Gerber file is a universal Ecad format ,it means you don't need any spacial
cad to use it .
A view of gerber file opened by cam350 .
As you see it includes all layers you want to print .

forgiveness for the translation of google, I'm Spanish.
. zip file if I open it.
files inside no, that program needed?

[oxygen007m]

Just use winrar or winzip to unpack the gerber file
Use a gerber viewer like cam350 and then you have pcb file
with exact details and dimensions .

hello, oxygen007.
which brings the file types .zip? I can not open them.
you have a photo of the finished device, thanks.

[oxygen007m]

For those who interested in single layer pcb , I also have attached the
gerber file . There is not any error with pcb , so use it with confidence .
enjoy boys

Hi . A better retrace of surf pi schematic with altium by me .
I also replaced old 2N3906 with BC327 and audio output transistor with
BC337 which is more available on the market .

long time ago, I built the files posted by Stefano but does not work . I do not know if I have wrong in the assembly.
The project is very interesting, the PCB is very small, someone could build it, maybe I missed the assembly.
excuse my bad english.

Thanks a lot Stefano. I think this is the 3er version on sprint layout file.
Very nice.
