I'll say once again, always follow the wiring diagram in the OP, not the parts list in that post. The wiring diagram is externally linked and always kept updated. I can no longer edit the OP to change the parts list to correspond with the wiring diagram. I wish I could, but that option is not available and hasn't been for months and months.
I know there's a lot of posts in this thread, but if you take the time to read them you'll find why we changed the pull-down resistor from 7.5K to 4.7K. You'll also find out why we now connect +/- sense. You'll also find lots of tips and techniques of how modders did their builds and the parts they used and links to those parts.
Question? How can i test resistance of a pot? I have i couple lying around (from dead ego-c-twist, and spinners) that i might want to use if i can fir my build.
You can test the resistance with a multimeter. Once you know the resistance, then you would use "parallel resistor formula" (google it) to determine what you need. You don't want to be too far off with the pot to begin with, because adding a parallel resistor changes the linearity of the pot.
Here's the blue voltage reader I ordered but they are all over ebay just search for blue 0.28 voltmeter. The only one I found in the US was 15 bucks which is beyond rediculous. And I would buy a good quality pot, bc resistance isn't the only factor. You want accuracy as well.

yep, the extra 350ohm resistor for the 470ohm pot goes between wiper and the leg with the 220ohm resistor (and snip off the 3rd leg of the pot).
I bought a box of 50 pots long time ago, I've used a few, but I have 40+ left. I want to keep ~10,
so plenty available. PM me for contact info if you want some.

Totally out of subject... but all these signature banners stating "ex-smoker for blaablaa days, $xxxx saved...etc..." Yeah, I'd like a more realistic one stating the saved money as "at least $xxxx spent on vaping gear!"Because I don't think I've really saved any money, it's all gone to something else.

holy smokes.... or vapes that is.
Read a lot of this thread today; so confused, lol. I think i'm gonna have to start with a unregulated box mod for my first one.
i'll be back though.

I'm sure anyone without an electronic background is confused when they first start reading about this build. My head felt like it was gonna explode the first time I read through this device. I recognized the words as english but they might as well have been chinese. Just take your time and get a solid understanding of the parts, what they do, and only then start building. Thats what I did, I researched this build for several weeks before even considering buying my first part. Take your time with it, it's so worth it because it's really neat to vape on such a beastly device that you built yourself. Check out the no idle drain circuit diagram on page 33, it's only about 3 dollars worth of extra parts and about 2 minutes of extra work and you get the added benefits listed for that build. I hadnt soldered in over 20 years so if I could do it, just about anyone can. IMO the hardest part, once you understand what your doing, is fitting and organizing everything into the enclosure. Oh yeah and many of the parts are dirt cheap so try to at least by double what you need for as many of the parts as you can besides stuff like battery sled, enclosure. And finally if you do decide to complete this or any of these builds, all I can say is welcome to your new addiction!!
Heck with an unregulated build you would still need a mosfet, to take the load of the switch.
Finding a switch that can handle a load is going to be tough, and it would be huge.

We'll be repeating this all the time...
Mamu, perhaps you can add some red text into the image itself stating that the parts shown in the image are the ones to be used and not the ones listed in the text portion of the post.
