LED wall and Kinect join forces

[Alex] wrote in to let us know about this Kinect controlled LED wall that was whipped up at the Tetalab hackerspace in Toulouse, France. The wall, which was built earlier in the year, uses some MAX7313 LED intensity controlling shift registers. Each gets its own board and controls the intensity of sixteen different red LEDs. They’re embedded in the wall module and covered with ping-pong balls as diffusers.

The recent activity on the project takes advantage of the Xbox Kinect. As you can see in the video after the break, they’ve used the open source Kinect drivers to capture 3D environment data, processing it into color gradients which are displayed on the Pong wall. Shouldn’t be long before they someone comes knocking on their door to install this in a dance club. We love the effect, especially because it works in a dark room and the LEDs don’t cause any interference with the video capture.

    Set it up in there, would be awesome.

    Thats awsome. Those Guys rock!

    Les funky!

    Dance club? I’m not sure this has the resolution to capture a chick who can REALLY shake her booty. Then again this could transform her shaking into a truly bizarre image

    Look, Kinect is the new iPhone!
    WTF is this, they used video feed of a webcam and claim Kinect hack? …

  6. fab says:

    @rasz This not a webcam feed the brightness changes with kinect depth

    @D_
    The resolution could be improved, the limit is 1024 PWM leds driven (64 MAX7313 x 16 leds) on each I2C bus.
    We just stop to 432 led (16×27) because we had a free bag of 500 toshiba TLRH180P red led… that’s all

    @rasz
    We did not claim hacking the kinect, we wanted to use the fresh open drivers as depth measurement to render it on our ledwall.
    And using a video feed of a webcam as already been done by our team about 6 month ago…

    And really big thank’s to the DDF team who inspire us this collaborative work and all the people working on liberating the kinect.

    A regular camera would only be able to capture colour/tone and brightness. Kinect detects 3D, so the closer you are, the brighter the LEDs will be on the wall.

    Unimpressive.

  10. IJ Dee-Vo says:

    Most impressive

  11. Da 1 Guy says:

    that makes me wonder if anyone could use this concept, but ise servos to rotate the balls, have them divided into three colors or shades(white led mounted inside the colors could be primary and the ammount of light to change shades& black), kind of based on the compas tabe i saw on instructables
