Hello
I have been asked to find out if it would be possible to power a relay via the power a 3.5mm headphone jack on a pc.
Basically the current phone system in the office plays a tone every time there is a queue of calls on hold. Its been decided that the noise is inappropriate and they would rather have a signal light.
So what I had imagined was wiring up the lights and in between the lights and the mains power supply placing a relay. This relay would need to be activated by the AC power output from the 3.5mm head phone jack on the pc when the sound is played and remian closed for a designated length of time. I can modify the sound file the system plays to a continuous tone to produce as much constant power out as possible.
I'm not sure if this is even possible, but does anyone knows of a realy like this?
Or if anyone has any better ideas?
Thanks in advance for any help you can give me!
