    Hi there,

    I need a circuit that will stay off for the first 5 seconds and
    then stay on for the next 10 seconds and then must not do anything.I
    figured out that it's not that easy to do something like this and a
    simple .So I used my 8051 to implement the logic but realised that
    it's too much for a little logic and searched the net but didn't find
    any appreciable results.So I need a pulse generator circuit that will
    start with off state and goes to on state, that circuit must have a
    duty cycle of 75%.


    Thank You,
    Prizark
