Make it: Reflection

One of the challenges for me was to put on the wheels onto the skateboard, I asked for help and put on the wheels. Another challenge for me was to spray paint the black on the front side of my skateboard, because of the paint we need to spray paint it in a distance so can’t be too close and can’t be too far away, it was kind of hard to control the distance.

Some skills that I developed was how to spray paint correctly and to put on wheels on a skateboard. A highlight for me this week is  • What was the highlight for you this week?

Express it: Create & Improve

During this create processes I found that the idea pray painting the front to black did work well, it saved time, also something didn’t work well is that taping the edges of each triangle takes too long to tape then color the inside. During the improve processes I decided to color each triangle first and then color the background black so if there is something I missed or did wrong while painting the triangles I can fix it after when I’m painting the black background and it really saved time for me.

Something that is challenging for me is to color the thin edges of the triangles with black paint. But after I covered up some of the edges of the triangles so that I won’t paint into the triangles. The prototype helped me when I drew the triangles and it helped me to measure how big the words should be or is it in the center.

Make It: Expresses It

Some of the materials I use are tape, some color acrylic painter, the plane skateboard and a transform paper to transform my design on the graft to the board.

These are some pictures of the materials and my board.

This is two of the colors that I am using to color the triangles.

This is the tape that I use to cover up the edges of the triangles when I paint it.

This is my board now.

To generate ideas, I looked up pictures that others did online and choose a pattern and colors.

What areas of this project do you think will be challenging? Why?

  • I think that making the sketch on the skateboard might be a challenging thing for me because I need to draw everything I designed in the right place on the skateboard without changing anything.
  • Another thing I felt challenging is when I need to choose from different very nice designs.

Sewing for donation Create and Improve/ Reflection

Create and Improve:

Create:

I created this baby blanket that has white sides on each side.

 

This is my final product.

 

During the project create I first made the two short sides but after I was done I figured out that one of the sides wasn’t as it should be so I decided to redo the side and although it took me longer than I was planning I still enjoyed the time of learning.

This is a closer look at the edges I sewed.

Improve:

I was improving my plan by looking at videos online and searching for different sewing patterns.

These are some example ideas that I found online.

Reflection:

I think I did well on learning how to sew on a machine and making my product when I was still learning.

I learned how to sew and work with a machine also I learned how to undo the sewings that I had finished.

A challenge that I  faced was to learn how to use a sewing machine and also make my product with it. Another challenge that faced was that I needed to finish my product just in one day and that I needed to change and redo some of the mistakes that I made which took a long time.

I think that One-day is important because during One-day we can focus on one thing that we are doing or making for a whole day which means that there is more time to make the product also we can be choosing one of our favorite things that we would like to do all day so it makes the day fun and exciting.

Sewing for donation Develop and Plan

Develop and plan

I am looking forward to make a double-sided baby blanket that has two different colors on each side. In order to make a blanket, I will need soft fluffy texture material and  I need two colors to make each side.I hope to sew the side together and maybe if I have time I can make decorations from knitting or crocheting. Also, after sewing the two sides together I will sew the edge with the other color or texture. Another option is to knit or crochet the edge together. In order to do all these things, I need to learn how to sew with sewing machine.

Materials:

– Soft, fluffy texture material( two colors)

–  Sewing machine

– Maybe knit or crochet decoration

Egg Drop

On this 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 using

1 A4 paper, 1 newspaper, 8 pieces of strings, 3 sets of rubber bands, 3 straws, and 2 binder clips. Our design is egg wrapped with 1 full sheet of newspaper, then connect also stable the egg wrapped with newspaper with the parachute made from four strings connected with an A4 paper, which made the parachute. 

Then, working in a group, we decided to add a parachute to slow down the speed of the egg when dropping, then we decided to wrap our egg with a full sheet of newspaper to ensure that there is a protection for the egg, we also added rubber bands around the wrapped egg to stable the wrapping, last we put 2 binder clips on the top and bottom of the wrapped egg to kind of make a stand for the egg.

As the egg was dropping, I was really nervous because I was worried if our design was save for the egg but in the same time, I was very excited too because I really want to see if the egg is saved or not.

Our design was successful because we slow down the speed when its dropping and wrapped the egg with multiple layers to protect it.

Next time, I would make a bigger parachute so that we can slow down the speed more.

Project Collisions is using the idea of drone delivery. During my research, I learned that delivery with a drone can deliver you many different things to you. Through this project, I hope to be able to learn more about the different things that can be delivered with a drone. Also, to learn how can the package land soft and be accurate.

This is a picture of how our egg looks after being wrapped with layers and with everything ready to drop.

January Field Study Collections- 4

What was the date? Where did you go? What was the purpose of the trip?

Today, January 25th we went to the field again to collect data. The purpose of this trip is to collect different data from different times in a year and look at the difference between each time.

This is one of the pictures of the mushroom tree that I took today at field study.

This is another picture i took at field study today.

This is how the big tree looks today.

This is what it took around the big tree now.

This is how the glass patch looks now.

This is the data table that has all the data today.

In January, the mushrooms on the mushroom tree decree from 101 to now only 71. Also, the big tree, we notice that there are no leaves left anymore on the tree, the color of the bark is still dark brown but the human impact around the tree decreased not much but from 9 to 6. Other than that, at the glass patch, the number of glass has decreased from 233 to only 153, also we notice that the ground around it is now flatter and packed comparing to before that is softer than now.  I notice that all the data has decreased compared to times we’ve been before. Next time we collect data, I wonder what will be more or less at the field.

Sewing for donation Define and Inquire

My goal in this one-day project is to make a useful product that can be donated for kids in need.

My hopes for this one-day sewing donation is to learn and improve my hand sewing skills.

Define and Inquire

Discover:

Since it is winter now and we have big winter jackets but at the same time, there are also many children suffering in the cold. So I think that if we all help do something for them they can be warm and comfortable too. We decided that making things that can be useful for them will be the best to make and give form us.

But time might be a big limit for us since it is only a one-day project some of our product might need more time than others do so project unfinished is a limited problem for us now. Another problem is that when you need to make something when you’re still in the prosses of learning might be another difficult thing to do as learners in sewing. Other than limited for time, another thing is that the materials that we have could be a limitation for us.

Empathize:

This project is all going to give to a charity and donating to children that need this to keep warm throughout the winter.

Analyze:

In order to do these for donations, I need to learn to sew and learn about the materials what we need to make winter wears for the children. Also, we can get inspirations from the internet, look up for pictures and videos to learn how to make different winter wears.

Drop #0

In Project Collisions, I am creating a system to deliver fast but healthy food 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 in its fall.

 

For Drop 0, a package with the dimensions of 12 meters, 14 meter, and 16 meters was dropped from a height of 5 meters. Below is a photograph of the package:

This is a picture of our package.

The package will hold some hot food, a burger, some juice or drink, some fruits and maybe some little snack such as chips. Inside, items are organized like this:

This is a quick sketch of the inside of our 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.

<insert image of final procedure>

During the drops, I noticed that the speed of the package dropping is very fast so it means that if we want to add a parachute it needs to be strong but not too heavy for our package.  Also, a wonder that I have watching was how can we make sure that our package lands softly and slowly with a parachute. The following data was collected:

This is our data table which records the force that was applied when dropping the package.

The average time it took for our package to fall the 5 meters was____________________<amount of time in seconds>. Using LoggerPro, we plotted out the fall of the package.

This is a screenshot of the data that’s collected from Logger Pro.

This is the whole video of our drop.

IMG_0120 

A force plate at the bottom of the drop was used to collect data on the impact force of the package. Our group was okay on how accurate we drop the package we missed on the plate for once out if three times of drop.  As a project metric for accuracy, we want our project to land right on the force plate in order to make accurate data.

The average force on impact was around 110 to 150. As a project metric, our group has decided to make sure the landing is soft and not out of the place too much, more than 2 meters.

Summary: Project Metrics

Our team has decided that the three most important criteria to design towards are the landing to be soft and safe, the food needs to be still hot and not soft and spilling out, and also being accurate when landing.  Below, each metric is described and the goals were determined by data from Drop 0.

  • Soft landing, land with a force of 30 to 50newtons.
  • Accurate landing, we need it to land on the force plate.
  • Food is separated, not soggy, not combined.

Our group is now building the first prototype. I hope that it helps us see and learn more about the mistake that we have and improve to make it better and better.
