Presumably someone who was that susceptible to flashing lights would know
enough to stay away from Las Vegas, or Times Square, or the Ginza district
of Tokyo, etc. Actually, there is so much light there that I would think all
the flashing tends to even itself out.

Back in the late '70s I remember reading in an Air Force safety magazine
about a pilot who was watching the setting sun through the windmilling prop
of a C-130. He had a seizure on the ramp. He never suspected that he had
epilepsy.

Can someone have a seizure watching the wheels spin in the slot machines?

Do slot machines even have wheels any more? I don't know; I haven't taken a
close look at a slot machine in 20 years.

Only on old machines, all the new ones are video displays, though it will
be years before all the mechanical machines go away.

The trend seems to be away from the classic 3 wheel machine to more
interactive games.

The guys at most radio shacks these days can't change the batteries in a
flashlight without a training video and a map.

25 years ago, I would have grabbed a 555 timer, a 4-bit counter, and a
4-to-16 demux out of my TTL collection and built a sequencer in an
afternoon for about $10 in parts. The breadboard it was built on would
have cost more than the chips. Of course, if I told you I was going to
use it to drive a series of blue LED's, you'd look at me like I was nuts
(everybody in those days knew it was theoretically impossible to build a
blue LED).

I wish I knew were all that stuff went. I can only guess it got tossed
when mom sold the house a few years back.

Jay:

Take back those expensive RS bulbs and everything else. Then find
a store (possibly online) that sells "chaser lights". Any
theatrical shop carries them (but will likely be more expensive)
or the local hardware store.

There are also very expensive versions that you can program to
do whatever you want.

Are these 110 volt? Shouldn't I be concerned that they will generate too
much heat up there in the enclosed ceiling? (Not to mention, having the
bulbs sticking through the foam-core tiles?)

I missed the original post on this one...can anybody repost it for me?

And to those of you who want to use microcontrollers and fancy
logic...THWPPTTTTT. One fifty cent CMOS chip and a fe bipolar transistor
drivers will do just fine, thank you.

Here's the short version, Jim:

I want to build/install a line of blue "chasing" lights, like the "rabbit"
lights that lead to the arrival end of the runway, in our hallway ceiling.
They will lead people from our over-used "wrong" door (the one that goes
into the pilot's lounge, if you recall) directly to our lobby front desk.
They will be activated by a motion sensor, so they don't run 24/7.

These lights will be installed in the ceiling tiles, one every couple of
feet or so. I've found some perfect blue ones at Rat Shack, 1/2 inch
diameter, 12 volt, that would be simple to push through a 1/2 inch hole
drilled in the ceiling tiles. (Others have suggested LEDs instead.)

The problem in a nutshell: How to sequence them?

BTW, I think it might be more striking to have an inverse rabbit; i.e.
all the LED's are on, but one..You chase the dark one...
