Yea i have seen the schem. and you can feed it with a wall-wart.
You need about 17V or more of DC on the 7815 input for it to work
properly, how you get that doesn't matter.
In case you get a wall-wart with regulated output of 15V you can hook the
7805 to that and connect without the 7815 to 15V.
You know this is getting pretty off topic, there is another group,
Electronics_101@yahoogroups.com, where most of the people here are also
around and where it is much more on topic.
