Ignite Week: Express It: Reflect

What Are Some of the Skills That You Developed?

Finishing up Ignite Week, I am looking back and processing some of the skills that I have developed. I have learned how to spray paint, which is really cool. I have never ever done it in my life before this week and I always thought that you just hold it in place. Now I know that you NEVER hold it in one place or it will drip and will will have to much spray paint. I also learned how to use paint markers. Before this week, I thought that all you did was open the cap and draw. No.  Turns out, you are supposed to shake it VERY WELL before using to get the paint moving around.

Ignite Week: Express It: Create & Improve

What Worked and What Didn’t? Why?

Wrapping up Ignite Week, I am looking back and seeing what worked and what didi not. The thing that worked the most was the flames. They were an original idea and is now part of board. Something that also worked was the black spray paint. From the beginning I liked the idea of a black background and so I kept it. Unfortionatly, something was bound to go wrong. That mistake was the word, “YES” and the two sentences that followed. I realized that they would take too long to do and what would I color them? Sadly, they were a fail.

What Was Most Challenging and How did you Overcome This?

There were a few challenges but the biggest one was that the flames took FOREVER, to color in. I had to color dark orange, then light orange, and then smear them together so that they looked like flames. Then, on top of that, I had to paint the rest of the flames yellow and then smear that with the orange. The overall product looks superb but that part was very challenging.

Ignite Week: Make It: Express It

What materials and techniques will you apply?

Continuing on with Ignite Week, we are progressing on our skateboards. I changed my plan from the words to a flaming cobra. The materials that I will use on my skateboard are the skate deck, wheels, paint markers in different colors, pencils, tape,  spray paint, erasers, printed pictures, and tracing paper. These all contribute to making the skateboard. I use the pencil to trace the printed images onto the board, and the tracing paper helps with that. After tracing, I will cover the traced parts with tape, spray paint the board black, and then wait for it to dry, then peel off the tape. I will then use the paint markers to color in the traced images. To do this all, I will use creativity and imagination. I will use my art skills to make the board look presentable.

Who can provide you with effective feedback?

When making something or writing a paper, you usually go and ask one of your buddies to read it over and then you ask them for feedback. When people are bidding, they will be the ones who give me feedback on how to make it better if I do it again. They might say to make the colors brighter, too add more detail, ect.

You Thought This Post Would be Funny? I’m a Frayed Knot

The macrame hanging I plan to make is called The Atlantis Wall hanging. I do not plan to dye it blue, just make so that I can take it home and hang it up. Having just moved here, our house is very bare and this wall hanging will give it a little pizazz. This is what it looks like:

Image result for atlantis wall hanging macrame

The materials used to make this is rope, a wooden stick/rod, and dye if wanted(I would still use blue if I did dye the hanging).

So, as the materials were handed out, I realized the stick was not big enough. Good thing I had I plan B, so I started on a different wall hanging called the Wilma wall hanging. This is what it looks like online:

(I am doing it in white)

It is not too hard to do, but challenging sometimes and so I did it slowly but surely. These are some pictures of me working on it:

 

 

Looking back on this project, I learned how to do macrame. I only did one thing, but the finished project looks nice and complete. This was a great learning experience and I learned something new too. Overall, I will continue to do this in the future and will consider it next year as well.

Skate it up for Happiness

Who is Skateistan? What do they do? Where? Why?

I signed up for a project, Masterpiece With a Message and we a going to paint a skateboard for our project. We are doing this for Skateistan, a company who raises money to buy skateboards and then goes to different places around where kids don’t have many toys and gets them connected to each other with skateboards. They are in Cambodia, Afghanistan, South Africa, and more. They do this so that poor kids are happier all over the world.

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

Some ares of this project that I think will be confusing are that I am not a very great drawer, so my skateboard design might not be as cool as it is in my head. I also think another challenge for me is painting. There might not be all of the colors I want/need and I could smudge my design before it dries all the way. That is something that really worries me.

This is my design of the front of the board

This is what Ii realized plan to do to the skate deck

After a little, I realized that it would be a plain back. So, I added stuff onto my plan.

Project Collisions: Drop 2 Finalle

This is our final design for the 10-meter drop. Our group hopes that it goes well and the force is not over 400

Looking back on Project Collisions, I learned that designing a system of sending drones to people’s homes is not as easy as it seems. For example, when designing a package to hold the object, we had to make sure it was padded, did not fall to fast, and hit the force plate. It was not an easy process. But, I learned how to make a parachute and to secure the object inside of a package. Also, before this project I used to think that using a drone to deliver items to your door was impossible and unheard of. But now I don’t. Now I think that it is a cool idea and it will help preserve the world because less cars will drive around every day, so there will be less pollution. Lastly, looking back on Collisions, I realize that it was a good experience for me and a little bit of a challenge, but that is good for me. For example, I spent time with new people and learned new things. I look forward to the next project and the next opportunity to work together with new people.

Field Study Review

On January 25th, FA decided to go out to the river and stay out there for the whole first block. TERRIBLE IDEA! I was soooooo cold! We were about 10 minutes away from the school, so that was not too bad. We went on this trip because we needed to collect data every few months to see the differences in the temp, bug activity, and fertility.

Samantha and I measuring amount of dissolved oxygen in the river. Cold, but we bundled up well!

 

Data Table

 

In January, the results all said that the amount of DO in water was -0.34%C. We tried getting the DO in three different places to get a variety in different parts of the river. They stayed the same every time. The temperature in the river is 5 degrees celcius. I notice that the data is a little confusing. It might be that we used the computer last time and the LabQuest this time. Next time we go out for a field study, I wonder if the water temperature will be really warm or cold. I also wonder if the amout of DO in the river will go up or down.

Project Collisions: FAILS

Our team constructed the first design using string, white wrapping paper, our package, a small cardboard box, scissors, and tape.  Multiple drops took place and we noticed that the parachute is too small and isn’t working as planned. The force of the drops was still high and the speed is still way to fast for comfort.

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

The parachute did not bring down the force of the drop. The time it took the parachute to fall stayed the same as in Drop 0. The two data tables are shown below.

Drop 0 Data Table:

Mass of Box (g) Force Accuracy Velocity Time (sec)
Drop 0 A 51.6 132.9 Barely on the force plate 12.6 0.3
Drop 0 B 51.6 126.4 Barely on the force plate 10.4 0.3
Drop 0 C 51.6 669.9 On the force plate 10.7 0.3

Drop 1 Data Table:

Mass of Box (g) Force Accuracy Velocity (m/s) Time (sec)
Drop 1 A 51.4 682.8 On Force Plate 10.6 0.3
Drop 1 B 51.4 724.9 On Fore Plate 10.4 0.3
Drop 1 C 51.4 302.8 Barely on Force Plate 10.5 0.3

Some things also went well. Our successes include we have close to perfect accuracy and a reusable parachute that is hard to break.

For our next design, we will improve upon the first prototype by adding a larger parachute to our design to slow the fall even more.

Project Collisions

Blog Post:

In Project Collisions, I am creating a system to deliver mice, computer cases, earbuds, and portable chargers 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 36cm by 26cm was dropped from a height of 5 meters. Below is a photograph of the package:

The package will hold a portable charger for computers. Inside, items are organized like this:

 

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

  1. Plug the force plate wire into the laptop  
  2. Carry bag to recognized drop area  
  3. Use ruler to make sure distance package away from area is correct (40)
  4. Hold the package so that it’s directly above the force plate
  5. Start to record in slow-Mo and regular speed, push play button
  6. Drop package at 5 meters
  7. Record drop data in the data table
  8. Measure distance object bounced from force plate    
  9. Repeat steps 2 to 7 two times through

During the drops, I noticed that the package hits the force plate very hard and then bounces a little. I am a little concerned about the overall well being of the package. This will be fixed as we move through the project. I also wondered if a parachute would help slow down the fall of the package. The following data was collected during the drop:

Drop 0 Data Table:

Mass of Box (g) Force Accuracy Velocity Time (sec)
Drop 0 A 51.6 132.9 On the force plate 12.6 0.3
Drop 0 B 51.6 126.4 On the force plate 10.4 0.3
Drop 0 C 51.6 669.9 On the force plate 10.7 0.3

The average time it took for our package to fall the 5 meters was 0.3 seconds. Not even a full second or half of one!  Then, using LoggerPro, we plotted out the fall of the package.

   

Drop 0 A

Drop 0 B

Drop 0 C                                         

The package fell along the line we plotted, so we were happy, we hope to keep on predicting the fall of the package correctly every time.

A force plate at the bottom of the drop was used to collect data on the impact force of the package. Our group was very succesful at hitting the force plate. Here is a picture below to show:

As a project metric for accuracy, we want our project to keep landing spot on the force plate. If not, only a few centimeters away from it.

The average force on impact was 844.9. As a project metric, our group has decided to ____________________<do what? What is it that the team wants to set as a target for your design. For example, if your  measured force during Drop 0 was 243 N (Newtons) and you want a “soft landing,” what will you have as your initial design target: a 25% reduction? 50%?>.

Summary: Project Metrics

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

  •   Metric 1: Force– the force of drop A and B is around 130 grams, however the force of drop C is around 660 grams. That is a very big difference. So, that makes the average of the three drops 482.6. That s a lot of force. To decrease that big number, our group’s goal for Drop 1 is to reduce 25% of the force.
  •   Metric 2: Time- it took the package 0.3 seconds to fall the last 2 meters all of the three times we dropped it. It is the only constant found in the data table. Anyway, my group and I hope during that Drop 1, it will take the package at least 0.5 seconds to drop the last 2 meters.
  •   Metric 3: Accuracy-  the package fell exactly on the force plate all 3 times. Our group hopes the package will continue hitting the force plate when we do Drop 1. If the package keeps on hitting the force plat as we continue doing drops, it will be one less thing to worry about fixing in the future.

Our group is now building the first prototype. I hope that we find a way to slow the package and keep on hitting the force plate. We also will add some more padding to the package for design one to make sure it is safe during the fall/drops.
