Abstract
Abstract A modular building block for electronic circuitry is provided with areas for mounting circuitry thereon. Posts of a particular geometric shape and receptacles of a complementary geometric shape are provided on the substrate. The posts and receptacles are coated with an electrically conductive material and connected to nodes within the circuit such that when blocks are interconnected, post within receptacle, the interconnection provides both physical and electrical connection. An alternate embodiment is disclosed having fingers and edge cards, configured such that the fingers of one block grasp the edge cards of another block, providing physical and electrical connection between the blocks.

Dependent Claim
48 words
The substrate of claim 1, having formed thereon at least a first edge and a second edge wherein said at least one geometrically shaped receptacle and said at least one geometrically shaped portion are proximally located at said first and said second edge, respectively, of said first substrate.
Claim 5
Dependent Claim
16 words
The substrate of claim 3, wherein said first edge is located opposite to said second edge.
Claim 6
Dependent Claim
