Easy OKR-T VV mod

bstedh;3302009 said:

I thought I would share my research and post an easy VV that just about anyone who can use a soldering iron could put together.

A lot of this came from the evercool thread and work on my own VV. http://www.e-cigarette-forum.com/forum/battery-mods/114901-evercool-variable-voltage-mod.html

I did not include a box or other body as you can put this into whatever type of mod you can cram it into...

You can also add an LED or other bells and whistles but I wanted to keep this as simple and strait forward as possible.

Edit: You can also use any 3.7V batteries to fit the mod body that you are looking at. The higher the mah the better. The 14500's I used where a compromise due to the body I had to work with.

Any guru's out there please chime in with simple suggestions or modifications or anything I may have missed. Especially with regard to the switch.

Here is a link to the one I put together. I have cleaned up the wiring from what I posted but it gives you a good Idea of a finished product from this idea.

Shorty 510 Extension and Connector $6.99
I personally like this as it has a nut to help secure it to the mod body without glue or epoxy. However you can use a cheaper connector. Which ever connector you use I recomend removing the center pin and insulator for soldering so as not to melt the insulator.

Ultrafire Protected 14500 Battery, 900 mAH $4.79

Mini Pre cut Interconnect Circuit Board $0.99
This is not necessary but it would make connecting to your regulator and resistors much easier. Just cut it down to the size you need. One piece for the regulator and one for the variable resistor. this will also help to mount them in your mod body.
