Now the thing is, not wishing to be cynical, that could be almost anything.
it is a bit like what happens when you try to drop a stylus on a record
start and it skips off.

Then again, putting a sensor on anything you drop from a height would

The sound file they were playing as nauseam on the radio while it was
still a news story was the output of the magnetometer modulating an AF
signal. The "Singing Comet", they called it.
