An educational kit for teaching kids/beginners about designing electronic circuit is provided. The educational kit according to the current application comprises of; 1) a square hard board that is comprises of; a face board made of stiff non-conductive material, including but not limited to, plastic such as PVC (Poly vinyl chloride), wood, paper hard board, etc.; a brim made of the same material of the face board with 3 mm thickness and 2.5 cm width and a steel plate adhered to the back side of the square board with glue, 2) pluralities of various kinds of electronic components, such as resistor, capacitor, etc., which have wire type leads/terminals (5) for connection, 3) pluralities of small permanent magnets (4) of circular shape, 4) a part box (1-2) that holds the electronic components and the small permanent magnets, and 5) a separate manual (6) wherein various electronic circuits are printed. Pluralities of dents of circular shape and square shape are developed on the face board to receive magnets and electronic components, respectively. Another embodiment of the hard board is comprised of; a back board made of stiff non-conductive material of 3 mm thickness; a steel plate adhered on the back board; a paper face sheet (2′) whereon pluralities of square shape spaces (8′), which is surrounded by narrow non-conductive material, are developed throughout the paper face sheet (2′) and adhered on the steel plate; and a brim (1-3) made of plastic, such as PVC, PMMA (Poly-methyl methacrylate), and surrounding the paper face sheet (2′), with 3 mm height and 2.5 cm width. |
