Imagine how much easier the holidays would be if setting up and decorating a Christmas tree was as easy as pushing a button. No tinsel all over the place, no lights to hang, no ornaments to break, none of that hassle. Well unfortunately this DIY Christmas tree projector is about as close as you can get to that dream at the moment.
The projected tree includes red and white flashing lights and can be resized on the fly to fit any room by just moving the projector closer or farther from the wall. Construction seems pretty easy too, if you have a basic grasp of electronics and soldering:
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.
I’d actually like to see something like this taken to the extreme where instead of a bat-symbol being blasted into the night sky, you’d see a giant blinking Christmas tree. And instead of delivering presents, Santa was some kind of awesome vigilante crime-fighter. I hope Alan Moore is reading this.
