 +    - 006: This piece has two holes for M4 screws, them had to be made bigger. 
 +    - 019 and 038: The motors did not fit in the brackets because the centering hole was too small, it needed to be filed. 
 +    - 020: This component needed a hole to house a screw, added afterwards the piece was printed. 
 +    - 021 and 045: A thread was made to this component, in order to attach some metric screws. 
 +    - 043: This components was printed twice, with a different geometry, because the first one was as big as did not work in a good way. Also it needed some threaded holes.

-**Conclusion:** The mirror does move, but the precision of the structure is not that high. This might be caused by a slightly crooked threaded rod and some parts not fitting each other perfectly. That might influence the precision of the system, which is however tolerable for the prototype.\\+**Conclusion:** The mirror does move, but the precision of the structure is not that high.

 + 
 +**Correction:** There was a problem with the vertical movement, because the motor was rocking. The problem was the coupling, which had two holes, for the motor and the threaded rod, not well aligned. After making this component again, the movement was performed without any problem.\\ 
 + 
 +=== 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:** The mirror should reposition itself every 1 minute and the sun spot should not move.\\ 
 +** 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.\\

-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).

 + 
 +The Team is proud of what they accomplished, but if the Team had to do it again, the Team would do some things differently. First of all in the beginning there was a lot of indecision about the purpose of the mirror. If the Team had solved this earlier on, the Team would have had more time for the project development. Furthermore the purpose didn’t really need to be decided because the automatic orientation had to be the Team’s main focus. 
 + 
 +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. 
 +The Team also mentioned some risks in the beginning of the report; the Team came in touch with a lot of them. During the building of the prototype, some materials arrived late, some holes were made too big/small, and the Team probably went a little over budget although the price of the 3D-printed parts is unknown. 
 + 
 +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 is proud of what they accomplished, but if the Team had to do it again, the Team would do some things differently.+The Team lowered their environmental impact by choosing renewable resources but also by choosing to send the product unassembled. By sending the product unassembled, less transport will be needed, but also less packaging. The product can also be made solar powered; this was unfortunately not within the budget.

 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.

 **Margot Gutscoven: ** // EPS thought me to work in group with people I barely knew. You should stay positive and give them the benefit of the doubt. Also that in a project you have to think of more then just the obvious technical aspect, you have to think of marketing, project management, the ethics, etc. It also brought me out of my comfort zone of construction and showed me a little bit of programming, which in a way I find unfortunate, because I didn't always feel helpful. Nevertheless, I am glad I joined this program, I definitely made new friends, great memories and learned new things. // **Margot Gutscoven: ** // EPS thought me to work in group with people I barely knew.

-**Raymond Quinn:**+**Raymond Quinn:** //I found the EPS a greatly rewarding experience. The opportunity to enhance my team work, communication and interpersonal skills in an international environment will prove invaluable. EPS also forced me to think about the less technical aspects of engineering project work – Ethics, Sustainability and Marketing – issues that I don’t often thoroughly consider during project work. It was also rewarding to take on board the ideas of others, as often decisions I disagreed about or was unsure about turned out to be good ideas after a group discussion. My only disappointment during an enjoyable semester was that I found it difficult to apply my knowledge of power engineering to the project but this allowed me to take on other unfamiliar roles and also to learn more about electronics and computer science.//
