Giraut - not sure if you are aware of this forum here: Modding Forum
You may find some useful information there to help with this project.
Yeah I'm aware of the modding forum. I've spent quite some time reading the threads there. But it won't help me much in this case: my project isn't about designing the perfect mod (although I hope it'll be pretty nice), nor being compatible with existing vaping hardware, but rather is a "clean room" design that purposedly ignores what can be obtained today in vaping stores or on the internet, and ignores the legacy standards all mod makers seem to insist on following today.
I'm imagining a world in which vaping has been banned, and trying to come up with a nice mod design that can be made in such a world, with off-the-shelf components that have nothing to do with vaping. The design will be totally open, and available to anybody who cares to make it. If someone else comes up with a similar project to create nicotine liquids, it'll ensure The Man can never ban it - and I wouldn't put it past our corrupt governments to try some day if they have a chance.
Not to mention, I think some of the technical choices in current mod designs are rather poor, and I want to explore other ways of doing things.
When my first prototype is complete though, I will most certainly open a thread in the modding forum.
