Christmas Tree Projector
Here’s the ultimate solution if you’re still having trouble getting the tree up in time after having tried the Last Minute Christmas Tree.
This DIY device projects an image of a Christmas tree, up to five feet tall depending on how far away you place the unit, onto your wall.
It uses three LED’s, the green light stays on and forms the image of the tree. The Red and White LED’s flash on and off randomly like lights on a real tree would. The flashing is controlled my a Picaxe 08M micro. The unit is powered by a 9v battery regulated with a 78L05. The body of the unit is made from a plastic pipe the ends are cut out of thin plywood.
