1. A system for digitally recording the motion of an instrument including:

  • a power source;

    at least two hollow tubes made of electricially conductive material coupled to said power source through first connection, said at least two hollow tubes including a viscous material in the interior contacting said electrically conductive material, wherein when said at least one of said at least hollow tubes moves in an axial or rotational direction, said viscous material contacting said electrical conductive material;

    a power sink coupled with said at least two electrically conductive hollow tubes through a second connection.
