Instructive, and better for your health too... :-+

Unfortunately to do that you have to destroy it as its all sealed/glued together.

Yes, that's why taking it apart is good for your health. ;)

Ill take a small amount of glycerin over 400 known carcinogens including radioactive lead and polonium. I only smoked for about two years total but I smoked a lot if I could I would chain smoke but I knew better. Nicotine is way harder to quit then heroin. Heroin you feel better after a few days but nicotine is a mental addiction that's not easy. If cigarettes were illegal you would see people steal and kill for them. .
Audioguru:
The heater in an ecig has a positive temperature characteristic like most heaters. Then it draws more current when it is cooled by taking a puff.
To charge the lithium battery they use a Lithium battery charger IC, not a micro controller.
MANY people have quit smoking and there are a few good methods to do it easier. I laugh when I see somebody disappear in a huge cloud of Vape.

Car ECM is a good example. I don't imagine a future where it goes down to the level of clocks or coffeemakers, though. :) That would require the death of capitalism. (High degree of standardization and non-disposability of things, before it would start to be practical).
--- Quote --- Is this the circuitry inside realizing that if you try to use it while plugged in it will pull too many mA and it switches the heating element to the battery?

The reason the draw goes up to 685 is you took a puff. This means the battery needs to charge, again, at constant current of about 666 plus the extra 19mA the micro draws while it is awake. After that minute, the micro shuts down unneeded peripherals and/or switches to a much lower clock frequency just polling the button (or triggering on edge interrupt of the button pin).

I have a clock that is made out of analog needle multimeter gauges. Coolest thing ever and had to buy it. It has a micro in it and USB port where you can program it to do anything you want according to the instructions. Setting it also cool by turning a rotary encoder as the needles bounce back and fourth. Mine does hours min and seconds and I painted the needles different colors.
I plugged in an identical ecig and that draws 585. If its in constant current mode it doesn't change much when you puff it. It goes .666 for an hour then to .785 for a few minutes then goes down to almost zero. Does the chip inside read the individual battery rather then it being set to .666 at the factory?
Is this why I tried to put a slightly bigger lion batt in a Bluetooth speaker and it won't charge? Went from 600 mah to 800 and will power on but not charge.
