Parts for "Simple Machine" book by Isogawa-san? I would like to make some models from The LEGO Technic Idea Book: Simple Machine by Yoshihito Isogawa.

It seems the author is using parts of different "Technic" sets.

Could you advise where can I get parts (or ideally a set) to make the models for the book?
There was a lot there, but the very last sentence from your Amazon link mentions to visit the No Starch Press website for a list of the special parts used in the book.

There the website includes all three books from the author's 
 LEGO Technic series:


The LEGO Technic Idea Book: Simple Machines. (Digital PDF of book here.)
The LEGO Technic Idea Book: Wheeled Wonders.
The LEGO Technic Idea Book: Fantastic Contraptions.


All with a few set recommendations directly from the author, where he suggests sets that have a wide range of parts in single set purchases.  

For parts left over, he offers a reference list with colored pictures of each part, and purchasing links to Bricklink.com.
