You can put a paper ticket in a scrapbook and show it to your grandkids one day and say "See, I was there!" It's pretty hard to put a cellphone into a scrapbook.
One of the current scams starts with the caller saying "Can you hear me?" They're trying to trick you into saying "yes" so they can get a recording of your voice saying this. The recording is then used for various types of fraud. If a stranger calls you asking if you can hear them, either say...
Smart move, Chauncey. Those are called SIT tones (Special Information Tones) for anyone wondering. They are intended to inform the caller (or robodialer) that a line has been disconnected or otherwise modified, and this tricks some systems into automatically removing that number from their...
Ultimately it's primary job is to illuminate a paper ticket that's usually printed on thermal paper, and it's second job is to light the path to the seats. I suspect that a warm white would be slightly better for the tickets. This is easy enough to test using a store receipt, which is usually...
Yeah, the bluer the light, the more Rayleigh scattering you get. I suppose you could drop a yellow filter in front of it to punch through smoke a little better.
Thanks Dave. Yes, the old carbon foam did have a tendency to crumble and make a bit of a mess. Maybe there was a change in it's composition because of this, trading off conductivity for mechanical stability. All of my recent purchases of thru-hole chips come in anti-static plastic tubes so I...
Not a crazy question at all. The conductive material shunts out the static buildup. It's the same reason why you get more static buildup in your hair from a plastic comb than a metal one.
