How small can a PV be ?? Can anyone do better than this?

[kinabaloo]

I love this from KNutselPeter in another forum: How small can it be? - *E-Cigtest, the ultimate electronic cigarettes review site* - Le site de la cigarette électronique

Based on the case and usb plug of a usb card reader, it includes a tiny rechargeable battery. Plug in usb socket to charge; charge lasts one ccartridge (5 cigs equivalent).

I've seen these usb card readers in the UK's Poundland shop.

I wonder if anyone here could go one better and make a new 'world's smallest' ...

Wow - I'd love a tiny little thing like that! (I'd probably lose it in a week, but still)

Perhaps the led could blink on one per minute to help with finding it

With a suitable power supply it could be portable too.

kind of like a find your remote alarm but for you usb of awesomeness

KNutselPeter is the original Modder. He has thought up everything we do here, years ago. That is a good mod but honestly its using a the same battery inside all our cigs. It just has a button. So I think what have now in the minis is the smallest. What we are after is long lasting switches and battey.

This is one of my favs of his. Cigarette Case - *E-Cigtest, the ultimate electronic cigarettes review site* - Le site de la cigarette électronique

A cartridge, atomizer, a switch, and 2 or 3 LR41 cell batteries should give you enough power for a cartridge or 2, assuming you don't care about recharging. That's probably the smallest portable one you could make, but I don't really see the point, unless you like wasting batteries.

I'm waiting on a couple DSE atomizers, but that is my goal--compact performance. My last one is getting close.

Well, the small size is not necessarily the aim - it is a matter of re-thinking the design by pushing on a boundary; this might lead to an innovation that's not about size.

The design I posted uses rechargeables. Furthermore, a small design uses least materials = least "wastage".

Together with a power pack, that design also allows portability without a wire link while actually vaping.

ok, smallest theoretical design i can come up with would be .8 inch wide, 1.5 inch long, .8 inch tall... considerably smaller than the one above.

supplies needed would be:
.01mm nichrome wire coil
small kevlar wick
ceramic pipe that fits loosely over the nichrome coil
8 ms920s button cell batteries
charging circuitry (to keep it small, timer would probably be better than full charge circuit)
usb connector
surface mount switch

ms920s specs
3.0-3.2vdc @ 11mah
9.5mm diameter x 2.1mm height

2 stacks of 4 in parallel would provide 3.0-3.2vdc @ 88mah
2 stacks of 4 in parallel + series would provide 60-6.4vdc @ 44mah

size would be 19mm x 8.4mm (add a lil for wiring or tabbed connection and insulators) 20mm x 9mm

insert nichrome coil into ceramic tube, leave wick long enough to run through coil and outside tube

that should provide a drip only device capable of 100 or so puffs, rechargeable from any usb source
