Dr. Simon Monk (Preston, UK) has a degree in cybernetics and computer science and a Ph.D. in software engineering. He spent several years as an academic before he returned to industry, co-founding the mobile software company Momote Ltd. He has been an active electronics hobbyist since his early teens and is a full-time writer on hobby electronics and open-source hardware. Dr. Monk is the author of numerous electronics books, specializing in open-source hardware platforms, especially Arduino and Raspberry Pi. He is also co-author with Paul Scherz of Practical Electronics for Inventors, Third Edition.

Duncan Amos (Catalunya, Spain) built his first crystal set at age nine, attended a school that offered an electronics class (very rare when transistors cost a small fortune and were supplied in individual boxes, packed in a cotton ball), took holiday jobs in the fledgling UK computer industry and began full-time employment as an apprentice in a company that produced TV broadcast equipment. He has been involved with producing printed circuit boards for almost 50 years and has straddled many industries from environmental monitoring to aerospaceseveral of his PCBs are in earth orbit and continue to function after more than 25 years in that harsh environment. Although officially retired, he continues to produce PCBs and electronic designs for non-profit groups, small companies and start-ups, and regularly performs technical reviews of books on electronics.

S ince this book was first published, EAGLE has undergone several version upgrades. The first edition was based on EAGLE v6.3.0, and within the version 6 iterations up to v6.6.0, the changes were mainly the usual mix of bug fixes and relatively minor improvements, although several were very welcome. All the version 6 iterations use a new data structure and came with this warning:

WARNING: The data structure in this version is completely different from that in older versions! Once you edit a file with version 6.x you will no longer be able to edit it with versions prior to 6.0!

PLEASE MAKE BACKUP COPIES OF YOUR CURRENT BOARD, SCHEMATIC AND LIBRARY FILES BEFORE EDITING THEM WITH VERSION 6!

In July 2014, CadSoft launched EAGLE v7.0.0, which was a significant upgrade to the previous v6.6.0.

Many things changed in v7.0.0 including a new icon set; changes to the licensing; and the ability, with the free version, to have two schematic sheets linked to a PCBa list of the major items can be found at https://www.element14.com/community/thread/36503/l/eagle-version-70-released. v7.0.0 also came with a warning:

Update from Version 6 to Version 7

If a version 6 drawing is edited in version 7 and the new autorouter or hierarchical design are not used, the drawing remains down compatible to version 6. If these features are used this compatibility can get lost once a drawing is saved. For this we recommend to make backup copies before editing version 6 drawing files in version 7.
