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.
