    Default 3840 Pixel Matrix Informations

    Hello!

    I finally have posted pictures of the pixel matrix.
    3840 Pixel Matrix | Facebook
    I have lost the pictures I took when I was building it, but it was pretty straight forward.

    1. Sandwich 5 4'X8' pieces of Corrugated Plastic with a sheet of 4'X8' 1" pegboard on top.
    2. Place the pegboard in such a way that all 48 holes can be drilled into the Coro with the last hole as close to the bottom as possible
    (To leave room at the top to attach it to the house)
    3. Drill holes all the way through every other hole (2" spacing) Use a high quality drillbit that is sharp so yu don't have to clean the holes. Drill a 48X16 Grid
    Now, I chose this number because I could use 16 pixel strings from Ray Wu with 48 pixels in each string with a power supply at the E682 bard (no power injected
    down the line) and it was easy to create the matix in LightShowPro.
    4. Then, cut the grid from the rest of the Coro (the original sheets are 48"X96", new dimensions are 32"X96"
    5. Sandwich the top of the panel between 2 1'X2' boards. I predrilled the 3 holes and then used the coated Drywall screws with a washer on the head to secure them
    6. I started in the middle, I clamped the panel to the roof and when it was level I drilled 2 holes all the way through and attached the panel with bolts. Then did the same
    for the other 4 panels.
    7. The easy part was done! The hardest and most painful part was pressing the pixels through the coro.

    I used the flat WS2811 pixels from Ray Wu. I ordered 4 types of pixels from Ray back in July. My and my wife looked at each pixel. While the TS3001 has more levels of color, the Ws2811 were at least twice as bright, that was the selling point. As you can see, they are really bright youtu.be/ukASk78uJto These are the pixels: Aliexpress.com : Buy WS2811 LED pixel node, DC5V input, full color RGB string,50pcs a string,IP68 rated from Reliable ws2811 pixel node suppliers on Ray wu's store I do not like the cylindrical pixels. The cyllindrical pixels were easily pulled out of the coro (even just by brushing against it or wind moving the panel). And I only have 200 pixels of cyllidrical type and I have pulled the wires on 3 of them apart. I have yet to pull apart a flat pixel and I have much more of those. Also, It is easier to do a visual check on the pixel to make sure they are sealed correctly, or at least appear to be.

    I have to give a lot of the credit to Jim at Sandevices. I was originally creating a santa house: http://www.lightshowpro.com/lightsho...nta-house.html But when I went to him with E681 questions he asked why I was limiting myself to that particular shape. (of course I did purchase 4 more boards......) He showed me pictures of his lights and I was hooked. At the time he was using the pixels to display pictures. I figured that if I was going to do this I wanted video! It actually played an important part in the Live Halloween Show www.youtu.be/wITaUm0j_kw

    That appears to be everything. I am sure I am forgetting something.
    Let me know if you have any question and thank you for your interest!

    Some connection information:

    Each each panel has 16 strands of 48ct WS2811 pixels.
    Each strand plugs into a sandevices connection.
    They are powered by an on board power supply (pixels get their power from the board) no power injected down the line.
    Each controller is only using 2304 logical channels over 5 DMX universes (510, 510, 510, 510 and 264) well below what they are capable of, but this way each panel is its own setup and actually mobile. Which will help when Halloween rolls around!

    I have been reading through a lot of your posts, is there any reason you have limited yourself to 5 panels.
    I understand the bit about the 16 pixel strings on each panel. Is it only due to the size of the garage door area as I would love to create something a bit bigger for an outside display on the side of a building.

    No reason, just a guess. Lol!
    On hindsight I would have done a true 16X9 resolution, but honestly I wasn't even sure if when I envisioned was actually going to happen. And there is of course the down time between ordering and receiving. Don't get me wrong, Ray came through but a week before Halloween I didn't have my pixels yet! (Ordered in July, custom pixel spacing caused the delay). I mean I never start planning that far ahead!

    quick question...The sequence elements you used for the matrix...did you have a single element with all the pixels in it or did you break them out by controller board. I was one of the first buyers of Jim's boards and have been using them for years.

    I've got a mega tree project I'm working on and ran into a problem of trying to integrate EASILY all the channels into a single element called MEGA TREE. I'm using 3 of 6 E68X's on the mega tree. 2400 pixels. Any ideas? I would like a single element.

    Hello!

    I used 5 E682 boards and added them as 5 elements. Then I added all the elements to a layer and worked it like that.
    I know you could add only 1 board and change the 680 channels to create 2400 RGB channels in that board. Then in the network setup you would assign them to the correct boards/universes.

    I do know that when you export, LSP exports a "controller" at a time. One of my sequences where I had 5 controllers with 768RGB channels took a few hours to export. The sequence where I had one controler with 3980RGB channels exported overnight and after 12 hours was still exporting so I cancelled it....Just and FYI.

    Hope this helps.

    Thanks Eric

    I got an idea has how to fix the 'problem'...I'll truncate the length of the universes so that the physical RGB channels number of continuous...that way I can make a 2400 pixel (7200 physical RGB channels) element. This may have some advantages on the export issue
    Keep U posted

    I felt quite unpleasant at first because my search engine took me to this irrelevant content to my 2d matrix barcode generation using jasper search for my data matrix problem. Anyway, I fortunately found that the software here supported by this forum seems to be interesting, I'd like to stay here.
