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.

So is it the atomiser that produces the nicotine?
davidstelephone (author)  Pat_Maroney2 years ago
Yep. The atomiser is essentially a mini kettle which heats ups the Propylene glycol to vapour

UK. Although I do plan on making a move at some point :)
