First Mod

[SurReality89]

So i can't seem to use this because my batteries don't seem to be working right. before i used them i check with a meter and it read and when i plugged it into the mod it turned on and died quickly, i thought it was the variable-display chip thing i bought because i also could seem to get it to change voltage with turning the nob on the blue part.

so it's not yet working, not sure if i will have to get new batteries and variable/display thing. but i am really happy with how it turned out looking because everything fits perfectly in the plastic box that used to hold thumb tacks. and/or i would probably just buy a separate parts to display the voltage and adjust the voltage and have a smaller mod.



also i was wondering what you would need to buy to have a display on your battery life, i remember cd players having something like that in the screen and they took AAs so i figure the must be someway to know when the batteries will die ahead of times (this was actually a request from a friend who would be interested in having a mod that did that)

your post isn't very clear, but I think you should spend more time diagnosing the cause of your issue before looking to work on new things. Is it the battery box, wiring, LM2596 board etc that is faulty.....?

 

[retird]

The picture is not very clear so kinda hard to see the wiring.....if you could post a diagram or a better picture of your wiring it may be helpful for us to aid in helping ya out.....

 

[BuzzKilla]

uh, im no pro here when it comes to this board, but is it supposed to take such a small battery?
those look like two AA battery trays.

are you using alkaline batteries to power this thing?

 

[retird]

he's probably using 14500 batteries.....or should be with those battery trays....if that is a buck regulator board...

 

[BuzzKilla]

you are right, but if alkaline batteries were put in, it could account for the lack of power....

The mis-informed will do the unexpected.

 

[retird]

hopefully he can post a bit more info and maybe a better pic so we can try to help him out a bit....

 

[SurReality89]

wut makes you think i'm misinformed? and yes they are 14500 batteries.

i will write up a quick diagram of the wiring:

battery1 (horizontal in picture) + > - battery2(vertical)/ + > "in +" circuit board/ "out +" > switch > center post of 510 connector/ outside ground > "out -" circuit board/ "in -" > - battery1

i hope you understand that, if you want i will draw it up and post the picture but its pretty simple. also after letting the battery charge all night it is not at all turning on, and i am getting a about 3.3 volts of them.... i going to do a quick beep through all the connection on the device, but considering the voltage adjusting is unresponsive i might write it off as bad luck with a defective circuit board.


wow i had the mixed up the - and + coming out of the circuit board. i got a little vapor off it but the voltage of the batteries dropped quick and went from about 6 to about 4.5 have vaping some. also the voltage is not adjust well at all, i got it to increase a little but it just would not be ideal. i think i'm going to buy a different VV board or something. and different batteries as they just don't hold a charge, it seems i just got very unlucky on my first mod.

I see 3 wires to the atty, what's up with that?

 

[BuzzKilla]

no offence intended, but i have seen some weird substitutions being done in the mod section, and was just making sure.

 

[Innocuous]

It looks like an LM2596 board.

 

[SurReality89]

retird: i wasn't offended, i was just wondering if there is something i have done that shows i'm misinformed. i am definitely a noob but i feel like i have an accurate lack of knowledge

I see 3 wires to the atty, what's up with that?

the switch is right next to the atty connector, also there is the negative wire for battery1 around there. i only have 2 wires connected to it.

thanks for the replies.

yes. this is the board Digital Display LM2596 Power Buck Step Down Converter Voltage Regulator 4 40V | eBay

Thx for the pics....will look at them later as I have to leave.....If I offended you I'm sorry, but I didn't say anything about being misinformed (thinking you just replied to the wrong poster).... no big deal....later my friend...will try to help ya out if I can.....be back

 

[SurReality89]

cool thanks, and no i was not offended

Glad ya got it figured out....sounds like a plan.....the board you used here was rated at 2 amps.....look for one with at least 3 amps out....

 

[SurReality89]

really? the listing says it can go up to 40 volts, i will look for a 3 amp one i suppose... this is a 3amp max i think DC DC LM2596 Step Down Adjustable Power Supply Module CC CV Output DC 1 3V 35V | eBay

it says i need an additional heat sink, how do i add a heat sink.

 

[retird]

Heat sink....thermal conductive material is added on top of the chip to transfer heat from the chip....google heat sink for more info...

and you can search this sub-forum for LM2596 and there is alot of reading and mod design here....

 

[dangkhoa02106]

As I saw, the board use LM2596S ADJ, this board need the input at 7V (but you should provide more than that) and this board can only supply 2A (continuous), even you attach heat sink it still not reach 3A (just about 2.7A). So if your diagram is correct, you should use a bigger battery (just like 18650) and of course you should use a better battery (just like Sanyo or Panasonic), do not use Trustfire or Ultrafire battery, many kind of this battery brand was made in China, it is fake and give poor performance.

As I saw I see the red wire (the wire that connect to the positive of the battery) attached to "IN -" , should it correct? By the way, you should turn off the volt meter if you do not use it, this kind of volt meter will drain your battery too.
