Dimming a 6-Wire Buckpuck with Arduino?

Hi. I've been asked to make two lightsabers for use in a performance at the Budokan, of all places, and brightness is the top priority.

The colors are green and red. For green, I'm planning on using a Luxeon V. For red, it seems the brightest LED that will work in a lightsaber is the Luxeon III.

I plan on using two 14500-type (3.7 volt) TrustFire Li-Ion batteries for the green Luxeon V, and probably four aaa 1000mA Ni-MH batteries for the red Luxeon III.

For the green Luxeon V, a 700mA Buckpuck seems like a good idea. And a 1000mA Buckpuck might be good for the red Luxeon III.

I'm thinking of using 6-wire Buckpucks (the 3023-D-E-700 and the 3023-D-E-1000), and I'm wondering if the Arduino can use the REF and CTL wire leads to create effects such as shimmering, fade-in, fade-out, etc.

Oh, and the performance is just seven weeks away. :o

Any advice for this n00b will be greatly appreciated.

Hello, I am also interested in using arduino to control buck-puck drivers. Despite there being no replies yet did you make any progress?

Here is a related topic.

Sorry, Patrick. I decided to go with an entirely different lighting system, but I am still very much interested in using Arduino to control a Buckpuck. I'm tempted to say, "It shouldn't be that difficult," but practically every time I've said that, I have found myself stumped. I'm still trying to work out how to use MS Timer and/or Fuse to get Arduino to do several things at once. :-/
