I want to build a mod, but I don't know where to start... Help!

Hello ECF.

I have personally been vaping for over two years and have only now recently been interested in the world of mods and the building of them. I started out making a sleeve that would fit my ego style batteries (pic below) but found it kind of restraining on what I could actually create, as the form had to fit what I had, instead of reverse-wise. I want to make something quite different than the ego that I am used to, something along the lines of steampunk, like my ego "sleeve".

What I want to know is should I go electrical or mechanical? I have limited knowledge of circuitry and am by no means and engineer, which means if it has to have electrical parts ie capacitors, resistors etc... I am pretty sure I will get it wrong. This is the reason I am thinking about going mechanical in my build. But I have several questions regarding that:

- Should the body, which I understand acts as the negative terminal for the batteries, be a certain thickness? Would too much metal cause too much of a drain on the battery as there's more to push it through? If so, should I route the current through wires instead and have an electrical switch?

- If I go the electrical switch route, is there anything I should be aware of having in place besides battery+ > atomizer > switch > battery- ? I would then isolate that circuit from grounding out against the body if that is what is needed.

- The type of batteries that I want to use are ICR18350 900mAh 3.7v, as I have a good handful of them left over from when I had my screwdriver mod and it just died (kind of weird as it was a mechanical mod supposedly). I also understand that it is a bad idea to stack those, so if I want to get a bigger battery I will probably go with an 18650, unless there's something I need to be made aware of as well with that.

- What type of venting is necessary on the body/battery compartment to ensure safety? I don't want the batteries to explode in my pocket or hand.

As I am writing this, of course I brain-fart some of my other questions, but I got the main ones here. Thank you for your time and help.:blush:

- Rand

Think flashlight. That's how the first mods started (including your screwdriver aka romisen flashlight mod), rip out the light and add an atty connector. Study a flashlight and reproduce the simple circuit in your sleeve. Battery positive terminal to switch to atty positive post, atty negative and battery negative ground to the mod body. Simple mech mod. No you don't need to worry about thickness. A few vent holes in the base. As far as your "electrical switch" question, I think you're getting ahead of yourself, build a simple mod and in the meantime study up on vv chips, boosters, regulators etc, learn what they do and how they're applied then decide what you want out of the mod.

Something more crucial to keep in mind, if you want the mod to be compatible with high voltage or low ohm applications, the switch and batteries need to handle a high amp draw. AW IMR and MNKE IMR batteries can handle pretty much anything we can throw at them. 5 amp switch.

If you're willing to solder/assemble some pre-packaged circuitry with instructions, Madvapes sells a very novice-friendly VV circuit. It is not the most energy efficient circuit and requires 2 Li-ion batteries in series.

If you're a little more daring and interested in VW, there are a couple VW circuits that you add your own switch to, but the circuit is easy to connect. You can add a micro-USB charger ,as well, from the vendor. Check the DNA 12 and/or DNA 20 at evolvapor.com.

If you want to build a mechanical mod with possibility of expansion to boosted capability, keep in mind the Kick by Evolv, as it can give regulated out put via. A boost circuit that uses a single 18650. It turns any high-drain mechanical into a VW powerhouse.

I think you'll go far as a modder with your exquisite eye for attention and creativity. Your eGo sleeve is the best I've seen!

Like many things, Li batteries are made in a land of cheap labor and no copyrite protection, they will fake anything and say anything to make a buck. The reason they're doing batteries is because they also supply all the knock-off flashlights, torches and lazers to the whole subculture of people who like shining lights on everything, same people who've obsessed over the perfect battery for years and shared all it's gathered research with the vaping world. They're trying to rip off the flashlight guys.
