Wow I thought so too. So there are 4 members on her that are in the Placer area including myself?

Here I thought I was the one of the only houses in Rocklin that is a DIY member.  Cant wait to see the house, I think I will have to see it tomorrow night.  I am the house on Onyx drive.

There are at least two more on Do it yourself Christmas as well.  One in Roseville and one in Rocklin.

   Very, very cool.  Thanks for sharing.

I hadn't said anything yet, RJ, as I didn't know if you were announcing anything yet.

Yup- really looking forward to sharing how, why, and pitfalls to using this method. I cannot tell you how much I'm looking forward to 2012! I feel like 2011 was a proof of concept year and 2012 will be the first "polished year" for this method. Looking forward to seeing everyone at the Academy!!!

Very nice! Love the vertical SS stuff on the house and in your tree.

So here is the sequence that Sielbear designed and I implemented onto my display.  The LOR file is in excess of 1GB for this sequence.  To me it is the best use of the pixel technolog that I have in my display so far.  Special thanks go out to Alan at Lipton lights for the inspiration and the video file that serves as the bassis for this sequence.  It is in essence an entirely video driven sequence.

Enjoy!

1 Gig in size?!? Are LOR sequence files that inefficent and/or uncompressed? The computer I'm using with Vixen this year has only 256 MB of RAM in total!

[sielbear]

Yes- 1 GB for 1 song. Before converting to xLights format, my 8 songs used 9GB in space. Every 30 or 45 second segment of show was 200 MB. (45 second segments were 10 fps and 30 second clips were 15 fps. 450 frames of data per file.)

One other crazy... Using xLights to stream the show to my etherdongle had sustained traffic of over 1 megabit per second. That might not sound like much, but the video that was created in the divx format to create the show was perhaps 200kbps. Full hd is perhaps 3-6 Mb depending on compression used. These complex  shows push a LOT of data!

[frankr]

hmmm... That 1Mb number seems a bit high.  xLights will push 1 byte per channel 20 times a second. so 1Mb == 128KB/20 = 6,400 channels configured or ~12 e1.31 universes. 

If I remember correctly Alan your show is ~4500 channels so you should be pushing about:
4500*20*8= 720Kbps
Plus overhead (~144Kbps, but that is a total guess of 20% overhead)

That is indeed alot of data...

[sielbear]

I'm wondering how often "empty / unused" channels might get data packets. I defined 16 e1.31 universes, but using 4166 channels.

I do see a large flux in data between busy and calm areas of lights. I'm really curious what else might be sent. I had approximately 128k when idle. I averaged 1.2 Mbit with multicast traffic.

MTU is set to something like 1500 bytes I think so each frame of data would need 3 tcp/ip packets at minimum?

Eh.. My brain hurts. Time for a frosty new year's beverage!

This is so awesome.
