whats the best way of lighting this rotating sign?
UPDATE 2007-02-14
UPDATE:
The customer wants now, the red fields are moving like this:
Hi,
every help very appreciated on this:
I need to turn-on the red fields of the roulette gradually:
Step 1: red 5 on
Step 2: red 16 on
Step 3: red 1 on
etc…
Step 9: red 3 on
Step 10: all red fields off
and again
Step 1: red 5 on
etc…
Step 10: all red fields offIt should symbolize the movement of the roulette, so the interval between turning-on the fields should be shortly. It is a double-sided, 14 CM (app 5,5") deep sign, so I think, LED is not really a choice.
The light source in the red fields is a 15 CM (app 6") neon in every red field.
What is the best way to achieve the wanted effect?
Thank you all.

For starters, the basic electronic circuit would be based on a LED chaser. If you want to get fancy, you could tweak it to randomly fire 1 out of (say) each group of three.
I don’t know how convenient electronics hobby shops are for you, but they would have a LED chaser, and perhaps they would have circuit diagram for roulette wheel project, like you are asking about.
Actually, I just did a search for keywords of "circuit diagram roulette" and found a number of references. Here’s the first one:

Seems like there is some info missing here. So the sign is 14cm deep – what is the diameter of the entire sign? Do the light have to chase in opposite directions – ie correctly on each side of the sign?
You’re better off using either an neon chaser system (if you insist on neon), or use Red LEDs controlled by either a DMX controller, or a standalone LED control of some sort.

Thank you guys!
For this job we have to stay on neon, since the tubes are already produced.
Since the sign is double-sided, the graphical part is color-identical on both sides (red/red). I have chosen a neon, because I can illuminate both sides whit one neon.
I have googled for neon chaser and found this:

I’ve seen those chaser’s used in the past, and it should do the trick for you. Even though you may have to have more than one ‘number’ illuminated at a time… it will still give you a convincing enough chasing red effect.

The job is done.
The movie is to see on members portfolio.
