RGB Pixel Tree

We got our Christmas project done a bit later than usual this year, but here it is. An eight-foot wooden triangle filled with 51 MegaBrite RGB LED modules, controlled by an Arduino. As our projects always do...this also lights the houses across the street pretty well, running about 75 watts of LEDs maximum.

Unfortunately didn't take photos during construction, but it's nothing too difficult. Three 1x4 planks fastened at the corners with metal brackets, 3/4 square dowel cross beams, and lots of zip ties. The MegaBrites are daisy chained from a bottom corner up to the top in a zig-zag pattern. Power is connected every 7 or 8 modules, to a 7.5V 20A Meanwell supply from Jameco. For rain protection and a little diffusion, the whole thing is wrapped in a 2mil plastic drop cloth.

My thoughts: --should be

My thoughts:
--should be good for at least a year's worth of barking dog at 2 am
--at least it's pointing the right direction
--don't be surprised if someone sets up a sunglasses booth in your front yard
--only in Silicon Valley... (whew)
--I still think my vintage plastic snowman rocks and it too takes only 75 watts! also diffused

P.S. --merry Christmas!
