Sorry, this is wrong.  You are thinking of copyright law, which has
exemptions for "fair use".  THERE IS NO SUCH PROVISION IN PATENT LAW.
A patent owner has absolute, total control of his invention (assuming
he has the resources to find and sue the violators).  Building one for
your own personal use *is* a patent infringement.  Of course, in
practice the patent owner (a) probably won't find you, and (b) probably
won't bother suing an individual who's not making a profit on it, but
legal it's not.
