Weekly Blog : Victor Nguyen 7A Design Process I have finished many steps of the design process. I would say I finish the Communicate Final Design, because we have finished the trifold, for our project.  Summary This week we did some things to get our charity fair project done. In this class, Elective, we are supposed to do the charity fair poster. My group is me, Pierson and Ian. For the first few class periods, we were given a trifold. So we went to Ms. Link's room to get 1.5 meters of paper to cover up the trifold. We saw that there was nothing on the trifold, so finished up the math parts, instructable, title, info about our charity. On Wednesday, we printed out the things that we need on the trifold. On Thursday, we glued everything onto the trifold. It looked nice, we had the math parts on one side, the instructable on the other, and the image and title in the middle. As you can see, we did somethings to get our charity fair project done. Image/Links This is ...

Sound Amplification Project Blog : Victor Nguyen 7A Image/Links: Our finished device Link to Manual:  https://docs.google.com/a/oakgrovesd.net/document/d/1ExTEDaXqIdBsOPZ7hHIS_zR0nLNrBYs_zjVFvatH8qc/edit?usp=sharing Summary At the beginning of the project, we assigned/chose our groups, which is me, Pierson, Abram, and Ben. Our task was to create a device that was portable and could amplify sound, in a room or party. In order to create a prototype, you need to have multiple ideas, just in case. We learned having many ideas was a good thing, because sometime you could be wrong and have more to come. Everything in the middle was the same, because we had to build a prototype. But after we tested, we learned that holes needed to covered up to prevent any loose sound from coming out.  Near the end, we had to make an ignite presentation. We learned that we had to do a maximum of 15 slides and have it advance every 15 seconds, which will be under 2 minutes. Instead,...

Weekly Blog : Victor Nguyen 7A Design Process I have finished many of the steps, from Designing the Problem to Make and Test a Model. In those steps, we made sketches, design solutions, and started to create a prototype, of our amplifier. Now, since we know, we are starting to go on the step, Modify and Improve Design , which we are working to redesign our device. Summary This week we are continuing to work on the project, called  Sound Amplification . On Monday, everybody, including our group that include me, Pierson, Abram, and Ben, have continued to create our prototype. We have realized that we had holes, that would let out some sound when we project it, so we had to patch up as much holes as possible using hot glue. The next day was testing day. Everyone tested their prototype; because we patched up the holes, it turns out that our group had a device that amplified and increased the most decibels. On Wednesday, we were finding a way to redesig...

Weekly Blog : Victor Nguyen 7A Design Process I  am on the step ' Background Research ' of the Define the Problem  step, and about to finish. In this step, I did some research about science of sound. I am about to finish background research science of amplification technology. After I'm finished, my next step is brainstorm. Summary This week we have started a new project, called Sound Amplification . At the beginning, we were assigned/moved seats, for new groups. My group is me, Ben, Abram, and Pierson. Mrs. Garcia introduced a new site, called Trello , which helps keep us organized with our work. It tells when things due, what things we have done, and what we need to do still. So, the first part of this project is background research. Our group had to do some research about Science of Sound and Science of Amplification of Technology. This all will help us learn more about, and help us with our presentation at the end. We have all documented our notes onto another ...

Reverse Engineering Project Blog : Victor Nguyen Image This is invisible ink. We used OUR flashlight, with homemade UV. It works. Summary As Mrs. Garcia had said, this project has been taking a while, and is getting boring. At the beginning of this project, my group was Abram, Frank, and Pierson. We chose the reverse engineer the flashlight, because it was simple. The steps of this project is, Proposal, Manual, Make It Better, Put It All Together, and presenting. When we were working on our proposal, we just hypothesized of how much it cost, did some light measurements of the flashlight, and said why we chose this item. In the manual, we actually did everything in depth, such as measurements, cost, and explanation. We decided to make it better, by making it UV. Before this, we even decided to present this for Student Exhibition Night, to appreciate Mrs. Garcia. But sooner later, we took too long on this project. Our group didn't mind, because it was a good project s...

Weekly Blog : Victor Nguyen 7A Design Process I have just finished the 'fix problems' of the 'Modify and Improve Design' step. Now I am on the next step, which is the  'improve design' step. Summary This week, I tried to juggle different projects. The projects and assignments I was working on was the Reverse Engineering and the Simply Machines Project. On Monday, with the help of Frank, Pierson, and Abram, we turned in our manual of the flashlight. Then, the next 2 class periods, we did some finishing touches of the Simply Machines project. My project was the Automatic Fish Feeder. At a set time, a wire sets off the feeder to start. A trap is there to stop from too much food going out. Once I was done, I turned it in. Later Wednesday, it was Exhibition Night. My group presented our Flashlight Manual. Many people liked it. The next day, we tried to add some more changes, like turn the flashlight into a UV light, and it worked. This week, was a pretty...

Weekly Blog 4: Victor Nguyen 7A Design Process I have just finished the 'Brainstorm' in the Generating Possible Solutions. Now, we are 'Thumbnail Sketching' step.  Summary This week, we have done some things, probably the same as last week. Well on Monday, we had got started on our new project, Reverse Engineering. We chose our groups, its Abram, Frank, Pierson, and I. Then, we need to choose our item. We didn't really take long, so we simply decided, the Flashlight. The first step of the Reverse Engineering is our proposal, so started to write it. The proposal is down below. On Thursday, Mrs. Garcia wasn't here, so we had to watch a video and answer some questions. And now, it's Friday and it's Blog Day!!! Image Reverse Engineering Proposal
