Use laser cutting to cut 4mm plywood as the base.
Size: 24(W)*24(L)*11.3(H)cm
Use rod nut to fix the threaded rod with the base.
Use rod nut to fix the threaded rod with the
3D-printing part.
This part is to connect the threaded rod and the acrylic ball.
Six holes are used to let the wires of LEDs, servo moter and sensors passed through since the Arduino is set at the base part.
Acrylic boards are all covered with dichroic filter to refract white light into different colors.
Use plywood to print supports to fix LED and dichroic acrylic board with the acrylic ball.
For further revision, supports with different longer length will be printed to get better effect.
Lights with different blinking patterns and project to the dichroic boards.
Problems now: Some of the LEDs cannot be lighted up, will check the wire connection and the voltage.
Fix the LED with servo motor at the top of the acrylic ball.
