I want to make it variable voltage and be automatic instead of manual. I was thinking it through, most automatics are assembled in this order: tank, airflow sensor, battery. obviously with the airflow sensor built into the battery, since I'm making my own i want a different design that will go: airflow sensor, tank, battery. this will allow me to use any battery i want. but the main problem I have is I have no idea where to buy the sensor I need and I'm still a little iffy on how to make it variable voltage. Thanks in advance.
I need help making an automatic ecig from scratch

Don't get me wrong, I am probably an inventor at heart, and definitely a tinkerer, but why do you want to reinvent the wheel? I am just curious as always, not trying to discourage you. I understand you want a different design but I am not understanding how the design will make any difference at the end of the day. Are you meaning you want to be able to say be able to use a few AA's one day and maybe a C the next?
Well a big problem is the sensor will short out if the liquid leaks to it... I am hoping by putting the sensor above the tank it will fix that problem. And yes id like to be able to use any battery I want so the sensor not being part of the battery also helps that

That's an airflow sensor, but I'm not sure of the specs--the data sheet link goes to Honeywell's site directly and isn't obvious. This one's a 6 pin DIP, so pretty easy to work with.

There's the entire list of pressure sensors. I'm not exactly sure what we'd need to make an e-cig. Please notice they're not particularly cheap...

Oh, for VV...you'd probably use a lithium battery as a power source (nominal 3.7 volt) and use a buck/boost chip to raise or lower it. One that accepts a potentiometer (a variable resistor on a dial or slide) as input to choose the voltage would be best. I can't say I know much about buck/boost controllers; I tend to create boost controllers when I build them...and then I do it from scratch. My specs are also very different, usually boosting 1 to 1.5 volts up to 4 volts or so.
I wish I understood all this. LOL I AM NOT in any sense of the word an inventor of anything electronic. 
Just an idea, but why not create a tank screw adapter with a built in air flow adjuster that you can screw on the bottom of a tank and then screw your homemade vv battery onto that? That way your possibilities with tanks, adapters, threads, batteries could be endless.
I want something like this but it doesn't solve the issue i have with having it being on the other side. I'm trying to make my mod look like an asthma inhaler.. but on the inside be structured to a regular ecig.. kinda. so the sensor could be on the inhale part, but thats not exactly where the tank is and just have the vapor run through the device to the mouth piece
The only thing I could think of would be to use a VERY tiny sensor in the mouthpiece of the tank (if I'm reading you right). Wires would have to run to the controls in the base--at least three, depending on your sensor, for power, ground, and signal. Some of those may require more than four wires, which would get a bit hefty.
Most e-cigs seem to use an integrated IC or series of ICs, which we don't have the option of doing (if I could put some things on IC they'd fit on the tip of my pinky, as is they take a square inch of board). So I think you'll need a fairly hefty amount of space no matter what you do...
I don't care if this thing is the size of an apple really but here is a crude diagram of what i want to donot sure if this is just me but that post got messed up, orange is the airflow sensor, blue is a carto or atty and green is the battery. and the red lines is the airflow.
The problem with this is if you want to use the same technology already built into automatic e-cigs that design won't work. The sensors used are all well in good inside the battery when an air flow across the sensor activates it. But those sensors aren't designed to be put in the path of all the moisture being put across it in your design by being directly in the flow of the vapor it produces. You could create two separate pathways - one for air to only pass across the sensor and a separate path for the vape, but one exhale into the sensor could render it useless until it dries out again.
I don't quite understand your nebulizer analogy. To my knowledge nebulizers don't have automatic air flow sensors to turn them off and on. Emergency nebulizers are pressurized inhalants. Electric ones are for extended therapy - on/off switch.
I know of at least one modder who makes an asthma inhaler: Affordable Mods - My Mods
He doesn't have one pictured on his site right now, but all of his stuff is made to order anyway.
If you have your heart set on making a mod of your own, you may want to check out Puck Mods. He's been around forever.

The store by me has one that looks exactly like an asthma inhaler. If you want I can go over, take it apart, and take pics of it.
Sorry for going off topic, an idea struck me. Do you think it would be possible to rig an airflow sensor to vv circuits in a way that voltage would increase with a more powerful draw. I have no need for such a device, but the cigarette-like operation might make the product even more compelling for smokers

not sure if you helped the o.p. but you helped me. I have been looking for a vv auto thank you so much for that link!! Now I can hopefully finish my project! -cheers
