Re: [IAEP] [Sugar-devel] Sugar Digest 2012-09-18
The situation is sad, but it's True. In a school the teachers can start an unusual class and try other ways for teach and the students (6 to 11 years old in .UY) follow the instructions of the teachers. In a high school (12 to 18 years old in .UY), teachers have 45 minutes per class and one year for teach a list of contents. In 45 minutes, there's not time for try another working method and when they do it students use the web browser for log into social networks without permission of the teacher. So the teachers prefer the traditional class where they already know how to have all the control in the classroom. I think the expected usage of Sugar and computers in the classrooms here, is happening slowly only in primary schools.

Re: [IAEP] It's Time to Sign Up For Sensors!
Hi Mike and All, Yes! Bring your temperature sensor kit. We can put it together in SF and try it out. I think for the parts kits I am assembling for folks to build, I'll go with the thermistor. It is less expensive and easier to find in time for the summit. It also doesn't need the additional usb cable for power supply to the sensor. I think people will appreciate lower cost solutions they can use in their deployments. There are also some interesting calibration lessons the students can do with the thermistor too. It will be interesting to compare yours, which uses the LM35D sensor, with the ones with thermistors. You mentioned using heat shrink tubing. I have a small travel hair dryer that puts out really warm (actually hot) air. Do you think it might work for this? I'm making the parts lists now and will work on locating an getting the stuff after the weekend. Some things are readily available locally, others may have to be ordered from a supply store that offers 2-day shipping. When I get the list finished for editing, sometime tomorrow, I'll send it out so people can check it over for me and make any needed corrections and suggestions. I would appreciate it if everyone with electronics experience could look it and make suggestions... even it you aren't coming to SF or are coming but don't want to build and play with sensors while you are there.

Re: [IAEP] It's Time to Sign Up For Sensors!
I must have missed it if there was any comment on it, but Claudia Urrea has been working on sensors for many years already - 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? 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.

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. 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. 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
Re: [IAEP] It's Time to Sign Up For Sensors!
Caryl, Using a hair dryer for heat shrink tubing is hit or miss depending on how hot the dryer gets and the type of tubing. Northern Tools has one for $20. And Sparkfun a smaller one for $10. It's a worthwhile investment. http://www.northerntool.com/shop/tools/product_200328563_200328563 https://www.sparkfun.com/products/10326 Electrical tape can certainly be used, but I find that long term it peels off. I take a significant amount of cords and electronic doodads through TSA regularly. I find that you'll only be hassled if the wires are parts are all mixed together making it hard to tell what's there in X-ray. I just keep a ball of rubber bands around and neatly coil and band each cable, and put small parts in clear zip lock bags. And you can store it in checked baggage if you're doing that.
