For my 12 strip tree i have used 2811 strip for $36, just cant go past that cheap price. The quality seems good as well. My mega tree is not a 3 dimensional tree, My tree design is simlar to this threadcwbotner said:Hi All
I am new to animation, and RGB.. and a mega tree is my priority this year.
Fast Eddy;
What kind of strip did you deside on for your Mega tree?
With the star on top the tree will be nearly 6 metres tall, which is more than tall enough to make an impact. Plus its easy to build this way as it is using complete strips.cwbotner said:All;
alot of people are talking about 50 pixels up, then 50 down for their trees, but that is only 5 meters in lenght.
1) Doesn't that limit the height of your mega tree?
cwbotner said:2) Is there a reason why you couldn't cut 1 string in half, and do 1.5 strings up, and 1.5 strings down? that will be 150 pixels per controller port.
cwbotner said:3) If I inject power per string, then how many 75 pixel strings can I go off 1 Pwr suppy.. ( What would be a recomendation for Power supplies?)
cwbotner said:4) is the 2811 chip supported yet?
cwbotner said:5) I am looking at 32 strings for a 1/2 tree. (180-200 degree view.) total of 48 strings if I do the 75 pixel.
That would mean 2 ECG PR12 correct?
cwbotner said:Will that make a respectable mega tree? It will be my 1st, and want to do it right.
Please add any other advise I may need.
Thank you.

I used Item1 customised with plastic leaves for 2010 and 2011.
2012 will see one of my megatrees converted to Item2 will be 32 strands of 50 count, they will be data wired as 100 count string but powered from the base as 50 count strings.
So I have everything ready now, have one more question. (sorry if it has been answered on another post)
I know that there is a in and out for the strings (Item-1) does the voltage follow the same in or out. If not I understand how to power both strings at the base, if not how do power them from the base?
My thinking is I connect the data and clock at the top then feed the power to both strings from the bottom
