This amazing kit produces beautiful glowing color shapes that are mesmerizing and soothing. Colors are produced by ultra-bright Blue, White and Red LEDs. IC circuitry causes the patterns to appear and then fade away as the color changes. Features variable color fade rate control and comes with a 3" x 4" white opaque panel (you must provide a box or mounting arrangement for the panel as only the panel is included with the electronic kit). By experimenting with the angle and distance between the opaque panel and LEDs, you can create some stunning visual effects. Operates from one 9V battery (not included). Size of PC board: 3" x 4". Complete with all parts, PC board, Opaque Panel, and instructions. Skill Level 2.
