Stickish boxmod idea, multivoltage

[DJ Colburn]

Howdy y'all!

Thus far, my only experience has been with 3.7v vaping. But i know that 5v (or higher!) is a very popular option. So I'm thinking... why not make a single boxmod that can do 3.7, 5, 6, and 7.4? I hear that the 14500's are about AA-sized. So if we can take a 3 or 4 AA sized box and two 14500's, with a nice nest of regulators and switches, we can have a 2-battery system that goes all the way from 3.7 to 7.4. I think the hardest part of this would be whatever mechanism switches the batteries from running in parallel for the 3.7 to series for the higher voltages. It's been a while since I've done anything electronic, so advice would be quite welcome!

Peace!

Nice to meet you,DJ Colburn.
mod that the power conditioning is possible has been opened to the public, and refer to my blog, please if it is good though the approach is different from the method for which you hope.

There is a post on a 3.7 and 5 volt mod in the modders section.

What you want is one of these, plus a multi-position switch with resistors (or potentiometer) to select the voltages you want.

Superfluous post (sorry)

maaaaaaaaaaaaaaybe I've been out of EE for way too long. I'm reading the spec sheet and thinking to myself, "WHAT?!" Basically, I have no idea how that thing is supposed to work. Time to go back to school, eh?

/me hits the books

See the schematic on the lower right hand side of the first page of the data sheet? That's how you wire it up. You need to calculate the resistor values you need to get the voltages you want. Lets say you make it easy on yourself and just want 3.7, 4.3, 5 and 5.5 volts. If you make R1 100k, you need 50k, 40k, 33k and 29k resistors and a 4-position slider to switch between them.
