    Hi all, new to RGB but have done a couple of years now with dumb leds, DC48 controller and Vixen so not scared off by the software or wiring aspects. For this year I am hoping to replace my old icicles with some intelligent RGB icicles and then, if time permits add a couple of strips outlining my garage door. The longest run from the controller to the start of a strip should be 4 metres (icicles on eaves, controller in garage). Here is my current thinking:


    Falcon F16v2 as a controller (as I can use it E1.31 or with my Raspberry Pi) if I have made it in time for bulk buy #2. My garage is already wired into my network as I was going to run the DMX last year from my main PC rather than my Acer One.

    http://www.aliexpress.com/item/12V-350W-switch-mode-power-supply-LED-power-driver-AC90-260V-input-DC12V-350W-output-constant/1948832565.html x 2 for the power. running the icicles, power off the F16 either two or four universes. Or would I be better powering separately with injection, and if so how do I fuse the power?


    http://www.aliexpress.com/item/5m-DC12V-WS2812B-addressable-pixel-strip-waterproof-in-silicon-tube-30pcs-WS2812B-M-with-30pixels-36W/32348237310.html x 2 for the outlines and to play with. May end up cutting into multiple strips. Will be setup after the icicles.


    http://www.aliexpress.com/item/100-pairs-3-Core-White-Waterproof-Line-15cm-long-each-male-and-female-3core/331631241.html to clean up the connections on this and my existing lighting.


    And then, if I need to inject, some t-pieces to do this for the second icicle string in each run.


    Does this make sense? Is there anything obvious I have missed.

    Looks pretty good to me (but I still consider myself very much a noob and bow to the more knowledgeable members). They will weigh in with the power injection query I'm sure as to me, you only require 1 power supply for the icicles (5 sets pixicles @ 25W = 125W and power supplies are 350W x .85% = 297.5W) More than enough for the pixicles. Unless the 2nd power supply is going to cater for the outline.

    For the outline, you may want to consider http://www.aliexpress.com/store/product/5m-led-digital-strip-DC12V-input-WS2811IC-256-scale-10pcs-IC-and-30pcs-5050-SMD-RGB/701799_568458133.html

    By the way, the doctor tripled my dose of Prednisone yesterday, so if none of this makes sense, I'm blaming the medication, lol.

    Thanks for the comments

    Second power supply is more as a spare and if needed. I did look at the other strip but I am playing with the idea of doing a small matrix, 30 x 10 on the side of my garage.

    If you can afford it, a second power supply is always a good idea. As is a second anything! backups are great when you are at the beginning of December and you have a failure, no matter what it is, at least if you have a backup, you can swap it out and eliminate it as a problem.
    And then god forbid a failure mid season, you have it covered.

    Pixel testers are a good fault finding tool

    End caps for sealing the strips if you cut them

    You may be able to ask Ray to customise the spacing and number of pixels on each icicle drop but make it VERY clear with a diagram if you want to do this.

    Power injection may be required even if your supply can handle the wattage. This is because of voltage drop along the icicle wires and between the supply and lights. This thread has a little bit more info http://auschristmaslighting.com/forums/index.php?topic=7578.msg69740#msg69740

    When injecting power, you leave the negative line connected along the pixels between multiple supplies but always cut the positive half way between. The fuse can be put on the positive connection between the supply and injection point.

    It is recommended that you run a separate network for your display.

    You can directly ask Ray for a quote; the general opinion here is that AliExpress overestimates and overcharges for shipping when you order a variety of items.

    The group buy for the F16v2 is open until August 30th; you haven't missed it.

    I presume you understand the advantages and disadvantages of 5V, 12V strings as well as that particular strip?
