PopSci How 2.0's

I'm not that tech savvy but you would think they would be a little more clear with their directions. Has anyone done this flashlight conversion. I have all the parts but don,'t understand the directions they are a bit vague, can anyone help?

First off there is a link in the article about the flashlight to Nuts n Volts, here at this link and secondly, despite how vague the directions are at The Popsci site there are 3 pages of instructions there in addition to the links they give.
