    Default Startup Project - Leaping Arches

    Hello all,

    Upcoming xmas i want to have 4 leaping arches.
    2 by 2
    larger ones in the back, smaller ones in the front.
    looking to make them out of pmma tubes or hdpe.
    8ft and 6 1/2ft
    filling the tubes with adressable ledstrips from Ray Wu.

    do i need to powerinject the led strips?
    it will be 4 individual strips. on 4 channels of the sandevice e682.

    i have nothing atm.
    so i guess i need a raspberry, powersupply for the controller, and powersupply for the led strips?

    or only 1 powersupply that drives the controller, and through there the ledstrips?


    regards,

    Sammy2004

    if you are running each strip on its own channel from the board. you should be ok. are you strips 30/10 or 60/20?

    Strips are 60/20. That's why I chose for 4 channels.

    How about the amount and placement of powersupplies?
    And do I need to pull extra gnd to end of each strip?

    judging by the size of your tubes, looks as if you will be using 2 - 5meter rolls of strips. using 60/20 will yield 200 leds or 600 dmx channels. albeit larger than 1 universe, why waste 3 outputs on your board. u could run them all off 1 output. you will have to power inject, but it will still be less wires running out to your props. as far as the placement of the powersupply to many options. do you have other props that will be fed from this power supply or only the arches?

    Only the arches. (it's my first year building stuff)
    So I count the IC total to fill the channels. And not the 60leds per meter?

    And no need for powerinject when I use 4 channels?

    Was planning to have the raspberry indoors. And the controller and powersupply in a box near the arches.

    oh you still are going to have to pwr inject. just saying instead of running 1 cable per output to each arch. you could run 1 output cable to the 1st arch, then 1 pwr to 1st pwr injection site, but if you run a large enough awg for, like a 14awg you could jump a 2nd or even 3rd leg from the incoming pwr injection cable to your 2nd/3rd pwr injection sites if needed. so that would only give you 2 cables running out to your arches. 16awg might work also. but yes you are correct, if you run 4 outputs you should not need to power inject.

    as far as the light count goes

    Total LEDs per Strip: 300 of 5mm x 5mm (5050) RGB LED Lights
    Total Individually Controllable Sections per Strip: 100 Sections (20 per meter) - each 1.97" (50 mm) in length, contains 3 RGB 5050 LED lights per section
    Total DMX channels required: 300 DMX Channels (100 sections, each with three channels - Red, Green, Blue)
    Color order: BRG


    in a 60/20 you have 300 leds, but 3 leds count as 1 pixel. so you have 100 pixels per strip or 100 IC. 3 channels per pixel gives you 300 dmx channels. i ran 30/10 this year. basically 2 of my strips makes 1 of yours. i ran 1.5 12v strips in 3 arches with no power injection. only the power from the board and i was OK.

    Ok awesome.
    That's a really great reply!
    So if I understand correctly.
    I could use 4 channels. And not need to power inject.
    I can just use 1 powersupply to power the controller.
    And it will be enough to power each of the 4 channels which will each power 2.5m of ledstrip smd5050.

    Xmas 2018 I will probably make OR pixelstars hanging on a wire diagonally through garden OR pixelmatrix 8*4ft

    Good news.
    Guess my next step is to find the tubing cause nobody selling it near me.
    And shipping overseas is crazy tbh.
    Might have to try and import from China.

    And this.
    12V/350W switch mode power supply,LED power driver,AC90-260V input,DC12V/350W output(constant voltage

    5m DC12V 60leds/m 20pcs ws2811 ic/meter(20pixels) led digital strip;IP68;waterproof in silicon tube

    OP, You should just run through your math on that one before you commit.

    When you power inject like that you need a bus bar, fuse holder, fuse, connectors and T-splitter. Compared to plugging the lights directly into a E682.

    If you happen to be building E682's yourself, the cost of the E682 per port is not much higher than the cost of power injection, and you have many fewer points of failure.


    It may not work for you, but it's just something to consider.
    2016: 21500 pixels, 24 E682's. 6 A/C with 2 LOR
    2015: 7500 pixels, 11 E682's. 35 A/C with 3 LOR
    ...
    2011: 64 A/C channels with 5 LOR
