RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer.

There are 1,000s of Pages Indexed on RF Cafe !
Each week, I select a new book that is relevant to engineers, scientists, students, hobbyists or managers. Most of the time they are sold through Amazon (I earn a few pennies on each sale), but when possible, I present books that are available in an e-book format that can be downloaded for free. The latter are much less available. After all, most people like to be paid for their work, as I'm certain that you do, too.
Note: I just began archiving these picks in May of 2009, but they have been going on since about 2003.

An Affordable Personal
the early 1990s a decent flatbed scanner from HP cost started at about a kilobuck - the price of a nicer notebook
computer today. 3D printers are at that price point now, and in all likelihood will be in the $250 realm by
2020. You could easily justify the investment for company use and/or use it to provide an impetus for getting
your kids interested in high tech and in using computers for something other than Facebook. The
Dremel Idea Builder 3D printer is quite affordable and has the reputation of a great company to instill
confidence and very high customer ratings! Software is included for designing printable items.
