| + | === 7.11.5 Sun Tracking test === | ||
| + | After the corrections of vertical and horizontal movements the sun tracking mechanism was tested.\\ | ||
| + | ** Method:** The mirror was placed near the window and the focus point was adjusted. Then the mirrors behaviour was observed for over 1 hour.\\ | ||
| + | **Expected behaviour: | ||
| + | ** Result:** The mirror was repositioning correctly. the sun spot was not moving. Below is the timelaps video of the whole test and the photos which were taken every 5 min for 1 hour.\\ | ||

| * At the beginning, the construction process was performed slowly. The main reason was because the lack of experience regarding using the most of the tools that the workshop had to work with. For instance, the technicians helped the team in some operations, such the welding or the machining process. For this reason, the team is aware that some of the components could be manufactured better. Even so, the team is proud of the final result, even if it is just a prototype. | * At the beginning, the construction process was performed slowly.

| - | The goal of this project was to develop a Self-Oriented Solar Mirror (SOSM). The mirror must track the movement of the Sun and reflect the sunlight onto a predefined area. The creation of the sun tracking system was one of the main challenges for the team. The SOSM had to detect the Sun by itself with the aid of software that knows the path of the Sun. | + | The goal of this project was to develop a Self-Oriented Solar Mirror (SOSM).

| - | First of all in the beginning | + | At the end the Team lacked a little bit of time, the prototype was not finished before the report had to be handed in and so the Team couldn’t do a 24 hour test. For the tests and results it would have been better to place the mirror with the software and see if it starts when the sun rises and moves during the day the way it suppose to and stops when the sun goes down. |
| - | - Indecision in the early phase | + | The Team also mentioned some risks in the beginning |
| - | - No 24h test | + | |
| + | On the other hand, the Team can certainly say that they achieved many things. Although the team members didn’t know each other, the team members managed the work of 5 people. Every team member did their part and if there was a disagreement, the Team managed to solve them quickly. In the beginning of the project the Team made some rules, one of them was that every decision needs a majority of four to pass, and everyone kept that promise. | ||
| + | |||
| + | The Team lowered their environmental impact by choosing renewable resources but also by choosing to send the product unassembled. By sending the product unassembled, | ||
| + | |||
| + | The Team designed a prototype and a control system; the Team built a moving structure, assembled the electrical components, developed the software and eventually finished the prototype. Although the mirror doesn’t move as smoothly as the Team had wanted to, the mirror moves the right way and thus works the way it should. | ||

| Working within the time and budget constraints of the EPS meant that the team focused on creating a proof-of-concept SOSM for domestic use while considering the features that the final commercial SOSM would have. One such feature would be the ability for the user to update the mirror’s location using buttons on the device rather than having the device pre-set to one location only, without the possibility of editing the location easily. The team also wanted the device to be more sustainable – to be powered by a battery charged by a small solar cell instead of being powered by the mains supply. The commercial product would also have a liquid crystal display (LCD) to provide the user with information on the status of the mirror. The final product would also possibly have a larger mirror surface made from glass. | Working within the time and budget constraints of the EPS meant that the team focused on creating a proof-of-concept SOSM for domestic use while considering the features that the final commercial SOSM would have.
