I have used any number of different
methods of animation when building model railroads including
movement, sound and light. I have not, however, used
smoke... that is until now.
The fairly recent advent of smokeless cigarettes, also
called e-cigarettes, e-cigs or vapor cigarettes, has
provided an opportunity for us to make small, inexpensive
and quite impressive smoke machines.
I have been doing some experiments
and have come up with a fairly simple method to create a
good bit of smoke that can be turned on or off at will.
