  And are you reading that visually in Morse code? I would have thought a different/more optimized flashing pattern that required a smartphone to read would be faster, especially if we're talking IPv6 addresses, but that's just me.
  • Arnavion 7y ago
    Yes. I made it flash 100ms-on-900ms-off for a ZERO, and 500ms-on-500ms-off for a ONE. There's a 1000ms-on-1000ms-off flash at the beginning to indicate the start point. And it's IPv4, so there's only 32 bits. So it's slow enough to read out and type out into a text editor, then convert the typeout to its IP, but not slow enough that it's a bother.

  That was the part that really jumped out at me as well. I've had the same problem before and this is a genius solution.

    ditto – is the script available somewhere? I typically end up just nmapping :-/

        =D thanks!

  I feel compelled to point out that FreeBSD manual page for the led driver has this example: /usr/bin/morse -l "Soekris rocks" > /dev/led/error Guess what it does :-)
