The Dreaded LED

[JamBandPhan]

I managed to make a multicolor led mod. Since I can't post links just yet, go to youtube, search "510 LED MOD" and you should find the short video I posted showing the mod. This was my first attempt at any kind of e-cig mod (aside from replacing the cart filler with blue foam). I rigged up a single bulb, 3 color LED to the tip of the blue LED battery, by removing the cap on the tip, dissecting one of my key chain LED color changing lights, cut the leads on the multi color bulb to a nub,and glued it down making the contacts touch the connection for the original blue LED inside the battery tip. I made a cap from one of the plastic pipettes, the part you squeeze, it was a perfect fit over the end of the battery, and left room for the new bulb to stick out. It's not color fading as I would like to have, but it does have a flicker to it like it's trying to rotate, but just falls short of it, and shines red, green and blue at the same time. The key chain batteries made the lights rotate, but I am guessing the 510 battery is just not powerful enough to get the full rotation going. It looks white on the video, so I put it near the wall so you could see the different colors. To the eye, it is multicolored. I'm excited about this simple mod, since it's my first try, and it actually worked! I don't know how long it will last, I expect I will have to be a little more careful with this battery, save it for party or festival vaping

I am curious as to how long the battery lasts with those crazy big LEDs on there....other than that, awesome job!

I have not used it much yet, I'm trying to save it, so I don't have an answer about how it affects the battery life yet. The LED I put on there has a huge outer casing, but inside are 3 tiny lights smaller than the one already in the cig, and from what I understand, LED's require very little power, so I imagine it should not cut more than a few mins. of battery life at the most. I will post an update once I find out just how long the battery lasts, if it is noticeable that the LED is causing a drain. I could see a problem if the LED was one of the larger ones, but in this case, it's mainly the plastic shell that makes it look big.

I love love love my LED lights, for all of the reasons already posted. I have 510's with red, blue, purple, green and white LEDs. I've replaced the ash caps with crystals on a few. I wish more of the big batt mods had them.

I am becoming obsessed with making an actual color changing LED mod, and have been looking into the laser pointer mod as well, and now I am trying to figure out how to combine the two, so that I can have a stronger, longer lasting battery that is roughly 1/2" wide, like the size of a laser pointer, not a huge bulky flashlight or screwdriver size, with a color changing led on the end. I have a small LED flashlight that looks a lot like a laser pointer, that might make a good "first try" casing, but I am still trying to figure out how to make it all come together. I also found some button style color changing led lights that are about 1/2" wide, so they are a little big for the 510 battery, so I would like to figure out a way to make a battery mod that is small enough to fit these on the end, they would be easy to wire in and don't require much power. I am stuck trying to figure out, if the battery is designed to power the atomizer, how do I rout the power down to the tip, so I can add the LED. Any modders out there have any ideas on this? I don't mind it being a 3.7v, since those batteries are skinny.

Where did you find the crystals?

I've been working on this same problem. I like my laser mod, but I also like the look of the led and the different color options that are available. I have a little electrical knowledge mostly obtained from being around my dad (an electrical engineer), but it's pretty rudimentary so I'd be grateful for any corrections from more qualified modders.

The way my laser mod is wired up, the positive of the battery connects to the body and this runs to the atomizer then the atomizer runs to a switch and to the negative. So my initial thought was to simply run a loop down to the led and back either before or after the switch. You wouldn't want it before the atomizer because of the power that it will pull through the led.
Someone please correct me if I'm wrong.

There is a little room between the battery and wall, but not much. With small enough wire it might be enough to let the battery fit snugly but not be a pain to replace. As for the end cap, I was thinking the wires could end in some type of terminal and the led could simply be plugged in to that. This would be removed when changing the battery. There would then also be the need for some way to mount the led on the end cap.

One alternative way to wire it might be to use one wire and run a parallel circuit. So the positive would come from the battery then to the led and up to the switch on a dedicated wire, while the atomizer would reach the switch through its original circuit. This would require that the resistor be located with the led whereas the other method would allow one to mount it on the pcb.


Mostly these are just questions of how to get everything into a small case.
My other problem is how to make the led fade like a conventional e-cig. Do I use a capacitor? I've searched but not found much info on this.
Anyone have advice ?

Thanks
