Here's a challenge. I don't know where to start.

I was a little vague.

Say I have a long table with three stations, each has a 10w power adapter coming from it. Red light on when power is off, green light on when power is on, yellow light on when 1/2 time remains.

The "button" is really a computer input. Could I send a "yes" to station 1 and have it turn on while 2 and 3 remain. Or even better, have the computer handle the timing.

The lights simply indicate the availability of current, "in-use." Is there a way to get a "server" to send the "on" signal to stations independently of each other.
