    I need to make a simple sound module that can record at least 60 seconds of sound and then be put in a loop so it can run continuosly. It does not have to be re-recordable. Can anyone help me?

    hi,
    I'm interrested too by this kind of components i found the ISD2564P from Winpond , I' m waiting for it from my local distributors. The datasheet give some test circuits.

    Winpond do a lot of this kind of components

    waiting for your solutions

    Hi JP,

    My knowledge in this area is VERY limited. I don't know if I need a CODEC chip, a ChipCorder, or what. I think there must be a very cheap way of making these, I do need at least 20, but I'm lost where to start. I have one by an unknown manufacturer and all it is comprised of is a board with a general amplifier and a small 8 pin IC that I cannot read the numbers on, no other electronics. Could the IC be just a memory chip that can run a program and play the sound?

    Thanks for the response.

    Aplus (Taiwan) has some of such chips.

    Why not try buying some of those greeting cards that ley you record a little message then play it back? With a battery attached they must be able to do what you need althoguh it might need an amp.

    Or alternatively, this is a complete assembled PIC controller on a PCB that can play 30/60 seconds of sound (depending on sample rate) and has a tiny amp built in. Having a PIC on-baord (an open source firmware) you could make it control your whole device;

    Hi RB, Thanks for the info.

    I have looked at the greeting cards with recording capability but I can't get them to play continuosly. I will have to research the PIC controllers and see if that will work. The robot brain was interesting but pricey.
