a few notes just in case, you will need an air compressor to run the pneumatics, your laptop must be running windows to operate vsa ( not mac )

also if you know how to solder or wire then you could just open up the fog machine remote and splice in a 120v relay so that you could trigger the fog machine by plugging in the relay, so you could plug the relay into the dmx relay pack and not need a dmx controlled fog machine.
