Paper Circuits
Materials: Copper tape Surface-board LEDs(you can use normal ones,but surface-board is flat against the paper) Soldering Iron(or tape) Paper Code bug with the code at right Directions: Lay out tape on the paper in a straight-line star,making sure that the lines all come to meet in one point.Cut a small sliver away in the center of the lines, so that they look like railroad tracks.Cut one side of the railroad from the center,so that its isolated.Lay the LEDs across the tracks,the negative side on the side thats cut away from the center. Attach the LEDs to the tape,and tape leg 0 of code bug to the isolated side of each LED.Then,tape the power leg to the center of the star.Hook Codebug up,and watch the LEDs flash!
