Jay,
There are inexpensive christmas light sequencers available. They generally use 3 circuits with every third bulb on the same circuit. I had one a few years ago that had a switch to select chase, random or all on, and a knob to vary the rate. Cost no more than 3 or 4 bucks and came with the lights. That is a little bit different than the rabbit, which has only one light on at a time, so it may not achieve the effect you are looking for. A possible low tech solution would be a motor driving a cam that closes a series of microswitches in sequence...easy enough to produce by someone with a little bit of mechanical talent and not much electrical know-how. A higher tech solution would be to use electronics consisting of a programable logic device and a set of solid state switches to switch the current. Could also be done with a computer with a relay card plugged into it, but would need a little bit of programming to make it work (such relay cards are available from electronics firms like Jameco). The computer solution would be a bit of overkill, but could be done with off the shelf stuff.

(Background: Over half of our guests come in the "wrong" door to our lobby, which leads more directly to the pilot's lounge than to the reservation desk. As a result, we've often got people milling around looking "lost" in the pilot's lounge. These chasing lights would "lead" them to the correct area, and be really cool looking, too.) So, I stopped at the local Rat Shack, and found the perfect little 12 volt blue lights, 1/2 inch in diameter. (Blue would be a bit toned-down from white strobes!) It would be a simple matter to drill 1/2 inch holes in the ceiling tiles, every 12 inches or so, and push them through the tiles from above so that only the blue "dome" was sticking out through the hole. I think 12 volt lighting would be safer in the ceiling than 120 volt Christmas lights, as a couple of people have suggested... Here's the problem: How to sequence them? The guys at Radio Shack had NO advice at all -- they were all stumped. The lights should flash sequentially pretty fast, but I think they'd look pretty stupid if they weren't coordinated properly. I'd also want to incorporate a motion detector on/off switch, so that they weren't running all the time. Anyone got any ideas? Are there affordable electronic "sequencers" available? Is this something RST Engineering could build for me, Jim? Thanks! -- Jay Honeck Iowa City, IA Pathfinder N56993 www.AlexisParkInn.com "Your Aviation Destination" -- --Ray Andraka, P.E.
