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.

Cut off Switch

Recommended Posts

Has anyone ever created a cut off switch for there display? A switch that would be on some sort of sensor so that if someone were to be wandering around in there display all the power for the main display would go off and possibly then turn on security lights.

While I was reading another post it got me to thinking about that vast open area in our display that I don't want people to wonder thru. We are planning on basicly roping off the edge of the display so people know were not to go past. But there is always still that chance that someone might decide to wonder where they shouldn't be and inadvertantly put them in danger of all the wires laying around the voltage going thru them.

You'd probably need to use a hefty relay, or a whole bunch or relays on each circuit.

Maybe this is something you can do when LOR comes out with motion sensor control.

Yeah, a "soft relay" in the form of an LOR interaction would work well.

Not sure it's necessary, though. Just make sure you have a defined perimiter for your display. We used to use a candy cane fence, last year we switched to lawn arches. Since we usually have snow, and I always walk in defined paths around the display, I know if someone's been in the perimiter or not, and it almost never happens (the few times it has seems to be a kid posing for a picture just inside the perimiter).

You can do this with X10....

1 - Replace your normal outdoor outlets with X10 super sockets. This includes the ones that run your controllers. DON'T replace your GFCI's! Instead, add the X10 outlets downstream so you are still protected. Put all the outlets on a single house/unit code (for this example, A1).

2 - Add your security lights and place them on a separate house/unit code (A2).

3 - Mount as many X10 motion sensors as you need. 1 or 2 should do the trick. Be sure they are close to an X10 transceiver so they can wirelessly talk to it (A2 - so when it detects motion, the security lights immediately come on).

4 - Program a CM11A interface with a macro. Whenever it hears the ON command for the motion sensors (A3), send an OFF command to the Super Sockets (A1).

When someone comes into the yard, the motion sensors will send A2 on. This will automagically turn ON the security lights. When the CM11A hears the A2 on command, it sends back an A1 OFF to kill the show.

Result: Security lights on, show off.

My websites has a whole set of articles I wrote about X10 that may help.

Search ebay for Bussman Power Modules

On ebay there are two 60 amp models priced at $1750 but I found a like new, 100amp model last year on ebay for $40 + $50 shipping. Basically what it is is a large disconnect switch that can be thrown manually or you can wire a fire alarm into it and when the fire alarm goes off it will automatically disconnet the power. I think it could be easily adapted for your use.

I built a Christmas Train Display last year that needed two 30 amp circuits to operate the lights and trains.

What we came up with is a 3 pole 240 V 3 phase 60 amp relay with a 110V activation coil. I connected the two 30 amp circuits through two of the relay contacts and then used SPT1 wire connected to the 110V activation coil terminals, ran the wire to a standard wall timer and put a SPT1 plug on the end, plugged it into the timer and setup the timer to turn the display On & Off. I used a digital timer to program different times during the week.

You could use this concept but when a motion detector is activated the circuit to the coil is broken and the relay opens.

Was looking for a picture to show, this is a big relay and would need its own enclosure.

It worked like a charm for the 7 weeks the display was operating.

Using a small control circuit to control large power circuits is the way to go.

Just my 2 cents worth.

You can get a 3 pole 60 amp contactor at Grainger for about $60. That could shut off 180 amps of power at 120v.

Dennis , where did you get yours? It looks like were thinking the same thing.

I guess it all depends if you pull power from all over your home or you use a main breaker for your display, I use a 100amp 2 pole breaker for my show that goes to a subpanel on my porch and gives me 200 amps at 120v.

Mike that is what I used, thanks for the picture.
