Music Selection

Music is definitely the heart and soul of a Christmas display. Back in the old days, even before home based computer controlled lighting existed, I would create a selection of songs to play in the yard for my display. Back then, the music wasn't played from a CD, computer or mp3 controller, but a 12 minute looped cassette. The selection included a few Christmas classics, which helped set the holiday mood and brought the simple static display to life, giving it a soundtrack.

Nowadays, music is the driving force of the display. It sets the tone, tells a story and creates emotion. Each year around late Spring or early Summer, I choose the music for the upcoming holiday season. I search my large collection of Christmas songs, as well as comb through the iTunes music store, looking for something new and different. As I listen to the songs, I try to envision the lights, animatronics and video interpreting and supporting the words and music. My selection usually begins with some type of instrumental or lyrical overture, followed by a selection of up-tempo songs with lyrics. I always like to include a slow meaningful song that draws upon the spirit of the holidays, family and memories. It provides a soundtrack to some family photos or home movies from days gone by. To me, this is very important, and helps to bring some real emotion to the display, connecting the viewer to the warmth of their own Christmas memories. I close the display with an up-tempo grand finale and holiday sendoff. 

My shows run approximately 9-10 minutes. I find a full song to become very repetitive, especially for a synchronized light routine, so I edit them down to 1-1.5 minutes in length. This helps to move the show along, keeping the lighting and supporting elements fresh and unique. My goal is to seamlessly connect the songs together, creating a continuos show, which flows from song to song. I sometimes use instrumental elements such as cymbal crashes or swells to help blend the songs together or emphasize a moment.

A few years back, I introduced an animated character to my show by the name of "DJ Jingles." He appears on video as the show's emcee, spinning the hits and introducing characters such as "Frosty" and the "Holly Jolly Dancers." He's become the perfect character to greet the guests and keep the show rolling right along. 

When I program my songs, I listen for the beat, but I also pay close attention to the melody. It's very much like editing a music video. The video is often cut to the beat, while there may often be moments in which a shot is held for a period of time, allowing the viewer to register the action or content. There are also times when the music is slow, calling for dissolves between shots or dips to black, creating some emotion or drama. These video techniques are similar to the techniques used in the sequencing of the lights. The tinkling of piano keys can equal the twinkling of lights, or a guitar rift can translate the chasing of lights across the yard. Musical builds can also be conveyed by raising the intensity of the lights followed by a flash of strobes. Check out my collection of display videos to see how I translated some of my favorite Christmas tunes into a multi-media holiday show.

Transitioning to LED lighting

A few years ago I discovered that LED mini-lights, in my opinion, had finally surpassed the visual quality of incandescent mini-lights. The intense color and brilliance of the 5mm LEDs as shown above, are very impressive. They are full wave, which means they will fade on to off smoothly over the full range. Their energy efficiency also allows for more lights per controller, as well as the potential savings on the holiday electric bill.

I started my LED transition in 2008. My display contains five colors of lights; Red, Green, Yellow, Blue and Clear, so a full transition would be very costly. I decided to first change my Z-Tree over to LEDs. The beauty of these lights is that they blend well with the existing incandescents. They're much brighter and colorful, but they still have similar characteristics. Last year I converted over another 1/3 of my display, this time changing my mini trees, roof line, wreath and a few shrubs. This year I hope to finally complete the transition to LED.

Simple Snowflake roof stand

In 2007 I added a combination of sixteen large (31') and small (21") illuminated snowflakes to my rooftop, powered by one sixteen channel controller. They were a great addition, and also added some extra height to the display. 

The problem was, the roof has a very shallow pitch, which means the snowflakes could not be seen very well from the street when laid flat on the roof. The solution was to create simple wooden stands to elevate them. Two different size stands were needed to accommodate the large and small snowflake patterns. I was able to make them very easily and inexpensively with some 1 x 2s, drywall screws, cable ties and Black paint. 

First, you need to determine the pitch of the roof so the snowflakes will stand straight up. This is easily accomplished by laying a small scrap piece of 1 x 2 on edge on the roof running top to bottom. Place a level along the 1 x 2 and mark a level line on the board. Cut on the line and save this as a gauge for use in the construction of all your stands. 

Notice the dimensions on the attached photos. Both the large and small stand dimensions are included. Cut the stand pieces, and don't worry if they are exact, or if you need to shorten one a bit to accommodate your wood supply. The upright and it's brace contain the angle determined from the roof gauge mentioned earlier. Use the gauge block to mark the necessary angle for cutting. 

Layout the boards as seen in the photos. Drill some starter holes with an 1/8" drill bit, and then drive some short 3/4" drywall screws (locations marked with triangle and dashed lines) to attach the pieces together. Next, prime the stands with some outdoor rated wood primer, and then paint them with a Black outdoor latex paint. The large stand upright almost runs the full length of the snowflake for support, while the short upright stops short of the center opening on the small snowflake.

The snowflakes are easily attached to the stands using large cable ties. Place the snowflake against the stand, centering it over the upright. Be sure to allow enough space for the power card to exit at the bottom of the snowflake. For the small snowflakes, three cable ties, top, bottom and centered, should be enough to safely secure it to the stand. For the large, four cable ties spaced equally across the upright should be sufficient. Wrap the tie around the snowflake center's rope light, and around the 1 x 2 and snug up the tie, leaving the coupling along the back edge of the 1 x 2.

I found the simplest and cheapest solution for securing the stands at the landscaping department of my local Home Depot. I bought concrete scalloped curved edging to hold the stands. For extra safety, I also purchased some Black nylon twine to prevent the assemblies from sliding down the roof. I attached the twine to the stand and block, and the secured the other end to a secure structure on the roof, such as a vent pipe or chimney. I lay the curved landscape edging over the center rail, one for the small stand and two on opposite sides for the large.

Shimmering Z-Star

I often get asked about the star which tops my Z-Tree. I created it using Silver Coroplast (CP) and a clear set of chasing or multi-function mini-lights (140 ct.). The three dimensional star measures 26" tip to tip, and it's supported by a threaded rod that is attached to the top most section of the tree.

The star is made from 4 individual cut pieces of CP. Two pieces are joined together with Duct tape. A duplicate assembly is created for the face and back of the star. These two assemblies will later be joined with small clear cable ties. First download the pattern pdf and print it out.  Cut out the large and small star point patterns. Using the Layout Pattern guide, build the layout pattern 1 and 2 on the Coroplast by tracing the cutouts multiple times with a marker. As you trace the pattern, mark the bulb holes with a small nail or pin. Remember to only do this for the star face only. Cut out each layout pattern from the Coroplast.

Next, 140 holes need to be made in the face half of layout pattern 1 and 2. Use a 3/8" masonry bit, and drill through the Coroplast into a scrap piece of wood at the points marked on the pattern. A mini-light bulb should fit snugly into the hole.

To eventually join the front and back star halves, you will need to poke small holes along the edge on the face and back at the marked pattern locations on the full assembly guide. Stack both the front and back layout pattern 1 in one group and front and back layout pattern 2 in another group. Using a small hole punch, punch through both pieces at once. The hole should be big enough to eventually thread a small clear cable tie through to join both halves together.

On the full assembly guide, notice the cut lines and the score lines. When cutting and scoring, use a straight edge and a sharp utility knife to carefully make the cuts. Tape the sections as indicated on the pattern at the proper locations with duct tape, and begin folding the CP to bring the edges together. At this point, the three dimensional aspect of the star will begin to form and the star face and back will no longer sit flat. A center hole can now be drilled in the front half.

Randomly insert the lights through the CP. Small pieces of tape on the back side can be used to keep the lights in place. Test the lights and adjust the speed control to the desired shimmering effect.
A 12" length of 3/4" strap iron is used to mount the star to the tree. Drill three 3/8" holes, two - 1" in from the ends and one centered on the strap iron. Bend the bar into the shape as seen in the picture. Begin with a big "U" shape, and then flare out the ends to meet the star's large side tips. Mark the  locations of the end holes onto the Coroplast, which should be the back of the star, and drill it with the 3/8" masonry bit. Next, attach the threaded rod to the center hole of the strap iron with two nuts and two lock washers. Be sure to tighten the nuts as much as possible to prevent the assembly from loosening up and twisting. Mount the strap iron to the back of the star with two 3/8"x 1/2" pan head machine screws. Use washers against the screw heads to prevent it from ripping through the Coroplast. The bar should be centered on the bottom tip and in the same position as the picture to the right.

Now it's time to join the front and back together. Line up the sections and carefully tuck the wires inside. Start threading the cable ties through the front and back holes and snug them tightly. After all the cable ties have been placed, clip the cable tie tails as short as possible.

This completes the assembly. As most trees differ, you will need to mount the star to the top of your tree using your own method of attachment.
