My digital camera is having trouble getting a decent photo of my design.
I can give you simple instructions for wiring it up.
In the meantime locate a datasheet for the DS275 chip from Maxim
(do a search for the part).
It has the pinouts there.

re: PT1501, this is also available - look for a post by Jan Harkes on this chip last week [do a search for it].

If you get the datasheets for the DS275 plus the PT1501 you're more than half way there!
