    I recall that the *ist D version of this software worked with other *ist
    cameras. You might try downloading this new version and see what happens
    when you run it.

    The software knows that something's connected, because it crashes when I
    trun off the K100. And the camera is obviously getting something from
    the software, because it isn't just in PC mode when the software starts
    up. But I can't get any control of the camera, and the camera does show
    up in the Remote Assistant software.

    I'm currently tinkering to make a timed remote release - I'm working on it
    being able to do both timed bulb shots, or timed multiple triggers (ie time
    lapse).

    The remote release interface is incredibly simple - just a 2.5mm stereo
    headphone socket. Short the base and ring to initiate AF, and short the base
    and tip to fire the shutter. Hold the base and tip shorted for a bulb
    exposure. So it is fairly basic electronics to make a timer to control
    these. The slightly more complicated electronics is determined by how much
    control you want to have over the timer functions.

    If I wanted to, I could control it by computer from the parallel port with
    only a handful of components, but I'm wanting to make a controller that
    operates standalone from the computer, because it is not always possible to
    use a computer to control something that goes for several hours in the
    field.

    Once I finish my design (not sure how long that's going to take, cos I don't
    get much time to tinker) I'll post here with a link to the circuit diagram.

    BTW - such a unit will also work directly with EOS350/400D's, because they
    use an identical remote interface.

    I used to have an interval timer for my super-8 movie camera, it ran off
    a battery pack with several big flashlight batteries in it that also
    powered the camera. The timer itself was just a cheap little thing the
    size of a walnut with a dial for the interval. I don't recall but it
    probably operated something similar to the stereo headphone socket.
    Maybe you could find one on ebay and use that. I used a laptop for my
    D70 & that's a hassle to set up, it'd be more convenient to have a
    simple compact interval timer.
