My Bad ....*

[FRESH x913x]

a guy here inspired this. he made some with dual atomizers that gets power by USB. i decided to make a portable one, using 1 trust fire battery and a rechargeable NI-MH battery. those atomizers are getting a little over 5V. this thing has kicked my *** a few times, the hit is just awesome and feeds my nicotine cravings with 2 or 3 hits.

Nice!
I've tried it myself with 4 attys but inconvenience was too big.

Just as a sidenote, those two different batts are just trouble.
Have a look into two Lithium batts powering two attys, should be much safer
(you can tie the positive separate and the negative through the switch)

yeah i know its trouble but using 2 3.7V lithium batteries was a bit over kill to me so threw a 1.2V in there. havent had any problems yet for some reason, figured that NM-IH would pop on me but nothing bad as of right now. may just rewire it and see if the 1 trust fire would be good enough to power both atomizers, maybe youve tried this as well? if so input would be greatly appreciated!

Yeah, using those two different batteries is just asking for trouble.

You could wire two 3.7v batts in parallel instead of in series, that would give you ample battery life and keep the voltage at 3.7v - or you could simply wire one battery to one atomizer (keeping them on seperate circuits) and use a dual switch that turns them both on, or one at a time.

That is crazy man. Good Job
