Madvapes 5v box mod question

[Dalton63841]

so after charging my batteries it seems to keep vaping as i drag on my dual coil carto, but after a few seconds (with any atty/carto) the led is red when i fire it right up then after a few seconds it turns green? is this normal?

I could be wrong but that sounds like a simple slow color change LED to me, which would be completely normal.

interesting.. just noticed it goes blue when i take an even longer drag haha. wish it would change when my batterys were low. im sure thats out there. just to make my mod that much more complicated

That is all normal, mine acts the same way. You really should stay around 3.0ohms with it, if you use LR atties/carts it is pumping a LOT of juice through them and is not good for the atty or PV.

When I added the cap, it stabilized it a little, and I don't get the green light so quickly on LR atties. But, like I said, I don't think it is a good idea to use LR atties anyway.

What regulator is he shipping with this kit these days? How many amps?

If you want to push it....your risk.... you get some high-drain batteries and a 5/6 amp regulator and install a heat sink like bstedh said (ratshack usually has heat sinks, or rip one off some old junk).

Well I recently started vaping dual coil cartos which should be fine because each coil is 3.2, other than that i vape a regular atty with carts. How does the cap stabilize it? What does it do exactly?

I tried building one of these last night. I followed these instructionshttp://www.madvapes.com/How-to-Build-a-5-Volt-510-Box-Mod_b_8.html. My problem is that when I turn the switch on it heats the atty. The horn button doesn't break the circuit. Also in those instructions it labels the blue resistor as 470k but I got 470m on it and 470k on the tan LED resistor. Any ideas/suggestions?

Pictures always help.
470M is way too big. you should have 470K for the regulator and 470 for the LED. Do you have a MM to verify their values? Also post the labeling on the regulator so we can look up the data sheet to see what it needs.

Double check for shorts as that is the most common problem and check to make sure you didn't melt the insides of the switch when soldering so that it is always on...

hey all, I decided to give a DIY mod a try. I am built the madvapes 5v box mod and have a few questions.

I got it all together and here is what happens. I am using a dual coil carto, two ultrafire batteries, when i hit the button, it works and the LED is Red. After about 3 seconds, the LED turns Green, then about a second later, the mod shuts off?

I am assuming it is a battery cutoff, but it seems odd it only makes it a couple seconds with fully charged batteries? Also, I do not have a cap installed that is shown in the instructions here, MadVapes e-Cig 'How To' Tutorials • View topic - My 3xAA 5v Box Mod since it didn't come with the kit. How big of a difference does this make? Thanks for any help,

I had the exact same thing happen, 2-3 second cutoff (DC's). I swapped out the batteries to a fresh/new pair and it works fine.

MV promised a few months back for an accurate howto but still hasn't posted one. Not cool if you're selling a kit IMO.

I bought it as a kit from madvapes. The link I posted has the pics and mine is wired as it details. The blue resistor(regulator) that they state as 470k is 470M. I verified with my mm. I checked the horn switch and it's fine. The 470 they provide for the led is actually 470k. So, if you follow their instructions, you end up with a 470m on your regulator and a 470k on your led. I can't find any shorts. I'll just head to the store and scrap my board.

Just got a 5v kit also and mine has a 470m resistor also. I didnt bother trying it when I saw it didnt match the directions.

I will check radio shack for a 470k resistor.

Regulator is a 378R05

Edit .... I messed up reading my meter .470m damn decimal points lol

Now vaping at 5v

Use the 470k for the regulator and forgo the led untill MV fixes your order
