OH Boy.

This would be biting off more than I can chew I think.

First, I thought some of the ISD chips can be PIC controlled as they relay only on high/low pulses? No special programming required.

Second, I don't know if I can fit a large enough PIC and/or ISD chip in there. I need. at a minimum, 3 inputs, four outputs for the sound, 10 outputs for the LEDs. In that very small prop would also have to be batteries and a small speaker.

Third, the ISD must be better than a phone line surely? The frequency is higher according to the specs.

Fourth, I'd only want sound play-back in the prop so the actual recording would be done outside of the prop and the chip put into the prop. This is to further keep down the components in the prop. Don't need anything extra for recording.

Fifth. It would be all .WAV files recorded.

I looked at the link and the link off that to the sound PIC. That PIC seems like it would be physically too large for my application and even if it weren't I don't think it can handle all the other duties for input and output. It looks pretty dedicated, but I'm looking further into it just in case I'm seeing just the surface of the thing.

Thanks.
