    Hi all,
    Here is how I am looking to build my MegaTree

    Pixel Specs: WS2811 12V Square Pixel Nodes fitted to strip
    12 Strings of 170 Pixels connected to 12 Outputs of Pixel Controller (Falcon F16 V3).
    24 Stands of 85 Nodes per Strand

    Tree Height approx. 4 metres
    Base Diameter 1800 mm
    Head Diameter approx. 300mm
    Viewing Angle: 180 degrees

    Mega Tree Pole
    5.5 metre 40NB galvanised pipe (outside diameter 48.3mm with 4mm wall thickness)
    Pole inserted 1 metre into ground via sleeve in ground and will be tethered at top via 3mm stainless cable
    Next step was to figure out how to install Mega Tree in front yard.
    Location selected is near side of house to try and get maximum viewing distance from the street in front of a small garden bed.

    I needed a way of securing the Mega Tree pole in the ground

    Decided to core a pvc pipe into the ground that is a snug fit to the 40 NB pipe (didn’t want to concrete sleeve in as yet as not 100% sure of location).

    About ½ way into the ground with pole sleeve

    Sleeve 1 metre into ground (since fitted a cap to top of sleeve to stop it filling up)

    Also fitted a base in the bottom of pole sleeve to stop the pole forcing its way further into ground and making removal of pole difficult.

    Pic showing pole (sorry a bad photo with sun in background) but you get the idea.

    Base Ring for Mega Tree
    1 inch galv water pipe (old scrap piece I had lying around) bent into semi circle with basic pipe bender

    Bending pipe

    1800 mm Diameter base ring with
    Strand spacing 125 mm
    Drilled holes for ¼” “J Bolts” to attach strands (Yet to make up or purchase)

    https://www.dropbox.com/s/8kiupjdvo8mykt1/Photo 6-7-18, 1 25 00 pm.jpg?dl=0

    Base ring will be approx. 500mm of ground and secured with steel droppers into ground.

    Mega Tree Header (top piece which strips are attached to).
    https://www.dropbox.com/s/m3nir8mizcl7f5u/Photo 7-5-18, 10 21 20 am.jpg?dl=0


    Wanting a way to raise and lower Mega Tree header with strips attached.
    Decided on using a cable winch (a cheap Ebay boat winch) and a cable pulley near top of pole.
    Needed a way of mounting winch to pole so made up a winch plate adopter from some scrap 5mm x 100mm aluminum plate.

    Winch plate secured to pole with round pipe clamps (allows winch and plate to be fitted when pole is upright.

    https://www.dropbox.com/s/7gwvuciprgrl4vy/Photo 6-7-18, 9 56 56 am.jpg?dl=0


    Using a basic Bunnings cable pulley
    https://www.bunnings.com.au/zenith-50mm-zinc-plated-wall-ceiling-single-pulley_p3950321

    With winch plate sorted used similar method to for securing pulley for winch cable for top of pole.

    https://www.dropbox.com/s/12s3w2v9l9r4fs5/Photo 6-7-18, 11 41 07 am.jpg?dl=0

    Just will have to remember to feed cable from winch up through cable pulley before inserting pole into ground sleeve.


    Here is what it will look like (mocked up on a short section of pipe)

    https://www.dropbox.com/s/muzskw0cxo7w96j/Photo 6-7-18, 11 51 50 am.jpg?dl=0


    Still got to sort out how header will slide up pole (need to hole saw centre of header and probably fit some type of guide rollers to help it slide up and down pole).


    Also need to fit guide wire mounts for top of pole, probably use more pipe clamps etc.


    Updates to come

    MegaTree Star

    Double row 5 pointed star made with 5mm flat aluminum with square pixel nodes secured in strip and cable ties to aluminium.

    https://www.dropbox.com/s/0zkjfp8w11k45cq/Photo 25-4-18, 1 59 18 pm.jpg?dl=0

    Need to make adapter for star to pole etc, Updates to come

    Not sure yet if star will be attached to header of simply attach to top of pole

    Updates to come.

    Just to let y
    Just to let you know - Depending on your soil type, they can start filling up from the bottom too. But not as quickly from the top.
    If it fills up too much, you can jet water down the pipe to flush it out.

    Ok a quick update

    Firstly I have decided to increase the density of my Megatree
    So going from 24 strands of 85 pixel nodes per strand @ 180 degree viewing angle to

    32 strands of 85 pixel nodes per strand @ 180 degree viewing angle. I wasn't going to do this until next year but decided to go ahead with it.

    One of the design aspects I wanted to have was the topper being able to be fitted when the MegaTree pole was in-situ.

    ie Fit pole into ground sleeve with top pulley plate attached and guy wires attached.

    Then bolt on winch with winch plate and bolt on sliding tree header (topper)

    So come up with this somewhat crazy design for the tree header


    View: https://www.dropbox.com/s/dafalupg4a0qy8a/Photo%2015-7-18%2C%201%2054%2000%20pm.jpg?dl=0


    its just a "mock up / prototype so to speak" and will add some more bracing if needed, clean up and paint etc

    So bolt the topper together around pole, and using pvc pipe as a bush to allow the header to "slide" up and down the pole easier.

    Header to be winched up with boat winch and secured in place with the ratchet on the winch.

    Need to also add something to header to attach winch cable to.

    Not to sure yet as how going to secure strips to topper yet, was looking at small carabiner things but may just use hook bolts.

    Make sure you you have somewhere to anchor/hold the cable down low - or perhaps on the winch. It's amazing how it pulls itself back out of the pulley and down to the ground when you're wrestling with the tree trunk.

    Ok another quick update on the tree header
    Here it is, yes it is looking a bit messy and a weird contraption, but hopefully it should work ok

    I have added some bracing to the top which will also be the lifting point

    View: https://www.dropbox.com/s/qvtegxg3dgyf92v/Photo%2018-7-18%2C%201%2050%2054%20pm.jpg?dl=0



    Here it is "mocked up" on a small section of pipe to give you a idea of how it will work (well hopefully work).

    Note; Piece of steel plate attached to end of small lengths of strip just to see how the strips would hang down.

    Next thing to do is come up with somehow to mount the MegaTree Star topper I made up.
    Star approx. 1300mm from top to bottom.
    Going to need to add some bracing etc and mount to tree header?
    Or may just attach to top of megatree pole via clamps yet, if I go down this path I think I will need to come up with a idea of being able to tilt up the megatree pole.

    Not sure yet, any ideas??
