Arduino-Powered Wall Christmas Tree w/ Star Wars Theme LED Lights
Check out this awesome Star Wars themed build from darbinorvar on instructables!
On a 2 x 3 foot plywood board layout your branches or cut wood and either glue, screw or nail the wood to the board in a pattern mimicking a Christmas tree structure. I painted the board but you could leave it natural. Once the boards are attached you can use your scissors to cut the LED lights into a star pattern and solder them together, making sure red goes to red and black to black. Peel the tape off and stick them to the board.
Cut strips of lights to fit the wood for each branch and wire them to a lead, drilling a hole near the branch to run the line out the back of the board.
