Snap Circuits uses building pieces with snaps to assemble different electronic circuits on a simple "rows-and-columns" base grid that functions like the printed circuit board found in most electronic products. Each component is easily identifiable by a different colour and functional purpose. Snap Circuits 3D-M.E.G. focuses on fun with "Magnetics", "Electronics", and "Gears". Includes over 160 projects, utilizing 60 parts and unique "stabilizers" for building amazing "3D" Snap Circuits structures. New component parts include 3D Rotating Snaps, unique 2-Sided Base Grid, Rotating LED Lights, Fiber Optic Tree, Rotating Mirror Ball, multiple-sized Gears, melody IC , Magnetic Switch and more. Bonus circuit projects for users and owners of other Snap Circuits kits to build bigger and better projects. Learn the basics of electricity, engineering and circuitry with full colour, curriculum-rich, easy-to-follow instructions.
