Science Engineering project blog post #4-Reflect and Share

Images and videos of the final project:

I have now attached everything and essentially completed my final step in my design, now I just need to tweak and make adjustments to the angle of rotation and the speed at which it is spinning, all to better suit the purpose and design of this project. The video is attached here.

Here is the grande final version of the project; this video was filmed in school and demonstrated how the mixer worked. Mr. Hussack gave a fantastic idea to employ food color to show the “mix,” as can be seen in the video here. It was honestly both shocking and extraordinary to see it work so amazingly!

Here is the link to the one drive folder containing the design process of this product and all the videos shared.

The science behind all this that allows the project to work is relatively straightforward and relates to the transfer & movement of energy. As the motor is electrical and needs electricity to function, the principal and only energy source are the six AA batteries that power up the motor, which then spins the wooden platform and consequently spin and mix the cup. The flow of electricity travels around in a loop or a circuit that maintains the balance of the negative and positive charges; it is constructed so that the negatives and positives do not intersect and therefore do not create a short circuit. The switch acts as the circuit “gate”; it allows electricity to flow through once opened and ceases electricity flow once closed; this is greatly necessary to control the motion of the motor, or else the motor will constantly be spinning. Furthermore, chemical potential energy is stored within batteries, and electro-mechanical devices, such as the rotation motor, convert the energy transferred from the batteries into motion. When the motor is spinning, electrical energy is constantly converted to rotational motion, which then outputs to the wooden platform, turning the cup.

In my opinion, the most prosperous area in this project was designing the product, applying feedback, and making changes along the way, essentially the “create and improve” process. It is undoubtedly normal to make mistakes and face challenges during the process of designing; however, I believe it is vital that we take the time to reflect upon our work and, most importantly, ask & take in feedback from others, ultimately applying those and make corresponding changes. When I encountered challenges, I reached for help from my peers and adults, received their feedback, and used their suggestions for my own project. This, I believe, was a strength of mine as I was able to significantly improve my work and reflect upon my error,; correct them, and enhance them. Moreover, I successfully designed the motor placement and its connection with the wooden platform. I specifically made the platform attached at an 80-degree angle so that the cup, when spun, will create a whirlpool effect that, to a large extent, helps the “mix” of the liquid. This unique detailed design turned out to be very successful and efficient.

An area of improvement is definitely the aesthetics of the project; although it functions well, it simply looks too pale and “ugly.” I always plan to decorate the foam box with colors and papers once I complete the electrical and “essential” parts. However, due to time constraints, I did not have the opportunity to do so. Again, this is my personal mistake as I should not have spent the first three classes working on a project that did not function, but instead, I should plan my time and project wisely and more productively in the future.

This project primarily aims to help people who require a machine to automatically mix/shake a liquid (most cases a drink) and generally people who are causally in the kitchen, making food, drinks, etc. The project’s theme is focused on relaxation and enjoyment and comes in handy by saving time and unnecessary actions, as the machine will do it for you. Not only does this project target family-based consumers, but also possibly industrial clients, who require large amounts of work without the need for human power. This project clearly saves people’s valuable time and efficiently produces, with quality, the drink or liquid substance they require. Additionally, apart from the styrofoam box that was supposed to be wooden, the materials needed to create this project are environmentally friendly and sustainable, providing a valuable machine to society while remaining eco-friendly. This makes a general impact on the environment as more consumers and clients are willing to use this design. We live in a world in desperate need of environmental protection and the sustainability of our earth; eco-friendly products will be higher in terms of demand in the market, followed by a possible higher output price.

 

Science Engineering project blog post #3-Create and Improve

 

Design class #1 This is a picture of my collection of *starting* materials, including the AAx6 battery pack, electrical rotation motor, suction cups (always kept spares), servo tester, a level switch for testing, and an Arduino in case I needed to code & program. Note that the rotation motor here is black and differed from the blue one; this was the one I began to use first but was later switched to the blue one (see picture below) due to its heavyweight and size.

Design class #1 This is when I collected all the materials and started my first test run of the motor, with the rotation motor (black in the picture but was later changed to blue) connected to the battery with alligator clips. The trial run with the black motor was reasonably successful and the motor functions well. In the meantime, Mr. Costa, a design assistant in the engineering space,  suggested I use a much smaller rotation motor (as can be seen on the left of the servo tester); despite its size, it was particularly potent-even more powerful than the previous black one! Applying the feedback from Mr. Costa, I then changed from my original motor to the blue one; it turned out to be exceptionally useful and provided immense strength. Thanks, Mr. Costa! (The blue motor was tested outside of this picture. Unfortunately, the photo of the blue motor being wired to the system was not taken, but it is essentially the same circuit, only replacing the blue motor with the black.

Design class #2 Here is the “light switcher” I have made from a 12cm long wooden stick and the hard-plastic motor connector piece attached to the front +/- 2cm of the tip by hot glue. This will be attached to the blue rotation motor by placing the connector piece onto the motor attachment place. I have done multiple tests for secureness, and I am definite that the wooden switch will stay in place during the spinning motion.

Here is a demonstration video to observe the motor turn with the wooden switch attached. I have also shown how the servo tester can control the speed at which the motor is turning and its spinning direction. I apologize for the video exceeding the upload file limit on blogs and have shared it in a one-drive folder instead.

See the source image

During design class #3, it was heartbreaking and unfortunate to encounter serious difficulties and errors in my project. It turns out that despite the abundance of power I believed the blue motor had, the power at which the motor is spinning the wooden switcher was, in reality, way too low to even turn the light on. As a result, it would simply hit the surface of the light switch at a fast speed; however, there is not enough force to “click” the switch. This was generally my mistake, and I definitely should have considered this more in-depth into this particular aspect before I did the project. This is an excellent lesson to learn and will be nevertheless reflected upon, and of course, taken into consideration for awareness and changes for future projects.

(This was done outside of class) Moving on from the first idea that was unfortunately unsuccessful, I have made the decision to develop a project based on the previously mentioned idea “electric cup mixer & shaker.” I included a materials list in the picture above. As you can see, I wanted to utilize as many as possible resources that I had already collected in my first idea. That way, it saves me valuable time as I can reuse these same resources. Given its name, my new project was essentially a cup mixer that targeted and aimed to help people making drinks who are in a kitchen area. The machine will be operated under electricity, more powered explicitly by a six AA battery pack connected to a 360-degree rotation motor. The entire project will be set on a 20cm long, 15cm wide, and 15 cm tall foam box, with the motor hidden and inside the box leaving only the wooden cup-holder platform on top, and of course, the switch to control the flow of electricity. I have specifically designed the wooden cup-holder platform to be 8cm by 8cm. Therefore, the 5.5cm popsicle stick panels will *securely* hold the majority of all cups, bottles, and can types. -Every bottle/cup I have seen and tested so far fits perfectly except those Camelbak wide ones. The mixer project can be controlled and used very easily; all the user/audience has to do is cautiously place the cup into the secure panels on the wooden platform and simply turn on the switch. The cup should “slide in” and secure on itself; I have purposely designed an elevated angle for the ease of the user and to prevent errors with the cup sliding out.

One concern I had for this new project was the balance and weight distribution of the base. The quick rotations of the cup when it is “mixing” might cause the entire foam box to flip over or become unstable to the ground. A solution to this would be to increase the weight of the platform and the amount of liquid there is inside of the cup, setting a minimum weight (volume) for the mixer project to work efficiently. This number will be around 40-50 ML as the minimum volume of the liquid in the cup.

I plan to finish my second project by March 7th. A new timeline is as follows:

Design class #4 Match 3rd, work on cup mixer project, and ask for feedback from teachers and design assistants

Design class #5 March 7th, finish up the project and finalize it, must apply the feedback given and make changes

The techniques I will need to learn in my mixer project remain the same; learning the fundamentals of electricity as well as circuits & wiring.

 

Design class #4

This is my sketch of the cup platform. It was then marked on a 1cm thin wood and lasercutted in the fab lab.

Here is the 360-degree rotation motor being tested; it is the yellow rectangular object below the yellow plastic wheel. I used the wheel at first, but it was suggested to me by my table partners and design assistants. My original plan (see picture 4) was to directly attach the cup-holder platform to the motor; however, when it was attached, it caused too many contacts with the foam surface and produced way too much friction for it to run at an appropriate speed. Connecting the wheel allowed space between the foam and the wooden surface and worked much more efficiently. The feedback was instrumental and beneficial in my process of designing.

Here is the 20x15x15 foam box. The inside was slightly different from the planned sketch but did not affect my project in any way. When I first designed the project, I was being extraordinarily foolish and absolutely forgot about the thickness of the foam-upper surface and that the motor’s pivoted axle would not even reach up to the surface, it can be pictured as a turtle trying to extend its head out of its shell but gets stuck midway. From another discussion with the design assistant, I was given feedback and advised to cut the styrofoam so that the motor can extend its “turtle-head out.”  As can be seen in the right-side picture above, I marked the area based on the dimensions of the motor and “dug” out styrofoam, making space for the motor to perfectly fit. This eliminated the error in my plan and was practical, realistic and straight to the point.

 

Design day #5

*Note-The plastic wheel is hot glued to the wooden platform

I originally planned for five popsicle sticks for secureness; however, during my process of making, I realized that an extra would be completely redundant and unnecessary. As I have tested, four wooden panels work much better than five and secure the cup efficiently. Along the process of designing, I also learned the technique of hot gluing. Of course, I have hot glued before, but this time, it was to a much greater extent; I had more practice with the glue gun and was able to better control and use the glue gun effectivity towards the project. In the beginning, I remember constantly overusing/producing glue and having to redo my work. Still, as I obtained more and more practice, I learned the necessary skills of hot gluing and applied that to my project.

Here is when I combined the two components together, not by hot-gluing but by using the “click” mechanism of the wheel to the motor. The motor has a concave indentation that perfectly fits the “ridge” tip of the wheel, making a “crack” sound and locks in, like putting together lego pieces. Note that the switch has not been attached yet and the project still remains on a motor-testing basis. The mixer & platform did spin in the way as planned, and worked very well to my surprise.

Here is an overview of my prototype, it is still in the testing process that’s why I used dual AA batteries instead of six.

 

Weekends non-school workday:

Here is the bottom view of the product, as you can see the switch is in place and connected, I have also made holes in the foam to pass through wires and tape to secure the wires as well. The battery is not attached in the picture but is in this demonstration.

Science Engineering Project Blog Post #2- Develop and Plan

Sketches of my ideas, with measurements, materials, 

Techniques I will need to master:

Learning the fundamental knowledge of electricity is vital in my project, as well as learning how to operate with circuits and how to possibly “solder.” I will learn this by browsing the web for information and asking my teachers for help, learning the necessary techniques I require through practice and guidance. I already took a circuit & coding course last year therefore I already have the basics, however, in order to complete my project I need to go more depth with electricity and the techniques that are on a more advanced level.

Plan & Timeline:

Feb 21st: Finishing blog post #1, starting blog post #2 with sketches and specific models for the project.

Feb 23rd: Design lab workday #1, check for the final decision, approval, and begin working based on prototypes by collecting/bringing the materials needed. Document the process by taking pictures and videos.

Feb 25th: Design lab workday #2, continue drafting and making the prototypes for the project, documenting the process along the way.

Mar 1st: Design lab workday #3, continue finalizing the prototypes, and document the process.

Mar 3rd: Design lab workday #4, finishing prototypes for feedback and reviews. Collecting the feedback from teachers and peers for improvement and changes, documenting the changes within the process.

Mar 7th: Design lab workday#5 (last day in design lab), working on the final product, finalizing the product, and producing the best possible work. Apply all the feedback given and make adequate changes to the final product, secure all wiring and circuits permanently and be ready to present the project in the next class.

 

 

Independent Reading Reflection #3

-Recently, I have read a total of two and a half (2 1/2)  novels for independent reading; Stephen Hawking’s Brief Answers to the Big questions during the first semester, The Great Gatsby during Christmas break, and finally the latest Klara and the Sun, by Kazuo Ishiguro. To be honest, although I just started reading “Klara and the Sun,” this book is absolutely unique in terms of plot & theme and is definitely, to my suggestion, #1 number one among the other two books. Nevertheless, all three books are action-packed and are very amusing to read; it’s truly worth the time reading these fantastic books and novels.

-I am currently reading Kazuo Ishiguro’s award-winning novel Klara and the Sun, about five chapters in. Klara and the Sun is set in a near-future society where technology, specifically Artificial intelligence (AI) has dramatically advanced. The story is told from the perspective of Klara, who is an “AF” (Artificial Friend) commonly “hired” by families in the future for assistance and help; Josie is a sick young girl who Klara helps in this novel. The text is very engaging due to Ishiguro’s use of multiple writing techniques and literary techniques, such as lucid structure, metaphors, diction, plot, characterization, description, etc. Ishiguro’s language in the novel is unambiguous and “to-the-point” and portrays characters with various descriptions both internally and externally. This allows me and readers to easily understand Klara and such feelings. The fact that AI already operates and “serves” on such a significant scale already shocks me; therefore, I do not have a particular assumption for the upcoming chapters. I only hope Klara is safe and avoids as much danger as possible, considering a world full of AI can be both good and bad at the same time.

-It was an exceptionally difficult decision to choose a specific book for my literary essay; however, I have made up my mind to choose F. Scott Fitzgerald’s The Great Gatsby, as of now. The novel generally illustrates the American society & culture and the theme of the American Dream. It includes many literary techniques suitable for an academic analytical essay, such as metaphors, similes, allusions, repetitions, direct & indirect personification, setting, and many many more. The techniques are employed on a great variety of focuses, including characters, setting-environment, dialogue, culture and history, and even objects-materials/colors to help present the theme.

 

Science Engineering Project Blog Post #1- Define and Inquire

Define the project:

This engineering task is to create an original project that both aids and helps a targeted audience and demonstrates scientific understanding, such as movement/transfer of energy. The task is aimed to be useful and purposeful, contributing to the world and most importantly original and aesthetically appealing.

Possible ideas:

-Portable suction light

-Magnetic/Hydraulic lazy tools-automatic movable shoulder rests, leg movers, arm stands, etc.

-Electrical automatic motorized light switcher (switches lights off from a distance (wireless/wired to be determined) without physically pressing them)

-Electrical motorized drink/bottle shaker

I am really interested in making the portable suction light, as it can be extremely useful for a variety of people and can be affordable, realistically made at the same time. On the other hand, the electrical light switcher is a unique idea, however, the level of difficulty to make the project work effectively is quite high.

KS-01 SINGLE BOTTLE FULLY AUTOMATIC SHAKING MACHINE | 台灣鎧瑋封口機How to Adjust a Lazy Boy Recliner Footrest: The Definitive Guide - Krostrade

Targeted Audience:

The suction light is for users who are frequently traveling, outside, staying at home, working, and are in need of portable lights. The suction is designed to cope with multiple different environments while providing a sufficient light source. Similarly, the light switcher is suitable for users that are at home or at a working space, the automatic light switcher can come in handy when saving time or simply being “lazy” at home when we do not have to get up and turn off the light.

Some constraints and difficulties the suction light will experience is the problem of electricity, if it is run by batteries then it will lack the purpose of long-term lighting. An alternate solution would be to use chargeable batteries as an electricity source, however, this also comes to the problem with designing a more heavy and bigger light in terms of components. Knowing that the whole goal is to be portable, the larger light is not practical. As for the light switcher, a major problem would be the switcher falling off/detaching from the wall it is connected to, due to the pressure, humidity, surface, or errors in the design. Another problem would be the limited distance from the remote control to the light if it is designed to be wireless. A wired connection should not be a concern and run smoothly.

 

Formative Socratic Seminar Reflection-The absolutely true diary of a part time Indian

After completing the first formative Socratic Seminar:

I believe one area of strength I demonstrated during the formative seminar was to maintain the steady “flow” of the discussion. I somewhat led the conversation in an appropriate way and encouraged others to speak,  I was also able to respectfully guide and assist others while simultaneously delivering my own opinions.

An area of improvement would be to use and discuss more literary terminologies, mentioning the greater effects it leads to and the connection to the real/Indian world. Specifically, in the third checkmark of criterion B, one of the major goals for next time would be to demonstrate a more in-depth and “detailed understanding of [the] effects [of the literary techniques/terms] on the reader/audience.” To achieve this, I would pay close attention to the contextual background behind these terminologies as seen through selected quotes and will connect them to Sherman Alexie’s childhood life & Junior’s Indian reservation,  further showing the effects that they lead through evidence from the novel and literary analysis.

 

Reading Reflection #2

Similarly to the first reflection I wrote couple of weeks ago, the book I’m writing about and is currently still reading about is the “Brief answers to the big questions” by Stephen Hawking. Up to now, I have read to page 150(about 4/5th) and is really close to finishing the book. Since this book or not a novel or a story like book, all it chapters are fact-based and focuses on individual ideas/concepts, so I would not anything has changed to an extent. Despite that, Hawking’s portray of information does somewhat changes as the book is slowly showing the basic branches of astrophysics and slowly letting the readers understand more of the concept. To clarify more, the book starts with more understandable facts, where later it builds upon the facts that were already explained to the reader to further show more complexed/advanced theorems.

The author’s use of language and structure is very special in this book, and to be honest this is one of five books I have read in my entire life of this kind. The whole book is very casual, although it is non-fiction fact book, Hawking talks in a very chill and calm voice, everything is informal and very verbalized. I am very thankful to have the chance to read this as not only it gives numerous information/theories told from a perspective of Hawking himself, but also provides comfortability and relaxation from all the serious reading I do at school. Like I have said, this book primarily talks about facts and knowledge in a calm and informal way, and each chapter has its own individual stories/concepts, such as :”How did it all begin?” and “What is inside a black hole?”. The author’s main message is to communicate facts/theories  through the perspective of himself.

I will read fiction on my next book!

Reading Reflection #1

Book read: The Brief Answers To The Big Questions

After reading Stephen Hawking’s book I have a few questions that most intrigue me: Is it possible that civilized society once existed before but was destroyed laterwards, creating this cycle of civilization? And is it possible for mankind to unlock the secret to space traveling before the depletion of the Sun? I realize these questions are not to be answered with a definite answer, but I am quite fascinated by the facts and want to ask these questions for further interest. By reading Hawking’s novel, my understanding of the world both scientifically and theoretically has changed tremendously, as now my knowledge is broadened and expanded to a much greater extent than ever before. Hawking has posed many theories, many concepts that actually make sense and are all applicable in the actual world, and on a daily basis. As from reading, I began to understand the origins of the Universe and how people like God actually play in it, thus, I began to view the world through different views and knowledge. This book is just extraordinary, I suggest all teenagers and adults to read it! It is just fascinating and will truly change your mind.

SWOT table G9

My target: By developing an organized plan every day to keep track of my homework,  I would like to achieve my goal of completing my works efficiently and with an appropriate pace. I will know I have achieved this when I no longer spend 30-40 min + to finish my homework everyday. (Depends on the workload but that’s the general amount of time.)

Circuit Project #2

My original plan included the usage of FLORA tri colors LED, which was basically a multi-color LED. However, during the making and sewing process, we found out that the FLORA does not work as effectively, therefore I made the choice to eliminate it from my project, in addition to only using two LEDs ( One blue one red) on my project.  Furthermore, I’ve also changed the location where the “yellow duck face” is going to sew on, before it was supposed to be under the FLORA since now the FLORA is out of use, I re-located the piece on top of the button “B”, which is on the right.

Honestly, I’ve learned a lot during this project. First of all, I consider this project as a fail, however as Ms.Kim says it: “Fail is First. Attempt. In. Learning” I might as well take that into consideration.  A lot of things weren’t going as planned and were obviously going the wrong way. The FLORA led, for example, was supposed to be used in the project to further shows the project’s full potential, but that never happened due to the FLORA not connecting well. The orange hat was never intended to be there as it showed clumsiness and ugliness to the project, it was an urgent yet bad-produced re-cover for a stupid mistake I did when I accidentally chopped off 1/4 of the projects head, making it look almost “bald”. The same goes for the red eyes, I still regret making them before I sewed on the LED, it looks horrible and super ugly as well. The planned intention was to cover the LED with red eyes and have a slight hole to let the LED bulb come out and illuminate. My brainless mistake made me forget to sew on the LED first, now it looks super creepy and ugly. Lastly, I definitely need to remember to take all the materials I need home since my original plan was to velcro the LED pack on the back of the project, but I clearly forgot to bring the velcro home.  If I were to do this again or in a somewhat different way, I would definitely be careful of what I do, always double-check, and don’t make silly mistakes, and yes, next time I will for sure make it look way prettier than this ugly “thing” I’ve created.

These are pictures of my final project, both front, and backsides. As you can see the artistic features are clearly substandard, sorry for that I will definitely do better next time!

Just FYI, the LED lights up by clicking the button that is hidden under the yellow felt button piece.
