We researched on which constellations we wanted to put onto our t-shirt, and then mapped them out with a tailoring chalk on the shirt. We then inserted the fiber optics into the shirt at where the star positions should be. Since the fiber optics fall out of the shirt too easily, we had to tape them down temporarily. We grouped the fiber optics together according to which constellation they belong to, and then sew the group onto the shirt to keep them in place. So we had to bring an actual large sewing machine to school to work on the shirt. Sewing took a long time because we were all unfamiliar to the sewing machine and it took time get accustomed to the machine.

We also worked on the coding part of the Arduino in order for the LEDs to blink/light up from the data sent by the sensors. We spent a long time finding a place to put the accelerometer that would get the best readings from the body movements. We tried the arm, the inside of the arm, the tail of the t-shirt, the upper part of the back and on the side of the shirt. We concluded that the best spot to put the accelerometer was on the lower back of the shirt.
