The video tells about a homemade smoke machine, a power of 200 watts, made from improvised materials. Related article: I decided to shoot a little smoke when shooting one of the rollers. I wanted to use tobacco, but I was afraid that it would be difficult to get rid of the smell afterwards. If you have two power sources, then such a smoke generator can be built in a couple of hours. But if you use one power source, you will be deprived of the possibility of operational density and the speed of the flow of generated smoke. For the rapid control of the amount of smoke and flow velocity, a simple fan control unit was built. The smoke generator works as follows. Glycerin is poured into the evaporator chamber in such quantity that it can be absorbed into the cotton wool. After warming up the spirals, which takes 5-10 seconds, glycerin begins to evaporate. The fan through the air duct pumps air into the evaporator chamber, which mixes with the glycerine vapor and is discharged through the silicone hose. This hose allows you to send smoke to the desired part of the scene during photo-video shooting. Part of the glycerin settles on the inner surface of the hose and when it accumulates a lot, it can be drained back. The drawings and circuit of Smoke Machine can be downloaded from the “Supplementary materials“ of article.
