  • Publication number: 20110070570
    Abstract: An insulating baseboard which contains within itself a number of embedded magnets, accessible from top and bottom surface, which locate and hold in place component holders on which can be located ferromagnetic rods which when assembled combine to create electronic circuits. The component holders include eyelet cores and may include electronic components which align themselves with the magnets embedded in the baseboard and in turn hold in place ferromagnetic rods positioned on top of the eyelet cores. The ferromagnetic rods lie in a horizontal plane above and in parallel with the insulating baseboard and in-line or at 90 degrees to each other when viewed from above to produce a working circuit that replicates standard schematic circuit diagrams. Non-friction vertical connections can be made by means of connecting wires having ferromagnetic ends and which are held in place within the hollow part of the eyelet core by magnetism.
