Arduino

We're going to get going with some Arduino Projects in our Principles of Engineering Courses (2nd and 4th Period) and in our Engineering Projects Class (3rd Period). I had ordered a batch for the students that had chipped in on the Engineering Fund. If you didn't contribute, and would like to get some hardware for yourself, here are some links to the products on Amazon:

The Arduino Uno on Amazon. When I posted this, the board was listed at $20, a very competitive price (The best price I could find when I ordered them for the class was closer to $30 :( )

The Uno Starter Pack on Amazon. This kit provides some basic goodies to get going with Arduino projects.

A USB A to B Cable is needed to interface the Arduino with a computer (Mac or PC). Programing is done in the Arduino Integrated Development Environment (free to download at Arduino.cc). An A to B USB cable is the type of cable that is typically used to connect a printer to a computer. You may be able to use an existing/left over one so only order if you do not have something on hand that is usable.


Optional Texts:
There is a plethora of information on Arduino on the web. If you prefer having a physical reference, here are a few to consider.

We have one or two copies of this in class. You may like to have your own:
Getting Started with Arduino

This book appears similar to Getting Started with Arduino but focusses on the programming aspect of the process:
Programming Arduino

Making Things Talk (as in electronic communications between objects) is an incredible text that a person could make a full college course out of. We will attempt a few of the projects in this book. At $20, this is an incredible value (even more so compared to the $100+ that you'll be paying for texts in college).

"Asking the Right Questions": The Cornerstone of Problem Solving

The goal of the Engineering Projects class (3rd Period) is to give our students the experience and tools for a great start on the path of technical leadership.

For the 2nd Semester, students will team up and select a topic to present on that will help us all gain insight on how to attack problems worth solving.

Here are the slides from our discussion this morning. If you're looking for a good read over break, consider one of the books listed below. The core concepts of these books will help improve your understanding of how to choose problems worth tackling and techniques you can use to enhance direction, alignment and commitment from those you collaborate with:

Tiki Smasher!!!

Marco and Hunter have been putting together a little game in our Engineering Projects class.

"Tiki Smasher"! Coming soon to a smart phone near you...

"I Love It When A Plan Comes Together"...

... well, we hope this one comes together!

4th Period reminded me there was a Holiday Door Decoration contest and was enthusiastic to participate. So we took today to brainstorm/prototype some engineering based decoration solutions.

Having an impromptu contest pop up is the perfect way to engage our Creative Problem Solving minds and it was neat to see how effective the class was at developing concepts and informally collaborating:





The proof is in the pudding however so we'll see if we're able to get something organized. Judging is after lunch tomorrow so we don't have a lot of time!

Contests/Problems seem to bring the best out of our teams. My goal is to have all of our efforts revolve around team based problems/challenges and I am working to that end.

6th Period Puzzle Cubes in Progress

How Many Pieces are Possible?

We've had some great debates about how many puzzle pieces you can make with 5 cubes.

Here is one students start at a list of possible parts using 3, 4, 5 and 6 cubes. These are very nicely drawn (please use this as a standard to achieve in your part drawings):



I found the following list of solutions online. How many combinations are there with 5 cubes?

? - What math can we use to predict how many possible part combinations there are?
? - Do all of these parts meet our design criteria/constraints?

Puzzle Cube Challenge

Renewable Insulation Challenge!

The largest amount of energy consumed within the average home is related to maintaining adequate climate control through heating and cooling systems. To conserve energy and decrease expenses associated with climate control, proper home insulation techniques are required. Insulation technologies relating to materials and application have advanced throughout the home building industry with time. The home building industry once relied on straw and newspaper for insulating material. The industry currently utilizes technology such as fiberglass and blown expandable foam. Insulation material advancement is driven by consumers demanding insulation material designed for high insulation value along with positive occupant health and environmental impact. Many homeowners today are designing new “green” homes. To meet the needs of green consumers, insulation manufacturers are developing insulating materials made from recycled products such as jeans, t-shirts, and other low volatile organic products that can be treated with boric acid. Manufacturers have found that going green has other benefits to the homeowner as well, such as cotton’s ability to provide excellent soundproofing.





Criteria:
• Design a renewable composite insulation material.
• Achieve the highest R value in the class with your design.



Design Constraints:
• Composite insulation material must have overall uniform thickness less than or equal to one inch.
• Composite insulation material must have consistent internal composition.
• Individual insulation material(s) must be environmentally friendly.
• Individual insulation material(s) must be recyclable.
• Individual insulation material(s) must be economical.
• Composite insulation material dimensions must not exceed the overall dimensions of Heat box apparatus top.



Measurements and Calculations
See class handout


Conclusion Questions

1. Explain how your house might lose energy through radiation.



2. What modifications could be made to your team’s insulation design that allow for more energy efficiency?



3. Which beverage would be more beneficial for cooling you on a hot summer day – a cup of ice cold water or a cup of hot cocoa? Justify your choice.



4. How do birds insulate their bodies to prevent energy loss on the skin’s surface?

Binary Counting

This is a neat video that Dan shared with me. Digital data ultimately is a series of 1s and 0s. We had talked about this in a few of our classes and this video can help you visualize a counting system based on switches:

Nice Guys Finish First

Congratulations to our Boys Water Polo team for seizing the CIF championships this evening. It was a nail biter of a game! Two periods of overtime followed by a round of sudden death. Good thing we have the week off 'cause I'm too hoarse from yelling to want to do much talking on Monday.

Special congratulations to all of our Engineering Water Polo contingent, in particular Nick, Joe and John.

This game was fun for me to watch. It was hosted at my old stomping grounds, LJHS. I got to watch the game with Dr. Petterson, my childhood buddy who played varsity goalie all four years of our high school era. He really knows his stuff and it was like having my own personal commentator to point out all the intricacies of this gripping match. I learned a lot.

The Bishops and Islanders teams line up to start the game:


Story is the split between expecation and outcome. The Islanders set us up for a great story this evening by letting Bishops take an early lead of 0-3. It was looking grim for some time.

The game was tied up by the fourth quarter and after two periods of overtime, the score was tied up yet again. The game progressed into a final Sudden Death:


Amazing! The Islander's score in sudden death to clench the title!:


How many people can you count in the pool? Yes, that's more than both the teams... extatic Islanders were jumping in from the stands! What an exciting game.

Lego Time!

We had some quality building going on today. Here are some of the guys from 6th Period hard at work:


Each student selected 25-30 pieces in turn from the available pool of parts. This meant it was more challenging to come up with a compelling design. Never the less, everyone seemed to create something interesting.

Will made an awesome chicken!:


Lexi made this neat tree that looks straight out of an 8 bit video game:


It's not easy making something from scratch. Nice job today 5th and 6th periods.

Lego Dims

These Lego dimensions will be helpful for a project we start after Thanksgiving (assuming the District gets our Inventor licenses sorted out!).

What is this below and what might we be doing with them?...

"Cooperate and Graduate"

We've been spending a lot of time in our Engineering Design sections working on team based technical drawing quizes. Learning to work with colleagues is an important career skill. Here's a clip from tonight's 60 minutes that backs me up.





This is a CBS/60 Minutes video so please excuse any advertisements the player forces you to watch...

Service

It was thoughtful of the PTO to leave a nice Veteran's Day note for me at yesterday's luncheon they put on for all the CHS teachers. Thank you for the thought and also for the excellent food (apparently catered by Sapori if anyone has the chance to eat there).



It is the spirit of service, and the goal of spreading a design thinking mindset, that has me excited about the courses I'm developing to encourage leadership and innovation. I gained great experience as a servant leader in the Army and am happy to have a chance to put these skills to good use again. With any of my efforts teaching, I have the student's best interests at heart.

I had some amazing adventures when I was in the Army 10+ years ago. Here are a few pictures from that era:

Despite being an Infantry Officer, I spent *a lot* of time maneuvering combined arms armored units (Tanks + APCs). Don't let the smile fool you, a few days in the snow in a metal box gets cold fast (although I did love this work!)...

3rd Period - I'm Out Today!

Hi 3rd Period,

It looks like I'm going to miss our class as well today. Dane's Nanny called in sick this morning so I'm stuck at home! I love my time with Dane but I wasn't expecting this change of plan today.

Please continue working today on the Scrum tasks you've comitted to.

We will have a scrum meeting on Thursday and review:

1) What you've done
2) What you plan on doing
3) Any roadblocks you've encountered

Thanks,

Mr. Olson

2nd Period - Tasks While I'm Out!

Dear 2nd Period,

I'm attending the School District's strategic planning meeting this morning. Please work on the following in the listed priority. I expect you all will complete #1 (The Deep Dive). Any extra time after that is a chance to get going on #2. #3 is very good so take a look at that if you have time.

Thanks!

Mr. Olson


1) Watch and complete The Deep Dive, an introduction to "Design Thinking" (this may be familiar to a few of you!)
2) Review and begin thinking about who you'd like to talk to for your Professional Interview assignment.
3) Steve Jobs' Stanford Comencement Speech

Happy Halloween!

We're going to make virtual pumpkins in class today... how awesome of a pumkin can you make?

Post your pumpkin to your blog to show us what you can do (choose export>image from the Inventor menu to save a screen shot of your work. Then post the image to your blog):

7 Billion Chances to Make a Difference!

It's theorized that the human population reached 7 Billion today. That's a lot of opportunties to design/build solutions to problems.

? - As you move forward in your life, what are some of the challenges listed in the following video that you could participate in solving?



a

? - 7 Billion is a huge number. How can we conceptualize that many people? How many people live in San Diego? How many San Diegos is 7 Billion?

Go Islanders!

Energy Sources!

Image from classroom-energy.org
Americans spend 500 billion dollars each year on energy. As populations and appetites increase, the world faces a challenge of significantly growing energy needs. Many unique energy sources are available. To meet future energy needs, engineers need to design technology to contribute new ways to harness energy, increase efficiency, and better transport and store energy.


Objective:
Your task as a class is to prepare a presentation on the different energy sources we use collectively as a society (9 types from the graphic above). The class must cover each of the sources listed.

Presentation Grading (4 pts)
The presentation is worth 4 points. The content and presentation standards will be selected and agreed upon by each class period (listed below). Half your score will be based on how well you as an individual address the agreed upon content and presentation standards. The other half of the score will be earned by the class collecitvely.

2nd Period Considerations:
Content:
• Energy Source - Overview, Steps for Harnessing Energy, Major Energy Uses
• Consideration of Efficiency/Conservation
• Costs - Setup, Consumer Costs
Process:
• Unified look/theme to entire presentation
• Reduced Text - Use bullets and talk to them
• Effective Images - do they tell a story?


4th Period Considerations:
Content:
• Uses
• Effect
• Pros/Cons
• Effiecy
• New Developments
Process:
• Unified Theme
• Bullet Points - "Speak to the bullet points"/"Write less, talk more"
• High Value Images - Do your images tell a "Story"?

Other Considerations (Your period may not have selected these as relevant for the presentation but please consider them anyways):
• Is the energy source classified as nonrenewable, renewable, or inexhaustible?
• What are the infrastructure requirements for utilizing this energy source?
• What emerging technologies will make this energy source safer, more usable, more efficient, cleaner, etc?

Blog Post Grading (2pts)
Post the images of your section of the "Energy Sources!" Presentation to your Blog. Copy and paste the following questions into your post after your slides and answer them.

1. Describe one thing that surprised you about the energy source that you researched and presented.



2. Describe one thing that surprised you about an energy source that another team presented.



3. Describe and defend what you believe to be the most important technological need regarding energy.

The Needs of the Customer

As Engineers and Designers, we create solutions to meet the needs of people and solve problems.

? - How does the revolution in Libya and the capture/execution of Gaddafi reflect poor design thinking on Gaddafi's part? Are there other places in the world that are facing challenges related to a lack of human centered design?

Recursion

Iterative design is a cornerstone of the Creative Problem Solver experience. Here's a nifty video that displays the connection between iteration/recursion and the Madelbrot Fractal:




Recursion within this human constructed fractal is interesting to us because:

"Approximate fractals are easily found in nature. These objects display self-similar structure over an extended, but finite, scale range. Examples include clouds, river networks, fault lines, mountain ranges, craters,[8] snow flakes,[9] crystals,[10] lightning, cauliflower or broccoli, and systems of blood vessels and pulmonary vessels, and ocean waves" - Excerpted from Wikipedia

The idea that recursive structures occur naturally adds weight to the idea of using an iterative process in design and problem solving.

? - What is effective about this presentation in regards to visualizing the data?
? - If our goal is to improve the process, how is this visualization helpful?
? - What's missing/how would you improve the utility of this visualization?
? - What visualization have you come up with?

I *Heart* the 80's!

It's "80's day" today at CHS...

There was a lot of memorable music from the era. I know that's a little before your time but do you have a favorite band or album from the period?

Here's a selection of classic 80's music to get the day going with:

$150 of Duct Tape

This was a killer price for this much Duct Tape (about half of what it would be anywhere else):

(A very helpful Costcoer that saved the day for the 2nd Annual CHS Cardboard Canoe Challenge)

I had been to the Costco on Morena with no luck on finding tape. I followed up at the Business Costco in Kearny Mesa to find this good price. It's important to me to be a good steward of our Engineering Lab Donation fund.

I nearly missed the tape in the Kearny Mesa store and have a good story regarding the importance of communication and an outgoing demeanor for anyone that's interested in hearing it.

? - Why is Duct Tape called "Duct Tape"? What is the purpose for which the tape is named?
