I want to build a matrix as big as possible.

I am thinking of using 12, 13 or 14 pixel strings, I could maybe add 10 or 20 pixels onto each string but I want to keep it as cheap as possible.

I am using 5v pixels, and I will have plenty of pixel outputs. I was going to do 2 strings per output, but all my controllers allow more.


I worked out that 50 pixels with 5cm spacing between each one would make the matrix two and a half meters, which is around the size I want, but will 5cm be too much of a gap to make the image viewable?

Here is my website and you can see in most videos how close the pavement (Sidewalk, as you Americans call it) is to the house.
Also the matrix would be at an angle.


I also want to know the easiest and best looking way to build it. The matrix that I built for this year looked OK, but was a tiny bit messy in the daylight and there were a few holes in the wrong place. You can see it up close in one of the scrolling images on the homepage.

I have heard about strips and nets but HolidayCoro shipping to the UK costs over $1000 for an item less than $100!
I looked at Boscoyo Studio strips and they look good as well, but are strips a good way to build a matrix?

The Boscoyo strips can be used in a matrix build - I don't recall who but I've seen pix of a setup done by mounting the strips to a PVC frame. The strips can be cut down from their 8' length so you can make them any length. Of course the resolution will not be as good as what you can attain with regular pixel strips or P10 pixel panels but it would be probably be cheaper and easier to maintain. Both the strips and especially the panels require a bit more care wrt to weatherproofing.

I would use a sheet of 1/4 inch ply and drill 12mm holes for bullet node pixels. Here is my 200 pixel matrix that I built using 1/2 inch ply with 200 holes drilled into it.
yes it took some time but everyone liked it. I will be going bigger for 2017, I painted mine black and made sure there were no extra holes, I took the time to use a square to get straight lines and keep every pixel inline at a 1.5" spacing from about 5 meters away,
the video is not the best but I recorded it on my iPhone.
I can take a picture for you sometime this week and show you the panel during the day

This:

5cm is ~2 inches. So order the 2" mesh.

Its flexible which means you can roll it up into a tube for off-season storage.

Alternatively, James has pixel strips with holes every 1". You can decide on 1", 2", 3" or 4" spacing using the same exact strip. The downside is you will need to have horizontal strips too to form the grid. I think the coro mesh is a good way to get it up and running easily with minimal putz factor.

You could order a few of James' strips (he delivers fairly quickly). Then set up a small test patch to visually see what 2" or 3" spacing looks like. And then order the mesh from coro in whichever you feel you want yours to look like. And then you still have the strips for other experiments and projects.

The problem with all the strips and nets are shipping to the uk
It's expensive and that's for small packages too.

Well, you are an island. Not much you can do about it.

Got a friend with a laser cutter? He(she?) could probably cut you some matrix or strips out of an abs sheet pretty quickly. At least some small samples to test your grid size out on before you see how much a big mesh would cost to ship.

Hi, why not just go for WS2812 strip at 150 LEDs per meter.

http://www.ebay.co.uk/itm/5M-5V-WS2812B-WS2811-Individually-Addressable-5050-RGB-150LED-Strip-Waterproof-E-/171893269284?var=&hash=item2805a32324:m:maCnR0wfI9HYyddJSkHSYdg

At 150 per meter they are 33.4mm apart, that will give you a good resolution. If you want to keep your 2.5M form you can just cut them in half and have 75 LEDs per strip. At this price you are looking at 10 / strip of 75, so 120 to 140 for 12 to 14 rows (900 to 1050 pixels).

Ideally if your using 33.4mm horizontal spacing you should use that vertically as well.
12 strips * 50mm = 600mm / 33.4mm = 18 strips which would be 180 (1350 pixels).
14 strips * 50mm = 700mm / 33.4mm = 21 strips which would be 220 & one spare strip (1575 pixels).

No holes to drill, just stick them on a board of your choice. They will mount flat to a wall (no wires at the back) & waterproof. On the down side the will need more power and controller capacity.

EDIT:
Typo: At 150 per meter they are 33.4mm apart
Should read: At 30 per meter they are 33.4mm apart

looks like 150/ 5 meter

Yea, the densest I have ever seen is 144 LEDs/Meter.

Hi, sorry typo & yes I have some 144/M, made a clock out of them http://www.thelightclock.com/ (used an ESP8266-01).
Typo: 30 per Meter * 2.5 Meters = 75 LEDs.

I made my Pixel grid from WS2812B IP67 30Pixels/M
I got 1500 Pixel for 150, So the pixels for the grid cost about 75
I mounted them on 25mm Sq/Chicken wire.
I cut the strips to 2M, rewired and sealed the ended.
I have 12 Lengths = 720 Pixels. (I wish I had done a few more.)
So the grid is 2M x 0.6M, But it looks very good at night.
Wove, them in and out of the 25mm square grid.
For the vertical spacing, I used every other square, so 50mm Spacing.
Its powered by a 5V 40A PSU and run by my own ESPixelstick.
I would guess it cost about 115 (170USD) to build in total
To make it look neat, I put black fabric mesh over it, it looks completely black in the day and the LEDs shine thought it great at night. (And in the day!)
Hope to post some pictures of how I build it, when I take it down in a few days.

EmmienLightFan? You do not show a location, are you in the uk?

Strips from Boscoyo worked really well for my matrix. Super easy to build the matrix and as someone else mentioned, easy to roll up and store in the off season.

Thanks. I think that I am going to do this.

I am getting a Falcon controller, and I think that it can have different pixel types on each output (Can it?) so I can use these strips as well as my WS2801 and WS2811. Thanks.

If you are talking about a F16v2, i beleive it does. Although the F16V1 & F16- Beagle Does not. But I do not own any Falcon Controller, So I may stand corrected.

The f16v1 does support different types but not as any as the v2. The f16-B only supports ws281x and tm1804 currently. We may add more pixel types for the f16-B in the future but it is not a high priority.

F16v2 not only can have different types per string, u can mix types on a string. Dave calls that virtual strings. Example: string 1 - 100 nodes of 1804 , string 2 - 70 2801 nodes, string 3- 50 nodes of ws2811 flex, 80 nodes of 1804, 300 rectangular 2811. The 3rd string is a virtual string mixing different string types on one output

It looks like a really good controller, and with so many outputs, I will have room for expansion and I have my Pixlite4 which can be moved somewhere else to minimise cable runs.

Do you think that 4.2cm spacing between each horizontal line is too much? Viewing area is quite close, as can be seen in my pictures and videos.

EmmienLightFan,
I took my display down today, here is my wall grid.
Its 720 pixels of WS2812B 5V IP67.
12 x 2M Lengths
Power Injected at both ends.
Bus Cables 6mm2
Mounted on 25mm Sq Chicken Wire.
Supplied with 1x 5V 40A PSU.
Using ESPixelBug (Sealed in tape, top right.) with ESPixelStickk Code V1.3
This grid is wired Top Left to Bottom Right. This is not ideal, It should be Bottom Left to Top Right.
But it was easily corrected in Vixen Setup.
I cover it with a Black Fabric Mesh to tidy it up.

Yes, I am in the UK!
Your matrix was the look that I was going for.
So your matrix has 12 horizontal lines?
Sorry, I missed your post when reading through this. I was on my phone.

Very nice. How many vertical lines are there?

Also I saw some 60 LED per meter strip in Ray Wu's store, but it is a pixel data type that I have never heard of and apparently is a clone of WS2812B, but my controller's may not support it.
And the strip was 4m long, not 5m, so it would have to be 2m not 2.5m.
However I would have a 120x14 resolution!

What is the resolution of yours?
How much space is between each horizontal line and how bright is it? Did you need to limit intensity?
I am in the UK.
Your matrix is what gave me the idea to make mine.

As you can see on my videos on my display website (I think that there is a link in my forum signature), my house is close to the road. I am going to put my matrix on the sloping roof below the windows, and my snowflakes either side and if I get time some pixel circle outlines for the snowflakes.
Where did you get the chicken wire? I was going to use PVC pipe and a lot of T-Pieces to create a frame with 12 bars in the middle, and cable tie the strips onto all the horizontal bars, but this is expensive. Chicken wire is cheap and I could make a simple frame to keep it straight and hold chicken wire onto that, then hold strips onto that.

It is made from 5M Reels of WS2812B, you can cut and join as required.

12 Rows, 60 Leds per row. = 720 Pixels.

The led are 30/M so 33mm apart in the Horizontal and 50mm on the vertical.

I am going to buy strips soon. The EBay listing linked in this thread just ended and that was a really good price.
1050 pixels in strips, and 100 square nodes for the outline of my frame.

Here is my matrix 200 5v pixels spaced 1.5" apart in both directions. Text looks good for scrolling and other things look good :)
It's staying the same for 2016

I had a matrix this year. 288 5v pixels and 2CM spacing. I could have done much bigger spacing for a bigger matrix. The matrix looks like a white blob in most of my videos.
I had lowered the maximum intensity to 80% and it still was really bright.
I like the matrix very much. It will be used for Halloween and Christmas again, but only as a secondary matrix. I want something bigger and better with a much higher resolution.

My matrix actually looks very tidy when it is down. It is really nice, and fits some images (I make them in Photoshop) such as an Olaf, a present, a candle, a flame (Nutcracker fire effect with a teardrop shaped image as a mask).

I've bitten the bullet and gone for an 800 pixel matrix.
Have to make the frames and build the whole thing yet.
That's the fun of it though.
