Where projects are the units going to?

  • Dana wants to take 20 units for a community project (I'm in possession of 14 units as of 2013.11.27. If any go unused I will return them for other uses. ~ dana)
  • Sudoroom is interested in all the units for their open mesh networking project.
  • Dan would like at least 1 outdoor version and 5-10 boards to provide wifi in the Mission around Noisebridge. https://openwireless.org nodes
  • Adrian wants several to improve Atheros support in FreeBSD
  • Jof wants boards for mesh testing
  • J.C. has 2 boards for testing.
