My turn to ask for suggestions.
My daughter-in-law is a costume designer for a children's performance academy. Today she asked me for suggestions of how to add lighting effects to 60 costumes for a presentation in January 2014.
Her initial idea is to synchronise the individual leds to either the music and/or the performer's movements. I like the WS2812 RGB devices and these could be wired into the costumes with conductive thread, but the means of activating them all at the same time to the music begs the question... what comms to use for 60 performers on a single stage at the same time. There will be lots of organic obstructions, so I am open to suggestions.
I envisage using one of these 18560-based power packs.
