On 5 December, we carried out a number of tasks. Firstly, we made cardboard prototypes of the boxes that will contain the sensors. These boxes will be sewn onto the bullet-proof vest. We took the necessary measurements to ensure that the boxes would fit the vest and the size of the sensors perfectly. The boxes at the front of the vest will be 4.2 cm wide and 6 cm long. They will be 2cm high and 0.5cm thick.
Similarly, the box containing the arduino board, located at the back of the jacket, will be 3 cm high and 0.5 cm thick. The length will be 12cm and the width 8.5cm.
We've chosen to include a hole on each box so that the wires can come out and link the boxes together.
Finally, we made a prototype of the box.

We also ordered the last sensors we needed, such as the lasers.
