So I built this monstrosity of a snowman a few years a go. At 26' tall I think he earned the name. My kids could use it as a jungle gym!

A true nightmare to wire! 3 LSD48's, 2 Renard SS 24's, and 2 Meanwell 600 watt 12v power supply's.

It did have a few advantages, for example, you didn't need a flashlight at night to make repairs!

So we stripped all the led strips off. They were just cool white. Then removed the conduit inner frame to leave only the square tube outer ring. I then cut sheets of the black ABS used for the Pixabulb Strips and made inserts to fit the rings.
This is the head. It is 6' in diameter. The spokes are made of 17 spokes with 10 pixels per spoke. The ring is 100 pixels driven by e682's. The facial parts are all Dumb RGB's that will be driven by Ren24DC's from DIYLEDExpress.com.

Adding the pixel spokes

Adding the Dumb RGB's. Looks kind of like Mickey Mouse.

The front side. I still have to add the three pupils on the right and finish the wiring.

A quick video of middle ring. It is 8' in diameter, 18 spokes of 14 pixels, and the ring is 120 pixels. This was also mocked up to see how power is needed in the arrangement. If you notice the color wave when it goes to white, the lower left side of the spoke flicker. I wired these with 16' of of 18ga wire from the e682 to the first pixel and that is it. Whereas the top right is wired the same way and then an 18ga wire jumps from pixel one to pixel 126 making a power loop and no flicker at solid white. I also did this for the outer ring.

A lot less than he did! The spokes were made of 1/2" conduit. Now the ABS is strong enough to span the entire thing. The original wiring used up 4000+ feet of wire. Now I have a lot of 2 and 4 conductor to re use! Before, the middle ring was 44 channels. Now it has just 3 pixel outputs.

Mind=blown James!. Amazing and inspiring!. The first iteration was amazing and this is even more impressive!. I never got a chance to see finished pics of the controller boxes before so thanks for posting

In the words of Mick Dundee, That's not a hat, This is a hat!
The hat is out lined by dumb RGB's with a 30x14 pixel matrix.

Since I have heard it all day from my 5 year old, Do you want to build a snowman?

Getting there! He is all put together now. I still have to upgrade the control boxes but so close!

Well, the snowman is up and who says he has to always be a snowman! The pixel upgrade was well worth the effort!

What is that black material your using for the hat? Looks like you used it for the face as well. -=Steve

Nice, a couple nema 3r hoffman cans with the back planes, those set you back a couple bucks not counting the hardware, unless you can go down to platt or graybar.......

Originally it had a 1/2" conduit frame that held LED strips. I removed all of that and made Black ABS inserts that are ziptied to the outline. It is the same material that we make the pixabulb strips out of.

Those are actually recycled cans bought from a local surplus guy here in town.

Then your lucky because if their Hoffman, they are about $66 each new, I also like to poke around second hand stores myself. I'm cheep. By the way my Grand Father was Jimbo, he was born and raised in NC and passed back in the 80's, I still miss him.........
