Some Fast Technical Facts about our Display

Some of our display is static, meaning the lights stay on all of the time.  We happen to like the look of lots of lights on all at once!

We use four different computer/electronic control mechanisms to drive our display.  You can learn about them further down in this page.

Our display incorporates a video projector to show multimedia during the show.  Roughly half of our musical sequences have custom-edited video synchronized to the music and lights, specific for each song.  The other half of the songs incoroporated "speech bubbles" for our Linus Shares the Gospel display, which is one of our oldest and most unique displays, and for many years used a slide projector to project the "speech bubbles" to make Linus "talk".  Click Here to read more on the history of this display.

Finally, our display gets music from our own FM transmitter.  This transmitter broadcasts our lighting program from the computer which controls our lighting. 

How It's All Controlled

Our display is entirely controlled by computer.  We use several different technologies to control the display.  Click the picture or links below for more information on each technology.

Light-O-Rama ControlLight-O-Rama:  We use hardware and software products by Light-O-Rama to control most of the music-synchronized portions of the the display.   

Pixels:  Pixels are pretty incredible light strings.  Imagine a string of Christmas lights that you can not only tell each bulb individually to turn on or off at any given time, but also what color it should be, and how bright?  That's essentially what a pixel does!  We introduced pixels into our display with our newly redone Mega-Tree in 2012, and have added additional projects since.  We use controllers by SanDevices to control our pixels.  

DMX:  DMX is an industry-standard lighting control protocol.  If you've ever been to a rock concert, theater production, dance club, or stadium, you've likely seen DMX in action.  We use DMX to control portions of the display such as our North Poles, the multi-colored star on our Mega-Tree, the colored LED wash fixtures that highlight the front of the house in different colors, and the candy canes near the driveway..  We also use a variant of DMX called E1.31, which allows us to stream over 9 universes (4608 channels) of data from the computer to our pixel displays over a standard Ethernet connection.

Standalone ControlHome-grown Standalone Control:  This was our first foray into electronic control, and became part of our display in 1999.  This controller controlled our large Merry Christmas sign up through the 2007 season.  It was based around an Atmel AVR microcontroller.  For more information on this display, click the link above, and you will be taken to the Merry Christmas Sign page.
