    hello everybody! WHAT HAPPENS IF I DONT MEASURE THE OHMS?

    The worst that can happen is that your battery explodes, blowing your hand off and launching your drip-tip through your face. OK, maybe that's not the worst. Someone on here had an EGO battery explode while charging and the burning bits hit her three year-old child. Or your battery explosion...

    "Sometimes it is too much"

    It's not just the mg/ml contant of the liquid that matters, it's also how much vapour the kit puts out. I've not tried Blu myself, but my impression is that it doesn't put out much vapour. If the Aspire is putting out twice as much vapour he isn't getting twice as much nicotine; he's getting...

    problems with kanthal wire please help me

    The only things I can think of are that you are not using enough tension or you have too high expectations. 30ga will spring back a bit but I find it easily manageable for a microcoil. It can't be twisted easily without a drill or similar. Torching wire is a tricky business. You want it to cool...

    Really Basic Newb Questions

    Just don't let your kit soak for three days. It turns out there's enough water in vodka to make stuff rust. :oops:

    Number of coil wraps

    I have 0.20mm (32ga) and 0.25mm (30ga). I've just wound a 2mm coil at 1.3 ohms with the thicker wire and I'm loving it. I've generally used the thinner stuff for a 1.8 ohm coil around two or three stands of silica. This one is maybe the first time I've bitten the bullet and put cotton in an RBA...

    New atomizer advice

    There's a comment on this You Tube review: https://www.youtube.com/watch?v=XbZOCWzF9_4 "To all the people that have any problems with leaking with this tank. Its a slightly different wicking setup than a Kayfun. It is a must to run a bit of the wick into the juice channels. Not to clog them but...

    ohms reader... multi meter

    I wouldn't trust a DMM below 1 ohm. I wouldn't trust an ohm reader from eBay unless I'd calibrated it myself with known resistances, but if I had, then it's going to be accurate enough. It's all about Full Scale and accuracy. A DMM might be accurate to 0.1% of full-scale, but full scale is...

    Can someone explain hardware basics? Ohms, watts, # coils, etc.

    Volts is the force pushing the electricity through the coil. Amps is the rate that the electricity flows at. There's some differences, but you can think of it like water pressure and flow rate in pipes. Watts is the power that is delivered to the coil by the electricity. If the pressure is...

    1st Time MOD Buyer.Need Advice.

    Personally, I don't trust clone mods. It you get a bad atty then it'll just not vape well. If you get a bad mod it could be dangerous. Not that I've heard of that happening. The SVD was the one I went for. The SVD 1 is a telescopic, which is good if you're not sure what size battery you'll end...

    Technical question for my box mod build???

    You'll need some more circuitry, but it need not be particularly onerous, just a small handful of components on a scrap of veroboard.

    Puffing ??

    If you listen to PBusardo's interview with the guy from Evolv, it is the hesitations in puffing that increase the coil temperature a large amount.

    figuring things out

    Congratulations on your success. The leaflet that comes with the Protank II gives suggestions on the voltage to use. For 1.8 ohms it says 3.3V. I found that about right but a lot depends on your taste, the liquid you are using and your vaping style.

    Flavors that may contain Diacetyl, are there really this many?

    It is not dangerous to the public, even in excessive quantities. It is only dangerous to the vaper. Say the member of the public is stuck in a car (4 cubic metres) with you for two hours and you are vaping a liquid that is ten times the safe level of DA. In that time you breath out 4 x 60 x 2...

    Flavors that may contain Diacetyl, are there really this many?

    The $200 price is quoted by a US test lab (the one used by Dr F.) for a DA and AP test at the required sensitivity. The ECITA tests are less sensitive but include other components such as di-ethylene glycol. They cost about the same, so for a comprehensive test maybe you double the cost. I would...

    Flavors that may contain Diacetyl, are there really this many?

    GVC was tested, as it says on the "certificate", in March 2013 under the standards set out by ECITA. That seems commendable and as much as a liquid manufacturer should be expected to do. However... At that time the tests did not check for AP although recently ECITA is checking for that too. The...

    Official DNA 40 introduction

    That doesn't sound right. If the batteries are wired in parallel, then the only problem you would have is that the batteries immediately short-circuit each other and vent. One might hope there was a diode in there to prevent it. But apart from fire damage, the DNA40 would not be stressed. I can...

    Official DNA 40 introduction

    There's a bit before that that says that the times that the temperature limit is hit are those times there is minimal airflow. When the user hesitates in mid-draw and at the beginning and end of the draw. So during normal use you are not getting to the temperature limit unless the airflow or...

    Flavors that may contain Diacetyl, are there really this many?

    Not quite. The limits Dr. F tested against are workplace limits. They regulate the environment that employers have to provide their employees. Vaping is not a workplace so the limits do not apply in law. They do appear to be reasonable limits and you may feel, as I do, that they should be...

    some newbie questions about moving from Ego to Mods

    There's a disadvantage to every mod that charges with USB. They tend to be limited to a charge current of 500mA, whereas separate batteries of the same size can be charged at 1000mA twice as quickly. You can generally vape while charging though.
