[olpc-nz] OLPC Drives RepRap now

[Vik Olliver]

At long last I have code to drive a RepRap using an OLPC. It's just a
couple of command line utilities written in C that can generate gcode
and dump it to the serial port.

The next release of the RepRap hardware should be capable of running off
a car battery for 16 hrs - should be in beta in a couple of months.
Currently it costs 5x what an OLPC does, but we'll try and improve on
that. It looks like we're rapidly converging on a 3D printer that will
be usable in developing countries.
