...how to make a fogroom.

Its  not quite like Twin Peaks, but its pretty good!

The fogroom is a project which involves 144 ultrasonic transducers, 6 solenoid valves, two dedicated control boxes and good old tap water.

The draft control system was originally intended for a “rain room” project, however it was easily repurposed.  

A lot of the early prototyping involved finding an easy to maintain and control fog generator system.  There are a lot of commercial fog generators out there, however few seemed to be geared for our purposes.  Rather than purchase a commercial set-up, we went and obtained the transducers that are commonly found within these commercial systems.  Some experimentation was then done with various methods of pushing, pulling & conducting the fog.  It needed to look and flow like real fog.

The test version was controlled with MAX/MSP for DMX lighting, Audio and playback.

The installed version utilized a PLC and show controller combo as something a little more robust was required for this 365 day a year attraction.
