control the Yamaha AV system, our MHS and projector using a web page.


source on github: (latest slackomatic release, latest artnet4j fork release)

Current state

  • you can select between the Screeninvader, PS2, PS3, Wii and one spare HDMI cable (labeled "My HDMI Port") and a Phillips Bluetooth "Headset".
  • projector, tv screen and yahama are now connected with a shiny new HDMI cable (and an HDMI splitter to display the same on the TV and projector)

Known issues

* change to the invader can fail sometimes (change of the projector input source), please try again after a few seconds.

* video quality on Wii and PS3 is a little bit sub-par (needs a new cable between the Yamaha and the projector).


  • support all the other stuff in the lounge (Kouch, Metacade et al.). those will be added when the necessary cabling is available.
