[posted] 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.

Thanks for the modded PCA9685 lib! Going to try it later this week with a Teensy 3.2. Did you have to use the resistors on the RX line between the PCA and the Teensy?
