Possible Solution to 901 fitting to avoid battery destruction

[nicowolf]

ack! be careful with that. you need to ohm out the center contact on the connector and see which lead it goes to on the bottom of the connector, then see which lead is ground. Make sure the center pin isn't shorted to the ground pin. The center pin needs to be connected to 3.7-5v positive and the outer casing needs to go to negative lead on the battery. hook it up like that then measure the voltage from the center pin to the outside casing. If you have 3.7-5v the connector is working. That doesn't ensure the atomizer will fit properly onto the + and - pins though. Once you screw in the aromizer quickly test for 3-5 seconds then unscrew it otherwise you may burn the atomizer up. If your battery got really hot something is likely shorted and that battery could be a goner.

Yeah, I am soooooo outta my league here. I have nothing in my toolbox to test electric - except maybe enough stupidity play with electric to begin with (yep, that was painful, musta been a connection there somewhere)

Well, if any of you guys who know this stuff get the urge, at least there is something out there that will fit physically - electrically, I dunno.

I gotta get some sleep now, maybe I'll be inclined to endure some more pain tomorrow.

well, let us know if you ever figure it out and find a way to explain it to the unsavy sparkies.

Ok, Bastage. I will calmly sit and say a few ohms to my screw in connector thingy. I know this will leave me grounded and centered, but what will it do for my connector thingy?

Not sure I follow what you are saying. Can you draw it up?

I am saying the only ohming I know about has more to do with meditation than electric. Reader's digest version: WTF?

Everything I know about wiring can be summed up very quickly. Red wire goes to red, black wire goes to black, any other wires means I'm in over my head.

Maybe this will help you understand my sarcastic, word playing sense of humor.

lol you got me. i was like this doesn't make any damn sense at all.

[nicowolf]

that's just what wnet through my mind when you said I should ohm this dofunky. I have heard of ohm as some kind of measure of some kind of resistance, but never as a verb. How do I do that? Does it require more than a soldering iron and some power?

Picked one up today to play around with. It does fit the 901 atm perfectly, thread-wise. Couple of observations, so far:

• The threaded portion is none too long, so if you were going to use the supplied washer/nut to secure it through a cover-plate (as in the "Magnum"), you wouldn't have a lot of threading sticking out to attach the atm to.
• In addition, the center pole is recessed within the outer body. It will contact the center of the atm if you remove the nut and washer, but doesn't appear to if the washer/nut is in place....that could be a more significant problem if you wanted to use the nut/washer to mount it.
• The rounded "nose" of the center pole effectively blocks the center hole of the atm if everything is snugged up. I think the hole in the atm is to allow airflow through the battery in a regular e-cig to activate the air-pressure sensitive switching that's contained in the battery (there's a corresponding hole in a regular battery), so that may be a non-issue for a flashlight-based mod. You could probably get around this by bending the center pole slightly to the side if you wanted to. I didn't notice any significant reduction in air-flow with the atm threaded in place on the connector, btw.

This could be a very nice component to use, with a little 'tweaking'. Rather that use the supplied washer/nut, I'm thinking that an oversize hole through the cover plate which would allow the atm to fully seat on the center pole would be a good approach. Since the connector has a larger diameter base plate (to allow panel mounting), a healthy fillet of 'J-B Weld' on the back side of the connector/cover plate might do to keep everything together. If the threaded section was a bit longer and the center pole was flush with the top, this would be perfect....oh well!

Oh, almost forgot. The lead diagram is on the back of the little card-pack it was packaged in. If you take the nut off, you can see which lead is connected to the casing. The other two leads are to the center pole. One is insulated from the case, the other is not. Use the insulated one for your center connection - it's the one attached to the plate all the way on the back end of the connector.

Thanks for pointing this one out, Nico!
