your advice, and help, is so very much welcome. but perhaps I misunderstood=
 the purpose of this "learning" board.  can they give me a "learning" board=
 to experiment with analog stuff, then expect me to know enough to create a=
 10v power supply?  that is what my problem is.

I can of course put together the circuits that create a 10V power supply, b=
ut, in my defense, such a learning sort of  board and stuff shouldn't expec=
t me to know how to do that.  Should they?  This is just a learning/develop=
ment board.  I pay not so much to buy the circuits and the board, but more =
the "how to" part of it all.  Well, it was a gift for a friend who knows  n=
ot too much, but wants to learn.=20

now, how do I tell him that I need to put together a bread-board with the r=
ecommended IC's to create 10 volts from, say 9 or whatever (4 AA's in seque=
nce).  Or some sort of AC to DC power supply such as a wall wort.    I am j=
ust not smart enough to bridge the gap between me and him.  but I really am=
 trying my best to learn this.  (I have Horowitz in my shelf, also Boyelsta=
d.)  Ahhh.

bestest regards, Lindy
