I know you can't see sh*t in this video, but I finally got it working stand-alone. No computer involved at all.

As I say, it looks feeble through the camera, but from where I was it looked great.
First time with a Hazer, rather than a fogger too...
A big thank you to all the people on here that helped me to put this together - especially Genesis and mixedgas.
THANKS!!
