Author(s)  tarwin, tiefpunkt

We need something to display to the world that the space is manned and open. And that switches on all the gimmicks and gizmos. =)

Current Setup


Right next to the door:

  • Big switch
  • Raspberry Pi


Source code:

The RPi posts the lab status to the MuMaBus. Changes are received by a script running on the webserver, which makes the current status available to a set of PHP files.

  • Runs on the Raspberry Pi
  • Checks status
  • Posts changes to the MuMaBus on mumalab/room/status

  • Subscribes to mumalab/room/status on the MuMaBus
  • Writes changes to the file system

PHP Scripts

Availabe at

  • index.php - Standard page with text etc.
  • image.php - Green or Red circle
  • simple.php - 0 or 1


  • Nices images
  • Something to react to the switch and send an IR pulse to the light strip
