1. A method for determining a rotational orientation of an object, the method comprising:

  • providing a plurality of concentric shells, wherein an electrically conductive shell, connected to one or more power cells, is disposed between an outer electrically non-conductive shell and an inner electrically non-conductive shell and one or more electrically non-conductive spacers separate the inner electrically non-conductive shell from the electrically conductive shell, creating a gap;

    attaching a plurality of electrically conductive nodes to an outer wall of the inner electrically non-conductive shell;

    disposing an electrically conductive fluid in the gap;

    conducting an electrical charge between the electrically conductive shell and a portion of the plurality of electrically conductive nodes in contact with the electrically conductive fluid;

    transmitting electrical signals individually conducted by the portion of the plurality of electrically conductive nodes in contact with the electrically conductive fluid, wherein the electrical signals are processed by one or more microcontrollers;

    generating, using the one or more microcontrollers, an indicator of a rotational orientation of an object based on the portion of the plurality of electrically conductive nodes; and

    outputting the indicator of the rotational orientation of the object.
