I found a couple of these trees on sale at Lowes after Christmas.  I replaced the white LEDs in the tree with Tri-color LEDs and wired them up to one of my D-Light DC boards. Great idea at first, except it didn't work.  I could get the LEDs to change colors manually, but since the LEDS used a common cathode they wouldn't work once connected to a controller.  Fortunately I had taken my proto-type to the OKC Mini in April and met Greg who very graciously created a circuit that allowed me make the LEDs and D-Light work together.  I do apologize in advance for the less than stellar video, it's obviously time for a new camcorder as my Canon is simply unable to catch the red LEDs. 

Remember this is my site and my opinions, I'm not an expert at anything, if you have questions or constructive comments e-mail me, and finally, please don't post any of this information on the TCL site or boards.  Thanks
