    Something to consider. Sort of like the "build it and they will come" idea. Design a clever (hopefully useful) "thing" for the IoT, someone will take the challenge to hack it, and - an engineer will figure out how to keep the hacker out. Until another hack finds another hole - and the process continues. . .

    Ironic that Morse's 'dots and dashes' of yesteryear have been supplanted by '0 and 1's' of computer binary code today. Using not two, but three stooges to find humor in the duality of a binary world...slapstick indeed!

    #12 Lisa - Yes, I turned my phone horizontal/sideways. I think my phone (Samsung Galaxy S4) is defaulted to "auto rotate" and it does fine. If the phone is held vertically, you lose a lot of screen space. Take a look at your camera settings and enable "auto rotate" and then give it a try.

    #7 It´s a fun experiment and definitely cool that you can build gadgets like that.
    Wayne Yoshida
    24/10/2016 #7 Wayne Yoshida
    #6 Excellent question! The short answer is - no, it does not distinguish between - lightning and other interference since they are all very similar. But, I can verify this is detecting the lightning because other official detectors are finding it at the same time.

    I actually think that's pretty cool Wayne. But I admire techie minds that can build things like that. When my youngest brother was in his early teens he had a stereo that stayed on a shelf above his bed. (this was pre-remote controls ) He liked to listen to music when he went to be but hated having to get up and reach up to turn off the stereo. So, he took the darn thing apart, found the gizmo that controlled power going to the stereo, rewired it to a toggle switch which he mounted to wall just above his head. (Don't you love my technical jargon :-)) Not bad for a 13 year-old. Now he's a desktop engineer. Go figure.

    #1 Thanks for watching and commenting, Aurorasa. I was thinking about adding more to the text, but wanted to make sure I captured the yellow light flashing and the meter needle moving. The static noise is something I want to fix, I want a more "pleasant" sound coming out of this thing when lightning is detected. Maybe like a chime or bell.

    During demonstrations, I use a BBQ striker to simulate lightning.

    Here is more information on this gadget. It was originally meant to be a high-tech decoration in my living room.

    That´s a great example of a "great post" comment. How do you know it´s working? I hear a static sound ... and I see the light blinking. Watched the video, thought it´s cool but I guess you have to have some knowledge on the topic to fully understand how cool it is.
