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.

  • 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.

PLEASE HELP!! Blue LED's flicker when fading....but not all???

Recommended Posts

Im running a few test sequences when I noticed one of my Xmas trees flickering during all fades. All the other LED's Do fine. Its just the one tree. Anyone know what causes this?

UPDATE>This is what Ive checked out so far. Firmware on that controller is 4.40. I made sure no Cat5 cables were crossing anywhere around the tree or controller. I made a sample sequence that was just a bunch of fades. I thought that while the tree is fading I can unplug a strand at a time to see if all strings are flickering or was it just one string that caused the whole tree to do so. No luck. I plugged power into the top string only...it flickers. With that one still unplugged, I plugged into the rest of the tree...it flickers. The 4 other Xmas trees, the Mega tree etc. fade great. Not sure why this is the only part of the display doing this. Oh and there are white minis and red LEDS on this tree as well, but only the blue flickers.

Sounds like you need a "snubber"...

(some LED configurations need it... others seem to do OK without it)

If you have a glade "plug-in" around anywhere it will work in a pinch... just plug it into the end of the strand or channel giving you issues and see if things smooth out.

I just looked at the channel property grid to see what else was plugged into that controller. I have 5 Xmas trees in the display each has white minis, red LED's and blue LED's. 3 out of five trees are plugged into that controller. Two trees work perfect but the blue on one tree doesnt. Am I missing something?

I actually use the plug-ins myself... they are water resistant and don't create any problems.

The other option is a 1/2 to 1 watt 47k to 56k ohm resistor attached across the prongs of an AC replacement plug and then covered with the shell for safety. (there is thread about this in this forum from a while back)

Glad to hear it helped! :)
