We'll see if my ISP has fixed my delay problem yet (note the original
message took 3 days to get to the list).

I don't have any hard numbers for G force and duration on the bump, but
were talking about a ~2 lbs object being hit hard enough to move it 1/8
inch or so.

As to frequency, one impact will set off a led blink routine lasting 5-10
sec, then the system resets and waits for another. Ignoring any/all impacts
during that time.

It would be best if this could be self contained.
