RS-485 or Ethernet?

Yeah, just a little ambitious me.

Check out our website for info on the show http://www.hackman.co.nz/ (follow the links to Apollo 13 : Mission Control)

We mounted this show last year in Wellington, New Zealand. I made a system of transistor switched LEDs (about 400 leds grouped into 12 chs) and set them inside about 60 consoles that the audience sit at. Response was fantastic, amazing actually, but there was a big call for more interactivity (enter Arduino).

So in July/August this year we have the next seasons, this time with 100+ consoles. Budget/time constraints will dictate a hybrid of the old LED system and about 5-10 Arduinos, but after that it's all on! Future proof is the key... I'm designing everything technical in the show, and do a spot of acting too, so believe it or not, this Arduino system that I'm spec'ing is about 1/10 of my job.

I'm fully expecting to be frustrated, angry and hopefully pleased (hmmm definitely pleased) Luckily I'm not a total beginner with electronics!

Thanks for your advice AB! do you ever leave little //haikus to cheer yourself up when code isn't going so well?
