  • 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.

Wreath I programmed using a Siemens S7-200. I cut a string of lights into 10 sections of 24 volts each to run off the DC power supply & the PLC's DC outputs. The outputs are controlled by a counter that counts up to 87 based on a timer set at 0.42 second pulses. Thsi entire project was completed in less than 2 days after I thought it up, although I have tweaked the program since the video was taken.

I came across another PLC identical to the one used for this wreath & decided to make another one - except I changed the new one to solid color sections instead of the multi-color sections of this one. Watch for the Wreath Ver 2.0 video when I finish it.
