I did it in vixen, and shrunk the grid so I could work on chunks at a time. The video is only a 90 sec sequence, I'm sure using the other tools would help a lot. I just didn't have time or money to learn a new product when i already missed christmas this year. The hard part is remembering that nodes 41-80 on each string run backwards.
As far as a mega tree, i went with nodes to still gives it a Christmas tree look. I felt that if I went with the strips, it would look too straight. Then, I might as well go with other geometric shapes.
I zip tied each node around the body of the node to the support rope in an attempt to keep the water out of the other side. My smart strings are out of the first batch and some even had the node PCB exposed. I plastidiped ( plus thinner) them, and even added silicone to the obvious problem nodes.
So far, so good, yet it hasnt rained ( or snowed)
I'm actually trying to figure out whether I should use smart strings on other things (like mini trees) as opposed to the costs or putting on 4 strings of leds ( rgbw) plus a controller.
