    first small scale test of our 160x80 [Video] wall

    I used Paul's OctoWS2811 library. In it there is an example sketch for sending data from processing to the teensys.

    first small scale test of our 160x80 [Video] wall

    Hardware: WS2811 led strips (@ 60 LEDs per meter) setup in a 180x60 matrix 10 Teensy 3.0's connected to a Intel i5-4670K PC with passive CPU cooling (playa dust destroys fans) NVIDIA GeForce GT 640 (also passively cooled) ASUS Z87-K motherboard that has 10 USB2 connections (so I didn't need a...

    WS2811 on Teensy 3.0 using FastSPI_LED library

    I used a high temp hot glue gun (I think it's 80 watts) on 3/4" birch 5x5 plywood sheets without the silicone covering.

    first small scale test of our 160x80 [Video] wall

    I finally got the serial threading working perfectly, so HERE is another video of the wall running at 60fps!

    WS2811 on Teensy 3.0 using FastSPI_LED library

    Hey giorgio, I ran into the same issue (check it out HERE) and I'm not even sure how I fixed it. As you know the issue could be lots of different things. So... I'm sure you've done most of this stuff, but here are a few things to check for anyway: Bad or single-TT hub (more info here) Bad...

    Still have a few issues to work out, but we got the full wall working today!! Video Here

    first small scale test of our 160x80 [Video] wall

    So.... The good news is. We got half the wall working!!!!! Check it out: http://youtu.be/oPIEFAmBrxA Now for the not so good news that you may or may not find helpful... It's taken me between 28 to 30 millis to send the data to 5 teensys. I got around that by threading the serial...

    WS2811 on Teensy 3.0 using FastSPI_LED library

    Quick note on the boards... The teensys are being powered via USB, not the 5V from the board. I did this because I needed a way to turn off the LEDs without killing power to the teensys.

    You'll find the eagle board file HERE. It works for me, but because I have no idea how you may use it... please... use it at your own risk (etc, etc...)

    WS2811 on Teensy 3.0 using FastSPI_LED library

    I'm using 10 of these power supplies. So far they seem to be working perfectly. **update I should also note that I'm powering 160 LEDs per teensy pin from both sides. And I'm the pumping 60A of DC thru a 3"x2" prototype board I had printed at OSH Park. Here is a photo of it: please note...

    WS2811 on Teensy 3.0 using FastSPI_LED library

    The white LEDs could be a voltage issue. Does your power supply have a way to adjust the voltage? Try lowering it and see if that clears up the white LED problems. I'm running about 4.75v with 220 resistors on each signal line. If I go even the smallest bit over 5v the LEDs start turning...

    Yeah I'm a bit worried about that, but I'm hoping the brightness slider will keep the power usage down.

    first small scale test of our 160x80 [Video] wall

    It is very bright Wozzy! But I just added some gamma correction which helped even things out a bit. Here is another video of 1/5th (32x80) of the wall using 2 teensys: Next step is 80X80 (or 1/2 of the wall) using 5 teensys :)

    first small scale test of our 160x80 [Video] wall

    Here is some video of our first test: Here is only 1/10 of it's total size, but by completing this step, we proved that our overall system design worked! Second test: Here is 1/5th (32x80) of the wall using 2 teensys. At this point we have two teensys working together. Thrid test: 1/2...

    WS2811 on Teensy 3.0 using FastSPI_LED library

    Everyday and then some... But it should be used as an example of threading that works (at least for what I'm doing). It's not plug-n-play or a library or anything like that.

    If you need help on the threading you can checkout my code HERE. But be warned... it's ugly and far from done :P

    WS2811 on Teensy 3.0 using FastSPI_LED library

    Some quick advice: 1. Windows likes to change serial ports around for no reason. Make sure you check for this. 2. Have you tried threading out the teensy sends in processing? This way you'll be sending all 7 serial data streams at the same time.

    Hey Guys, I too am working on a large 160x80 mobile video wall for this year's burn. It uses a kinect, reacts to music (via minim), plays video clips, etc... You'll find the code here: https://github.com/hluisi/LEDWall/tree/master/processing/LEDWall Please note that the code is far done...

    Just read the title. It says 64 w/ 64 inside. Not sure how different it is from the 60 per meter, but my guess is they are almost the same.

    I ordered 5 meters of a 64LED per meter WS2811 strip a few days ago. Can't wait to test this puppy out.

    Hmm... So around 30ms for 8000? If so that's fast enough. I'm doing a 128x64 Video wall and had written off the WS2811's thinking one could never get that kind of speed.
