OK GUYS, YOU GOTTA HEAR THIS! I really wanted a #$^@ stick because of the fact the batteries will be easily/cheaply replaced and cheap atomizers can be used. I have been vapin' for a few months now and have gone through several units and I'm tired of expensive parts. I was always scared to mod....here is my experience. I went and bought all of the things for the nicostick (enough for 4, two 2x AAA and two 4x AAA so that I would have some until some specialty batteries/chargers arrive)...I quickly realized that an 801 atomizer would not fit in there (although it looked like it would before I opened it all up and tried)....I drove 30 more miles to radio shack and got AA battery holders. I used the same audio jack that everybody else has been using for the 801...I took some bubble hose (the stuff used for fish tanks) and put some heat shring wrap on that, shrunk it (as the hose wasn't big enough itself), stuck it in the center of that bad boy and then drove a flat tipped screw up through the bottom of it (use a flat head for this, you'll find it easier when soldering). I made sure the flat tip went up to where my atomizer would need the postive contact. I then used some of that epoxy clay type stuff (you have a blue layer and a white layer and you mix it like clay then put everything together and it sets in 5 minutes...) to hold my atomizer connection in. It looks very professional. I put everything else together like nico said...then I checked for shorts, none...then I put the batteries in, switched the box on.
You ready to hear the rest?
Are you sure?
You better sit down....
I am holding it, trying to get the guts to be the first to try (we have it open still at this point to make sure that nothing flashes or smokes or anything....) and I heard sizzling...I grabbed it from my husband and was like...WTF...I pushed my momentary switch, the sizzling stopped. At this point, perplexed, I put the box up to my ear and release the switch...sizzling...the stupid idiots at radio shack who dug through the parts drawers to find the switch gave me the "normally closed" circuit switches (I didn't think anything of the part number since they didn't have the part I wanted/needed). I didn't know there was such a thing as a "normally closed" switch! WTF...So, for the day, I have to hold the button down, let up when I want a drag...and switch the box off when I'm done. It's hilarious really. So, don't be a dummy like me, read your labels! I can't believe what a doofus I am. But I hope I made you all smile! ROCK ON THOUGH, this mod rocks! I thought my atomizer was crapping out on me and I wasn't enjoying vaping much lately (as we are waiting for our atomizers which just cleared customs today)...and now, I realize that it was just my batteries! The atomizer is great! I bet this thing is a friggin' freight train with a new atomizer! Thank you so much nico for the step by step. You helped a little old lady like me decide to get all technical and stuff! My husband was even impressed, it looks AWESOME!
