View Full Version : Holdman Star My Way

First thing I did was check other peoples websites and this forum for info on how to make the Holdman Star. I wanted to do my own spin so decided to do a regular star shape with c9Ďs and Miniís. My original idea was inspired from both Holdman and http://www.fantasychristmas.com/project_slideshows/TwinklingStars/index.html

My Parts List:
1) 1X Plywood 5/32 Sheet of treated ply (Home Depot $26)
2) 3X sets of 300ct Icicles (Home Depot Sale $0.75 each)
3) 2X C9 strings (Home Depot $1.50 Each)
4) 1X Strobe (CDI $5.20)
5) 4X Black spray paint (Home Depot $0.99 Each)
6) 1X Drill Bit (I think it was 5/16 Home Depot $2.43)
7) Primer (already had)
8) Drill
9) Sander
10) Jigsaw
11) Measuring and Marking Stuff (Rulers, Pens, String, Tape Measure, Pencil)
12) Time = 5 Hours (not including drying time)

Step One: I made a template in publisher using the clipart and the custom page feature I decided to go 4ft X 4ft which worked out to be around 30 pages of paper. I hated to waste the paper but it was free Vís buying a projector to trace the image. Once printed, taped it together, cut it out, then laid it down on my plywood where I traced the outline with a ruler. This saved me a bunch of time rather then figuring out the correct angles and lengths.

Step Two: Cut it out. I had a friend come over to help hold it for me while I cut out the star. One thing to remember here is it does not have to be perfect because it will be on the roof painted black. I took extra care to make my points really nice and it really was a waste of time.

Step Three: Measuring it. To make it look symmetrical I divided the point with the mid section of the star to get the ratio of the lines which allowed me to make it look true on each line of lights. All I did was halve each point all the way through the star to find the center then measure from the center out (on each line) to figure the ratio.

Step Four: Marking the star. I marked the star with the shorter lines center out running one inch spacing for the longer points I think it figured around 2.5 inches (remember to use your own stars ratio to figure this)

Step Five: Drill out the C9 bulbs. On my measurement I ran around 9cms spacing per bulb. So I put one on each point and in the mid section then ran an additional 8 bulbs around the outline of each point. Using my ĺ inch bit it worked out well with a nice and snug fit through the 15/32 ply.

Step Six: Marking the Miniís. I used some string to figure the bulbs per line, it was so close to 900 bulbs at one inch spacing thatís what I went with.

Step Seven: Drilling Out and Sanding. I cant remember the drill bit size I used, it is large enough to fit the whole mini through the hole. I did end up buying a new one for this project after a few hundred holes. One thing here I would recommend is taking your time. With the cheap plywood I tore up the back side of the ply with the drilling. When done take the time to sand it off really well and re-drill as needed.

Step eight: Painting and lights. My first major mistake was to brush on primer. This caused the smaller mini holes to be clogged, after realizing my mistake I went to the store to get some black spray paint which worked out really well. I actually had to re-drill most holes quickly before repainting. When dry I mounted the c9ís then the outer line of miniís. To make sure I had everything right I used a pencil on the back and ruled out the areas for the different channels. Using pliers I pushed each mini in, I broke about 5 bulbs and had to re-drill a few more. At this point I was well over the star project after 900+ individual bulbs.

All in all it was a great project that will create great effects with the five channels.
My channels are:
1) 300 Minis Inner Star
2) 600 Minis Outer Star
3) 25 C9 Outer A
4) 25 C9 Outer B
5) 1 Strobe Center (Not shown in pictures)

Looks great. I like how you did your own design and combined the mini's with the C9's. Well documented too with lots of good pictures.

We are in the process of building our star, we are using 3/4" plywood and running into some issues with drilling out the correct hole size in order for the c9's to screw in.

How are your mini's held in place? Are they simply wedged in the hole? or did you have to glue them in somehow?

All I can say is WOW that's awesome!!!! Love the way it looks.

Wondering if it at all could be made to be collapsible for storage purposes, hmm...

Great job! :)

I wedged the miniís in with pliers. If you ďream-outĒ the holes it works well. I ended up running the drill in and out 5 Ė 7 times for each individual hole to make sure it was well drilled. As for the C9ís some were a little too snug so I fashioned a hone with an old drill bit, plastic bag, duct tape, and sand paper. You put the drill bit in the drill, tape on the plastic bag, wrap it around to snug, then tape the sand paper (rough side out) to the bag, use this to hone out the holes. You can go in and out of each hole a couple of times to make it a little wider.

Wow, nice, I can only imagine the sequencing possibilities if each layer of the star was an individual channel. Or if each light was an RGB node, The MrPackethead Star!
