    Lightbulb Atomizers: Why they suck, and how we can fix them.

    When it comes to e-cigs, the biggest problem I've encountered (and I think this is the same with most others) is atomizer lifespan/efficiency.

    An e-cig is basically a resistor that uses electricity in order to heat and vaporize Glycerin.

    The problem with this is that current atomizers use cheap resistors (heating elements) that oxidize quickly. Basically, the atomizers bind with oxygen molecules and degrade slowly over time.

    There is a simple answer to this (in my opinion), and that is the use of a more expensive heating element that will not oxidize quickly (or nearly at all). The material is called Nichrome, and is a nickel/chromium alloy that does not break down over time.

    I, myself, am currently in the process of designing my own e-cig (not a mod) that uses a self-feeding nichrome atomizer. I'm still trying to figure out what technology I'm going to use in order to make it self-feeding, but I have a few options that i'm looking at.

    If atomizers were made with nichrome, our problems may be answered.. is all I'm saying.

    Just my 0.02

    check the mod forums it has been discussed at length

    Okay, damnit. just thought that it should be posted here (i it hasn't) because this is something that manufacturers should be doing, not just private modders.

    While we would all love the immortal atomizer, it probably makes little economic sense to a manufacturer who wants to sell us replacement parts to keep up the income stream.

    Atomizers are made with nichrome coils... it's wound around either a silica based fiber wick, or in some cases, a ceramic rod. If you've found an atomizer that's not constructed with coiled nichrome wire heating coil, post some pics.... that would be interesting.

    Then what is it we see when the wire is charred and nearly reduced to ash?

    I'm just saying that since Nichrome is one of the more expensive materials used to create heating elements, do you really think that the Chinese would incorporate it into their designs when there are many more available, and cheaper materials?

    That charred mess is residue of the liquid. There really is a a coiled nichrome wire under there.
    Check out M401 atomizer disassembled - pics

    There really is nothing else that would work properly. I've measured it with a multimeter and a digital caliper, and it matches 38 gauge nichrome wire.

    The reason they die is usually from snapping. Snapping is either from the 2500 heat cycles you just put it through, or in some cases from stress from a build up of the charred stuff you saw, pushing up on the coil while you puff on it. Ones that die a REALLY early death come from bad assembly, nicked wire, or some other physical problem.

    Some (reputable people) have had the coil wire pop out of the solder blob too, although I've never actually seen it happen.

    Most will last a couple weeks to a couple months, not that bad really when you consider you're pumping in the neighborhood of 1.3 to 1.8 amps thru that tiny little coil...

    Methinks it is deposits of juice vaped in the past coating the wire. Cleaning cycles, that have been feared by many, were probably designed to reduce the deposits. A good burn off now and again might be better than the thousands of cleaning methods developed each week.

    oops, forgot... nichrome wire is cheeeeeeeap in bulk. thousands and thousands of feet for $10. Around an inch goes in an atomizer

    Planned or Built-in Obsolecsence is a term often used in the manufacturing industry or in Chinese it is pronounced Fitchi ta wasaki nunch...Which means if you make it too good you wont sell any more...Its why BF Goodrich bought the recipe for the rubber tire that never wears out and why the Giant oil companies have lobbied to ignore Hydrogen Synthasis, and why Big Tobacco hates Ecigs...And why Aunt Jamima hates Bees.......................
