The control box is disguised as a spool of rope, haha! Inside it includes:
mini-size Windows XP computer and 15" LCD monitor
64-channel Data Acquisition (DAQ) card - we used a Measurement Computing PCI-slot card. It has 64 analog inputs and about 1M samples/second.
Wiring and electrical interface between the sensing ropes and the DAQ card.
Power distribution to the computer, monitor and speaker
There are 36 blue sensing ropes total. Each has a wire going to a separate sense channel on the DAQ card.
