I find it very useful when trying to identify IC's in a random parts bin. Also if you looking for a part of a certain type all you need to do is hit [F3] on a simple note editor like windows notepad type in the part you looking for and walla you have the part, simples. This is probably the most important piece of software I use when working on projects.

The Art of Electronics - By Paul Horowitz, Winfield Hill

  • The thoroughly revised and updated second edition of the hugely successful first edition.
  • If there is one book you should get your hands on, its The Art of Electronics - By Paul Horowitz, Winfield Hill this is a must have for anyone studying Electronic Engineering. Its full of use full information about the subject. I highly recommend getting the hard cover edition as you will soon find that you need to reference this book quite often.
