One Laptop Per Child

February 24, 2008



One Laptop Per Child, a computer initiative by Nicholas Negroponte is a unique machine with features created specifically for children of the emerging world. This is a very distinctive machine; rugged, durable, and child-friendly, inside and out.
XO is about the size of a textbook and lighter than a lunchbox.
Its NiMH batteries contain no toxic heavy metals and has extended recharge-cycle lifetime. It will also tolerate alternate power-charging sources, such as car batteries. The XO can be solar or foot powered. It will come with at least two of three options: a crank, a pedal, or a pull-cord. It is also possible that children could have a second battery for group charging at school while they are using their laptop in class.
XO has no hard drive and only two internal cables. For added robustness, the machine’s plastic walls are 2mm thick. Its mesh network antennas double as external covers for the USB ports, which are protected internally as well. The display is also cushioned by internal “bumpers.”
It has a clock speed of 433 Mhz, Integrated Graphics controller, 256 MiB dynamic RAM, 1024 MiB SLC NAND flash, 7.5” Dual-mode TFT display, WiFi, 640×480 resolution integrated color vision camera.
