This is my version for smart juggling balls. The idea is to create an open source platform which can be used (besides juggling) as an educational platform to teach physics using an interactive and fun way. The platform contains a 6 dof or a 9 dof sensor (Mpu 6050 or Mpu 9150) , micro controller, transmitter (NRF24L01) and some LED`s
Currently I have a working version of the balls, which can be used for juggling:
The files I share include PCB Circuit manufacture files (Gerber) STL models for the casing, BOM with links, assembling instruction, and codes (currently Test code). all are available at: https://github.com/arkadiraf/Juggling_Balls_Public
It is possible to assemble the juggling balls using a prototype PCB such as: https://www.sparkfun.com/products/8810 my first iterations were based on the same prototype board and later the PCB was design based on the physical dimensions of the board.
As a first stage towards educational platform i am planning to improve the PCB design so it will be more user friendly and use it as a platform to teach soldering.
Later the kit can be used to teach coding and communication.
In parallel i am planing to start working on a lecture content for physics class.
