So I've actually had a little bit of progress on the fear gas dispenser. I purchased a Kanger Subox Mini Starter Kit last week from "Top Vape Mods", and it'll take about two weeks for it to arrive. I got this one after the twitter admin for Top Vape Mods recommended it, on account that it can hold a lot of juice, and has plenty of vapor production. (Side note: a couple days after buying this, I passed a local vaporizer store. D'oh! The good news there is that I'll be able to go by there before I get my vaporizer to see what they think about the setup. I haven't actually talked to anyone who does the vape thing about my idea. )
Most of the parts pictured were purchased at Fry's Electronics, with the exception of the plastic bottles, which I got from Hobby Lobby. The picture to the right is my current plan. I'll hook the batteries up either by series or parallel, to either double capacity or voltage (not sure which yet). The battery will connect via power y-joint to the two fans. Here's the tough part: my goal was to get a small plastic box to house the fan, but I came across some plastic bottles, and had the idea to take two, cut them in half, and squeeze the two halves together (the dotted line is a cut to allow one half to slide into the other half), with the fan in the middle. This would create a sort of wind tunnel. I'll then make small holes in either end, and pipe the smoke in via vinyl tubing connectors. The bottles I got were just a few millimeters too small, and my attempt at heating them and expanding them just didn't work. I'll go back later today to pick up the larger square bottles I saw last time. To fill in the extra space, I'll wrap paper or something around the sides of the fan to thicken the walls up. I'd rather do that than use a Dremel to modify the fans and risk breaking them.
Once I make more progress, I'll post some more.
