What's inside:WOW!!! Really cool, has everything but a digi readout! Love your P-channel touch switch, good idea! Couple of questions ..
100m ohms at Digikey. I've tried every value under 100m and I couldn't get it to turn fully on unless it was a 100m.I do notice that, with a 10M resistor, sometimes it won't work unless your finger is slightly moist .. that explains a lot :) .. What's the 1K used for? I have used my touchie circuit with and without it, seems to work the same either way???
You can use a low current tactile N/C sw from the inhibit to ground. But the chip will continue to draw low ma's while idle.

18350's, one in each tube.The Ruskies make a 2-3/4" metaL cased 12ga, I am sure longer ones are probably available too ????
12ga would be nice. I have 12ga 3" magnum slugs but they are not all metal casings.
Have never seen metal casings.
Stupendous Dave. That's the best homemade mod I've seen to date!
I simply love it. breaktru ROCKS :P
Very Sexy looking.
Maybe a bit heavy for my delicate hands.
Perhaps a couple of 14250's ? I'll PayPal you?
One more question .. you have a digi pot in your diagram, how do you control it? A pair of buttons or ???
This is really beautifully done. If I may ask, what is the part number for the p-channel FET you are using?
The concept of putting different batteries in without have to change tubes or partsThank you V.M.,
is a fantastic way to do it. Just slide the tube in or out, wow. Great work breaktru.

Can I use 100uf 50v caps? Are the compatible?

I've tried and failed to make something like this mod.
This would be my ultimate mod.
Can I buy one from you breaktru?
ETA - OK, I think I read that wrong...in this case you would want to run R2 to Rh (V+ in this instance), correct?
Haven't yet tried it but yes I believe the value of R2 should be between Rh to V+.Thanks for catching that...I really need to learn to not look at any of my technical $#!+ after the kids have gotten me all pissed off. :thumbsup:
Remember, the values are in KiloOhms. So that would be 100 ohms for R1 and 100 ohms for R2.
thank you for the feed back you have saved me ALOT of brain ache. i think I'm going to stick with the 200 ohm pot with the okr and keep with the 100k DP on the 4050c until someone comes out with a DP more suitable with push button control.
On a slightly different note do you think these mosfets would be OK for a tact switch
IRLU9343PbF
Vds 55v
Vgs 20V
Id 20A
Vgs(th) -1V
Once again thank you for your help its been a real help since vaping not only am i saving money feeling healthier i have also found my self with a new hobby :thumbsup:
Okay, this might be a dumb question, but do you have to insulate the outside of the switch from the tube? If you used two different contacts instead of one inside the other, would you insulate both? I know they have to be insulated from each other, but from the body? Excellent mod, by the way, but it's a long way off for me.
Breaktru,
I'm getting ready to build this board for my 1st. mod. You diagram shows batteries in series. I'm planning 2x 19650 Panasonic NCR18650PF 3.6V 2900mAh. Question; can I wire them in parallel? would make usb charging easier.

I think this P-Channel Power Mosfet IPD90P03P4-04 (http://www.mouser.com/ProductDetail/Infineon-Technologies/IPD90P03P4-04/?qs=sGAEpiMZZMshyDBzk1%2fWi9Xn%2fBYY8cyRypmGTibqaKg%3d) would be better suited as it has a Low Drain-source on-state resistance RDS(on) rating of only 4.5 mOhms
Gate threshold voltage VGS(th) is: Min -2.0, Typ -3.0 Max -4.0
