  • Christmas 2017 countdown has begun. Most people reveal their displays the day after Thanksgiving. 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.
  • 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.

  • About my display
    16k lights with a mix of LED and Incandescant. Moving slowly towards having a full RGB LED based display.
    Being in Australia the majority of external lights are low voltage 24v/36v that I drive with DC.
    I run 48ch DC Controllers of my own design using DMX.
    2010 should see around 25k lights being put up.
  1. Aliexpress

    Oh seriously, Aliexpress has equal if not better protection these days than Ebay. Money is held in escrow. You control release based on acceptance of goods Dispute process is solid and works the big ecommerce sites will have a share of shonky sellers. With Aliexpress some extra due diligence checking product descriptions is a good idea.
  2. Okay...so I'm Lost...what's It All About?

    Yes it is, terribly over simplified RGB does not equal pixels. Pixels however do equal RGB. I did a RGB display in 2009 that never had a pixel in it and still use the same stuff.... it's what we now call dumb rgb. I do agree with the bottom line however and would add that in my opinion the best displays combine all lighting types to provide a balanced look. Pure pixel displays can look clinical and non Christmas.
  3. A Dirty Secret. Pixels Are Power Hogs.

    Louie is spot on, both with the original comments and subsequent real world measurements. The original post by Chuck has factual errors and should be corrected or removed. Pixels are not low power just because they are low voltage. Low voltage should not be equated to Low power Interestingly lets look at a one for one with Incans 20,000 incans = 200 strings @.3A-120v = 60A @ 120V = 7200W 20,000 Pixels, set to white, each pixel uses 60mA @ 5v = 1200A @ 5v = 6000W As Louie has already shown Pixels never draw anything close to the theoretical current and typically are half of it so the 6000W becomes 3000W in real life. Now lets take LED strings as used in the USA (to be fair to Chuck) Believe a 70 count string is 2 sections at 120V so 40ma nominal draw. 20000 lights would be 285 strings = 11.4A @ 120v = 1368W So one for one again normal 120v led strings are more efficient Now take the LED strings, multiple for 3 to get at least 3 basic colours and we have 60,000 leds to cover 20,000 pixels in colour ability for guess what... the same current draw. Want more colours... Pixels win the Power game.
  4. Online Mini Conference

    Gig, Thank you for providing these minis, great chance to bring otherwise disconnected people together. Got a little daunting with 40+ people today, i rely so much on seeing the audience and seeing when they fall asleep it was hard to know if people where listening. Thanks for the chance to pass on a little knowledge Cheers Phil
