For work we're doing with the Nat. Park Service, we're in the process
of assembling a prototype data storage package made up entirely of a
series flash cards. The problem for the NPS was how to record for
long periods of time, under variable weather and climates, using
little power, with a system durable and inexpensive enough to do the
job required with greatly reduced budgets. This system allows long
periods (up to a week) of continuous recording stereo data at 16
bit/44.1kHz. while using very little energy to drive the system since
there are no moving parts. There have been many questions over the
past several weeks regarding long periods of recording.
Of course, the problem will be what to do with it once it's stored on
the cards...
