Lego Logic Gates

Posted by timothy on from the three-little-words dept.

Thud457 writes "LEGO Logic Gates - It's like Babbage, but with bricks. All the gates except XOR are here, and he goes on to develop a clocked flip-flop. While practical mechanical computers may be out, even at the nanotechnological scale, nanomechanical memory may be in. "

    XOR can be constructed by combining other gates. You acctually just need NAND-gates to be able to create any other gate or larger structure.
