Lego Logic Gates

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. "

  1. No need for XOR by Anonymous Coward · · Score: 5, Informative

    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.

    There may be no obvious immediate use for mechanical analogs of digital circuits, when digital circuits are orders of maginitude faster than mechanical circuits

    If you scale things down a bit, mechanical 'circuits' can become a lot faster - and combined with the electrical properties of the components there might be an interesting hybrid some point in the future.

    Still, using Lego is just a little insane, and there is the minor problem of a '1' or a '0' slowly degrading into '0.5's further along the Lego logic chain... :-)

    MirrorDot appears to be down at the moment. In the meantime I mirrored it here. Unfortunately my web host isn't that generous so I'll probably take it down very shortly. Those that want to mirror the mirror can grab a zip file copy here

    If you mean software to simulate building digital circuits out of gates, look at TKGate.
