This project was to make an interesting geometric design with LED lights that show 3 patterns. The protype that I made out of cardboard is supposed to be freestanding, have an interesting geometric design, have 8-16 LEDs, shows motion have 3 LED patterns, fit on a 12x12 piece of plywood and have easily accessible electronics
The Octagonal prism is an interesting shape and it is freestanding because it will not fall over if you put it down on its own. It has a total of 8 LEDs with 3 pattern, and the changing lights show motion. The electronics are on the inside, and the top comes off to make them accessible. A 12 by 12 piece of plywood has 144 square inches. The eight 2x4 sides take up 64 square inches, and the octagons take up about 35 square inches, making a total of 99 square inches, well under the limit, And the electronics are in the inside, attached to the top, which can be removed to access the lights.
The lamp has been glued together and meets all constraints. It has 8 functioning LED lights (see pictures 5 and 6) and is the same as the cardboard version, except is is made of wood and the angles were sanded to fit together (see picture 7)
The pictures here show that the LED have all been installed, and there is a space for the cord to leave the shape. The last picture shows that the sides have been sanded to have them be at the correct angles, the second to last picture shows the angles of an octagon. One side was sanded at a 45 angle, and the other was left at 90, making 135.
