    see previous posts... It's not really a question - of course it's easier and faster - but still want to look at it...

    I'm doing a 16 x 85 colour 'trix' but its with string based pixels. Hopefully will have it finished in the next few days.. Pictures and stuff at

    Making a matrix of single RGB LEDs are fairly easy.
    DMX Pixels may be one way to go.
    Either way, we need a technique to convert video frames to a matrix of LEDs.
    DMX is not really suitable. 512 ch /3 = 170 LEDs or 17 x 10 LEDs

    Wouldn't it be better use stand alone unit that has various videos stored on a SD card. you could then use a couple of DMX channels to chose the Video from the SD card. Another channel could be used to select the speed.

    If people want to run this standalone, it would be a good idea to add an RTC of some sort.

    The only additional thing I would like to suggest is the ability to use commercial 8x8 led matrix packs. It would be a great way to add the option for some added simplicity, and are similar in cost to the $0.15 discrete RGB LEDs spec'd. They keep with the 8x8 matrix building blocks already established, are available with 3mm and 5mm lenses, and come in single color, bi/tri color (RGY), and RGB modules. The 60mm RGB matrices can be found for $11, which would be $132 for a 16x48 matrix. A bi-color matrix can be found for < $2 per module. The cost of PCBs could also likely be reduced with these. They lend themselves to mounting on protoboard quite nicely, though there is the MCU circuitry to consider as well. Depending on desired use, there is a potential limitation in regards to pixel spacing, though support for modules like this would certainly not preclude the use of a hand assembled matrix.

    I would also second Matt's and Phil's thoughts, though these things may be beyond the scope of LEDTriks. Adding DMX support, and Renard for that matter, would greatly expand the utility of this. I definitely like the idea of being able to run totally standalone or semi-autonomously. That said, It's entirely possible to get these features by implementing the Triks-C protocol via another MCU and interfacing with that controller instead of the LEDTriks controller directly. I almost like that better, provides a nice abstraction layer boundary. Is a protocol spec and/or the code for either the PIC or client software available?

    Not sure that this has a direct impact on this discussion, but I do think that the availability of inexpensive commercial matrix packages should at least be brought up. A single color 8x32 matrix using 5mm LEDs can be found at Sure Electronics for just over $20 shipped, and a 16x32 bi-color matrix ships for just over $40. You're just not going to do something like that less expensively with discrete components. A 32x64 bi-color matrix is available on AliExpress for < $100 shipped, though I haven't been able to find docs on what control chips those use, let alone how to interface with them.

    The support for using commercial matrix displays would pretty much require abstracting the signaling from the protocol. It would be nice to see a PCB and software that's really just the base LEDTriks controller, only without the parts directly concerned with LED control. The additional code and wiring would of course be up to the user.

    EDIT: I realized that an LEDTriks object is a feature request for Ben's PropController. Other than using commercial LED matrices, all of what I'm thinking could be implemented there. Ideally, the software would support both receiving and sending the LEDTriks protocol. There is already Prop code available for the Sure Elec. matrix displays. So, pre-assmbled matrix support and implementing the LEDTriks protocol on the PropController would be my requests.

    So, budude, are you getting all this down? I only have ohhh.... maybe ten or fifteen additional modifications I'd like to add, but you're a wizard and won't have any problem with them... but chief among them is the ability to interface to my refrigerator and microwave, as well as be completely portable and run off of a single AAA battery for days at a time. It should be configurable for multiple languages (maybe use different flash memory sticks for different dictionaries), and of course, be totally compatible with every controller known to humankind as well as every operating system on the planet. Oh, and it should be easy to use and build, and have an interactive, built-in help system in the individual's native language. And the system boards should be red.

    Am I piling on yet with featurecreep??? :mrgreen:

    dirknerkle,
    You forgot the
    chrome plated grease nipples,
    twin overhead foxtails,
    and double reverse overhead twin cam door handles,
    And if this new triks board should save the world, then an ability to "support Land Rights for Gay Whales" would also be an excellent addition.

    Now can we return to regular programming.

    dirk I think you missed the most important one. It should build itself.

    I'm worried that this project might turn out like this....

    I can see what you mean, the green nail polish is just wrong.
