16x48 Pixel Matrix Display

This started as a kit from Seasonal Entertainment, which was the power supply, controller with box, pigtails, and (16) 50 count 2811 Pixel strands.





* Three panels, each 44.8 x 46.3 outside diameter
* 2.8" center to center spacing. The spacing was expanded to provide a .15" hole to frame gap to allow for the a joining panels but you will need to confirm that this is sufficient for your pixel type.
* 3 panels
* 1" mounting braces
* 16 pixels high by 48 pixels wide
* Overall size will be determined by pixel spacing and mounting braces.
* Pixel hole size OD is .5"
* Frame and cross support size of 1"

Here are some closeup pics of the panel.

Backside, holes were the same size as the pixels, so I needed to run duct tape on the back and slit with an x-acto knife so the pixels would stay put.

Edge, strain relief and pigtails for easy connections.

Candy Cane Pixel Arches


YouTube Video of the Building and Testing of the Candy Cane Pixel Arches:

A test set of nodes. The box is a CG1500.
Back side. PVC has been glued to the center spokes for stability and provide a way to hold the rebar.

Notice the way the nodes are sitting in the candy cane.

This is my configuration on the controller.
Unmodified Candy Canes, and a few pieces of Rope Light Spool, cut in half.
When building these, you will want to use the white candy canes, as the other colors will filter the light from the pixels, and not give you the same results. The hub the canes are mounted to, I used LED Rope Light Spools, and cut them. This pic is from another Light Show Enthusiest (Carlos Barreto), as he is prepping to design his version of Candy Cane Pixel Arches.

First, remove the caps on the candy canes, and pull the incandescent bulbs out. Lay the canes into your arraignment, and use white zip-ties to hold opposing canes together. Next, the threading of the lights. 
How to thread pixels into the candy canes:

Use a squirt bottle with a soapy solution (Dish Soap), about 10 squirts into he candy cane, and pull the pixels through with string. Lay the wire flat along the nodes, and guide them in one at a time.


Once built, the channels need to be built into LOR so you can sequence them. Here are some charts I made to help with the programming and planning for effects.

These are the WS2811 Pixels. Not the exact same ones I used, but these are the better versions. 3 wires instead of 4, and the same size.



I am sharing the Macros I have developed for various effects, to include the sequence for the song here. This is "Dueling Jingle Bells" performed by the US Navy Band.
