    I have been able source RGB pixel strings (similar to MPH pixel strings) from Ray Wu. He had been kind enough to now post these new product on his web store. The price of these is nearly 1/4 the price of the MPH pixels so makes it very affordable to a lot more enthusiasts

    RGB Pixel strings using the 6083 chip is a 4 wire 5vdc RGB string that can have each light individually controlled through DMX to give some awesome effects.

    These can be found at Ray Wu's On-line store at http://www.aliexpress.com/fm-store/701799/209889132-314086573/3-chip-RGB-full-color-through-hole-led-channel-letter-6803IC-pixed-controlled-DC5V-input-waterproof.html

    Now to run these lights you will need a 6803 DMX decoder which can also now be obtained from Rays store at http://www.aliexpress.com/fm-store/701799/209915969-314083682/LT-6803-DMX-Decoder-DC5-24V-input-LPD6803-specific-protocol-output-signal-Max256-steps-.html

    You will also need a 5VDC power supply to run the lights, you could use an old computer power supply or you can get these from Rays store at a very good price at this link http://www.aliexpress.com/fm-store/701799/209855560-289599937/350W-Dual-Output-Switching-Power-Supply-88-264VAC-input-5V-350W-output-CE-and-ROHS-approved.html

    You will also need a dmx dongle to connect the controllers to the computer, these can be obtained for approx US$60 from different places in the DIY community. try looking at these places
    http://diylightanimation.com
    http://www.doityourselfchristmas.com/
    If your unsure just ask and we should be able to help

    And finally you will need good RGB sequencing software and that is Lightshow Pro 1.7 which you can download a 30 day demo before deciding to purchase (demo is limited to 16 output channels only)
    http://www.lightshowpro.com/content.php


    Now if you want to have some RGB 6083 pixel strips as well you can also use this with the DMX controller, the strip can also be obtained from Rays on-line store here http://www.aliexpress.com/fm-store/701799/209843764-306378431/LED-Digital-strip-with-6803-IC-30pcs-5050-SMD-per-meter-DC12V-input-with-silicon-tubing.html

    the strip runs on 12VDC but uses the same controller as the strings to communicate and can be bought through Rays store as well http://www.aliexpress.com/fm-store/701799/209855560-289599951/350W-Dual-Output-Switching-Power-Supply-88-264VAC-input-12V-350W-output-CE-and-ROHS-approved.html


    There are also standard RGB string lights that can be bought through Ray as well, these run on 5VDC and support for these being used through the Tiger controller range is being investigated and appears that this will work, further info on that to come. but you can take a look at the RGB light strings here http://www.aliexpress.com/fm-store/701799/209889132-314089657/Through-hole-LED-channel-letter-DC5V-input-RGB-waterproof-0-3W-120degree-beam-angle-P-N.html

    So it looks like exciting times for RGB lighting and the prices that Ray has on these products will definitely now makes RGB a serious contender


    Expect to see some reviews in the near future regarding these exciting products

    Excellent search....
    This is really great.
    I think, i will try....

    One question for my knowledge:
    How each pixel address was managed to be sure to send the right order to right pixel?
    Does the controller effects individual address regarding the order he find each pixel IC on the line?

    Means, for example i we have 3 RGB pixel Led : 1st one will have channel 1/2/3, second one 4/5/6 etc...?

    Thanks for your feedback

    Cheers, Henri

    You set the controller DMX starting address, so for example we set the controller to DMX channel 1, the first pixel in the string will be RGB channel 1 (1,2,3) and then each other pixel behind that will just cascade up until there are either no pixels left in the string or you have used up all the channels. If one pixel fails you can just cut it out a put another pixel in its place and it will still work, this is the same chip that appears to be used in the CCR and that doesn't matter which order the pixels go in as they just use a cascading addressing protocol.

    For those looking for additional information - detailed photos and datasheets, they can be found in this thread:

    I've played with these pixels and they do appear to be pretty much close to the ones MPH has sourced from ledwalker. I'd really like to see someone purchase the controller and prove that this all works as expected.

    I have an LT6803 decoder and a few sample Pixels on their way to me for testing purposes.

    Will report if and when.

    I see that the DMX Controller has a single output supporting 360 DMX channels which would mean a total string length of RGB 120 nodes, is this a supported configuration when connecting the pixels into a string. I think this will require at least 7.2 Amps to drive it, so a 10 amp psu is going to be required.

    I am also going to look at getting artnet/dmx converters as I will want to be creating larger displays and that will require more dmx controllers and USB ports. I understand that LSP will be supporting ARTNET in the future.

    This new project is getting exciting and is certaintly pushing the envelope.

    Neil,

    The intention is not to run the strings power supply through the controller power supply, but instead use an external power supply for the string or strip supply power and only use the two communication wires from the controller, this way you should be able to use the one controller to be able to control both the 5VDC strings and the 12VDC strips so allowing you to maximise your channel use to the fullest. As long as the data comms with the strips/strings are all connected in series then i believe this should work. It will be nice to actually prove it.

    Ok, ordered 100 rgb pixel nodes and controller to play with.

    things I have been thinking about (and may be answered when I receive them)

    the last node of the string, will it have a connector or pigtails to extend the string out past the 50/100 nodes on the string.

    The controller is supporting 360 DMX channels that gives capacity of 120 RGB pixel or other types of RGB strips and all nodes need to cascade from the previous node, so if you want to link strips, pixel strings to the full capacity of the controller then they have to be extended from the last node.

    Hummm...
    Not sure that the only possibility is to cascade each string...

    We need to have feedback from the first ones who will made tests...

    I take for example the other strings based on HL1606, you can cascade them (up to 3 strings 150 RGB LED), then you can have the rainbow effect from LED1 to LED 450.
    But if you cut the strings and connect them in parallel, trough a distributor (5 outputs) or directly on the controller (2 outputs), then the effects start in parallel on all strings, and all led 1 will be light at same time and so on..

    I don't know if it will be the same with these ones...

    Another remark, it's more cheap to buy 5x1 meter strings, than directly one unit 5 meters. This is what i saw
    on the site.

    Cheers, Henri

    Henri,

    Make sure you don't confuse the names, you are referring to the 8606 pixel strips and not the 8606 pixel strings.
    I deliberately put the link to the pixel strip being sold by the metre instead of the 5 metre roll as I also saw that it was cheaper.
