind that your voltage is going to drop over time as the batteries drain. Keep an eye on that, and don't ever drain them below 3.2 volts, or else it becomes a very real safety hazard. Personally, I like to recharge at about 3.5-3.7 volts, as I find that to be the sweet spot for maximizing battery life.
Make sure you're getting your batteries from a reputable source, because there are a lot of companies who aren't above rewrapping batteries and branding them as their own. Two places known to be trustworthy are Lightning Vapes[4] and Illumn.[5] I usually advise people to just stick with Samsung 25R and 25R5, Sony VTC4 and VTC5, and LG HE4 and HB6 batteries. There are other acceptable batteries out there, but you can't go wrong with these babies.
Speaking of rewraps, let's talk briefly about battery wraps. Battery wraps aren't just stylish, they're for your safety. Think of them as condoms. If your batteries are starting to get worn, rewrap them! Wrappers are cheap, and they're an important safety device. And since you're already looking at your batteries, don't forget to periodically inspect your contacts for signs of arcing. If you see black or dark grey spots or rings on the ends of your batteries, discontinue their use immediately! Batteries are too cheap to gamble on questionable cells. And please, don't carry loose batteries. Store them in a case, you can buy one for a dollar on Illumn. The last thing you want is a fire in your pocket, your jublies are too close!
Last but not least, recycle your batteries when you're done with them, don't just toss them in the trash. Most electronics or home improvement stores will accept used batteries. Fry's, Best Buy, Lowe's, and Home Depot are all examples.
Well, that's all for today's issue of New Vaper Weekly. If you can think of something important I left out, or if you catch any mistakes, let me know so I can get it squared away. Happy vaping!

- Chapter One: Ohm's Law

- Chapter Two: Battery Safety
