There is a lot of information out there on creating mods for e-cigarettes and I have done quite a bit myself. This post is where I will supply useful information, tips, tricks and even dispell some myths about modding e-cigs. It will be an ongoing post that I will add to periodically as I think of things that may help you in your quest to build the perect e-cig mod.
- Tip 1: Atomizers do not have a polarity. I see searches all the time for Atomizer polarity. There is none. It is good practice however to use the center conductor of the atomizer as the positive and the case as the negative connection. It reality though, it doesn’t matter.
- Tip2: Atomizer Resistance: You really don’t have to know what this is but if you want to know… Atomizers have resistance. It’s measured in Ohms. The higher the Ohms, the more voltage you will need to produce the same amount of vapor. The lower the ohms, the less amount of voltage you need. Why is this important? Don’t buy a high resistance atomizer (HR) if you are only running the normal 3.7 volts a regualr e-cig uses. You won’t get enough vapor for your likely. An HR atomizer is made for mods that run at a higher voltage than 3.7 volts.
2. Wiring e-cig mods
- Wire Size. I see people all the time saying you need to use heavy gauge wire and such to wire your mods. Did you ever see what connects the atomizer connector to the actual battery in an e-cig battery? The wires a very tiny. I have never seen these tiny wires fail due to current so the wire size is not that imortant as long as you use standard hookup wire. The wires from a battery box are more than plenty big enough for a couple of amps of current that is produced by an e-cig.
- Simplest e-cig mod wiring: The simplest e-cig wiring goes like this.
1. Solder a wire from the plus side of the battery to one side of a push button switch.
2. Solder a wire from the other side of the pushbutton switch to the center conductor of the atomizer connector.
3. Solder a wire from the case side of the atomizer connector to the negative side of the battery.That’s a completely wired e-cig. You just don’t have an on/off switch or LED but it will work for all e-cig mods.
- LED Polarity: Although atomizers do not have a polarity, the one thing you need to worry about when building an e-cig mod and polarity is your LED. If you want an LED light in your mod, LEDs have a polarity and need to be connected in the correct orientation. Usually the flat spot on the side of an LED is the negative side. Also, the longest lead is the positive lead. Make sure you get this right or your LED will let it’s smoke out and not work anymore :).
Pushbutton switches, atomizers and on/off switches have no polarity so you are safe there.
Protected and Unprotected Batteries (myths and legends)…
- Lithium-ion: If you are using Lithium-ion batteries in your mod, make sure you are using protected batteries. Commercial e-cigs use lithium-ion for their size and charge denisty. If you are going to use them, make sure they are “Protected”. Protected means they will have a small circuit built into them to keep them from discharging too far or overcharging which will cause them to explode. Do not use unprotected lithium-ion batteries in your e-cig mods unless you are a very lucky person.
- NiMH: NiMH batteries are the rechargable batteries you can buy in any store (and what I use in my Puck e-cig mod). They are unprotected as many try to down them but… NiMH batteries do not need to be protected. They will not explode due to high drain or over charge like a lithium-ion would. NiMH are currently the workhorse of the rechargable battery market and are completely safe without any protection what-so-ever.
- NiCad: Same as NiMH but not as good for e-cig mod use since their charge dies off linearly.
- Tip 1: Make sure you keep your tip completely clean before, during and after soldering connections. Moisten a folded paper towel or sponge and clean your tips after every connection you solder so solder doesn’t sit on the tip for too long. This will save your tip from getting ate away from the solder rosin.
I will add to this post whenever I think there is something that will help you or when I see a bunch of searches concerning a certain topic where I feel I can add some value to you.
