    Predator costume with active 3D head tracking by the plasma cannon

    Hi,

    I chose Teensy 3.5 because of the incredible power of the mc (120MHz!) and a math coprocessor.
    Active head tracking requires a lot of float match to be performed repeatedly and very very quickly to keep the quaternions updated.
    Teensy does the job beatifully and is the central brain of the costume animatronics.

    About the project:
    This is a full-body costume of a Predator with a lot of animatronics, two sound systems, laser sights, etc.
    The full project description is available here.
    The full source code is here.

    I forgot to mention that in the process of developing this, I modified two libraries to make them Teensy-friendly:

    Enjoy!
