I have a problem at work of people starting to talk to me when I'm on the phone (computer based IP phone) or listening to music.
I thought I could just use a splitter from the headphone jack of my computer, and use some kinds of IC realy to power a LED that I could mount to my monitor, so people can see if I'm on the phone before they start talking at me.
Ideally it could or should be a latching relay that I could reset so the light doesn't go out if there is no quite spot in the music.
I am familiar with 24V & 110V industrial controls, but have really no experience with this tiny voltage / current stuff.
My questions are, would this even be possible off of a headphones jack?
What IC relay would do the job?
