Cold Smoke Generator (BBQ) 1/2

This is a brief overview of the cold smoke generator that I just finished building for my smoker/BBQ. It's mostly made of aluminium extrusions, pop-riveted together. The hinged ash-cup on the bottom is my own idea, but the basic functionality of the smoker with the aquarium pump is based on designs I've seen online. The pump is a "5-gallon" pump, I assume that means per hour. It seems to be good enough, but I might upgrade to a higher-volume one at some point.
