What would you get if you crossed a gigantic Christmas tree ornament with an LED strip and Arduino/IMU control? Perhaps you’d come up with something akin to this colorful “RGB LED Ball” by James Bruton.
The device features eight curved supports along with a central hub assembly, forming a structure for APA102 RGB LED strips. Each of these is linked together via wiring that winds through the central hub making them appear to the Arduino Mega controller as one continuous chain of lights.
Several animations can be selected with a pair of control buttons, and the ball even responds to movement using an MPU6050 IMU onboard. Files for the build are available on GitHub.
