    Lightbulb 32" pixel snowflake wireframe EPOXY build (no welding)_COMPLETED

    Design based on Matt Johnson's snowflake.
    https://www.youtube.com/watch?v=nUQ-WkglyE0

    I am currently building the 1st of 3 snowflakes for my display, and thought I'd share the process I'm going through.
    In Matt's video, he doesn't explicitly show his dimensions on the MDF board, so I figured it out based on his ruler during the speed up scene. (32" end to end)

    Drilled out the main sections with a doorknob hole saw drill attachment and routed out the lines.

    ...and since I don't own a welder, I went with JB Weld epoxy.
    On Amazon it's $12.13 for 10z total.

    Works like a charm!

    Lastly, I ended up changing the outer circle design for straight hexagon-shaped outer support. (It's easier to glue)
    I pinched the main joints with some scrap wood and screws to glue them with pressure.

    Next step is to spray paint it all matte black before attaching the pixels. (photos to come, this is still a work in progress!)
    And I'm keeping the middle wires for support (Matt cut them out in his design) and I'm attaching 2 pairs of pixel lights on each center 'arm' to go all the way to the middle.

    My snowflake is based on Matt Johnson's How to build a Pixel Snowflake video on Youtube.

    I don't have a welder, so I'm using JB Weld epoxy. Works like a champ! Then sandwich-pinching the main joints with some screws and wood.
    This is a work in progress, so next step is to spray paint it all black and zip tie the lights on! More photos to come!

    Finished spraying and final step is add the lights and test it out!

    ^You can see the smaller snowflake under this one ready to be glued.
    My design calls for 1 large and 2 small snowflakes.

    i would be curious as to how the epoxy holds up over time.

    I spread the epoxy completely around each joint to help form a kind of epoxy x-shaped "tube". so far seems to be working great.
    Here are the latest images. Working on zip-tying the lights:
    It's taking longer than I thought, and only got around 70 lights attached. It was 1am, so I wen't to bed. Hopefully I'll finish tonight.

    FINISHED!!!

    216 lights
    Took me about 30 hours to complete
    12 gauge hanger wire
    JB Weld epoxy

    Plugged it in and tested it out. The final 24 lights aren't lighting up...
    *edit: turns out I had the incorrect number on the e682 webpage. Fixed!
    Until then, here are some pics of it lit up.

    I was thinking of doing something similar but with only one pixel where you show two. Only concern is it might not be bright enough.

    How many pixels did you end up with on your 36" snowflake. Thinking my design was a 30" diameter with around 120 pixels.

    Have used JB weld in the past. Don't use anymore, don't know why. You should be good for your application.
