Blinkenwall..

  • is the wall between our mainroom and the library
  • in this wall are 9x5=45 glassbricks installed
  • next to every glassbrick there is one RGB-led with a pretty neat chip attached
  • these presoldered boards are called Shiftbrite
  • they are currently controlled from an arduino this may change soon for something with more computational power :)


How

Sample effect - https://whatever.metalab.at/user/meta/blinkenwall/WallSample

We just connected the Arduino to a fonera 2200 over serial.

Now its possible to stream data for display to the blinkenwall using your favourite webbrowser.

url soon to be added here..

Lessons learned:

  • one can somly connect RX/TX from fonera to arduino
  • no stty in default openwrt busybox build
  • openwrt building is an fairly easy task
  • replacing the busybox binary on a live system during operation is insane and possible! :)


Reference


Who

  • Metaz - arduino library software for shiftbrites
  • Wizard23 - help with electronics, basic software setup
