big project starting

Big flexible strip Matrix project starting.
Note the picture - my current plan is to use this Black Snow Fence material to hole my 5 meter flex strips.

If you care to count, there are 34 horizontal segments to the fencing. I plan to attach 32 flex strips across, using occasional tie-wraps to keep it in position.

For stability, I plan to have vertical runs of 1/2" PVC (7 or 9, probably), to give it some rigidity, but still allow the entire grid to be rolled up for storage.

I'll add more pictures as I continue.

that looks amazing. what will the pixel node dimensions for this matrix? I assume you are positioning it horizontally?

Does xLights/Nutcracker work for it?

thanks

150 x 32 is what I have.
4800 pixels. Horizontal.

That looks like a great material for a matrix structure. 

I am curious how well the strips will hold up to being unrolled and rolled up each year.

I won't roll it tight like a sleeping bag because the strips might not like it. For long term storage, I plan to hang it in my shop by the PVC supports instead of it lying flat on the ground. I decided to use this mesh to reduce weight for portability and hopefully lower wind resistance (definitely better than a solid sheet of plywood or plastic).

Just a thought, you might try a cardboard carpet tube (they have various diameters) as a core for rolling your matrix up.  Then suspend the tube from the ceiling.

I can't wait to see it when it's done. That's going to look pretty sweet.

Kinda makes what I was planning look pitiful LOL


I want to make a matrix above my driveway using 4 meter strips X (11)


Good luck I will be watching to see how it turns out.

Measure twice, cut once.  Did you know that 5 meters is a LOT longer than 16 feet?
My garage door is just over 16 feet wide and this matrix was to fit easily inside it. Turns out that a 5 meter flex strip (150 LEDs) is 21 or 24 LEDs wider than I need. So my matrix just shrank from 150 wide to either 126  or 129 wide. Still pretty wide.

So, the picture shows the basic materials (black snow fence, 1/2" sch 20 PVC, and the garage door).
There will be 7 PVC rods hanging vertically from hooks in the garage door frame. The snow fence will be tie-wrapped to those rods. The TM1809 flex strip will be attached horizontally on each "rung" of the snow fence.

So tonight, the snow fence is cut. Tomorrow and over the weekend, I'll get the PVC cut and hung, then attach the snow fence, then start putting strips across. A shame I'll have to cut the flex strips, but I knew 4 meters was too short (barely more than 13 feet). I'll consider splicing together some cut pieces for another row or two of lights. Current plan is 32 rows because it is perfect for two Falcon 16s. 

For the Academy (July 12 to 14), it will definitely just be 32 rows though.

Before it gets too hot - (may get to 105F), I got the mesh mounted and hung.
Flat black paint on the PVC, cut in half at 5 feet, in case I want to add more rows later. :)

Small eye bolts into the garage header. Wonder what the neighbors are thinking?

Only two weeks until showtime.  Don't let a little heat stop you now!  That should be quite a challenge to get to the acadamy.
I definitely see the matrix expanding all the way down to the bottom of the garage door in the future.

Your neighbors are probably thinking something similar to mine when I was hanging my window frames on the house about a week ago. ;D

Much cooler day today (even though I had to work).

See the video and see how work is progressing:

I'm afraid this matrix will be "see me from space" bright.  Sean/Dave - I need an "Intensity" control in Xlights/Nutcracker.

I was initially concerned that the Horizontal distance between pixels was much closer than the vertical distance, and would make text and graphics distorted, but it is very "square" and won't be a problem. (you can easily see it at the very end of the video)

If you check, you'll see that I have changed my mind (again) about this super wide display.
While impressive, it was too "short" for good graphics. Perfect for long text, but that wasn't my biggest planned usage.

Check my new thread - I'm re-arranging to a 72x54 pixel shape. Nearly the same number of pixels but it is a classic 4:3 ratio for video.

I'm also looking at "magic numbers" for a more 16:9 approach for widescreen video, but 4:3 is actually a perfect match for what I have on hand.

A 16:9 setup just doesn't give me a perfect match, but 81x46 would be my likely choice. Since 80x45 would be an exact 16:9 ratio, just bump it out by one pixel (to be a multiple of 3 for cutting the strips) and add one more row to make it an even number (since I'd want to double back the strip to use half of the Falcon 16 control channels. This actually looks very promising in the Nutcracker viewer. :)

Or - to avoid the problem/hassle of doubling back on the 81x46 dimensions, it would be easiest to just add another Falcon 16.

With 11,178 channels and 3 pixelnet universes -- won't you need (3) Falcon-16 in any case?

Steve; at the academy , jon had 32x126 = 12096 channels. He drove these with two falcon boards.

The falcon-16's can drive 16x170 pixels (8160 channels per Falcon-16).

If  jon builds 81x46 he could use 23 strings each 160 pixels long folded in half. he almost certainly would have to do power injection

so, although he could use 2 boards, it would probably be easier to do 3 boards and have 46 strings of 81, no power injection needed.
