content: Quote from: Mechanical Menace on October 28, 2015, 05:11:54 pmLooks like a mechanical type one. Unprotected IMR type li-ion battery, mechanical switch, resistance wire, no protection. The worst part is that some "hybrid top cap" types dont even have an internal contact on the battery. The contact of the atomizer unit pokes though the top cap, touches the top of the cell directly. However some atomizers dont have a center contact (positive) which protrudes from the negative threaded sleeve very much (< 1mm) they are intended for units with a spring loaded center contact, where this is fine. But in a hybrid top cap setup, this poses the risk of the threaded sleeve, and center button both touching the top of the cell, shorting it out. A little contact welding as a few hundred amps flow, and it can get stuck like this. I dont know if thats a hybrid top-cap unit or not, but its been a significant risk in the past.High end or dollar store doesnt matter at that point.http://www.smokelesssmoking.com/collections/mechanical-mods/products/rsm-hybrid-by-rocket-science-modshas the same risk ashttp://www.fluidvapes.com/2six-26650-mechanical-mod-clone&currency=USD&language=en?gclid=CJLU-pbb5sgCFc-RHwod7WABbg($300+ vs $12 if the links arent working right)

content: I wonder what type of e-cig that was, because 18650 fires seem to have become extremely rare over the last few years - you can find plenty of videos of lipos catching fire on YouTube, but almost no 18650s. The few explosion videos I can find are fromextremeovercharge and abuse.

content: Quote from: janengelbrecht on October 28, 2015, 05:12:08 pmYeah I agree. In my opinion this borderlines the "stupidity" category. If you're stupid enough to smoke (anything), you get no sympathy from me. Those e-cigarette things are not only ridiculous but are by no means good for you. Harsh... perhaps but it's just my opinion.

content: An "e-cigarette" or vaporiser is nothing more than a heating coil wrapped around an e-liquid (mostly glycerol & propylene glycol) soaked wick. The danger is that the heating coil needs a lot of current, especially if the vaper is into "cloud chasing" (wants a lot of vapour believing that a human fog machine is cool). This kind of e-cig-blew-my-face-off mishap happens a couple times a year, and it's almost always with an improvised home-made device by some silly person wanting more clouds.And they are almost always young men. It's very much like hotting up cars and driving them too fast. They do the same to their e-"cigs": hot them up and drive them hard.The main culprit (after stupidity) is the battery, followed by battery housing and connection of battery to the coil being compromised. If you get a cheap or counterfeit battery, put it in a sealed tube and draw too much current from it (let alone short it), you have a pipe bomb in your hand that you're pointing at your face with the mechanically weakest bit of the apparatus between your teeth.Off-the-shelf devices with good high-drain batteries never do this. Just look at this thing! This is not an e-"cigarette"; this is a cloud-chasing fool's 18650-pipe-bomb vaporiser, who probably put a ~0.05 ohm coil in it.The odd thing about these cloud-chasers that it's not about the drug, i.e., getting more nicotine into your system (a $10 low power device can deliver as much as the human body can take without discomfort). It's about the supposed cool factor of a being a human fog machine.To our recent member with limited electronics knowledge and home-made E-cig project,bumba000:don't become this guy!

content: Quote from: edy on October 29, 2015, 01:11:09 pmRegulation will never stop this kind of idiocy. It's as easy as pouring petrol and lighting a match. Blind regulation of genuine e-cig devices will only hurt smokers wanting to quit. You can't regulate against someone connecting a bit of nichrome wire to a battery and dipping it in fog juice.And that's basically what these extreme vapers are doing. They cut right back on their nicotine (quite often to zero nicotine) just so they can blow big clouds. They are not representative of the vast majority of vapers who just want a healthier alternative to smoking. A regulation or certification scheme as far as electrical safety of devices marketed as e-cigarettes would be good though.
