Team,
Here is the way to contact your TED unit installations from off-campus:

http://elabgateway.kamuela.org:8005

this would be cottage 5.
For other cottages, just change the last number to the number of your cottage.

For this week, make sure you understand all of the configuration screens and wizards, as we'll have a quiz at the beginning of class on Wednesday, 10.20.10.

Monday Plan:
Team Ross: Cottage 3
Team Reed: Cottage 1
Team Cook: Cottage 6
Team Monahan: Cottages 7 and 8

We have to get these done in one class, so let's work efficiently folks.

Ok my little piggies,
From now on, before ANYONE leaves class, we are going to have a workspace cleanup check. Today I spent way too much time cleaning up after the soldering gang (low participation points for you guys today), and the router guys.
Let's do better in the future, shall we?
Reminder: Next week Wednesday, your network test corrections are due. As I explained, you are eligible for 1/2 the difference between your score and 100%, so if you had a 60, you could get 20 more points.
Next week:
Meter team moves on to testing with the meters, solar, motors and generators
Soldering team moves on to meters
Router team moves on to soldering.
My plan is for everyone to catch up by next Friday, when we'll have an exam on all three skills: routers, soldering and meters. This test will be open notebooks (not open weblog), so make sure you
1. take notes in your notebook
2. bring your notebook Friday
You should also be copying notes from your notebook into your blog every night, which is what I will grade, along with your class participation.
I hope you are having fun, let's chat next week on our next projects.
Please check here over the weekend for a web assignment.

Team,
Wednesday we'll have a short quiz on gateways, proxy servers, and caching. We'll then break into teams and work on routers and soldering, which should be a blast.
I'll have notes for your teams Wednesday night for the router work.

Greentech quiz
9.13.2010

1 You are working on a client computer that has the wrong DNS entry. Explain how this would appear to the user, and how you would fix it.

The user would not be able to resolve internet addresses, web browsing would be impossible/difficult

2 Another computer has the wrong gateway address. Explain how this would impact the user, including both local and internet traffic.

Only local traffic would function properly

3 A third computer is running very slowly, particularly at login. You restart the mac and do a file system check. Explain how, and what you might see.

fsck -yf, you may see repair notices on the screens

4 After the repair, the machine is faster for apps, but the internet is still sluggish. What network setting do you check, and how do you set it?

order of services, in the system prefs settings under network

5 You are setting up a router/gateway for a friend. She has a cable modem that has the address 66.91.70.75. What address will her laptop inside the network probably have?

192.168.1.x


6 Explain how "fake" networks work, and give an example of several.

192.168.1.x and others allow many machines to share one public IP address. You would do well to look up "public IP address", it is important. Have a look on wikipedia.

7 Is there a method to point incoming traffic for your friend so she can run a web server inside her house? Explain how.

inbound port mapping

8 There was a dramatic attack on the worldwide DNS servers, which almost succeeded. How would this have impacted the internet, and who could still function? Explain.

only folks with cached DNS entries would function, or those with numeric entries.

9 If you had the ability to snoop on a private network, what network settings would you probably use?

192.168.1.x

10 Draw a diagram of a simple network with the internet listed as well as an internal network, with a sample machine on that network

Welcome folks,
Here's what we covered in our first day:
ping
ssh
ping -f
man pages
shutdown -r now

tomorrow, we'll begin with startup repairs, like apple-S
Here's something to play around with if you have time:

If you have a mac, startup the mac (or restart if already on)
When you hear the bong sound, hold apple and s keys
You should see a bunch of white letters on a black background
When the letters stop moving, you should see some sort of name and possibly a # mark
Type
fsck -yf
then return
You should see an online diagnostic begin
When the repairs are complete, type
exit

Give this a try, we'll do this in class Wednesday.

Some articles to read online about command line:

10.4 Server: Enable the Blojsom Admin Console
Thu, Apr 13 2006 at 5:40AM PDT • Contributed by: cheekygeek
OS X Server's Weblog/Podcasting Server (based on Blojsom) is pretty darn cool, but it seems like one should be able to do a lot more from the Admin perspective with one's blog. (For example, deleting a blog category that you previously created). Currently, it appears there is no way to do this -- but there is. It is called the Blojsom Administration Console, and Apple disables it by default, but you can enable it for any blog (on a blog-by-blog basis). Here's how...

To turn on (enable) the Blojsom Administration Console, you just need to uncomment a line in a configuration text file, and then restart Blojsom. First navigate into the proper directory (all of the following is in Terminal):
$ cd /Library/Tomcat/blojsom_root/webapps/ROOT/WEB-INF/username
Replace username with the user's short username. Then open flavor.properties (as root) with your favorite Terminal editor:
$ sudo vi flavor.properties
Once you have it open, remove the hash mark (#) from the front of this line:
#admin=org/blojsom/plugin/admin/templates/admin.vm, text/html;charset=UTF-8
Save changes to the flavor.properties document, and quit the editor.

Restart Blojsom in one of the following ways:
Using Server Admin, under the Web service (Settings), uncheck the Weblogs box and Save. Then re-check the Weblogs box and Save.

From the command line enter:
$ sudo service com.apple.blojsom stop
$ sudo service com.apple.blojsom start
Now if you go to this URL...
http://www.yourserver.com/weblog/username/?flavor=admin
...you will see the Blojsom Admin Console. You will not need to login if you have previously logged into your Weblog (for example, to Add Item). If you see the login screen, then log in!

Under the CATEGORIES tab you will see "Delete an existing blog category." I found one menu item that generated a Tomcat error, but it looks like there are other useful things that you can do here, such as add other users as authors for a blog, etc. Note that the Blojsom Admin Console would have to be enabled on a blog-by-blog basis.

I asked a Blojsom developer at Apple about any negative aspects to enabling the Administration Console and he replied:
There's no particular reason not to enable the Blojsom admin console, although you'll probably find that some functionality doesn't work. We disabled it by default because we don't want to support it.
It may also be worth noting that OS X Server 10.4.6 upgrades Blojsom to version 2.25.

Ok, so what do Mayflowers bring?
-Pilgrims

I'd like to update our class plan for the next six weeks.
Here are some ideas:
1. Each day when you come in, that's worth a point in my gradebook. I'll explain more in class, but it boils down to presence. If you are here, you get a point, if you are not, you are not able to contribute to your team.
2. Progress reports:I'll expect you to present your progress to the group on a weekly basis, at the beginning of each class. I'll also expect this to be online before you give your update, so others can see your progress as well, and build on it.
3. Project work: I'll be working with each of you on your projects, which need to have clearly defined goals and outcomes. This is important, as our evaluation process will be based on this.

Let's discuss in class Wednesday morning, I'm eager to hear your suggestions.

Let me know if you have any questions.

Energy Safari:
Please work with Ms. Lay to label every electrical device in the energy lab with energy consumption in watts. If the device is something that gets hot (like a coffee maker) please make sure the label is somewhere that it won't melt.
How do you measure the power consumed? I've left a stack of power meters in the top drawer on the east side of the main hall.
Some challenges: How do you measure the energy used by the hidden refrigerator? Is it using this power all the time? Perhaps there should be two labels on this one, or even three-think about this.
Another thing: please check the stereos, TVs and all units/tools you use.
Exceptions:
In the monitoring room, you can check all of the machines except the two weather machines and the two servers (brain and network). These are dodgy to get restarted.
Please record your energy safari using the green nano cameras or your laptops, I've left two of the greenies for you, the AP env sci guys should drop off the rest before you have class Tuesday.
I'll be checking in with you guys all week, please update your weblogs each day with videos and email me that you have, so I can give you the points you deserve.
Let me know if I can help in any way, please be nice to Ms. Lay.

Team,
Several of you were gone last week when we covered surveying, so we may spend some time this week on this.
Here are the skills we worked on:

Theodolite/sextant: calculating height with a known baseline
Sample problem: how high is the flagpole, how high is Hualalai, how wide is the football field.

Compass/transit: true north vs. magnetic north, how to adjust for this, using the compass as a triangulation tool
Sample problem: locate yourself on a map, using two visible landmarks, use the compass to determine the width of the football field using two sights from the same point (reverse triangulation).

Surveyor's transit: triangulation to determine distances, using the standard to determine land profiles, 3D graphing using deltagraph.
Sample problem: triangulate to determine the width of the football field, determine a 3D model on deltagraph of the area in front (south) of the flagpole, and west of the flagpole.

Your final will be two-fold: part will be an evaluation of your iWeb portfolio, part will be a written exam with certain skill-set questions. More on this in class. Your iWeb portfolios must contain the following to get a passing project grade:

1. information on the author (you), including your team mates for each project you worked on this semester
2. a semester plan, outlining what you did over the semester, what goals you accomplished, and any tests you think were important
3. a detailed weblog, including background on each video or still photo you include
4. video and still documentation of your projects, including purpose of each video, and your evaluation criteria for each skill-set you were the expert on.
5. a year plan, with the first and second semester outlined, including goals, milestones, deliverables, and evaluation schemes.

See me if you have questions on this.
I'll do my best this week to sit with each of you and complete your evaluations, I think Jordan is next...
See you all in class.

Team,
As you know, your mid quarter grades are due at the end of school tomorrow (Friday 11.6.09).
We'll spend the first part of class going over your mid quarter summation and review.
Here's what I'd like to see in this email, due by the end of the day:

1. What have you done so far this quarter, including your work on the cottages,
2. Your team project, and your qualification tests for your classmates.
3. Links (that I can follow) to your pre lesson videos (these should be different from your how to video), as well as your videos of each person you have instructed.

If you check your online grades (go to physics.hpa.edu) you'll see I've checked out all of your instructional videos-nice work.
You'll also notice that many of you did not turn in your homework assignment on the cottages, or did so late, it's a small thing, but these small things add up.
The biggest hole in everyone's grades are the qualification tests, and it looks like the wood folks have been very busy.
I don't want to get you all into day hall, so let's agree to have at least two of these done by Monday. I'll submit grades based on that.
Your mid quarter report will count as a test as well, which should push most of the posted scores up a bit.

Mid quarter progress reports give you a chance to iron out any missing work before it is too late.

At 11 AM tomorrow, we get to show several board members from the school around the energy lab. I'll discuss this more when we meet, so show up on time, early if you can.

Let me know if you have any questions.

Team,
We meet this week Tuesday, Wednesday (short class) and Friday. Here's the plan:
Tuesday: you should have your pre-teaching video on the server. Here are the steps:
1. take the video, using either the iPods or the laptops
2. open the video in quicktime, select save for web, which will create a folder including an html file. If you are working on a web page for your projects (which I suggest for higher grade), you can copy the text from the windows as indicated. If you want to just leave it as it, email me a link to the html file, which should be inside the folder just created, which will be located inside your Sites folder on the server
3. test your video
4. test your video on a crash test dummy
5. test your video on one of your classmates
Email me a link to your movie before you test it out on helpless victims.

Each of you are capable of making a clear, concise video explaining what your particular skill involves, what you are going to expect from them to qualify, and a set of questions (emailed to you and me before they take the test) as well as a set of questions (emailed as above) after they are schooled by you.

Some notes on your videos:
Christian and Ammar: I know you have been working on GeoCaching. Be sure to include in your how-to video how to use the GPS unit, from turning it on to finding stuff outside. Both of you must work on this. Email me a link to your movie before you test it out on helpless victims.

Michael and Carson: I have a Pelican case filled with HOBO and vernier test units, which I'd like you to include in your video. More on this in class.

Lucas and Grayson: You have so many things to choose from, I'd like you to concentrate on the Phidgets module, how it is used, why it is useful, and a lesson on how to use it.

Nick and Danny: concentrate on your axis camera, including the camera server on the iBoat. I'd like to use your video to send to the folks who supplied the camera server, so they can see how you plan on using it on the iBoat II project. Include screenshots.

Olina, Robbie and Jordan: to keep things safe, I'd suggest doing a video on two things: using the chop saw to create a bench (each "student" can add a piece to the bench) and how to use the router on the edges (which I'll show you Tuesday). I'd stay away from the table saw, as it is the most dangerous piece of student equipment on the campus, by far. Please also make sure you reverse the "groovy table", we'll need smooth tops for our benches. The router is optional, let me know what you think. It makes a hell of a noise, lots of dust, and is dangerous in its own right.

I'd like to begin our qualifications this week, so you can move into your independent projects. Here is a short list of some possible projects you might enjoy:

HEAT team
Infrared camera
wireless networks
surveillance cameras software
control by web interfaces
elab brain
iBoat II: control, video, instrumentation, wireless
network mapping and monitoring
parabolic mirrors
energy monitors
wind turbines
solar thermal project
GIS mapping
GIS integration using JetPhoto
Pumped storage hydro test project
student demos for the lab
netbooks
databases
global footprint project

While you are thinking, check this out:

http://www.thethinkingblog.com/2007/12/diy-wind-generator-for-super-cheap.html

Please also go to this site:
http://physics.hpa.edu/physics/apenvsci/e2_videos/
and look up the design season one, green apple and green for all episodes. Watch these for class discussion. I'll ask you some questions on this in class Wednesday.


Let me know your thoughts. See you Tuesday.

Today, let's meet as small groups after our team summary time.
I'd like to wrap up a set of goals and tasks each of you will have for the others to be qualified in your skillset, then by Friday, I'd like each of your teams to create an online reference, including videos and sample questions for your "students". I'd also like you to setup pre and post questions for each skill.
Finally, about 15 minutes before break, I'd like you to wander up to the cottages to get a reading on the electrical use for your clients. Please email this to me tonight before 9PM for hw credit.
thanks

Team,
We meet twice this week: Tuesday and Thursday for a short visit with your parents.
We have several options on our Thursday session: either show them your videos, or take them up to the cottages to give them a tour. Think about your choice on these.
Here is a problem for you I'd like turned in before class on Thursday:
Go to your cottage and look up the model of the Grundfos pump
Look on the website for the pump, and determine the flow rate for the pump
Measure the tank bottom (cool) temperature to the array, and the array return temperature.
If you know the amount of liters per second of water moved through the panel, and the temperature difference, you can determine the amount of watts (joules per second) collected by the array, as well as how many $ you are saving for each panel.
I'd like to do this before we upgrade the systems, to see a nice before/after report.
Let me know if I can help.

Explain the steps, including what to do and what not to do to complete a copper wire soldering joint, including videos if you can.
Look up a "cold" solder joint, and explain how to detect and avoid this.
Explain why you always do this work in a well ventilated area.

Wire Welding (including MIG):
Explain the process, including videos if you can.
What safety steps did we take? Explain each and why we did them.
Explain why MIG welding is better, and why it is more expensive.
If we wanted to weld aluminum with our gear, what would we need and why?

Copper Pipe sweating:
Explain the process, including cleaning and prep, and why each step is important. You should include videos.
How can you tell if a joint is good or poor quality?
Why do we use MAPP gas instead of just propane?

Posted by: bwiecking

Green folks,
This week, I'd like to take it up a notch with the following:
Welding:
Lets test out MIG welding (metal, inert gas) on clean steel, using the gas tank attached to the welder. The metal will have to be clean, but you might be surprised at how it works.
Copper pipe:
Each of you should be checked out on copper pipes, including cutting, cleaning, flux and soldering.
Copper wires:
Each of you should be able to cut wire, strip the wire, twist, apply flux and solder
Computer skills:
A practical test is in order later this week, probably Friday on computer skills and the other things in your cert book.
Check out the list of leet skills in the entry before this one.
Cat5 cable:
This is important, as we will be creating patch cables and connecting RJ-45 jacks in class. More on this in class.

Green folk,
Please bring a new composition book to class on Friday. We'll glue in your cert cards to the front cover, and I'll collect these for grading after each class.
I'll go over what I expect to be in the book each day on Friday.
Please also make sure your weblog is working, you will be responsible for transcribing what is in your notebook to the weblog each class.
Friday, we'll have an evaluation of your weblogs, so make sure they are up to date, as this will be your second graded work.
Let me know if I can help.

Greentech folk:
This is an outline of skills I hope to help you with by the end of next week. Please see me if you have questions.

Computer work:
Repair work: fsck -yf and appleseed
ssh and remote login to shutdown -r now
startup modes, and what each means:
-S single user mode (what it does, how you can use it)
-C cd mode (when is this handy?)
-T target mode (why?)
-N network mode (why?)
-V verbose mode (why?)

terminal commands:
top
last
kill -9
who
pwd
cd
cd ..
mkdir
cat
more
less
ctrl-z
ctrl-c

network commands:
ping
ping -f
traceroute

Here's what I expect from the first quiz. We may repeat this often to make sure you have what it takes:
1. ping victim machine, copy window, explain results
2. traceroute to external host, same info
3. use top to find process, kill it, show results
4. sudo and ssh to victim machine, shutdown -r now
5. find test.rtf in shared folder, copy contents to email
6. explain who
7. explain last

Here are our teams so far, with their mastery field. They will sign you off for each task. See them for the details of each task.
Robbie/Olina-welding: line, join, cut
Carson/Christian-computer repair skills, network and terminal commands
Jordan/Ammar-soldering copper pipe-clean, solder join, test
Lucas/Nick-cat5 cables-make and test a patch cable
Grayson/Mike-soldering copper wire-strip, join, solder, test

Let me know if you have any questions, these skills should be completed and signed in your cert sheet by the end of next week.

Great to see the energy lab with you folks today.
Thanks also for your help with the lumber-how would you like to make picnic benches for the pavillion area? A thought.
We'll be getting into more fun next week:
Rob and Olina will check everyone out on welding, which will be one check out in your cert book.
Carson and Christian will check you out on computer skeelz.
Jordan and Ammar will be the gurus on soldering copper pipe
Lucas and Nick will school all of us on Cat5 patch cables
Grayson and Mike will rule wire soldering.

As we move into these, I'll be grading you on your cert tests, demonstrations I ask of you, and videos you put on your blog. More on this next week.

The best thing you can do for now is to go to your weblog, and write down anything and everything you think might help you on a test:
These can be computer commands, welding tips (no pun intended), cat5 cabling codes, you name it.

This way, I can keep track of your progress and keep our gradebook up to date.

Loads of fun next week, think of what you'd like to create in our next phase.
Remember: each project and skill you learn will be crucial in setting up the lab, the demonstrations and projects we have there, and should involve collecting energy or demonstrating renewable/sustainable practices for third world folks.

Send me your ideas, I'm really interested in what you think.

Explain the process to do a file system check and repair on a mac, from startup to startup.

Explain the process of sending a message on the internet, using analogies if you like.

Explain "target mode" and why you might use it for the light and dark side of the force...

Are you having fun yet? What would you like to do next?

email me your answers at bill@hpa.edu with the subject line: quiz
