Spring 2017 – Final Project

Final Project

Over the next six weeks, you are tasked with developing a project that will address some aspect of Computer Science. The project must include an experimental element and a written description that combine to answer a guiding question.

 Guiding Question:

You must formulate a driving question that will guide the development of your final product. This should not be a question you already know the answer to, although you should form a hypothesis that will guide your testing. Nor should it be a question that has an answer that can be looked up on Google. Your driving question should be a computer science-related question that can be answered through experimentation and proven with empirical data. Possible driving questions include (but are not limited to):

  • How difficult is it to write a computer program that can guess a password?
  • How can one design a video game that teaches someone how to do something?
  • How can one learn more about app design by creating a new app or making improvements to an old one?
  • How does a computer work, and how are all the parts connected together to create a working electronic device?
  • Do extreme temperatures (both hot and cold) affect how well a computer performs given tasks?

You will need to submit your guiding question to Mr. Marmolejo, and receive approval before the end of the week. Upload a Google Doc with your Guiding Question to today’s Google Classroom post by end of day on Friday, March 24th.

Product:

At the end of the project, you will need to have a way to demonstrate the results of your experimentation. There are 3 products to choose from, each with varying levels of difficulty. The harder the product is to create, the more points it is worth.

Option 1 – 100 points: Create a working model of your project using your own materials, or materials that are available in the Center for Computer Studies, along with a written report detailing the steps you followed to complete the project, your experimentation procedure and the results of your experiment that lead to the answer you determined for your guiding question.

Option 2 – 85 points: Create a PowerPoint presentation that discusses all the elements of your experiment and details the steps you followed to complete the project, your experimentation procedure and the results of your experiment that lead to the answer you determined for your guiding question.

Option 3 – 70 points: Create a poster that discusses all the elements of your experiment and details the steps you followed to complete the project, your experimentation procedure and the results of your experiment that lead to the answer you determined for your guiding question.

Remember, these products need to include both the visual and written elements to receive full credit.

You will have checkpoints along the way and will get feedback from Mister Marmolejo throughout the course of the project.

Do’s and Don’ts:

Do be sure to pick a project that you are interested in, and that will continue to hold your interest for the next six weeks.

Do your research in class, and your experiments if possible.

Do yourself a favor and write up a plan for the next six weeks.

Do use your class time wisely: to conduct research, to build your project or to write up the results.

Don’t pick a project that will take one day to finish and expect to chill for the next five and a half weeks.

Don’t build a project for its own sake – make sure you develop a guiding question and an experimental procedure that the project can address.

Don’t sit at your desk and watch YouTube videos, unless they are directly related to your project.

Don’t bite off more than you can chew: make sure your project is something that you can finish within six weeks.

Don’t assume that six weeks is all the time in the world. As you discovered in the Directional Antennas project, the next six weeks will go much faster than you think – plan and manage your time accordingly.

Week 1 – Checkpoint

As soon as possible, you should upload a Google Doc  to today’s Google Classroom post that contains the following details:

  • Your Name (if you are teaming up with someone, include both team members’ names)
  • Your guiding question
  • If you are teaming up with someone, you must submit a Team Agreement as well (edit the PDF document in Acrobat and upload a digital copy to the Google Classroom assignment post).

Team Agreement 2017

I will review your guiding question and return your document to you with my approval, or with suggestions for revision. If your question is approved, you may proceed to the planning phase of the project. If your question needs revisions, submit the revisions for my approval as soon as possible.

Your guiding question must be approved by the end of the day on Friday, March 24th, 2017 for you to receive credit for the first checkpoint.

DIY Directional Antennas – Final Reflection

Objective:

I can complete my midterm assessment by demonstrating and evaluating what I learned during the DIY Directional Antennas Project.

Links:

DIY Antennas Project Final Reflection Form:

Google Classroom

Topics Discussed:

Wireless Networking
802.11 Wi-Fi spec
Directional Antennas
Waveguide Antenna
Yagi Antenna
Flickenger design Antenna

Assignment:

Today, we will complete our directional antenna project. Our goal was to sustain a 2.4 GHz Wi-Fi signal over a minimum distance of 100 yards (300 ft or ~92m). Many of the antenna designs successfully completed this task, but only one came out on top with a whopping -68db signal and 32% sustained signal quality over a distance of 150 yards. Please congratulate Luis and Eli for their outstanding helical antenna design that conquered all other designs. They will be enjoying pizza and wings on Friday as the rest of the class completes the final reflection assignment.

The link for the reflection assignment can be found here. Please follow the instructions on the form, and answer each question group with a complete five-sentence paragraph. Pay attention to your spelling, punctuation and grammar as you compose your paragraphs. This assignment is to be written in a professional tone in an academic voice, and it will be graded based on the criteria described on the form. Each team member must submit their own form, but can work together on the wording of the individual submissions. This assignment is effectively your final project assessment which represents the major portion of your project grade, and should be addressed accordingly.

Good luck, and thank you for all your hard work on this project. Do your best on your reflection and then it’s back to the lab for some Linux installation and configuration exercises!

Directional Antennas
Waveguide Antenna
Yagi Antenna
Flickenger design Antenna

Assignment:

Today, we will begin the final revision phase of our directional antenna project. Last week, two teams tied with equivalent dB gain readings on our test receiver router, but only one can win! Remember that the goal is to sustain a 2.4 GHz Wi-Fi signal over a minimum distance of 100 yards (300 ft or ~92m) and the winner will be the one who sustains the highest (negative) dB reading and signal quality over the longest distance.

We will conduct final tests the week of February 21st (Monday the 20th is a holiday!). To be considered a success (and receive credit for the project), your antenna design must be able to sustain at least a one-bar wireless signal over a 100 yard distance (the length of the football field). If your team is not present for the final test or you do not have a working antenna to test on Tuesday, February 21st, you will receive a zero on the second half of this project without the opportunity for make-up. (We’re only going out to the field once.)

Reminder: The team (or individual) that produces the antenna that can reliably sustain the highest gain signal over the longest distance will receive a personal pizza and wings party, to be held while everyone else writes a four paragraph personal reflection describing their participation in this project.

Good luck, and remember: Your antenna doesn’t have to be perfect, it just has to be better than everyone else’s.

Assignment:

Today, we will continue the build phase of our directional antenna project. Remember that the goal is to sustain a 2.4 GHz Wi-Fi signal over a minimum distance of 100 yards (300 ft or ~92m).

All tools and equipment are on the metal cart Room 212. The wireless network cards are located in the cabinet closest to the Teacher Workroom door in Room 212. If the cabinet is locked, see Mr. Herrera for the key. The transmitter testing cart is in the back of Room 225, and the username and password is on a stickynote at the bottom of the screen. The receiver cart (with the target router) is there as well, but will need a magnet instructor to log in with the admin password.

Please use this time to make progress on your project. On Friday, February 10th, we will go out to the football field and test all completed antennas to allow those with working products to see the results and modify their designs if necessary. You should have a finished antenna prepared to test at that time so you can tweak the design if necessary before the final test on the week of the 20th!

We will conduct final tests during the week of March 20th. To be considered a success (and receive credit for the project), your antenna design must be able to sustain at least a one-bar wireless signal over a 100 yard distance (the length of the football field).

Reminder: The team (or individual) that produces the antenna that can reliably sustain the highest gain signal over the longest distance will receive a personal pizza and wings party, to be held while everyone else writes a four paragraph personal reflection describing their participation in this project.
