Abstract:
1. An interconnection board for connecting electrically-unique points on a breadboard, comprising: a conductor layer having a plurality of cells arranged in a grid of rows and columns, each cell including a confined space in which an electrical slidable conductor may slide between an on and an off position, each conductor having a conductive lower layer with a bottom side, an electrically-insulated middle layer, and a conductive upper layer with a top side and electrically isolated from the lower layer, the conductor layer further including a plurality of row conductors each adapted to contact the bottom side of each slidable conductor in one row proximate one edge of each conductor, and a plurality of column conductors each adapted to contact the bottom side of each slidable conductor in one column proximate an opposing edge of each conductor, such that a current may flow between each row conductor and each column conductor through only one of the slidable conductor in the grid regardless of the position of each slidable conductor; a magnetic layer situated below the conductor layer and having a plurality of magnets vertically aligned with each cell of the conductor layer; a contact layer situated above the conductor layer and having a pair of contacts aligned with each on position of each cell of the conductor layer, such that the contacts of each cell are electrically connected through the top layer of the slidable conductor only if the slidable conductor is in its on position, each contact electrically connected with one of the electrically-unique points of the breadboard; whereby any two points on the breadboard may be electrically connected by connecting each point to opposing contacts of one cell, applying a current to the row conductor and column conductor associated with the cell to move the slidable conductor to its on position by Laplace force in accordance with the magnetic field of the plurality of magnets and the polarity of the current, the current sufficient to produce a Laplace force able to overcome the friction of the contacts contacting the conductor, such that the contacts of the one cell are electrically connected via the conductor.
