Wireless controled e-sig

[Gibrril]

Hi all,

I'm trying to build an e-cig that can be triggered with a remote control to start producing smoke. (for theatrical purposes)

So far, I'm thinking of using a push button e-cig and switch the push button out for a wirelles switch.

The setup (which needs to be as small and thin as possible) involves a 418Mhz RF transmitter, a 418Mhz receiver module, a 555 astable oscillator and an LM567 tone detector IC.
I've attached a scematic to make things more clear.
Which e-cigs allow for easy acces to the pushbutton contacts?
Also, most push button e-cigs do not produce smoke unless some drag is created.
Are there any that do produce smoke by just pushing the button? If not, is there any way of creating the drag?

Thanks a lot,
Gibrril

Interesting...
I'm thinking you don't really need a full ecig. Since you have the skill to build a transmitter/receiver, you could just build your own coil and set it in a pan.
It' basically just a coil of resistance wire wrapped around a wick that hangs into the liquid. You'd want to use VG as the liquid for more vapor.
Silica is the most common wicking material but cotton and other things can be used too
It would give you more options to increase the vapor and wouldn't limit you to an e-cig voltage or size
Most E-cigs use ~1.5 ohm to 3 ohm coils but some hobbyists go below 1 ohm @ 4Volts.
Building your own, it wouldn't have to be as enclosed as an e-cig and would eliminate the need for a second power supply.
My usual use on my e-cig is about 4 Volts, 2 ohms. Should give you a good starting point. If it's too hot (or insufficient wicking) it will burn and smell bad.
If you don't want to build your own coils, you could work with just a head or you could cut off a CE5 and remove the silicon piece
I would like to see this when it's done.
Did you by chance ask about this on /diy/?



Some info I got from somewhere here on ECF:

Hi, thanks for the reply!
No I didn't ask about it on DIY...
Correct me if I'm wrong, but if I only use the coil instead of the full e-cig, and a "well balanced" heating temerature, it will produce smoke even thought there is no drag?
My setup now uses 11mA.

About the heat, this "device" has to be hidden inside a piece of carpet. I was going to use an entire e-cig because they isolated quite good. How would I go about isolating the seperate coil so the carpet doesn't catch fire and produces real heavy smoke : ?

Thanks for the advice and list of components!

With the coil exposed it will make vapor that rises.
Not good for carpet. If they run out of liquid, they will get hot enough to glow red.
I think an enclosed one will have to have some kind of airflow. No idea how to accomplish that and stay small.

Thanks for the reply!
What exactly do you mean when you say "an exposed coil"?
The idea is to force the vapor into a rubber tube that takes it to a certain point in the carpet where it can rise and produce a puff of smoke. As it stands right now, the rubber tubing can lead to three different exit points, the one furthest away from the coil being about 23,5 inches from the coil. Can the vapor travel this far?

Thanks a lot,

How about something as simple as an air filter for a fish tank with the output tube connected to the LED end of an automatic 510 battery. I know for a fact that you can "shotgun" an automatic battery. Get a low resistance cartomizer and fill it with vg like the other person said and that way you just have to remote control the air filter

Hi,
Thanks for the reply.
That sounds like a splendid idea! Do you know by any chance how small and how silent these air filters can be? (do you mean air filter or air pump?)
The entire setup has to fit within a neoprene mat. So the components can be about 7 mm high and 15mm wide. The length does not matter that much. (the idea is that the mat can be rolled up and spread out without reveiling the construction inside)
Thanks a lot,

Hmm, theyre definitely not that small but the pump that I have for my fish is actually quite quiet. You're gonna have to find a different type of pump for it to be that compact and I can't really think of anything else that would work.

Not sure of the cost but the size looks about right

Thanks a lot,

I'll ask around on some aquarium forums if pumps like this exist... Looks quite exclusive and expensive, the gear in the link...
But it looks very promising indeed!

Thanks a lot!

Yeah the pumps on that website look like they're not cheap. Glad I could help a bit! I'd like to see what the finished product looks like
