"Stars can't shine without darkness"

During Ignite Week – Express It! I filmed time lapse, videos and pictures of a day in my life.   To complete this project, I had to film segments of what I did throughout the day. I set my phone up on a tripod so the video won’t be so shaky. After I filmed all my videos, I had to put them all together using imovie. Using imovie, I was able to edit and trim my videos along with adding music to it. During the process, I learned that imovie is actually really helpful with editing. I learned how to change the speed of clips in order to make my video more successful.

 

The L21 area that I focused on was to choose and use different strategies when trying to solve a problem (searching for tutorials, trial and error, asking a friend, asking an expert because I thought there would be a lot of challenges on the way of creating this video, so I wanted to use different solutions to solve it. To meet my goals in this area, I used imovie to edit my video and used my phone to film. For example, I was able to use different editing techniques to make my video better. Also I tried using a stabilizer in imovie to make my video less shaky.

 

Some skills that I gained through this project include…

Express It: Blog Post 2

During this project, I will need to use my phone to record videos and timelapses of my day. Along with that, I also need to use a tripod to secure my phone and imovie to edit my video. For this project, I will need to learn how to cut and trim segments of my video, this way it won’t be too long for the final video to be boring. I want to try experimenting with speed of clips to help me level up my skill levels. This way, my video won’t be too long but will still show parts of my day.

 

My Day: Post 1

For this ignite week project, I am in the group of “My Day”. During this time, I am filming a video to show a day of my daily life. Through this time, I want to explore different ways and different ideas that I could incorporate into my video. By the end of Friday, I would want a full video of what I did throughout the day. I want the video to contain different activities I did. Also, I hope the video can represent my day and what’s it like. I hope it can inspire others as well to try new things.

Top Chef: Appetizer

For appetizer, we decided to make coconut shrimp. We feel like it went really well because everything went as planned. the shrimps turned out really well but I think we could have worked on plating a bit more. Next time, I would like to improve by being more prepared and bringing more ingredients with us. This way we would be able to have more options.

For main course, we made pad thai. It didn’t really turn out as expected and the noodles were kind of gooey. It wasn’t what we imagined and I think it could’ve been better. I think the egg was what made it turn out like this. We were supposed to add in the egg before the noodle and everything else, however we added it in last.

So, the noodle and the egg combined together and the final product was what it was supposed to look like. Also, we didn’t have lots of the vegetables that we needed for pad thai. Next time, I think we will have more experience and hopefully make it better.

For dessert, we made mango sticky rice. It was meant to turn out like this:

But I think something went wrong in the process of making it, so the rice didn’t turn out as dry as it was supposed to be. I think one thing that could’ve went wrong in the process might be us using brown sugar instead of white.

 

 

Project Collision Final Blog Post

Looking back on Collision, I learned that there’s always room for improvement and you can always make the design better. I say this because we had to fix our designs multiple times in order to get our final product. Also, it made me think more about the design. It made me more engaged in the project, think deeper in how to fix problems and overcome obstacles. Before this project I used to think that you only need a parachute and it will allow the package to slowly descend, have a soft landing and have perfect accuracy. However, through multiple designs along with collecting data, I realized that having a parachute lowered our accuracy and our speed didn’t really change in our first design. For example, on our first design, I noticed that we had such a tiny parachute so it wasn’t able to catch enough air to let us have a soft landing. Yet when we changed into a bigger parachute for our second design, there were much more of a soft landing. Another thing that helped me develop was the realization that parachutes can lowered our accuracy. I think this is because the parachute drifted to one side. So, for our final design, we made the parachute longer instead of round. This way, the parachute didn’t drift as much and had a straighter landing. Looking back on project Collision, I realize that testing with multiple designs is very important in creating a reliable system. For example, when we had our first design, so much things went wrong. Our parachute wasn’t able to successfully slow the speed down, so collecting data helped us figure that out. Through the design cycle, we were able to fix our mistakes as well as improve our design. We were able to look at the changes made through our data table and could add on to our designs to make it better.

 

Drop 1

I was absent for the whole time while my team did drop 1. But from what my teammate told me, this is what he designed. He constructed the first design using a plastic bag, strings, rubber band, and wooden sticks. Unfortunately, he was only able to do the drop once since the parachute came off.

In order to improve our design, we paid attention to area where it failed. One of the biggest fails my teammate had was that he didn’t attach the parachute to the actual package. So, when he dropped it, the package just fell without the parachute. It missed the camera, and the force plate so there were no ways to collect data. Because of this, the drop wasn’t as accurate and it didn’t even hit the table. Instead, the package landed about 15cm to the left side of the table.

The biggest success was probably not breaking the package and the things inside, after all it didn’t have any protection and the parachute wasn’t able to slow the speed down.

For our next design, we will improve upon the first prototype by attaching the parachute to the actual package, and to make the parachute bigger so it can catch more air.

(sorry I don’t know a lot of details since I wasn’t here)

Drop 0

In Project Collision, I am creating a system to deliver portable charger by drones. The drone will release the package from a height up to 10 meters and my job as an engineer is to develop a solution so that the package is protected during the fall.

For Drop 0, a package with the dimensions of 13x9x8 was dropped from a height of 5 meters . Below is a photograph of the package:

The package held a stapler for drop 0. But, our final product will hold a portable charger. Inside, items are organized like this:

drop 0 package

The purpose of Drop 0 is to get baseline data about our package. The group developed a testing procedure so that we can be consistent on how data is collected throughout the design cycle.

  1. Secure product
  2. Prepare the box at 5-meter point, (make sure the bottom of the box is at the 5-meter point.)
  3. Line the package up at the silver line
  4. Turn force plate and cameras on
  5. Start logger pro
  6. Make sure no one is standing in drop area
  7. Talk to partner when ready to drop
  8. Drop the box while starting the timer
  9. Once the box hits the target stop the timer, camera and logger pro
  10. Take a picture of data on logger pro
  11. Airdrop videos from camera to computer
  12. Check the condition of box and the inside
  13. Repeat procedure for at least 3 times
  14. Record data in data table

During the drops I noticed that the package accelerated extremely fast because nothing was really there to slow the speed down. Most importantly, the package smashed down and bounced a bit at the end resulting in damaging the package a bit on the outside. Despite speed being one of our metrics, we do not want it to damage our package or drop down like a rocket.

The average time it took for our package to fall the 5 meters was 466 centimeters/second. Using Logger Pro, we plotted out the fall of the package.

A force plate at the bottom of the drop was used to collect data on the impact force of the package. Our group was pretty successful at hitting the target. We dropped our package four times and we were spot on with hitting the target every time. However, the force of the impact changed dramatically every time. I think this occurred because each time, the package might have hit the force plate at a different angle which resulted in different force.

First drop of Drop 0

As a project metric for accuracy, we want to design a package that can land within 30 centimeters within a target similar to a force plate (this package would be dropped from a distance of 10 meters).

The  force on impact of our first time dropping was 138.5 N. As a project metric, our group aims to reduce the amount of force excerted on our package by 40%.

Our team has decided that the three most important criteria to design towards are accuracy, soft landing, and speed

Below, each metric is described and the goals were determined by data from Drop 0.

Our first metric is accuracy, and by that we mean the landing is somewhere around the area that we expect it to land. From drop 0, our accuracy were spot on. Using the force plate as our target, we were able to hit it successfully every time. However, for the final drop, our goal would to have a landing 30 centimeters around a target similar to the size of the force plate.

Our second metric is having a soft landing. We do not want our product to end up being broken or smashing down onto the ground, so a soft landing is needed. For our drop 0, there was a large range from 18.1N to 257.5N. Our goal would be to let the landing be somewhere from 50N to 130N.

Our final metric is speed. No one wants to wait 30 minutes for a portable chargers to land and be delivered. So, we want to have speed and to let our parachute drop down quickly. This doesn’t necessarily mean that the package has to accelerate super fast but we don’t want to let the package hover too much in the air. Our final goal will be to let there be a landing around 2-3 seconds.

Our group is now building the first prototype. I hope that our parachute can successfully slow the speed down for a soft landing. But at the same time, I do not want the parachute to glide and drift around which can lower our accuracy and speed.

River Field Study – Data Collection 4

On January 25th, we went back to the Wenyu river. As usual, we had to collect data of the different sites we set up.

In this photo, there were only a tiny bit of plastic. It shows that this areas plastic decreased by a huge amount.

In January, the amount of plastic decreased to a point where there were nearly none. It was much easier to count now compared to the first time we collected data. I notice that the amount of plastic keeps on decreasing. When the weather started getting cold, there were about 16 pieces of plastic, however the number dropped to 5(this time). Next time we collect data, I wonder if the number is going to continue to decrease, or would it finally start increasing?

 

 

Project Collision

On Monday, January 7, I began Project Collisions with an egg drop. This design challenge was to drop a raw egg from a height of 5 meters without breaking it. A material list with items to purchase was provided. My first design wasOn Monday, January 7, I began Project Collisions with an egg drop. This design challenge was to drop a raw egg from a height of 5 meters without breaking it. A material list with items to purchase was provided. My first design was a parachute using A4 paper along with a box on both sides to support the egg. Since we were only allowed to use the materials on the list, I decided to use paper clips to secure everything.

Then, working in a group, we all agreed on using a parachute to slow the speed down in the dropping. Although we did change our design a bit, by adding all of our ideas together. Instead of using a box to put the egg in, we decided to use a cone, then we added scrunchies in it to secure the egg in place.

As the egg was dropping, I was so nervous thinking that the egg would break since right before the drop, the paper clips fell out of position. When the egg landed with a big thump, I thought that the egg definitely cracked, however when we opened the package, the egg was completely untouched.

Our drop was successful because the guts didn’t spill out. Also, there weren’t a lot of cracks on our egg.

Next time, I would definitely try to use more paper clips to secure the parachute in place.

Project Collision is using the idea of drone delivery. During my research, I have learned about how drones have helped communities in different ways. Like the company “Zipline” uses drones to deliver blood to help people in severe medical conditions. I would like to deliver portable chargers so people can charge their phones at any time.

Through this project,  I hope to combine everyone’s idea into one and use critical thinking to help achieve the best.

Twisted

From being extremely rich and wealthy, to suddenly being filthy and poor. On the Island Beijing, Caroline and her best friend Natalie is facing a huge crisis. They used to be the best and richest people in OUP, but now everything changed. The Island of Beijing is running out of water and facing a huge drought, and they’re to blame.  Forced to evacuate, they’re now living in a faraway camp. Will Caroline and her family be able to survive or are they going to be facing serious problems? 

Ivy Y-Scifi final

Through this writing, I developed more skills to add into details. I learned to use setting, weather, and descriptions to match the mood of my writing. I also tried to add moves to my writing to make it more interesting.

This is my final TinkerCad print:
