Final Project – Motion Sensor Solar Powered Desk Lamp

Question 1:

For this final project, I made a solar powered motion sensor desk lamp controlled by Arduino. The lamp is made by cutting a block of wood into three pieces. Two of the longer blocks are for the stand which is connected to the other block for the head with a screw, winged bolt, and washer to make the head adjustable. I faced a lot of challenges in the project which are to create the solar panel, connecting it to the Arduino, programming the Arduino and doing the woodworking as I have never had any experience whatsoever. I am really proud of building the solar panel with the help of Brandon. Never I would have thought that I would literally build the solar panel circuit myself (thought of buying it at first), but after much experiments, it was done!


Question 2:

First, my learning goal was to get more of hands-on experience on building things. I come from Indonesia and woodworking was not something that was really taught to students however, crafting was something that has always intrigued me since childhood. From that, I hoped to gain the basic skills in woodworking and using power tools to create new products from materials such as wood. After doing the project, I have gained the basics in modeling materials such as cutting the wood using an electric saw and drilling using the heavy machine with supervision from the representatives in charge of safety.


The next learning goal I had in this project was to do something more on the engineering side and gain more technical skills. Although I initially thought that I am a maker by heart, this ideology does not really translate using the technical skills that I possess and have to apply to the project. So, by the end of the project, I hope to gain knowledge about circuits and power conversion. After doing the project, although not much, I did gain this knowledge such as if you are using a parallel circuit, you will get an even voltage distribution and more current (yeah, this is what worked for my project).

This learning goal also aided me in another personal goal, which is to get closer to the people in the FabLab. Earlier in the semester, I was so mesmerized with what the members of the lab are doing and really wanted to get involved. However, as the semester, I did not have that much time to come to the lab aside from class hours. So, from this project, I vowed to at least to get closer with someone (aside from my awesome instructor Emilie). After doing the project, I did get closer to one person, Brandon. Brandon was really helpful during the entire project. He helped taught me how to create the solar panel power source and how to connect them to the Arduino. Moreover, he also helped me a lot with the coding part to program the motion sensor and the lights.


All in all, I think that my project was a huge success in my own metrics. Never would I expect, an accounting student like me to create something that so far away from the education discipline I have been going through for the past 4 years and created something that does not require me to make balance sheets or income statements. Although it is successful according to me, there is definitely room for improvements. First, I should have made the cable to the solar panel longer so that it can be moved more freely. The lamp can be plugged to a portable power source, hence it could be a portable lamp. In regards to that, I would think that making the body of the lamp and the Arduino box waterproof would definitely take my project to the next level. I really think that my project is important as it is definitely a step into the future. I think climate change is destroying our world and finding an alternative power source is a step to a better world. The motion sensor is there to limit the power usage as the lamp will turn off if you do not need it anymore and the lamp is entirely solar powered.


Question 3:

This class has taught me a lot in regard to technical skills as well as self-development skills. One thing that I learned from this class is that it is okay to make mistakes. As a business major, we were taught that it is imperative to not make mistakes as it would hinder the efficiency of the whole business process. Although not making mistakes is important, mistakes are valuable experiences that remind us that if one way does not work, you need to find an alternative to it. From mistakes, I learned that although a solution might logical sense, it might not work the same when applied due to other factors. This brings me to another lesson I learned through the whole experience, which is to be resilient. I am not the most efficient and smartest person when it comes to making the projects given in the class. It took more time for me in doing and also designing the projects. However, the class taught me that I have to struggle and stay resilient in finishing the tasks, which actually bore wonderful fruits. I can say that I am proud of the creations I made in the class (although some were really terrible, I know). One thing I found comfortable doing is actually using the Arduino. I was always inclined to this part of the class for its limitless ability. At first, it was hard, but after doing 4 projects with it (2 Arduino projects, 1 iteration project, and final project), I came to enjoy doing it and might I say be decent at it. 


Question 4:

Before taking this class, I thought that a maker is someone who makes something from nothing to something. However, this class has taught me that there is no one single definition for a maker as everyone has different and unique making processes. My definition of a maker is someone using tools to add value to something and tells stories using their creations (kinda borrowed the quote from Adam Savage[1]). By that definition, I am definitely a maker. Every learning experience I obtained from the class had been hands-on and meaningful for me in different ways. I definitely think that the quote means more to me now than it had at the beginning of the semester. With the skills, I gained and the understanding of the lessons’ objectives, I can confidently say that the class had given me a more holistic learning approach to making as it encompasses education disciplines as well as backgrounds. The hands-on experience helped me understand the matter at hand as I do not need to visualize the concept, as I can just try it out with the devices that are available in the lab.
