Just your basic VV mod in an Altoids tin, but with a different skin. 
Kind of a nod to the first e-cig I tried a little over two months ago, and what got me started on all this. It's a handful for sure, but not too big for me. Nice heft.
The board is a LM2596 step-down board bought off the 'bay after reading one of Mamu's posts. Battery holders also bought off the 'bay and then modified, as they were too tight as-is. Two 18650s.
I about lost my mind when the thing wouldn't work and wouldn't work... etc. etc. until I finally snapped and realized the battery holders must be for a flat-top battery. A little blob of solder in each + contact, and rock & roll.
Voltage set at 4.18 volts unloaded, which I'm assuming will get me real near 4.0 volts loaded with a 2 ohm carto. A decent amateur radio operator might be able to figure this out easily, but well... I'm guessing.
Next time: 1) Work on neatness, and 2) Yes, it's as top heavy as it looks.
Not much more to say, so... pix:
