    I was wondering if anyone could help me with a project I'm trying to put
    together.

    I'm sure by now, that everyone has seen the christmas lights that CHASE
    (this I belive is the theatrical term for it)...The kind of lights that
    have the following sequence..

        1000
        0100
        0010
        0001

        and repeats continiously, at a set rate.

        I know this can be done with TTL, driven with something like a 555.
        but have been unable to make it work. I have one of those "light in
    motion" strings at home, and have tried to reverse engineer it with no
    luck.

    I have the solid state relays that I plan on using, that are driven
        by 3-32 VDC and will handle 240VAC @ 10A.


        Anyone want to help in this venture?
