The Pipe Bomb - My new e-cig mod

[Frankie]

The most beautiful mod ever was made by the great innovator himself and uses this: DealExtreme: $3.32 Shock-Your-Friend Pipe (Practical Joke) . When my first two batteries die (almost 7 weeks hard work in them, should be soon), I would like to use this as a base. But I have no idea what battery to place in the pipe. Anybody help me out with this, please?

I would also like to know if higher "mah" means better performance or just *longer* performance. I have a cigar that is not really great performer. It uses 350 mah AA separate battery. If I buy higher mah same form factor, the vapour etc. should get higher, too?

Thanks in advance.

Higher mah means longer performance. The mah measure is how long the fully charged battery would last in hours if a steady current of 1 milliamp was drawn from it.

Anarch, the clicky switch is not very practical for ecig use. I picked up a few pushbutton switches and a few tactile switches from radio shack. I've got a message out to a switch company trying to buy a few switches that will be perfect for the ecig application. They are small tactile switches but they have big soft pushbuttons on them which is exactly what I want to use. For the flashlights the method is different for each kind of light, but the concept is the same. the clicky switch shorts the battery spring to the frame of the flashlight case whenever it's in the "on" position. You'll need to take the endcap apart and figure out how to hook up a normally open switch from the spring to the flashlight frame, so when you push the switch it shorts the negative battery spring to the frame. It's hard to describe exactly how to do it because each light is a little different. The clicky switch on these has a long metal tab that makes contact with the spring, and one on the side that makes contact with the case. The easiest way to get both sides hooked up to a switch is to click the switch in the off position, put a drop of superglue inside the white plastic button so it remains off for good. Then you want to solder a wire to the pad that makes contact with the spring and run it to the outside of the case making sure it never touches ground. That's your negative. These cases are aluminum and can't be easily soldered so your best bet on the second wire (ground) is to take the small hole that was used for the wrist strap towards the bottom of the casing and drill it out to make just a hair bigger. This will remove the paint and ensure you have good contact to ground. Then you can wrap a wire tightly around the hole and solder it all the way around so it makes a good tight contact with the case. The 2 wires you just set up will be soldered to your switch. Make sure you ohm everything out as you go, you don't want your spring wire grounded to the case unless the button is pressed. I have a larger switch on the end of my pipe bomb style battery and it works fine, but I do prefer the tactile flat switches because I like the switch being on the side of the case as opposed to the end. Once my 14500's arrive I'll make sure it works as expected and take some pictures to share with everyone. The Husky 2-Pack flashlights are 2 for 7 bucks, and they really are perfect for what we are doing.

Here is a good size comparison between the 14500 and the 18650. It's much more pocket friendly and lighter. I'll still keep the larger one and use it around the house because the battery life is just outstanding. It's been 4 days now on the same charge with no sign of decreased performance. At 20 times the capacity of a standard ecig battery, the 18650 should provide about 40 hours of use (averaging 2 hours per standard battery X 20). The 14500 version should last about 10 hours per charge, which is still 6x the capacity of a standard ecig battery. I'm willing to sacrifice some capacity for size, because I don't really need a 40 hour battery. If I ever go on a week long camping trip I'll take the 18650. I could vape an entire 10ml bottle with one charge I'm sure of it. lol - BTW I will be posting battery life tests for both mods once my 14500 batteries get here. I'll charge one up all the way and just that one until the battery dies, then I'll test the other one. I'm guessing 5 days on the 18650, and 2 days on the 14500 with normal use. If you use it constantly all day long, the 14500 would need to be recharged every night but spare batteries are cheap so you can keep a few charged and ready to go. The battery life of the 14500 should be comparable to the screwdriver. I challenge anyone out there to do a "puff count" with either of these two mods. haha

QFT. My 2500 mAh battery will last longer than a 110 mAh battery because, while the actual voltage will be the same (2.7v-4.2v) there's more capacity for power over a longer period.

If it helps, think of mods like the PB and SD as adding an extra large gas tank to a Yugo. It's still a Yugo, it'll just go farther between fill-ups.

You electronics pros correct me if I'm wrong but, won't a higher capacity battery also deliver the higher voltages for longer? IOW, if my 901 atomizer works really well at between 3.7 and 4.2v, won't the higher cap batteries deliver that higher voltage for a longer period before dropping off?

here are some new pics of a soft touch switch installed on a flashlight mod. These things are great! The buttons are easy to press like you would find on a remote control. I'll do a review on this mod once my batteries arrive. For some reason in the pictures, the heat shrink tubing I used to mount the switch appears much lighter than it is in real life. When you look at it in person it looks much better because the color matching is a lot closer to black.
