Hi there!
I am working on an entertainment system designed for a concert, where a lot of balls will be lit by color LCDs.. This devices should react at the same time and on command to change color. This devices will be dispersed in the audience of the concert and should be controlled by a master console that will issue the commands to change colors in sync...
The question is with regards the communications from the master station or console to the devices... We are doing around 300 balls.. So we are looking for a way to talk to them wirelessly but with low cost so that if we loose some, it will nut hurt the pocket too much...
Any suggestions welcomed!!!... IR? RF? ETC! All welcomed!
