Data communication over the power grid.
Anons I came to this idea because my alarm clock refused to work today.
It just shows 7:L7 which IMO means TILT.
Independently of this incident I asked me the question:
What if data is modulated on the main power grid where
'some' devices listen to? Think internet over powerline for your
home. I dont think that my alarm clock does somethink like this
but imagine modern refrigerators, funky Google/Amazon/… home devices
could receive data without Internet access.
And even if someone monitors their activity this channel would be
most likely not recognized.
I have no Oscilloscope to get any further. Just wanted to share this
idea. And I think Its an interesting one - anyway WGA!
