    Question Some general Mega Tree advice wanted

    Hi,

    My first post for my first mega tree.

    I am Michel from the Netherlands (Europe). I am planning to build a roughly 3 meters (10 foot) mega tree.

    The materials I have already ordered:
    - Falcon F16V3
    - The ORIGINAL 12mm Pixel/RGB Mounting Strips (BLACK) (30x95,5"=72 meters)
    - 32 x MISR Clip
    - 1 x ChromaStar 15" Single Ring (40 nodes)
    - 1000 ws2811 5v pixels (20 strands of 50 pixels)
    - 2 power supplies: 220V AC to DC 5V 40A 200W
    - 100 meters of 3x1,5mm2 (3x˜15awg) wire
    - 20 pairs of waterproof 3 pin connectors
    - 5 separately ordered WS2811 5v pixel strands 50 pixels.

    I was thinking of building a 180 (half tree) with 16 strands of 50 pixels. Including the star that should get to around 3 meters height.

    What I am wondering is, given the ordered materials: Would this be your choice, or would you guys build it differently? Maybe a 360 tree, more/less strands....etc.

    What is best practice as to wiring this tree? I have been reading several topics, but was unable to find out what is best practice for such a tree.

    My questions:

    - Power requirements?
    - How many strands on one channel/data line?
    - Power injection required? How many strands of 50 pixels tied together can work on 1 power/data feed?
    - Are there some wiring drawings I could learn from?

    Thanks!

    Michel

    I've since gone to a metal base 100_2522.jpg White PVC is a cover to keep out insects and rain during storage.

    I tried reading your 37 page long topic, but is seems that's mainly about the mechanical challenges.

    I am looking for the electrical information as outlined above.

    My way, if using 5 volt pixels 1st 2 strands 50 up and 50 down (power and data in, bottom) /\ (bottom, Power injection only). Wire tops together.

    Ok, so If I understand correctly:

    1 strand up, on the bottom of the first strand only DATA-IN (no-power), then tie together at the top with the next strand, on the bottom of the second strand insert power and connect data-line to the nexxt strand.

    How many strands are data connected on 1 channel of the F16V3?

    With what you have I would use 8 ports/outputs of your F16V3 for the tree. Either turn down the brightness or power inject at the end of each string. 8 strings with 2 strands per string

    Thanks, I'll do that. I was not planning to scare the neighbours anyway ;) 30-40% will be plenty of light.

    I use one outlet on the Falcon for two strands. so NO to "connect data-line to the nexxt strand." power injection only at the end of the 2nd strand.

    Repeat for the next two strands, etc.

    You can add more pixels per outlet but I prefer to try and limit pixels on each outlet to 100

    Another option: Mine is a 24 string 50 pixels per string. Use 3 outputs, +1 output for star. Beware, the strings are not interchangeable, as some go down, some up, pwr injection. A1-A6 is pwr inject, D1-D3 is data, M=Male connector, F=Female connector. S=String #. Star not shown, but is D4.
