For a picture of Poncet Platform you can go Robert Duvall's page which
has an article on a platform built by Jean-Marc, the address is:

http://www.jlc.net/~force5/Astro/ATM/Poncet/Intro.html

As for the circuit diagram that controls the motor, go to this address
(it's also in Bob Duvall's page, and it's mentioned in his Poncet page,
but you can not follow the link from there, at least I couldn't),
according to the article this is the same circuit he uses for the
platfom:

An equatorial platform is next on my list of "Things To Build" (the list
is getting longer, I don't know why :-) ), does anybody know other
source of reading for equatorial platform? I only know Robert Duvall's
and Chuck Shaw's.
