I have seen many projects like this for raspberry pi.
I was wondering:
a notebook has a lot of gpio pins driven by PCH or other devices.
Most of them are very common.
Would it be possible to modulate any GPIO (like one connected to a led or something not so vital) to produce a very low intensity signal inside the notebook?
Think of it as a sort of NFC...
