Hi! I am tinkering about a project where i need to switch a lot of lightbulbs on and of. So i searched and found some approaches. A project some of you might already know is Blinkenlights: http://www.youtube.com/watch?v=nFacSJBCql0 Here is some interesting information provided about the setup of blinkenlights http://www.retrocmp.com/projects/blinkenbone I was always searching for a way to do something similar myself.
Is there a known way to switch "a lot of" (lets say 128) 230V AC lightbulbs? Relayinterfaces for pc offer mostly only 8 ports. Didn't i find the right devices? Or searched the wrong term? Another way some people try are houseautomation devices (i don't know anything about these).
Could you imagine other ways to do this? Do you know interfaces which use lets say 12v (for small lightbulbs) and handle this without relays?
Perhaps you have an idea! Thanks a lot!!!
