Quick Introduction to Development Boards
We had a presentation at the club's February 2014 meeting on the Raspberry Pi development board, an inexpensive and tiny little computer designed for education, experimentation and building practical projects.
Unfortunately we had a projector failure so we couldn't show some of the slideshows we had planned to.
The following links will take you to the presentations, along with other interesting projects that radio amateurs are building with these interesting little computers.
