fog machine

[gahh]

i have a question about the hook up of a fog machine.  i am using prop 1 and rc-4.  i want the fog machine to spray a certain amt when controller activated, but i am unsure how to wire this correctly.  I have a multi functional trigger for the fog machine.  It can be used manually or used as auto control.  I am using a plain 400 watt fog machine.  I have hacked into the trigger and soldered lamp wire onto the manual button part of the trigger and hooked the other end of the wire into the rc-4.  The fog machine will stay plugged into in order to keep it warmed up.  The plan is that when triggered, the manual button will activate and set off the fog machine. I have not tried this as I'm not sure if will even work or even worse burn up the controller.  Please let me know if this is correct. 

Thank you

 You can do so if you use the prop 1 to control a relay have the coil leds to the 12v termanal say p4(+) and then the other on ground(-). Then solder two wires from the mannual push botton the the contacts of the relay. then you  need to knw how long the run time of the fog is and then the time it takes to reset (rehate) and thats it.

test it with a simpel code:
  fog pin5

main:
pause 7000     ' warm up time
high fog           ' start for
pause 400       ' spray time
low fog            ' stop fog
goto main

The fogger remotes that I've seen are switching 120VAC so you should be able to connect the wires you soldered to the button directly to a relay terminal on the RC-4; when that RC-4 channel is active it will behave as if it is pressing the remote button.  So, it seems like you should be fine; just need a program that triggers the RC-4 (best to do it serially) and runs the fogger as you need for your prop.

The EZ timer attachment would be good for this.

The code attached is a passed code that i have used myself in the past with a fog machine(To test). Connect the fog machine to k1 on the RC-4(RC-4 should be connected to  pin7), use the wires that activate the fog manually. The timer option on you're remote is not necessary for this, the program can be modified to allow more or less fog depending on the pause you set before it turns off. I hope this help's you out gahh
