I'm sure someone in this forum has done this before, but I searched through 15 pages of search results, and didn't find a solution.
I need to have
smoke coming around the edges of a working door, to simulate a fire in the next room.
Off Off Broadway (no budget). I have my own ADJ
Fog Storm 1700 with a working
DMX Remote. The fogger works, but I need to direct the
fog to the cracks in the door, and I need to be able to control it from the booth.
I tried channeling the
fog into a couple of small rubber tubes, like those used for fish tanks. The tubes had to be about 10 feet, but I couldn't get the
fog all the way to the end of the tubes.
HELP! Please.
@kenact A few thoughts for you.
1; Think in terms of getting an airflow established then use the machine to inject
fog into your already established air flow so the air will carry the
fog along for the ride rather than having to depend upon the fogger to provide all of the propulsion for the entire distance through the small diameter tubes.
2; Larger diameter tubes will offer better air flow with less restriction.
3; Consider a funnel with a fan behind it establishing an airflow into your tubes. For example, consider a ten or twelve inch diameter funnel fitted into as large diameter tubing as you can deal with. Make the joint between the funnel and your tubing air tight. Place a ten or twelve inch diameter fan four to six inches away from the mouth of your funnel. Turn the fan on and leave it running. Direct your fogger's exit to expel
fog into the gap between the mouth of your funnel and the front of your fan. You'll need to experiment with the duration of
fog and the lead time required for it to follow the established air stream through your tubing. Put your grade eleven physics classes to work for you, best wishes and luck.
4;
Purchase appropriate connectors and cable and solder up a suitable extension cable for your fogger's remote. Your remote will likely work up to 100' on 18 or 20
gauge copper cable. You're only extending low
voltage control signals
NOT the
power for the fogger's heater or pump. There's no need to
purchase connectors that match those already on your ADJ fogger. Think of it this way: Cut the cable on the remote approximately a
foot from the
connector. Strip off 3/4" of the outer
jacket and note the quantity,
gauge and colors of the cable's inner conductors.
Purchase two mating pairs of connectors designed for enclosed secure attachment to cables, NOT connectors designed for chassis mounting. Install a female
connector on the 1' length that plugs in to your ADJ fogger. Install a male
connector on the remainder of your remote control's cable. Check all of your work for good soldering or
crimping with no excess bare conductors to possibly short.
Plug everything back together and fully test. Assuming everything is good, install two more mating connectors on your 100 feet of extension cable, fully check your work and get on with life.
EDIT: Elaborating on
connector choices. Rugged, durable,
latching connectors which
grip solidly on your remote control cable's outer
jacket are what you're looking for.
Ideally chose connectors which DO
NOT mate with anything else in your building. All too many people operate on the "If the
plug fits it MUST be right" theory so consider the following when choosing your connectors:
Your connectors are only handling low
voltage, low
current, control signals.
Connectors to
AVOID and
why:
Connectors normally associated with higher voltages and currents such as:
Household parallel blade, grounded and non grounded.
Stage pin connectors, grounded and non grounded.
Twist locks of all sizes and ratings.
XLR-3; Commonly used for
microphone and
line level audio (And economy
DMX).
XLR-4; Commonly used for intercom headsets.
XLR-5; Commonly used for
DMX.
XLR-6;
NOTE: XLR-6's are manufactured in two
NON INTERMATEABLE configurations.
XLR-6's in the
Switchcraft compatible configuration are often utilized for dual
channel Clear Com systems.
XLR-6's in the NON
Switchcraft compatible configurations MAY be a good choice for you.
XLR-7's MAY be a suitable choice for you unless you're already employing them in your facility.
Speak-ons and Powecon's of all flavors should be avoided for this application.
@kenact Is this making sense to you so far?
?
Toodleoo!
