The circuit is comparatively easy to assemble RAINBOW CLOCK CIRCUIT however construction of the cabinet needs accuracy and patience. As shown within the diagram, use a 4-6mm HD plastic sheet or laminate. Get the broad rings cut at a neighbourhood sawmill. The diameter of the inner hole of every ring is that the same and matches the diameter of the clock face. The outer diameter of every sequent ring will increase by 1.5 cm, thus LEDs remains invisible. Stand-offs are cut from wooden battens utilized in electrical wiring and glued with Fevibond.
