Another use for DNA40 temp sensing

It's less BT, than Big Pharma though. Their sales of 'keep you addicted to Nicorinelle' is suffering, so they're on the offensive. 2015 will be the year of Us vs Pharma for sure.

Watch the VTTV with Marco and The Vaping Greek, Demitris blames BT.

Gonna watch that a sec again. I hope Dimitris is right! Rather be up against BT than BP, the latter have a much more powerful power base in the Antz in Parliament. Both have oodles of cash to stuff in back pockets though.

BP still in there, it is also talked about here

I'm really looking forward to the results of Dr Farsalinos' study on Temperature of Evaporation. Where the heat at which toxic chemicals are emitted from ejuice. It should debunk the myths about ecigs generating toxins except at high heat settings. I did a bit of background reading on the emissions from burning cotton, and they're CO2 and NO2. No sign of acetaldehydes. That would indicate the juice or coil, which puts the burden on atty and juice makers to tighten up their safety testing. Plus Dr F pointed out on VTTV that nickel, which a lot of folk are wary of, is stable if kept in the temp range the DNA40 permits. It's those prats (looking at you dejay) running mods with 10 batteries at god knows what voltage that are doing us a disservice.

Been playing around with the DNA40 and this seems to be a pretty good tool for testing coil/wick performance. 

1. Set the temp to max
2. Set the watts to what you would expect for your coil/wick/astty setup. Fine tune it a bit in use.
3. Press the fire button and observe the temp display. Note the average temp.
4. Try a different setup, maybe different wick material, different coil design (same resistance).
5. Press the fire button and compare with the first one. Lower temp should mean better wicking.

This is just an embryo of an idea, I  am sure there are many ways it could be improved on and experimented with.

It's called vanity vaping robby I vaped in front of the mirror for the first 3 weeks of issues with mine. did timed draws, altered the power and temp and tried every combination. I learn a lot in that time!

Without knowing about this thread I pretty much did this during my DNA40 (clone) learning phase. I didn't set the temperature to max but rather 470°F and played around with wicking and watts to get a consistent ~390°F for the duration of repeated draws. If the temperature continues to rise then the wicking wasn't good enough for the watts. It was interesting how much better the wicking was on a Magma versus a Lemo with the same 30ga ø3mm twisted nickel coil at about 0.12?.
