Wol Posted October 22, 2013 Share Posted October 22, 2013 It's like a massive scale version of the SGM stand from Plasa last year. Although they use Madrix not Arkaos Link to comment Share on other sites More sharing options...
MarfaLights Posted October 22, 2013 Share Posted October 22, 2013 352,512 pixels is 689 universes assuming single color pixels. Can somebody help me understand how this is interconnected between ethernet and individual led strips? Link to comment Share on other sites More sharing options...
dbuckley Posted October 22, 2013 Author Share Posted October 22, 2013 A lot of boxes, each with an Ethernet port and a one or more (probably more, like 8 or 16) port(s) to send digital data to the LED strips. I'm guessing now, but each strip looks long enough that it will have its own control wire back to the box. Converting Ethernet to DMX512 would be a cost that doesn't make sense.

MarfaLights Posted October 23, 2013 Share Posted October 23, 2013 That makes sense. Perhaps each pixel is either on or off and not dimmable. Or each pixel is simply 4-bits of RGB-0 for seven colors. Each of the 3264 strips has 108 pixels. If these are RGB pixels then you have only 432 bits to define the state of one strip. 1.4 Mbits defines the state of the entire installation. At 30 frames a second you need 42Mbit/sec data transfer. That's easily handled by USB2.0 speeds. So I can see some dozens of ethernet boxes that could each control dozens of strips. Give me a few hundred Arduinos and a month... Am I on the right track? Link to comment Share on other sites More sharing options...
callumb Posted October 23, 2013 Share Posted October 23, 2013 How about only one ardiuno pin? http://www.phenoptix.com/products/adafruit-neopixel-stick-1426-uk they do sell strips and leds. Although the ardiuno can't handel too many leds as I will run out of ram! :( Link to comment Share on other sites More sharing options...

It does require a whole shedload of universes but that's the way it goes with pixel mapping, control systems such as Madrix can handle it. Have a look at the product pages for the SGM fixtures shown in the second video and that will explain how their system operates. the led tube...http://sgmlight.com/...0200/c-23/p-148 the driver box...http://sgmlight.com/...12-a/c-23/p-194 Link to comment Share on other sites More sharing options...
