3D printed LED juggling ball powered by an ESP32. Watch a demo on Youtube: https://www.youtube.com/watch?v=KDMFEAo71LQ All code files and detailed instructions are available at https://github.com/scholtzan/juggled *Printing* Inner core - transparent PLA+ with 5% infill Outer shell - transparent TPU with 30% infill *Electronic and required materials* - ESP32
 DEVKIT V1 - This development board has an onboard Bluetooth module, will control the LEDs and collect data from the accelerometer - Lithium 
Battery
 3.7V - The battery will power the ESP32 and all other components - Li-lon Battery
 Charger - This component will ensure that the Lithium battery can be recharged via micro USB Accelerometer - For collecting data on whether the juggling ball has been thrown or caught - 2x RGB LEDs - To make the juggling ball glow - Resistors - 1x 1kΩ - 1x 4.7kΩ - Used to read the battery charge via the ESP32 - Switch - To turn the juggling ball on and off - Capacitor (1 to 100uF) - Required in order to ensure ESP32 gets flashed without having to push any buttons on the microcontroller - Wire - For connecting all the components - Heat Shrink Tubes - For insulating soldered wires - Soldering Iron + Solder - All the components need to be soldered together - Transparent TPU - For printing the outer shell - Soft and flexible material will ensure that components and inner core are protected when juggling balls are dropped - Clear PLA+ - For inner core that will help to keep electronics in place - Hot Glue - For glueing outer shell onto inner core and for fixating electronics
