Thank you for your interest in my Christmas light show. For 2008, we will continue with the show we had last year.

Current status
The light show is equipped with Ground Fault Circuit Interrupts (GFCI) for safety. If the ground gets wet and some of the power starts to go where it shouldn't, then the show automatically shuts down. It won't come on until the ground dries out and I reset the GFCI.

This is of course inconvenient if you want to come out and see the show. Therefore, the system will test the GFCI every few minutes between 5 PM and 10 PM every night and post the results here. That way, you can just check this page to see if the system is up and working.

Directions
If you want to come and see the show, it will be running from Dec 1 through Jan 1. Our address is 7730 NW 11th Place in Plantation 33322.

From the east, take Sunrise Blvd. 1.5 miles past the turnpike, then turn left onto NW 11th Place. Our house is the next to the last house at the end of the street.

From the west, take University Drive south from Sunrise Blvd. to the next signal, which is Marcano. Head east on Marcano to the stop sign. Turn left onto NW 11th Place and we are the 2nd house on the right.

Here we are on Google Maps

Once you get to our house, park in the driveway or on the swale. The music show doesn't run continuously. You have to push the green Play button on the control console by the sidewalk.

Optimal viewing
If you really want to have the best viewing experience, the best place to stand is on the sidewalk across the street from my house. It is difficult to hear the music very well from there. So I broke down and ordered an FM transmitter. You can bring your personal FM radio, stand across the street, tune to 104.1FM and rock out. I have some loaner headsets if you need them.

Videos
The videos are not as good as the live thing, but they do give you an idea of what it looks like. You can download the 25MB MPEG-4 movie file of the best song in the show which is new for this year. (I'm actually trying to produce a better video that shows some of the details, but that probably won't happen until Dec 16 2008.) You can also still download the 100MB MPEG-2 movie file of the show from last year. These files will play using mplayer on Linux, Windows Media Player on that OS from Redmond, and VLC on the Mac. If Windows Media Player doesn't work, try VLC on Windows. (If you still can't get it to work, you can view a low-quality version on YouTube. )

History
I started work on the project in February and built all of the hardware and wrote all of the software myself. For engineers and geeks only: I have a technical page on how it was all done, plus a HOWTO on computerchristmas.com which is where I got the design for the main controller.

In December 2005 an engineer friend of mine showed me a movie of another house that had done this, and that is what inspired me to do this project. This video blew me away when I first saw it, and I thought to myself ... Wow - I would like to do that ... I think I can figure out how to do that ... I KNOW I can figure out how to do that ... You can download the original movie, which is of a house up in the Chicago area.

About
There are about 2400 lights on the eave of the house. There are 16 segments, each of which has 3 strands of lights, 50 white, 50 red, and 50 green. There are probably about another 5000 or so in the yard. As far as big yard displays go, that isn't a really big number. I use the computer control to get more "Wows per Watt" - and therefore it's good for the environment. ;-)

There are 96 different channels of control. Each channel is one string or a set of strings of lights that can be turned on and off independently.

The music plays automatically every half hour beginning at 6:00PM and ending at 10:00PM. If you want to play a song on demand, there is a user console next to the sidewalk with two buttons. The orange button lets you select which of the three songs you would like to hear. When you press the green button, the song will play immediately.

Here is a picture of the control panel.
