Paper, scissors, XO

October 21, 2009

A small photo or video with the XO? This is what makes the activity Record / Record .

Yes, but ... not easy to frame precisely when the XO is not equipped with a camera viewfinder.

Of course, there are alternatives:

A / Obtain a viewfinder as here or there .

B / To make a viewfinder

Be used for this 3D printer RepRap

C / Make your own custom viewfinder

There are in Legos , or cardboard.

But we keep the best for last, with our reinterpretation of the game " sheet, scissors, stone XO ".

Materials required:

  • A sheet of cardboard
  • 1 pair of scissors
  • An XO

Instructions:

  • Cut the cardboard into a rectangle of 105 x 7 mm
  • Bend so as to form a square and join the two ends

  • Place the viewfinder folded into the USB port the XO as shown below

  • Aim for

Cheeeeeeese...

Cheeeeeeese ...

The genius is it soluble in comfort? This is what might suggest the many examples of inventiveness that have been reported outside of the OLPC project. Thus we learn that members of the program OLPC Afghanistan have devised and implemented a prototype of "pedal for XO" responsible for producing the energy needed to power the XO computer.

This realization, or the device bicycle-generator-battery powering an XO, a school in Uruguay (" Transformando mecánica in the energía eléctrica "), inevitably evokes the mythical crank, still associated with the first prototypes of the XO. This accessory was eventually abandoned because of its inadequacy. A paddleboat in Afghanistan, a crank in the labs of MIT, a micro-turbine in the village of Malagasy Antitorona, on the island of Nosy Komba , or solar panels, as in San Mahen , Sierra Leone: what are some some of the ideas more or less successful, that we owe the OLPC project or associated with it.

Clearly, there is ingenuity in these creations. But how many other geniuses anonymous and unsung countries "developing" they contain? For it is understood that inventiveness is not the prerogative of the XO computer, as illustrated by the brilliant young William Kamkwamba in Malawi, who designed and built wind turbines in a context of extreme poverty, and whose the term "typical-atypical" gave rise to the story " The Boy Who Harnessed the Wind ".

But even if there is no strict determinism between the possession or use of technology such as the XO and the educational benefit that can be drawn, it appears that this learning platform has been designed to foster creative and critical attitude among its young users.

An educational platform hackable

OLPC has indeed registered the ingenuity among its principles. The ingenuity is that of users of this educational platform designed to be sturdy, "green" and open. Users are encouraged to compete and intellectual audacity to make the most of their XO and the best use of the constraints imposed by the lack of adequate infrastructure and, too often, the most acute deprivation.

Thus, various devices and equipment have been designed to accompany the XO computer. We find a listing on the OLPC wiki page devoted to devices , whether for powering the XO power or to ensure its connectivity with the rest of the world. Other projects have begun to address these needs by an "all in one," as that achieved by the project Labomobile and Green-Fi in Senegal.

Other creations, just as original, continue to emerge from the inventive minds of their designers, such as robotic 3D printer RepRap . This can be enlisted to manufacture in series of other accessory, the camera viewfinder's XO.

Not trivial either, in the project design of an electro-cardiogram (project OLPC Golden State ).

Finally, the day your XO will pass on the "pool" after any failure, repair it yourself or have it repaired in a local service center. Join us for this, near Paris, to / tmp / lab .

Too far from home? Never mind, move closer to other Repair Centers , or create one yourself ( How to start a repair center )!

The future is yours, just invent the Happy Hacking!
