I did a project similar to this back in May. My Pure Smoke device broke so I had to replace the heating coil from it. I went out and bought a $7 disposable E-cig and took it apart.

Inside you will find a long thin battery, a burning tip LED, and a wet tube of cloth, almost like a candle wic, with wires coming out of it. When I did it, I cut open the wic and pulled the heater coil out, but for your project, you will want to leave it in there.

1. I'd say cut of the LED, and the battery. Go to Radio shack and by a AA battery enclouser with space for 4 AA batteries and either a push button switch or a single pole single throw switch (essentially a switch that is either on or off like a light switch). No idea where you would get the squeeze bulb, maybe use a turkey baster bulb?, but you can get plastic tubing at the hardware store. You will also need a soldering iron, some electrical wire, and heat shrink tubing.

2. You will need to solder the electrical wire to the original wires going into your wic. Cover the two wires with heat shrink tubing at the point where you soldered so they don't short circuit. Push the wick down into your plastic tubing.

Attach one of the wires to the switch and then to the positive terminal of your battery enclouser. The second wire goes directly into the ground terminal of your enclouser.

3. I'm envisioning two ways to go about the switch problem. One you can use a push button that activates as you squeeze the bulb with your arm by just taping it to one side of the bulb. The other way would be to put the SPST switch somewhere you can access it discreetly and turn it on just a second before you squeeze the bulb and turn it off right after. If you leave it on too long the smoke will continiously flow out as it escapes from your sleeve. Personally I'd say the push button is easier if you can get a push button that triggers easy enough.

All in all I don't see this costing more than $20 to $30, and less if you already have all the tools.

When I did it I stoped at step two because I used the exisiting swtiching and battery components of the Pure Smoke device.

I hope this helps. Feel free to ask if I didn't explian something well.
