AmyLi_Iteration Project

Before starting the project, I knew I wanted to do another iteration of the 3D project. I knew that the phone I made in the beginning looked unproportional and that I wanted to make it slightly better. Initially, I wanted to create a 3D action figure that uses a LED light, but I did some more brainstorming and decided to design a phone case with a fidget component attachment on the back. I wanted to do this because I wanted to create a more proportional 3D print and give it a function. I figured that many people carry their phone on them at all times and when it comes to people fidgeting, it’ll be more convenient for people to have a fidget component attached to their phone so that they can use it without having to carry both their phone and fidget toy.


While working on my project, I took my current phone case and measured the dimensions so that the 3D print would be proportional. Additionally, I used autoCAD to create the phone case because it has more available features such as fillets, extrusions, and the ability to assemble multiple parts.

I decided to draft a phone case by combing a component of the fidget cube and placing it at the back of the phone case. I measured the approximate comfortable distance to place the fidget component on the case. I ended up using the circular disc from the fidget cube because it produces no noise and it isn’t bulky, so it doesn’t interrupt the flat surface of the case.

I sent the 3D print through multiple (4) times, but I received an error for printing the circular disc or the fidget component at the back of the phone case. The case came out to be the correct proportions, but I couldn’t figure out why the disc kept on failing. I think it was because its too small for it to print, so I might have to create a wooden disc through laser cut or hand make in the woodshop. Other than that, the phone case come out with the correct proportions. Overall, it was nice to create another iteration of our old projects. The case came out fine, but it was stressful trying to create multiple 3D parts. I tried to send the print through so many times that I ended up getting frustrated.

Pom pom robots

In my initial concept, I wanted the pom-pom bot to drag itself from point A to point B and I planned on giving it a set of legs to help move it forward. I only planned on using popsicle sticks because I never really considered it. To me, it seemed slightly unnecessary to decorate it, I wanted to focus more on the coding and the motion of the pom pom robot since I didn’t have prior coding experience. I forgot to take a picture of my initial model, however, it had two popsicle sticks taped on each motor. This didn’t work because the robot wasn’t able to balance on itself and it constantly fell over. I figured that I had to create better leg support for standing and probably a stronger grip so that it can pull itself and glide against the table. I also had to change the code so that the robot moves forward with one motor and the other motor goes the opposite way so that it works like legs in motion.


My second and final prototype worked but not exactly the way I wanted it to. I changed the code so that each leg of the robot moves at different times. I also added a popsicle between the two motors so that they stick together and works a little bit of a balance. The final prototype moves forward but also jumps upward and forward, thus dragging and bouncing the robot forward. I added more popsicle sticks to the motors so that the robot balances and stands on its own. I also added hot glue to the bottom on the sticks so that there was more traction against the table. I also ended up putting a little feather on the robot for a little bit of bedazzle. Overall, it was a fun project, I would definitely spend more time coding it and making it move more smoothly and make the robot look more finished.

Arduino Introduction – Amy Li

Before starting the actual project, we learned the basics of using Arduino such as the basic layout of the ground, power, and voltage. Then we started tinkering with the Arduino software application while using LED lights, the breadboard, and sensors. Since I’m an industrial design major, I didn’t have much coding experience within my major. Figuring out where to put the LED lights and wires weren’t too difficult; I thought it was pretty logical. However, we later had to create a code using LED light to signal SOS. I’ve been slowly trying to teach myself some JavaScript through my free time so figuring out the code was slightly more difficult, but I wasn’t entirely lost.



During class, I started tinkering with the ultrasonic sensor. It was an interesting process because I never previously learned how to code using Arduino. I entered a couple of codes and couldn’t get it right, but since Arduino is such a popular program, I was able to use Google to search up some existing codes which ended up working. I thought that the Ultrasonic sensor was an interesting tool. I thought I could create a program for users to turn the t.v on and off or switch channels using voice command. I thought that it was an interesting concept until I realized that Alexa from Amazon was already capable of this function. I ended up searching for other existing sensors and found the Arduino WiFi Shield.


In my industrial design class, I had the idea that I wanted to create a lamp where users can turn it on and off using WiFi or even adjust the mood light setting of the lamp using their mobile app. I decided to combine my previous idea of a WiFi activate lamp with the Arduino WiFi Shield. Ideally, this would allow users to turn the lamp on and off using WiFi. This is highly beneficial and user friendly because the user can turn the lamp on or off if they’re in a different room. Alternatively, they can switch the lamp to a mood light setting and adjust the brightness without having to get up from their bed. I think it would be really interesting to pursue this for my final project by designing a lamp and then coding it to work properly. Overall, coding the Arduino is very interesting and pretty fun, I would be interesting in purchasing a kit and tinker with it

some more.

AmyLi_Soft Circuit

In our discussion section I created a embroidery of the starbucks logo. While trying to find what I wanted to embroider, I found a picture of Bender from Futurama and wanted to use that as my embroidery, but then realized it was a too complicated to do in the duration of class. I settled with the Starbucks logo and it was a pretty interesting process. I liked it alot that I decided to make it into a canvas stretch in the woodshop. We also learned how to make small bags using the sewing machine.


During the project, I decided to create an embroidery of Bender and make his metal bottom shine and cigar shine. However, the images gathered of Bender are too complicated that the details wouldn’t come out when using an embroidery machine.

I ended up choosing to do a spongebob meme of evil Patrick. I wanted to create a sort of fun project related to pop culture so I ended up making a coin purse/bag with Patrick from spongebob embroidered on the front. When I first started doing the embroidery, the machine gears weren’t tight enough so the back of the patch got a little bit fuss. I decided to restart the print and adjust the tightness a little more.

The embroidery came out pretty well. I created it in hopes that Patrick’s eyes would light up, but I later found out that the conductive strings were sewed too closely to the positive and negative that I short circuited the battery. If I were to do this again, I would definitely make sure the lights worked before sewing everything together because its difficult to fix the lighting problem after I sewed everything together.

At the beginning of the project, I explored different design platforms such as tinkerCAD, Sculptris, and 3D scanning. During class, I created a castle using tinkerCAD. After having experience in SolidWorks, I strongly disliked tinkerCAD. I hate that I am limited to using shapes on a grid. It is very restricting and difficult to create organic forms and curves.

Then I switched over to using Sculptris and experimented with the software and created an ear and colored it. I liked how I was able to create outrageous organic forms, but it was difficult getting geometric shapes and dimensions into the structure.


I was also able to use the 3D scan and scanned myself. I thought that it was an interesting tool, but I didn’t want to scan an existing object and make something out of it. I wanted to make an original design.

When I first started the project, I knew I didn’t want to use tinkerCAD because it was too restricting and Sculptris didn’t allow me to dimension my forms. I decided to use SolidWorks because I was able to fillet my object, create extruded cuts, and haves specific curves and dimensions. I started off by doing some research on cell phones because I noticed that phones have the same rectangular structure for many years. A couple of problems I identified was that phones are flat and that it doesn’t fit into the pockets or conform to the thighs. I ended settling on a curved phone structure that conforms to the thighs with an interchangeable camera lense.

While working on the project I actually started off with using tinkerCAD to create the curved phone structure, but it was too restricting. I couldn’t join two rectangles and have the form merge and create a curve so I switched over to SolidWorks.


Overall, the project was slightly more challenging because I had to find a product that I wanted to change and conduct some user research to figure out what needed to be changed in terms of cell phones. I chose to change the overall structure of a phone because I’ve noticed that flat rectangular phones are somewhat bulky and don’t conform to the thighs. I also created a curve on the bottom of the phone so that people can use it as a supporting grips since most people use their pinky to prevent their phones from slipping. I also wanted the phone to have an interchangeable camera lense so that the user can take better quality photos rather than settling for a phone camera with one picture quality option. I think this project really makes us think about the user of the product and figure out what changes we can make to a product that’ll make the product more user friendly. I was able to learn a lot more about user preference.


I also learned that 3D print sometimes fail, but mine didn’t necessarily fail. The back of the phone frame was slightly more rough than I wanted it to be. Additionally, the portion and size of the print wasn’t as I expected and it was a bit smaller than I wanted the actual product. So if I were to redo this, I would adjust the size of the product and make it more proportional.

Amy Li Copper Tape Origami

Before beginning my project, I started off by looking at the copper tape structure I made during class. I kept in mind that I needed to have the positive lights attached to the positive battery and the negative attached to the negative side of the battery. I was pretty excited to start this project, but I wasn’t sure my lights would actually light up.

While working on my project, I started off by looking for inspiration online. I thought about doing a pop up story that incorporates the LED lighting element, but it got too complicated so I scraped that idea. Then I started looking into origami and decided to create a bat. I thought it would be interesting to have the bat’s eyes glow. It was difficult getting the LED lights to work and show though the construction paper, but I fixed that by moving the lights further up so that it shines through a crack.

Overall, it was a fun project, but I think I could’ve done something more grand and interesting. An origami bat is cool, but I also wanted to make a pop up book with moving characters. Thus, if I was given more time, I’d definitely do something more unique and interesting.

Amy Li Project 2 Sticker

I made a sticker of a cracked skull with blood spilling through the cracks and an eyeball protruding from the socket. I created this because I liked skulls and thought that it was  an interesting visual to recreate.

While working on this project, I enjoyed the process of finding photos that would match one another, such as the socket and the style of the skull. Eventually, after I put the entire piece together, I was told that the skull had too many lines and it would be difficult to print. I later got help from Duncan and worked around the problem, by printing the skull as a slightly larger sticker and having it as multilayer. It was slightly difficult removing the excess white parts of the skull and then transferring it over to the black background, but it worked out perfectly once I got the hang of it.

Overall, I loved how the skull sticker came out. Duncan helped a tremendous amount in helping me troubleshoot any problems with printing the layers. Sticking each layer on top of each other was the most fun. It was especially rewarding to see that the sticker came out exactly how I wanted it to.

Laser Name Tag Amy L

I wanted to make my name tag look like a t-square because it’s an important tool used for drafting. However, the proportions of the t-square on the screen was proportionally off and I figured that the print my name would be too small, so I decided on a new design. I noticed that I’ve been using the Shaka, or the ‘hang loose’, hand gesture quite often. It’s a friendly gesture often used to say hello or goodbye. Thus, I decided to re-create the Shaka hand gesture and use it as a symbol for my name tag.


A problem I ran into was that I only wanted to cut the shape of the gesture, but the laser cutter ended up cutting the hand into multiple different pieces. I worked around this and decided to spray paint the outline of the hand black so that the hand is more apparent. I also glued a back panel piece to the hand so that the pieces stayed together. The name might appear crooked, but it you were to tilted the name to a horizontal position, then the hand would be at its correct position.

After finishing the project I would’ve changed the print so that the name tag isn’t in separate pieces. I would prefer if the inner part of the hand doesn’t hollow out, however, it worked out because I wanted to spray paint the lining of the hand as well as the back of it. I improvised and reinforced the back of the hand with a piece of thin wood that’s also in the same of the hand. Overall, it was a fun, easy, and quick project.
