Many of the highly advanced technologies on Blue Star can be easily achieved here through the extraordinary power.
Although there are not many extraordinary people, they are able to produce some very precise and magical devices, which make other industrial productions less difficult.
Thus, when the Extraordinary Association developed the first radio, they gained confidence, believing that ordinary people might be able to produce radios without the help of the extraordinary ones in the future.
By using magical materials, very small vacuum tubes can be produced and arranged within a relatively small crystal.
This is a very clumsy method.
But everyone needs to use this way to increase their understanding of electronic circuits.
Chemical etching is new to the world of Gaim, and etching such precise circuits is even more difficult.
It doesn't matter if the size is a bit larger, as long as it works.
