Next Saturday, March 15, 2014 is Hardware Freedom Day (http://www.hfday.org/).
From the web site: "Hardware Freedom Day is a yearly celebration of Open Hardware! Every year since 2004 hundreds of teams have been celebrating Software Freedom Day, often showcasing Open Hardware in the process. At the Digital Freedom Foundation (formerly known as SFI) we thought it was about time to have a special day just for Open Hardware. So for its second year please get your hackerspace in order, your team up to speed and register your event right now!"
Several of us from FREDLUG will be at the the Salem Church Branch of the Central Rappahannock Regional Library from 9-4PM with some of our open hardware!
I plan on bringing some Arduino projects including the one below with a remote, Arduino mini, speakers, and a relay module.
I also will bring one of my Maple Mini systems (72MHz ARM, 128K FLASH, 20K RAM, Arduino-like interface and toolset).
I also plan on bringing some Raspberry Pi systems that run Linux. While not completely free and open hardware, they are great for education. AFIK, someone else will be bringing the superior Beagle Bone Black which also runs Linux.
Papilio One FPGA board with a "logic start wing" with lots of buttons and switches. This is programmable hardware!
