    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>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><a moz-do-not-send="true"
          href="http://www.reducativa.com/xo/man-sis-sensoresdetemperatura.pdf">http://www.reducativa.com/xo/man-sis-sensoresdetemperatura.pdf</a></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><span class="Apple-style-span" style="font-family:Arial"><a
            moz-do-not-send="true"
            href="http://youtu.be/yZkz_a52I6s?t=1m18s">http://youtu.be/yZkz_a52I6s?t=1m18s</a></span></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>
