Volter,
Is
this site the one that shows the clock? If so, the second paragraph underneath the bulleted list has the links
to both the construction website and the power supply website. The power supply site has everything on that page.
The construction site has a link on the side that says DOWNLOADS. On that page, the first set of links are for 1) the
schematic in .PNG format, 2) schematic and board layout in Eagle CAD and 3) the enclosure in SVG format.
You should be able to open the .PNG just by clicking on it. Windows will read it just fine.
You'll need Eagle CAD in order to read the next 2 files.
I don't know, offhand, what a SVG file is.
Hope that helps,
