Rubisyncs embed timescales in the physical world.
These timescales and corresponding magnetic field measurements can be synchronized to create visualizations.
I am currently using PNI's SpacePoint Fusion for 9-DOM magnetic field, acceleration and rotation measurements.
Previously, I had tried to embed the timestamps in the data stream. This was not a simple solution.
Embedding a timestamp in the physical world can easily be done using a GPS module with a 1 PPS (Pulse Per Second) output and a coil of wire. It may also be done with an autonomous atomic timescale generator.
