Abstract

Embodiments of the present invention provide building blocks with internal electrical circuits (such as LED circuits) that can be mechanically and electrically connected to other blocks with integrated mechanical and electrical connectors. Each block in the present invention may include a plurality of mechanical and electrical connectors that can be joined with the connectors on other blocks. It is desired in these embodiments that the electrical connectors are designed such that they cannot be connected in a manner that results in a short circuit, either due to improper connection of the blocks or due to contact with an external conductor. This is achieved by using card edge type electrical connectors with complementary receptacles. Additionally, the electrical connectors have their contacts arranged such that the proper polarities are maintained regardless of the orientation of the blocks. Certain embodiments of the present invention also provide blocks that can be connected in three dimensions. To achieve this, each block has connectors on a plurality of faces and nearly any block can be coupled with any other block.
