It would be nice to have all the hardware related projects of OLPC with open designs and blueprints (PCBs),we should have in mind what is open source hardware (see also Open design). As OLPC is an Open project all its components must follow open related ideas.

Here is the open source hardware definition that should be followed.

But

Unfortunately, commercial realities intrude. The development of the XO required many millions of dollars of engineering, tooling, and test runs. The company building the XO, Quanta Computer, Inc., invested this, with the hopes of recouping it through their very small (and limited) profit on the manufacture over many, many millions of units. In order to ensure this, they are maintaining strict control over the actual electrical design of the laptop.

Anyway

OLPC is working to negotiate a more open design with the second generation.

Development

Actually there are two threads of development, one is making USB peripherals ( or XO Peripherals ), and the other is extending and improving the analogue input of the laptop trough applications like Measure, Turtle art and etoys, now there is a way to connect these sugar programs to the open hardware platform, Arduino. See sugar's wiki for more details.

Projects like Digital Signal Processing, the latter are in a superior stage because it need less external hardware support, but are tied to the requirements of the internal audio chip of the laptop.
