I must have missed it if there was any comment on it, but Claudia
Urrea has been working on sensors for many years already - <br>
She was kind enough to show me a box with several ready to use
sensors the time I was in OLPC headquarters in Boston, like 3 years
ago? <br>
<br>
As the head of the education dept of OLPC (unsure if that is still
the case or the actual title) no doubt she can contribute detailed
and proven lesson plans that teachers have used successfully, full
reports on the use of sensors, in the field, in OLPC deployments.<br>

<div><br>
</div>
<div>Looking forward to being in SF! I'm not ready to sit down for
a sensor session, but here's a historical bit...</div>
<div><br>
</div>
<div>I found one of XOExplosion.com's temperature sensor kits from
2008 and just posted photos and their parts list to Flickr:</div>
<div><br>

<div><br>
</div>
<div>Plan Ceibal's handout is a nice update of the wiki page:</div>

<div><br>
</div>
<div>I'll bring the kit. It looks like an assortment of heat
shrink tubing is needed along with basic soldering supplies. I
typically use a heat gun on shrink tubing, but a BIC lighter is
quick and easy. You might want to check with Sameer if it's OK
to use one of those. I think this video by Becky Stern of
Adafruit demonstrates soldering in a snappy way:</div>

<div><br>
</div>
<div>Looking at some of the sensor documentation for Turtle Art,
it looks like the use of a thermistor with two leads simplifies
the assembly a bit, but the addition of a resistor or zener
diode are suggested for XO-1.5 and XO-1.75.</div>
<div><br>
</div>
<div>Guzman's video of temperature graphing in Turtle Art is
awesome. Are these project files available anywhere? Looking at
his video surfaces the fact that there's much more to the sensor
exercise than just soldering:</div>
<div><br>
</div>
<div>- Source parts and assemble the desired sensor</div>
<div>- Test (and calibrate?) with the particular model of XO</div>
<div>- Test with a specific project file for Turtle Art w/sensors,
Scratch w/sensors, Physical Etoys, etc. </div>
<div>- Create updated documentation and devise lesson plan ideas</div>
<div><br>
</div>
<div>I messed around with the temperature sensor briefly back in
the simpler times of 2008. Now the solution matrix has grown
quite a bit.</div>

<div>I hope to be going to Haiti next March and plan to
bring some lessons and an "engineering challenge" around
the kids/adults building Solar Stills. So temperature
and humidity sensors would be good. I would also be
interested in ones we can hook in through an arduino
(like the versions C. Scott Ananian designed) for data
collection.

<p
style="font-size:12px;font-family:Helvetica">Hi
Folks, It's crunch time!</p>
<p
style="font-size:12px;font-family:Helvetica"><br>
</p>
<p
style="font-size:12px;font-family:Helvetica">STEM,
SET, SCIB... no matter what you call it,
the world is focusing more and more on
science and technology in education. The
XO is an ideal platform for furthering
science education through hands-on
student based experiments that will
teach and/or reinforce science concepts
from core curriculums. It is a perfect
use of the XO for any deployment.</p>
<p
style="font-size:12px;font-family:Helvetica;min-height:14px"><br>
</p>
<p
style="font-size:12px;font-family:Helvetica">So
far the following people have shown
interest in doing something with sensors
at the SF Summit and/or Sugar Camp.</p>
<p
style="font-size:12px;font-family:Helvetica;min-height:14px"><br>
</p>
<p
style="font-size:12px;font-family:Helvetica">Tony
Anderson, Janissa Balcomb, Ed Bigenho,
and myself. Also, it is possible Nick
Doiron and/or Alex Kleider can help us
with the building.</p>
<p
style="font-size:12px;font-family:Helvetica;min-height:14px"><br>
</p>
<p
style="font-size:12px;font-family:Helvetica">Surely
there must be more of you that are
interested in this!</p>
<p
style="font-size:12px;font-family:Helvetica;min-height:14px"><br>
</p>
<p
style="font-size:12px;font-family:Helvetica">The
plan is to make the sensors early on,
maybe in free time, maybe at the
Noisebridge makerspace, maybe at the
Summit itself. That way, folks who
aren't staying over for Sugar Camp will
have the sensors to take home with
them. Those people who are able to stay
past Sunday will have a chance to
experiment with the sensors and find
ways to use them in science lessons,
probably focusing on upper elementary to
middle school science. These ideas will
be shared with all who are interested,
principally on the SugarLabs wiki.</p>
<p
style="font-size:12px;font-family:Helvetica;min-height:14px"><br>
</p>
<p
style="font-size:12px;font-family:Helvetica">Sensors
we will probably build will include
temperature, light, and possibly one or
two others. Once we know how to build
and use them, it should be fairly easy
to transfer what we learn to building
others once we are home.</p>
<p
style="font-size:12px;font-family:Helvetica;min-height:14px"><br>
</p>
<p
style="font-size:12px;font-family:Helvetica">If
you want to be a part of this, I need to
know in time to get the supplies for
you. I plan to make a trip to a large
electronics store in the San Fernando
Valley next week to purchase the parts
we will need. Their prices are excellent
and they will sell small quantities if
needed. My best guess is that most
sensors can be made for $5 or less…
maybe much less. That means your
investment for one each of 4 different
sensors would be $20 or less.</p>
<p
style="font-size:12px;font-family:Helvetica;min-height:14px"><br>
</p>
<p
style="font-size:12px;font-family:Helvetica">So…
what I need to know is…</p>

<p

you want to be included in this project?</p>
<p

</p>
<p
style="font-size:12px;font-family:Helvetica">If
yes, <i>what days/dates </i> will you
be in SF and what part of town are you
staying in?</p>
<p
style="font-size:12px;font-family:Helvetica;min-height:14px"><br>
</p>
<p
style="font-size:12px;font-family:Helvetica">What
sensors besides light and temperature
are you interested in building?***</p>
<p
style="font-size:12px;font-family:Helvetica;min-height:14px"><br>
</p>
<p
style="font-size:12px;font-family:Helvetica">Ideally,
how many sets of parts for each sensor
would you like me to get for you? I
don't have an endless pot of money and
expect to be reimbursed, but I can
probably put enough into this for
everyone interested to have at least one
of each, maybe more.</p>
<p
style="font-size:12px;font-family:Helvetica;min-height:14px"><br>
</p>
<p
style="font-size:12px;font-family:Helvetica">I
will be making my shopping list for this
over the weekend, so don't delay in
making up your mind!! Just send me a
reply to this email with your
"reservation" and info.</p>
<p
style="font-size:12px;font-family:Helvetica;min-height:14px"><br>

<p

If you missed or misplaced the links to
into about sensors, here is a list from
the SugarLabs wiki and a link to a
series of videos make by Trinidad Guzman
who makes and uses a lot of sensors with
his students in Uruguay. The narration
is in Spanish, but if you know any
science no language is needed!</p>
