I thought I would share my simple design for a fog generating machine, I made this a few years ago as a pesticide doser. It might be of interest to those of you making a PI based Halloween special, just dont add the pesticide!

 

I could not find any cheap units when I made this a few years ago, maybe there is a cheap off the shelf solution now? but I still prefer using things built than bought.

This unit just requires water and 24v to operate, no chemicals needed.

I look forward to watching the Pi Halloween projects,
