Spinningball (fablab) and Stuff That You Need

We got a school project to make something. I wanted to make a ball that was spinning with light inside. I made a drawing in tinkercad. I used a 3d printer to print it out.

Stuff that you need:

Wood for the lasercutter. (and a lasercutter)
A 3D printer.

A motor ( I used a stepper motor so you need an arduino too and a special chip for it.)

And some wires.

This is how I made the electronic circuit. I used a steppermotor (this is what I used for my steppermotor https://www.instructables.com/id/BYJ48-Stepper-Moto...). You can use every motor you like, if it's strong enough.

The circuit I got it from https://www.instructables.com/id/BYJ48-Stepper-Moto... so check this page.
And the code I got it from him too.

Here is the code: (I uploaded the file too here it's called met_led.ino but in that one you can use pin 7 for a LED.)

} void loop() { while(steps_left>0){ currentMillis = micros(); if(currentMillis-last_time>=1000){ stepper(1); time=time+micros()-last_time; last_time=micros(); steps_left--; } } Serial.println(time); Serial.println("Wait...!"); delay(2000); Direction=!Direction; steps_left=4095; }

void stepper(int xw){ for (int x=0;x7){Steps=0;} if(Steps<0){Steps=7; } }

I just 3D printed a small ball with a flat bottom.

I used a lasercutter to cut out the case (used this site http://www.makercase.com). It was easy to use you can make the case how you liked, but pat a hole in the top and have enough space inside. I have als a hole on the side for the adapter in my arduino. I didn't glued one side so I can put the hardware in it and change it later. I uploaded a picture how it should look like and one with a hole the holes are 12.7 mm in diameter. I prefer the one with holes so you don't have to make the holes by yourself.

Put everything inside the motor in the top hol. You can change it how you like it. You can put lights in it you don't have to use a ball as top you can use a plate to put everything on it what you want. I have some lights inside it so I can see when it's on.

EDIT: I added a cardboard plate instead of glueing the ball on the motor, so I can switch between objects.
