The signals this coils picked up from the laptop, that sounded a bit like old modem connecting to the internet are really cool. I think I might build one of those myself (just a coil and an opamp, not the tv oscilloscope). Awesome!
i just read your article on Instructables. It looks cool, dangerous and complicated. When you put the coil to your laptop speakers is the music being transmitted into the TV as well, because it makes the music louder?
@TheMightyKinkle Yeah, that's right. The coils in the laptop speakers make a magnetic field that is supposed to drive the speaker, but it is also picked up by the coil that is attached to the oscilloscope if it's close enough.
