StarBurst

Pixel Starburst Rainbow

Introduction

A pixel StarBurst added to your display adds a lot of possibilities for effects. You can use any of the Nutcracker effects built in to xLights, Vixen 3 and soon other sequencing software to easily add exciting movement to this prop. With the addition of a lighted post, you can create an effect that looks like a firework being shot into the air and exploding.

The pixel starburst we're going to make has 8 spokes that are 32" long. Each of the spokes has 22 pixels on it for a total of 176 individually controlled light points. This demonstration will show it connected to an E682 by SanDevices, but it could just as easily be controlled by any of the pixel controllers out there.

Materials Required

Below are the parts required to make a StarBurst. If you're making more than one, just multiply the quantity by two. Where possible, I've linked the BOM to outside sources to help with understanding what all the pieces look.

   - Qty. 2: 1/2" PVC Cross 
   - Qty. 3: 1/2" 10' PVC Pipes
   - Qty. 1: 2.5" #10 Machine Screw
   - Qty. 1: #10 Nut
   - Qty. 1: 1.5" Screw (any screw will do)
   - Qty. 2: Pixel Strips (30 pcs/meter 30 ICs/meter)
   - Qty. 1: Waterproof Pixel Power Connector
   - Qty. 1: Tube Clear Silicon Caulk
   - PVC Glue (Clear Recommended)
   - 20ga Blue, Brown & White Wire (you can use whatever colors you want)
   - Zip-Ties
   - Blue Tape (not required, but helpful)

Tools Required:

   - Saw to cut PVC
   - Scissors
   - Wire Cutters/Strippers
   - Soldering Iron
   - Solder

Build Notes

   - This is now I make my starburst. It is not the only way and it is not the right way, it is just my way and it worked great for me.
   - Use at your own risk.
   - I would suggesting making all of your wires at least 1" longer than mine. Better to be long than short.
   - Get high-quality zip-ties. The ones I used were brittle and I know at least a few will break every year till they are all replaced.
   - I used wire colors based on the waterproof leads I have. You can use whatever color you want. 
   - The colors I used on the leads may or may not be "standard". I have standardized on blue for +V, brown for ground and yellow for data.

PVC Frame

The PVC frame is straight-forward and easy to build. You can make yours any size you want, you'll just have to adjust your measurements here and in the following sections to account for the size difference.

Single Spoke Measure

1. Cut 8 PVC pipe lengths to 32".

Double Spoke Measurement

2. Glue them into the 2 PVC crosses to make two 4 way crosses that are about 66"-68" across. 3. Drill a hole through the middle of each of the PVC crosses using a .201 or #7 drill bit -- anything close will do.

Hub Measurement

4. Attach the crosses together with the 2.5" #10 machine screw. Use washers on either side if you like. 5. Align the spokes evenly with a protractor or by measuring the outside tips of the spokes to make them even.

Hub Attachment

6. On the back of the frame, drill a starter hole for a screw so that it will hold tightly to the hub. This screw will keep the frame nicely positioned so the two frames will not turn. Take a look at the picture. I'm having trouble explaining this in words.

That's it, your frame is completed.
