How does it work - show segment

[jonovid]

here is a suggestion for new videos by Dave.
I did like this example of how does a USB keyboard work.  more video like this please!
why not have a How does it Work or What's In A Signal show segment? is in an opportunity to give your top end oscilloscopes a workout.
here is a good example, see this video about USB & computer keyboards
but can also apply to any consumer electronics.

 think of it as an electronic teardown as opposed to the usual electronics hardware teardown.
 
some may not like the probing of industel & military electronics.
maybe too secret squirrel go figure.   but same obsolete hardware should be ok for probing?
