Is this possible

   Depending on the voltages you're using, you could use a PIR detector from a yard light (motion detector).

	Not whizzing, execellent point. I actually totally forgot about that. You could feasibly(sp) just build out a API that could be trigger during a show by the scheduler. that trigger then could execute a set "sequence". should be easy to write. we'll have to see what type resrictions will be applied to the developers.

	May be just whizzing in the wind, but lets not forget the coming Plug-In options for 3rd party developers. Its possible that a plug-in app could be written to do just this.

	Any suggestion on what I could use as a trip mechanism?

	I'm just thinking a separate program and network since a passing car is a bit random as is the speed. Trying to tie that into an existing sequence might make it a lot trickier - then you start messing with the timing of the sequence - how should that affect the way the music plays...? Multiple trips are great and as long as you only have 4 sections, it's probably the simplest solution. But as the number of channels/trips goes up, you have additional expense. I'm completely guessing about the nature of your display, but I'd like to see at least 8 or 10 channels (perhaps an entire 16 ch controller?) dedicated to this feature because as you get smoother effects as the channel count increases. Also, being able to put the trips upstream 20 or 30 yards would be nice since you can "lead" the cars by a little - would make it more obvious to the driver who might otherwise miss the effect if it's right next to the car. In the end, it could be an expensive effect. Keep channel usage, extension cords (how long is this run?), and trip mechanisms in mind. All the same, it would probably turn out very cool if you have enough channels and would be fun to figure out. :D

	do you want to have this running during a show with a dlight board? like having a an arch in a str8 line across the top of your fence? that follows at the pass of the car. If you don't plan to have this operate with your show I would go with something that has to do with the relays and a simple on off feature as explained above. You could still run this off the same computer but use Vixen to drive this part of your display. I have an 8 port "kit74" (google it) that would actually work well for this. it would require a software build out maybe. I haven't seen what Vixen can do these days as I am completly satified with the way Aurora runs my show. But you may want to look at it as a solution. Slink

	I put this in the off topic, not planning on using sequencing software.

	But ...... My controllers are using the same network and are daisy chained. but I see your point. you still got to remember that the scheduler is actually just executing a index or playlist it does not do control anything other then the order that it plays in (hence dont make any changes to the order while the scheduler is going. But .... You might be able to have it schedule and execute a preplanned seq (a fade that goes the length of your front fence) when triggered? Whats wrong with my thinking? Slink

	Wouldn't it be easier to put 4 laser tripwires that triger a single section?
	Fine. You're so smart you rig up the lights. D-Light users Unite!

	Remember you have multiple USB ports that can be used, so there shouldn't be problems with ports already occupied (I think I remember that each can handle up to 256 devices at the same time...?). If the speed program is ran concurrently with Borealis (shouldn't be a problem), I think it can be done if it's ran on a different "network", as can be done currently. You'd need a separate USB dongle (network) for the speed program. If you can't come up with an actual radar gun solution, then you could bounce a couple lasers across the road and determine speed by the time elapsed between the signal getting interrupted. (Actually, this might be more precise since you'll know where the car is in addition to how fast it's going, so you'll have better control of when to start the sequence.) After determining the speed, you can calculate the rate at which to send the light signals out the USB port. You could probably write that routine such that there is a fixed-length pause between each command sent out. The speed of the car determines the length of the pause.
