    Need good 18mm or smaller switch

    You want a big switch and you got a small box to put it in. The 2 amp switches are too deep to fit. If you use a mosfet it in turn acts as the main switch. The tactile switch turns the mosfet on. But it does it with a voltage and just about no amperage to speak of. So mosfets will let you use...

    Need good 18mm or smaller switch

    To fit in that small space and also big on the big side these switches here are the only ones i know of. JF15CP2H NKK Switches | JF15CP2H-ND | DigiKey But you going to run into the same problem as the ones in the box if you dont use a mosfet with them. They are rated @ 50mA just like the small...

    summer is comming. so is the "Floatie" mod.

    Bad thing about a waterproof mod is if by some freak chance the battery goes terminal , you got your self a hand grenade. Designing a plug to blow out at a low pressure might be a good solution.

    You got to run those with a mosfet or a control pin on a regulator they are only rated @ 50mA. Looks like you would have room for a fairly big P channel mosfet.

    Need good 18mm or smaller switch

    Thats the manufacture web site. If you use the configure button on the switch page it will show you places that have them in stock. I just took a guess but i picked a PV2 series flat with solder lugs and polished stainless steel and got this link to the switches for sale. E-SWITCH - PV2F240SS -...

    can someone give me a link for a vv box mod build guide?

    This is my favorite http://www.e-cigarette-forum.com/forum/battery-mods/114901-evercool-variable-voltage-mod.html Edit never mind i didnt read the last part of your post. Your going to need a mod with a intelligent chip or a digital potentiometer to do what you want. I believe breakthrew has a...

    You just have to look at the trace and follow it from the feedback pin to where the pot is. More the likely the center pin and a outer pin are going to go to ground then the one outer pin left will go to the regulators feedback pin. So in all likely-hood it would be the pin closest to R1. It is...

    I would slap it on the one that goes to the regulators feedback pin. Thats the safe bet anyways.

    Your Welcome Tom If your slapping a trimmer right back in the same holes there is no good way to add a resistor in series with the pot. Puts you back in the same boat of not wanting to solder a 0604 smd resistor. Now say if you were going to put a real pot in the ones you can slap a dial on...

    510 battery connectors

    I hope the center piece is not going to be stainless your also going to have to have the case grounded. It would be easier to get a date with Angelina Jolie then get solder to stick to stainless steel. I guess maybe if you used a silver bearing solder and a torch you might get it to stick but i...

    Should be somewhere around there. But Specs on these chips are not always spot on. I just got a chip today from China ( not the LM2596's they are still not here ) it is supposed to have a adjustable output of 3 to 25 volts. Real life it went from 5 volts to 17.3 volts. Just modified it to go...

    Do regular AA batteries work in Mods?

    double AA batteries cant produce the power needed to vape. They are also low voltage compaired to li ions that are 3.7 nominal volts. AA batteries are 1.5 volts. Could be there is a shortage of tree's. But most likely is they are hand crafted and not mass produced. There is no machine spitting...

    are cr123a the same as 18350?

    here you go a helpful link to battery sizes List of battery sizes - Wikipedia, the free encyclopedia

    are cr123a the same as 18350?

    No they are 3 volt nominal voltage not 3.7 volts. I believe they are also the same size as cr123a's

    are cr123a the same as 18350?

    No not quite the same cr123a are 16mm in diameter and 18350's are 18mm in diameter. cr123a = 16340

    Not my math it is from the data sheet. Really R1 should be a fixed resistor between 240 ohms and 1.5 k ohms to keep noise out of the feedback pin. At least thats what the data sheet says. But as WillyB pointed out you could run just a pot on the reg.But it should give you the full range of the...

    Micro-Controller Mod

    WoW Dude , seriously Your really going to come up in here and tell breakthru his creation is not correct because he used a regulator you dont like. I mean come on what have you built, what you got to show us. i mean even if you were right , which your not by the way, that is pretty damn...

    just to add to the above a bit maybe make it easier to understand We know bj43 's reg has a top end output of 25 volts we also know it has a 10k pot. so we take the formula (R2 divided by R1 +1 ) x 1.23 = output voltage. R2 the Pot is 10000 ohms. If we plug in 500ohms for R1 we have 10000 /...

    If in fact the R1 resistor is 500 ohms a 5K pot would give you 1.5 volts to 13.53 volts . A 1k pot would give you a range of 1.5 volts to 3.69volts . These modules come in a few different max outputs that i have seen on Ebay. 20 volts 25 volts 35 volts 40 volts. The formula is ( R2 divided...
