Reflect and Exhibit

For this Ignite week project, I choose Fandom, create  because first I like the book from Percy Jackson story its good its awesome and its one of my favorite books. I thought I grew in  the skill of making because I had to make a difficult sword blade by having a wood core and stick two sword shape foam and glue it with super glue. I enjoyed making all the fun stuff this week like the part of my sword / I found it challenging to learn how to make the blade of the sword this week.I think that this skill will benefit me in the future because I could use the skill to maybe make something useful or to help me with my work.Overall, this Ignite week helped me grow because I learned a lot of stuff like how to make a sword with spare pieces  and made new friends.

Express It: Create and Improve

Making my first prototype was challenging, because I had a few mistake like having a cardboard prototype that was only half of the size of my final one. Also I made the guard of my sword too small, and a challenge I had is the cardboard pieces I found were all not the right side for my sword blade. From all the mistake I learned from prototype 1 I got a better try for my final product.

Express It Develop and Plan

This is my first sketch

this is my first prototype

While making my sketch I had a idea by building sword with part, like have a wood sword in the inside and having part of foam covering the model in the inside. I got this idea from a video call Odin makes, he make sword by putting parts of foam to make the techniques of the sword . To make my prototype I use cardboards and to make my final product I could use wood and foam.

Make It Define and Inquire

My fandom is Percy Jackson sword: Riptide

The series of Percy Jackson inspired me because it was a very  good book and it is my favorite book, so I want to make a fandom of it by making Percy sword Riptide. A problem that am struggling with is what materials am going to use to build my sword Riptide, after I finish make the design I decided to make a wood model of Riptide and rap it with foam to finish the sword.  However, I think it might be difficult to to rap the foam on, because on the outside of Riptide it has many detail to make.

 

ONEDAY J . Life E . Size N . Board G . Games A . Design Challenge

I decided to make jenga, because I have two sets of jenga at home

but I never played a life size jenga befor. So I decided that I want to make a life size jenga with my team.

I did well sanding that block which I was doing all day, it was hard sanding 54 block of wood we used about 15 sheet of sand paper. I learn that having a team is better than doing it by yourself because making all that parts of jenga without help is impossible because I spend all day but I only finish sanding about 20 block. Challenges that I faces is we were not able to finish sanding in time and don’t have enough sand paper to use, but we solve it by sanding with more people and asking the teachers for more sand paper.

I hope that I could change from the beginning so I trust each other and we could finish faster.

Drop 1 Test

<Insert Image>

Our team constructed the first design using Tape, Paper Bags, glue and straw .  Multiple drops took place and we noticed that I notices that the box was going sideways when falling down to the target and it was always flying out of the reach.

In order to improve our design, we paid attention to area where it failed. The following “FAILS” happened during the drop:

1.fly into people in the working space

2. parachute not inflated

3.The package land 75-115cm away

we learned that the we need to improve on our accuracy

Some things also went well. Big successes include hitting on the force plate and having a success on soft landing.

For our next design, we will improve upon the first prototype by we will improve by putting a hole in the parachute or make the package more heaver.

River Field Study – Data Collection 4

2019/1/25 me and my group went to the Wenyu river to collect data of the PH, to see how much it change from 2018/11/20.

Photo Caption: These photo is about the place we went to collect our data for changes from station 1 and 2

Date tools Location 1 Location 2 Location 3
2018/11/20 PHS-PHT —- 7-7.2 7.5-7.5
2019/1/25 PHS —- 7.2 7
2019/1/25 PHT —- 7.2 7.2

In January, the  data we collected was 7.2 -7 for PH S and for PH T it was 7.2-7.2. I notice that the data didn’t change a lot from last time because it was still 7-7.2 . Next time we collect data, I wonder if the data is going to stay the same or have a huge change like 5-8.

Drop 0

Title of Blog Post: Test Drop 0

In Project Collisions, I am creating a system to deliver SkinCare 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 9.5cm by 5cm and 10cm was dropped from a height of 5 meters. Below is a photograph of the package:

The package will hold Skin care product. Inside, items are organized like this: a box of skin care inside is the things that is order.

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.

During the drops, I noticed that I notices that every time the box goes down we have a 60% of chance to hit the target i wonder if the box is going to hold when it hits the ground  . The following data was collected:

The average time it took for our package to fall the 5 meters was 3-5sec. Using LoggerPro, we plotted out the fall of the package.

<insert image – screenshot – from LoggerPro>

It was very fast when it was release from the top and falling down

A force plate at the bottom of the drop was used to collect data on the impact force of the package. Our group was good I think because we have a 3 out of 5 which is a 60% to hit . This is your land on the point! If you were, include one screen shot from the LoggerPro data that shows the impact>. As a project metric for accuracy, we want our project to less or equal to 60cm

The average force on impact was 45 newtons. As a project metric, our group has decided to for project drop 0 we want to reduct the impact by more or equal to 20 newtons.

Summary: Project Metrics

Our team has decided that the three most important criteria to design towards are accuracy Below, each metric is described and the goals were determined by data from Drop 0.

  • Metric 1: We hope that the accuracy we have are not far from 60 cm
  • Metric 2: To use reusable material
  • Metric 3: soft land with parachutes to reduct the impact

Our group is now building the first prototype. I hope that we could design a package that could have a soft land of 15 newtons and have a accuracy of 85% .

EGG Drop Reflection

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 was a box with paper around it.

Then, working in a group, we decided to combines our idea together and build it so we took Justin idea and make balloons as a landing, and took my idea to make a cover for the egg.

As the egg was dropping, I was afraid that the egg will break and we failed,  but I was also excited what will happen like will it survive or it will die.

Our design was unsuccessful because we didn’t have all the time we need so we only finish half of the product.

Next time, I would make the plan easier so we could finish making it in time, and I would make the landing in paper so we have more money to buys others.

Project Collisions is using the idea of drone delivery. During my research, I would send cloth because its not easy to be damage, and its light.

Through this project, I hope to learn what the good part about drones deliver and how its compare to human delivering system.

HOPE

Jack always wanted to live a happy, endless life with wealth and freedom. living with with his family was the best thing, but the world is depleting and jack and his family is having a hard life but they are living freely and a happy life. Until one day his brother is killed and his parents were capture! Will he be able to save his parents or not?
