What would be really nice is a compact document that I could include
in the Measure activity itself...

Hi Folks,
I thought it would be a good idea to take a few minutes out to recap what we
did in the Sensor Workshop on the first day of Sugar Camp in San Francisco.
It was a good way for the non-programmers at the SF Community Summit to have
a reason to stay over for Sugar Camp and have a chance to relax, visit, and
get to know each other a little better while learning more about things that
you can do with XOs.
We had about a dozen folks interested in making sensors so we pushed tables
together so we could work collaboratively. Everyone had a bag of parts and
materials to make 3 types of sensors: a light sensor, a temperature sensor,
that needs to draw power from the XO via a usb cable, and a generic sensor
cable with alligator clips that can be used for a variety of things.
We began with the light sensor, and by lunch time almost everyone had a
working model and was testing it with the Measure Activity on their XOs. We
tried a variety of solutions for putting them together, and, in a few days,
I'll put some of them on one of the wikis along with parts lists, sources
for parts, and basic instructions. If you have more photos of our project...
send them to me in an email and I'll add them to the wiki.
To solder or not to solder was the big question of the day. Ed Bigenho was
able to help some of the folks learn to solder their parts together. Others
decided to just rely on electrical tape. We covered the connections with
heat-shrink tubing that we shrank with a small travel hair dryer.
It was a noisy fun group… and we all accomplished something… a perfect
example of project based, collaborative learning in action!
After lunch we tackled the temperature sensor, which is a much more complex
project. We had two different, conflicting, sets of instructions… one from
the wiki and one from the XO Explosion kit Mike Lee brought. Finally, we
found a third one, in Spanish, by Plan Ceibal, also on the wiki. It was a
lot easier to understand and the photos were very clear. Someone needs to
translate this one. We did get some reaction from the sensor, but it
obviously wasn't working right. This one needs more exploration!
We didn't get to the generic sensor (out of time), but it is pretty easy and
straightforward so anyone who made a light sensor should be able to make the
generic as well.
In the next week or two I will put a list of parts and instructions for all
three sensors on either the OLPC wiki or the Sugar Labs wiki with links from
one to the other. I'll send a link when it is done, and I invite everyone
who joined in the activity (or didn't but has worked with sensors before) to
contribute to the discussion there.
If you were part of this fun group and have a little time to spare, you
might play around with the temperature sensor and see if you can make it
work. Also, try the generic with some of the copper wire in your kit and an
ungalvanized nail to make a lemon battery. We will have a discussion place
on the wiki where you can report your activities and how they worked… or
didn't (failures are important too if they are documented so we can learn
from them).
What's up for next year's Sugar Camp? Several ideas were tossed around. If
you have any suggestions for fun, preferably hands-on, things we can try
with the XOs, speak up!
