Stick computing: GHz USB devices?

Game developer David Braben and colleagues are working on a tiny circuit board suitable for game development, with a few hacker-friendly ports, which will fit into a gumstix-sized package. They are calling the device Raspberry Pi.

Their stated goal is a device with a 700MHz ARM processor, 128MB of SDRAM, a USB (out) port, an HDMI connection, and an SD card slot… relying on the USB input for power.

Unlike Gumstix, which found a corporate and DIY niche for its boards, Braben is focused on minimizing the device’s cost, making sticks ‘cheap enough to give to a child to do whatever they want with it’ and to make learning computing fun. An admirable goal. The project already has its naysayers, however, as it is hard to hack without many peripherals as well. What would you do with one or a few of these?

Comments on Jeffrey James’s olpc critique

By Antonio M. Battro, OLPC’s Chief Education Officer

Jeffrey James wrote a critique of OLPC last year, proposing a balanced pattern of “sharing computers” among children (say 5 children per computer, in the US or the UK) instead of the olpc “one to one” model – one laptop per child (and per teacher). As an alternative to olpc, James proposes that “the number of students per laptop stands in roughly the same ratio as the difference in per capita incomes between the rich and the poor country” (p. 385). In his view, the OLPC idea to persuade the developing countries to exceed the standards of shared computers of developed countries seems “utterly perverse” (p. 386).

It seems that his reasoning will fail if we substitute mobile phones for laptops. We don’t frequently share mobile phones, and in many poor countries their number exceeds James’s predictions about ratios of income and information and communication technologies in the hands of people. It seems difficult to accept the universality of his model about “sharing”, because laptops, tablets and mobile phones are rapidly converging in new hybrids.

On the other side, his ideas for successful low-cost technology sharing are not clear. One of his options, for instance, is “to purchase Intel’s Classmate computer at a similarly low price and let [them] be shared by as many students as is thought desirable” (p.389). In Argentina, where the Classmate has been most widely adopted, the national government is deploying some 3 million Classmates to cover the whole population of students and teachers of the secondary public schools in the country, on a one to one basis – an idea first proposed by OLPC some 5 years ago. It would be interesting to know the current state of affairs of other options he references (Simputer, NComputing, sharing multiple mice). However the quoted references are from 2006 and 2008, and 3-5 years is a long time in the digital era.

From the point of view of psychology and education, some comments about “teaching” need careful revision. First, in his paper James never speaks of the need to give laptops to the teachers, despite the significant mass of teachers in the world. On the contrary, OLPC programs start in every country by giving a laptop per teacher and providing corresponding teacher training. We know that a) “digital skills” develop in stages from the very early ages, as a second language (Battro & Denham, 2007) and b) most teachers didn’t have the opportunity to early access to this new global environment in the poor and developing countries.

butiábot: XO Linerider robot in action

Team BUTIÁ from Uruguay has been working on an XO robotics project for over a year. They showed off their line-following XO-robot, butiabot, in Montevideo this weekend. An XO running TurtleArt code hooked up to a mobile robotic platform followed a dark line along the ground.

They have posted some details of their prototypes online.
This reminds me of the XO hack to control a Roomba over the Net, but cooler, with Turtle Art and a realtime-hackable control program.

OLPCistas in Uruguay this week and next

Over 20 OLPC and Sugar collaborators are in Uruguay this week, visiting schools, meeting with the Uruguayan communities (ceibalJAM, RAP Ceibal, and the eduJAM event team), and preparing for the eduJAM! summit for Sugar developers and educators across Latin America.

The attendees are using a separate OLPC Uruguay 2011 blog for the week to track their various travels and projects in Uruguay. If you can’t be there yourself, you can follow along (and share your own questions for the group) here.

Tablets and the future of knowledge-sharing

From a recent letter to the editor at Education Week:

Tablet PC learning can provide basic knowledge needed by everyone—English, math, basic physics, and science, hygiene, “How Stuff Works,” and “Rules of Considerate Conduct.” A memory stick instead of a textbook for each K-12 subject would provide continuity. It also would allow students to learn any time in any place on any path at any pace. A memory stick can hold an entire K-12 course, including embedded and practical test questions.

The One Laptop Per Child project has provided more than 1 million laptop computers worldwide. Soon the project will make a tablet PC available… Tablet PCs are already available… this approach to learning is not new. This is the future of schooling.

Documenting life on Earth – Abel and his XO

Last July 24, thousands of people all over the world submitted their videos to YouTube to share their lives, to participate in Life in one Day (La vida en un dia). This was an experimental bit of cinematography to create a documentary created entirely by YouTube users, capturing one day on Earth. Ten OLPC students from Peru took part, posting videos of their day for the project.

Now all of the stories have been edited together into a single documentary.  The film was directed by Kevin Macdonald and produced by Ridley Scott.  National Geographic is helping with distribution.   Rick Smolan was also involved in the film’s development last year.   Since its global online premiere at Sundance, the documentary has been received enthusiastically at the Berlin and SXSW film festivals.

The film will be shown in theatres across the US this summer.

Here is the official trailer:

 

And here is the story of Abel, an 11-year old shoe shiner and one of Peruvian gen-XO children who took part – part of his video was included in the film, showing his life working on the street, and what he loves to read on Wikipedia. He and his father had the luck to be flown out to Sundance for the online premiere!
