Did you know?
  • The original Rudolph did not have a red nose. In that day and age, red noses were seen as an indicator of chronic alcoholism and Montgomery Ward didn’t want him to look like a drunkard. To complete the original picture, he was almost named Reginald or Rollo.
  • The Christmas wreath was originally hung as a symbol of Jesus. The holly represents his crown of thorns and the red berries the blood he shed.
  • The three traditional colors of most Christmas decorations are red, green and gold. Red symbolizes the blood of Christ, green symbolized life and rebirth, and gold represents light, royalty and wealth.
  • Tinsel was invented in 1610 in Germany and was once made of real silver.
  • The oldest artificial Christmas trees date back to the late 1800s and were made of green raffia (think grass hula skirts) or dyed goose feathers. Next the Addis Brush Company used their machinery that wove toilet brushes to create pine-like branches for artificial Christmas trees that were less flammable and could hold heavier decorations.
  • ‘Jingle Bells’ – the popular Christmas song was composed by James Pierpont in Massachusetts, America. It was, however, written for thanksgiving and not Christmas.
  • Coca-Cola was the first company that used Santa Claus during the winter season for promotion.
  • Hallmark introduced their first Christmas cards in 1915.
  • The first recorded date of Christmas being celebrated on December 25th was in 336, during the time of the Roman Emperor Constantine. A few years later, Pope Julius I officially declared that the birth of Jesus would be celebrated on that day.
  • Santa Claus's sleigh is led by eight reindeer: Dasher, Dancer, Prancer, Vixen, Comet, Cupid, Dunder (variously spelled Donder and Donner), and Blixem (variously spelled Blixen and Blitzen), with Rudolph being a 20th-century inclusion.
  • Outdoor Christmas lights on homes evolved from decorating the traditional Christmas tree and house with candles during the Christmas season. Lighting the tree with small candles dates back to the 17th century and originated in Germany before spreading to Eastern Europe.
  • That big, jolly man in the red suit with a white beard didn’t always look that way. Prior to 1931, Santa was depicted as everything from a tall gaunt man to a spooky-looking elf. He has donned a bishop's robe and a Norse huntsman's animal skin. When Civil War cartoonist Thomas Nast drew Santa Claus for Harper's Weekly in 1862, Santa was a small elflike figure who supported the Union. Nast continued to draw Santa for 30 years, changing the color of his coat from tan to the red he’s known for today.
  • Christmas 2018 countdown has already begun. Will you be ready???
  • Why do we love Christmas? It's all about the traditions. In this chaotic world we can miss the "good old days." Christmas reminds us of that time.

ok so obvious starting planning for next year

 

im going with a 10 foot RGB full LED pixel module (WS 2801 IC) ;DC5V input with 32 strands of 25 nodes each strand.

 

i was thinking of using this controller http://sandevices.com/E681info.html

 

but will need to figure out how to power it, i can use cat5 cable? but how?...can you guys help?

Ernie,

 

I used CAT5 cable for my 6803 and 2801 strips and strings this year and it worked very well. The WS2801 pixel strings however had a 10% fail rate on individual pixels. Now I do live north of Seattle and we get a lot of rain. The strings where rated IP67 but I don't think they kept the water out.

 

On the CAT5 cable I used the White/Orange as the CLK and the Orange as the DATA. Then I used all the solid color wires as + and the striped wires as - for the DC voltage. I soldered them on each end to make sure they stayed together. I made my runs about 34 feet and did not see any issues with data or power. I only powered 50 pixels on each run. It sounds like you will have more pixels on each universe so you will need to run a seperate power lead to each additional strip/string.

 

I use the the ECG-P12R from J1Sys http://www.j1sys.com/ecg-p12r/   I went with this one because I can have on half powered 5 volt and the other half 12 volt if I want. They work great with the LOR software on E1.31 protocal.

 

Your Software questions is not as easy to answer. It really depends on how you want your tree to interact with the music. My Brother in law uses Light Show Pro but his tree does not sync to the music as well as the LOR and the Super Star software. I do not have any exper. with LSP so someone else my know more.

 

Hope this helps.

 

Happy New Year,

 

Lee

I'm still trying to get my head wrapped around the hardware part of RGB pixels but on the software side SS part of LOR S3 does a really good job and if you haven't yet you might want to check out nutcrackers effects and it will import into LOR and does some really neat effects

yea ive been trying to wrap my head around nutcracker as it seems to be the cheaper choice than madrix...though it is a little difficult at first ...but it seems to be OK.

 Nutcracker is free and is great in what it does, but as of yet it will only sequence RGB and is not a complete sequencing software. It will however export to almost all of the other sequncing softwares

Ernie,

 

I am working on putting together a package deal for mega trees.

It can use use the pixel strips or the pixel strings.

 

Still working out a couple items, but should have a product in a couple months.

I will let you know when I have it complete.

I am also geting up to speed on the RGB stuff as I am looking at doing a new RGB mega tree this year hopefully.

I have decided on using the J!Sys ECG-P12R that Lee is using along with ws2811 5 volt pixels for the tree as I have also read that people had quite a few failures on the 2801 pixels.

 

I looked at a new software this morning called HLS that you might want to consider too.  it is made by a guy named Daivd Hinkle.  You can find info on it over on the DIYChristmas forum http://doityourselfchristmas.com/forums/forum.php .  I downloaded the program (it is free) and was playing with it for a bit.

You will see a catagory for him down the page.  The program looks very promising and he is incorporating many features just for RGB.  There are videos you can see of it and it looks pretty wild.  It may tend to become the premiere program for pixel programming if he keeps at it like he is!

 

Some of your questons on power will depend on how you are going to hook up your strings to the controller as well as distances.  I do believe but don't hold me to it, is that the ECG-P12R will power a pixel string the lenght you are going to use directly through the controller so that you will only need the cable from the controller to the string.  If so, you might be able to just just some of the 4 conductor cable from Ray to feed the strings.  Although you may need to inject power depending on what chip protocol you end up using and the lenght of the strips.

There is a lot of good stuff over on the Australian forum http://auschristmaslighting.com/forums/ on RGB as well as power requirements and cable sizing.  It does take some calculating to make sure that you end up with the correct amount of power to feed the strings and make them light right to do it the right way.  Not that it is difficult but more that it is the right way to do it rather than just to say use this size wire and you could end up either using wire that is too small or is too big and wasting money.

Check twice, cut (or in this case) buy once!!

Minor point but HLS is Joe Hinkle's.
