If you're giving up smoking, you've probably already tried (or at least heard of) electronic cigarettes - a reasonably effective way of getting hot nicotine into your system, without any of the tar or nasty cancer-causing carcinogens which come along for the ride with conventional cigarettes.

Unfortunately, the cheap ones available from petrol stations and mall kiosks don't last long and produce a negligible volume of vapour.

The more expensive models can produce decent vapour and have a more reasonable battery life, but they are not cheap, and even spare parts come at an inflated price.

This instructable will show you how to build a very powerful vapour machine with long battery life from a flashlight.

The build time should not be longer than a few hours, but significantly less if your fingers are nimbler and your soldering skills are superior to mine.

Step 1: Step 1 - Acquire your materials

For this instructable you will need:

A dead e-cig battery - I am using one from a Janty Ego, but others will work as they all have the same basic layout.
An aluminium bodied handheld torch - I am using one from Wilkinson (£2.99), but Poundland ones work just as well.
An 18650 rechargeable battery.
A soldering iron (and solder)
Plumbers mate putty.
About an inch of thin (and I mean thin)  insulated wire.
Needle-nosed pliers.
An atomiser or tank system. I recommend this one: http://www.totallywicked-eliquid.co.uk/products/replacement-coil-systems-2/dc-rcs-series/k1-dual-coil-replacement-coil-system-product.html

Nice! I tried finding a flashlight that would work but always had some issue with my batteries working in it. I have a battery operated soldering iron that I've seen converted to one and it would be cool to make it into a herbal vaporizer. <br> <br>I posted my DIY here http://www.instructables.com/id/DIY-Electronic-Cigarette/
This is interesting. I have a friend that used <a href="http://www.talkecigs.com" rel="nofollow">electronic cigarettes forum</a> that helped him quit completely. But for some reason it doesn't work for his wife. I'll have to show this to them. Thanks for sharing!

this is great! i switched to electronic about 3 months ago and ive been looking to upgrade to a better mod, but hey if i can do this it would save me about $90. kudos
Glad you like it. i'd love to know how you get on! <br>
So is it the atomiser that produces the nicotine?
Yep. The atomiser is essentially a mini kettle which heats ups the Propylene glycol to vapour
&quot;Torch&quot; ? I guess you are from the UK or downunder ! Greetings mate!
UK. Although I do plan on making a move at some point :)
USA ? Move to a place where the government won't tax you to death! Our town and school taxes are more than our mortgage payment! School taxes are out of control! The Teachers here get their raise every year, guaranteed. Even if they can not teach (or won't ) ! It is in their contract and their union forces it on us! So my monthly payment goes up every year. Si find a place with a tiny school population or next to none! You will be happy!
