You are empowered. Everything about the Arduino is open. You have access to the schematics, the board layouts, the source code, the tutorials, the user forums, and everything else that is Arduino. With all this at your disposal, why not build your own Arduino?
You can buy a blank Arduino-compatible PCB from several sources, collect the necessary components, solder them into place, and voilà! You can say that you built your very own Arduino. The Freeduino project (
