RGB LED Coffetable – Rainbow Carnival 2010 Entry

My entry for the Rainbowduino Carnival 2010 by seeedstudio

A standalone RGB LED Coffeetable

I wanted to have something really usable for the livingroom. No laptop pushing over Data, wires lying around, Seeeduino to Rainbowduino etc

So i built a Coffeetable with a handsoldered 64 Superflux Pixelmatrix and the Rainbowduino. It uses a 9V PSU, but can also be powered via Battery.

To keep an environment-friendly approach, every possible part was made with recycled resources – the matrix of cardboard is made from the packaging of the table, the wooden floor and side parts of the led-matrix-housing are repurposed from an old cabinet.

Greetings

    Really wonderful and so nicely crafted. Have you thought about using the Grove touch sensors below the surface so you can interact with the table without any visible buttons or controllers? Maybe develop a simon memory sequence game or a light version of checkers. Or maybe just an interactive way to design and input new color pattern programming via touching the table top… Just ideas, would love to hear more about what you have planned for your creation. It really is quite spectacular just the way it is! Thanks for sharing this with us.

    Nice project. I keep telling myself I’ll put one of these together myself.

    Can you lend me a shematic? I’m needing to build one 6×9 RGB leds matrix. Thanks

    Ah okai, this neorainboduino is nice! Actually only half of the examples work…
    @sawomedia: would you mind sending me the your code for the animations? (greenfly(AT)riseup(DOT)net.

      Hello there greenfly! Sorry for the late reply. I used the patched MeggyJR Library together with the standard Firmware. http://code.google.com/p/rainbowmcompat/

        All thanks go to the creators of the patched lib. I tho already have games running standalone on the desk. Remember, the Rainbow is an Arduino. You can see some Analog ins brought out on the board, also you can reconfigure the ISP Header to be Digital ins.

        Hey sawo! Thanks for your reply. Great idea to connect the MeggyJR to rainbowduino. Maybe we could make the MeggyJR Library(on an arduino) send I2C to the rainbowduino? So we could add Buttons and everything to play funny games on the table!
        (I like the idea of not having to use a computer everytime I use the table…)

    greenfly: Hm… my last comment is awaiting moderation since a week… maybe because I posted a link to the Rainbowduino manual where I found the 4A maximum.
    What is the actual height of you “pixelboxes”?
    And im looking for some example rainbowduino code… the different firmwares are a bit confusing to me at the moment.
    How did you do your animations?

    Nice! How did you figure out which Led cable goes to which pin on the rainbowduino?
    And (roughly) how many meters of cable is used?

      Hey there! I made a RGB Matrix, connecting all R,G,B Leds in Rows, and all Common Anodes in Columns. So you have 8 x 8 Connections, that fit the layout of the Rainbowduino.

      I think i used 4 x 15m each R,G,B and K wire :D

        sawomedia: No, i never heard it draws 4A. You can use this desk even with a 9V Battery. Where did you read this?

        I found this in the
        manual.
        What is the height of your “pixelboxes”?
        Im trying with 9cm now, it’s pretty even now, but with smaller height it may be brighter…?

        No, i never heard it draws 4A. You can use this desk even with a 9V Battery. Where did you read this? I am using a 750mA 9V PSU atm, never had any problems. I never touched the potis, because the LEDs are very bright. I messed up with the pots on one of my other Rainbowduinos, and fried a RGB Matrix, so be careful!

        Any Problems with the PSU until now? Course in the Rainbowduino manual it says “draws up to 4A at maximum… and how did you adjust the potis? just by eye?
