    @ExplosiveGuy1 I had this clock running for hours with a minute going by every 8 frames and it didn't break once. I did the same now and left it running for a few minutes and it didn't break either, so I can't reproduce the breakage.

    Oops typo, a BRAY can carry up to 30 bits of information.

    @RaconTPT Adding two more numbers to the display for seconds is possible but the design would get more complicated and bulky because all segment on/off information is encoded on a single BRAY right now. A BRAY can carry up to 31 bits of information and it's carrying 28 bits (information for four 7-segment numbers), so I'd have to duplicate the encoding/decoding logic below the segments (like the random number generator in id:2785774).

    E should add a second "hand" so you can easily see it working.

    It's a "clock on a chip" basically.
