Help!! Noob with 5v box mod with TI chip!!!

[Curvychic]

What TI chip is it? Does the mod have an adjustment thumb-wheel or small screw (pot) that you turn?

I'm not sure as this mod was given to me through PIF. There is no adjustment thumb-wheel or screw to turn. Just the button to fire and the switch to turn it on/off.

Does the regular atty get warm at all???? Put it on the 5 v mod and hold the button down for 10 seconds. Does it feel warm at all? Do you have a meter?

The regualar atty does absolutely nothing, no firing, no heat, no warmth, nothing. Hubby has a meter and the batts test out perfectly. The batts are both new and I'm using them in a handmade bottom feeder box that just came in today. Those same atties that wouldn't work on the 5v work great on the 3.7v bottom feeder. Batts work great too. No problems with the bottom feeder, just the 5v mod.

Did you say that you have some attys that do work on this mod?
And if so is it more than one atty that works.

 

[AttyPops]

Gummy..... She insists that it is connecting (the std atty and 5v) ....but the atty that works on the Ego doesn't even get warm on the 5v.... but the LR atty fires on the 5 v and the eGo. Kinda mutually exclusive. IDK what chip it is and if it has strange behavior, but you'd think that the atty would at least get warm..... fresh batts too. No settings so prob not a vv regulator.

Sounds like a connector issue so far... IDK what chip tho..... Know of any weird behavior on TI chips that cause them to not fire or think they are shorted or something? But why would the LR work then, but not the std atty?

 

[Gummy Bear]

it's beginning to sound like a hole/tear in the center pin's insulator.
Gotta get some more standard attys to test on it.

 

[Curvychic]

I've got some more on the way. It's EXACTLY as AttyPops stated. I just don't get it either. Doesn't make any sense AT ALL! It has to be connecting (the standard atty and 5v) because when I pull up the center pins on both, each of them just pushes back in when I screw the atty on the mod. I've tried to lightly screw it in....nothing. Screw in it all the way.....still nothing. But that LR atty has no problem firing! The standard atties that won't work on the 5V, work perfectly on a 3.7 bottom feeder box. The same batt works in the bottom feeder too. No one piece is faulty individually, but combined, the standard atty and 5V just don't work together. My hubby is baffled as well!

The new attys should tell the story.
What I was getting at is that the connectors from different companies have a different center pins. and weird as it sounds sometimes one brand will push the center pin of the batt connector differently than some other brand will and if there is a tear in the insulator it may not show up with one brand and will with the other.
here is a pic of what I mean

 

[Curvychic]

My atty pin looks like the one pictured on the left. This is certainly crazy. I'm a total noob at this mod stuff, but the more I investigate and understand, the crazier this is! LOL

 

[AttyPops]

While you are waiting for the new atties, if you don't mind another question, see if you can tell us what TI chip that is. There should be writing on it... you'll need a magnifying glass.

I think what gummy is getting to is that the center connector may be shorting out against the threads and the chip senses a short on the output side and shuts itself off.... Also, a short will bypass the coil.... so either way it looks like a dead atomizer. He's correct about testing with another standard atty. Now is that doesn't work.... it gets real fun from here.

The specs on the chip MIGHT tell us something about cut-off and short circuit protection. If it's too much of a pain, tho, don't bother until we test with another atty.

I still want to know what that chip is tho... just curious since you specifically mentioned TI but didn't say what the chip is. Another option is send us a nice big close up picture of the inside.

 

[Curvychic]

Okay, so the writing on the chip is as follows: PTN04056 CAD 081134V. This is written on a white sticker on a black box that is bigger than all the other pieces. Then there is a tiny black sticker on another part of the board that reads: R010. I was told this mod had a TI chip, but with no other info. There is definitely some extra stuff going on in there..... I will take a pic in the morning and post it. My camera isn't the greatest, but I will try to get as close as I can without blur. Thanks guys! I truly appreciate all the help!!!

If it comes down to it, I'd be willing to ship this to someone who is an experienced modder to look at it. (I'd want it back of course. LOL)

I'm assuming it has no adjustment and it's a PTN04050c regulator. No, you can not use LR attys at 5 volts.
Use a 2.5 ohm to 3.0 ohm atty. The 2.5 ohm will give you about 10 watts and maybe a little hot.

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

 

[AttyPops]

Lol @breaktru.... (besides .... no fair if you're the one that PIFed it. )

@CC... either the new atty will work, or it's an issue for someone other than me since I haven't messed with the PTN04050c...... That's a cool adjustable module that I'm surprised is a fixed 5 volts (if it's what I think it is it ranges from 3.3 -> 5 volts). Check again for an adjustment screw/pot.

Anyway.... The guys here that play with this module will help you more if the new atty/adjustment screw doesn't work. I'm out. Good luck!

 

[Curvychic]

No breakthru didn't PIF to me....unless they PIFed to the person who PIFed it to me..... LOL

It doesn't read PTN04050c, it reads PTN04050 (no c at the end of this one, and I originally thought the last number was a 6, but upon closer inspections it's a 0. There's glue or resin on it and it distorted it.) I swear to you there is no screw or wheel anywhere. I've looked everywhere inside and outside of the box and nada. Could it be that there should be one and that's what's wrong?

If the new atty won't work, and I do have the adjustable version (but set a fixed 5 volts), I wonder if they'd be willing to share with my hubby how to make it adjustable.....Hmmmmmmm.

A 4050 is adjustable, It may not be set up for that tho.
It is easy and we would be glad to help you to get it adjustable. But we would need a pic of it 1st.

 

[Curvychic]

Taking one now Gummy....
Will edit this post in a few to include the pic.

Edited:

Added 5 pics. I more to go. Sorry about the lighting. Flash is too much and no flash is not enough. It's overcast here right now, so no sun either. Grrr. LOL

Sorry CC... I didn't mean that I don't believe you. Gummy is correct, of course, it can be set to a fixed voltage. I'm just surprised that someone wouldn't make it adjustable if they were going through the trouble to build it in the 1st place.

 

[Curvychic]

Here's the last one. I have to go to my Chiropractor here in a few, but I will be back in a couple of hours. If you need any more pics, just let me know and I'll get them to you. Thanks for all your help!!!

 

[Curvychic]

Oh, I didn't take any offense!!! LOL Sorry if it sounded that way. I'm not much of a morning person. LOL You guys are awesome for helping me in the first place!!! I agree that it's kind of dumb to set it a fixed volt if it's adjustable. You guys rock and I love ya'll for helping me out!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

[AttyPops]

A single 14500 battery..... gummy.... that can buck/boost true? So does she need IMR batts? But then, why would the LR still work (since it would want more amps)?

 

[Gummy Bear]

I have mine set to a fixed voltage. It's just not the 5 volt base voltage that the chip will do. I have mine set to 4.4 volts. That's what I like and well,, I just don't need it to be adjustable. Perhaps the guy that built it liked 5 volts.
We will walk you through setting it up to be adjustable if you want to.

 

[AttyPops]

I understand that. I'm not saying you HAVE to make it adjustable.... I'm just surprised that you don't. It's cool. nm. Interesting mod with 1 14500 ... compact 5 v. I'm sure others have done this too.... I just don't follow the boost stuff much. I'll be interested to see how it shakes out.
