Anyone used the ISD4000 series Chipcorder?

    I am looking to utilize one on a project. SPI driven interface. just curious
    if anyone has any experience with it, good or bad. (I am using the ISD1110
    on a current project...looking to use SPI to lower the pin count in the
    future)

    I guess not! Anyone interested in the ISD4000, or shall I keep my
    notes/experience to myself? ;-)

    justi did some stuff with the isd range a long time ago i still being used to
    play animal noises. but the chips i used made clicks at the begining or end
    of sound track I cant remember which. I turned then on and off with a pic.

    I'm sure a lot of us would be interested in how things go for you.
    I have, for one reason or another, always stayed away from the ISD sound
    goodies. I would be interested in what your selection criteria was/is
    and any issues you may have (or not have) making a system using the
    ISD4000. A little background on what the end product is might be useful
    too.

    I have several projects for this, but the one I am experimenting with
    currently is to make a game for my kids to play. One of them is visually
    impaired (read as blind), so sound and touch are the major play options.

    I selected the ISD because of the simplicity of interface, and maturity of
    the product. From what I have read, the early ISD's did have "click
    problems", but there were work arounds...and those are resolved in the newer
    products. I selected the ISD4000, because i am currently using an ISD1110,
    and I hate wasting pins for the address space :) The SPI interface on the
    ISD4000 looks really promising. This will additionally be my first surface
    mount components project, so that should make it a joy also. :)

    basically, the game is kind of like a reverse laser tag...a virtual maze,
    that will send different sounds to let you know where the walls are. Uses IR
    proximity detection to let you know when you get close. That way, you can
    moved the "walls" around easily.

    The ISD1110 project was a clicking location and alarm system for VI
    children. You put an emitter on the parent, and a "sensor belt" on the
    little one. The clicker sounds every few seconds, to let the visually
    impaired child know where the parent is (beats having to wear squeaky
    shoes!). there are 4 sensors on the belt, one of the front, one in the back,
    one on each side. The tone changes depending on the orientation of the
    child, to the parents emitter (so the child knows if they have turned and
    are walking away, or towards the parent). Using pretty low power IR. If the
    child gets out of range, an alarm goes off (not that anyone would ignore
    there child, but because kids do the DARNEDEST things).

    Eventually, I plan to offer these in public domain, and to the American
    Federation for the Blind. So, if you must steal the idea and make a product,
    at least send a donation to the AFB. ;-)

    My other project is the dirt cheap braille printer, sent as another thread
    in this group...but that is on hold for the moment, as we have a manual
    brailler to get "up to speed" on.
