Design based on Matt Johnson's snowflake.

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)
36469

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.
36473

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.

Main post showed up again. I can't figure out how to delete a post.

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. :yeah:

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.

Hi Blk69,
There are 216 lights on my "paired-light" snowflake.

I'm pretty sure a single line would be plenty bright. :rolleyes:
It would be thiner of course... similar to this star (if you imagine only the outer-most row):

Nice job...wondering how long the second one will take

Came out awesome. Love some of the effects.

Super nice. Great DIY work without a welder. I hope you keep building.

Really nice job! I built some snowflakes using acrylic but I'm not sure how I'm going to hang or mount them. How are you going to display yours?

I sandwiched 2 angle brackets on the main wireframe (seen on the top of this image) with 2 screws so the angle brackets stick out in the back. I ended up drilling through the wall stucco and screwed in 2 concrete anchors (similar to this one (https://www.starhanger.com/products/copy-of-cloud-hanging-1-4-20-beam-clamp-sku-610)) I purchased from Lowes. from which I could screw in an eyehole screw in each. The eyehole screws line up with the angle brackets and I put a lock through each.

I realize I could have wired it differently, but since I added the center pixels I had to loop the pixel string around like this (from pixel 28-29) to continue adding lights. The center of my snowflake is too far a stretch from one pixel to the next to reach back up to the middle star in one go. So looping the design around solved that issue. Then I just repeated this pattern for the remaining snowflake arms.
39604
Then it's just a matter of making a bunch of submodels to match the pixel number.
For example, one of my submodels is called "Crow_1" (it reminds me of a crow foot).
Since I want it to start in the center I made the node range like this:
"27,28,1-26"

Here is my 32" Snowflake Jig:
39606
and my 24" smaller snowflake jig:
I did not use the outer circle as it was much easier to JB weld epoxy on straight wires so my snowflakes have an outer hexagonal shape. :)
39607
This is how I arranged the snowflake branches to overlap the main wires for extra JB Weld Epoxy support. All 3 snowflakes survived the 2017 season and only had 2 epoxy connections snap. This is definitely a great alternative if you don't have access to a welder:

And here are my 3 completed snowflakes waiting for next year's show!

And lastly, here is a short video clip of them in action from my 2017 show:

Those look really good. I also like the different size arches. Cool design.

Well managed to finally finished my first snowflake thanks for the instructions on the jig using matts still was genius. So just got 2 more 24" to do starting it tomorrow. Very useful for us that don't own a mig .
