But the thing that struck me about all of these different projects is that they really had to be built from scratch, down to the level of the electronics and the printed circuit boards and all the mechanisms all the way up to the software.
Mas o que me chamou a atenção acerca de todos estes projectos é que tinham que ser construídos de raiz, desde o nível da electrónica e dos circuitos impressos e todos os mecanismos até ao "software".
