Building motion capture / mocap suit using 9 Axis Inertial Measurement Units With Raspberry Pi Zero

Mocap Suit Building Part 1
This is an honest try to make a motion capture suit or mocap suit for my RPG video game. In this video I have demonstrated the initial requirement and approach to design and goal of building mocap suit. I am using Adafruit BNO055 and Raspberry Pi Zero 2 W. This is part one of the series, where I just managed to extract the data from the sensor and printed in the console.

Amazing!

[@eatsleepwithme5062]

Do you offer any private mentorship? i am just planning - in case i need urgent support. or do you know where i can get assistance for this elsewhere?

[@forTodaysAdventure]

I did pip3 install adafruit_bno055 successfully, but python still cannot find adafruit-bno055 module

[@forTodaysAdventure]

apparently it was pip3 install adafruit_circuitpython_bno055

[@others-makingofrpgvideogam4262]

Are you running python using python3

[@others-makingofrpgvideogam4262]

Please check your python version
