I've read a ton of your posts Jonny, and I can't tell you how much help they have been.

I'm trying to avoid using a PC for the sound control and I'm trying several other approaches. First, each character will be using a WinBond ISD4004 chip to store their voices. It holds about 16 min of sound. I'll be wiring one up this weekend to check the sound quality.

You are correct, I'm going to trust that the clocks stay in sync during the two minute scene. If not, I'll have to work out a different approach. I was toying with the idea of having a master DS1307 clock, and sending out a sync pulse at the start of the sequence. Any thoughts?

Because of the distance between the characters, I'll be using 433Mhz wireless for communications. I already have this wired up and it's working.

As a side note, I'm starting to wonder how much I can tax one single SX28 before I have it doing too much. So far, I haven't hit that wall yet. I have one chip, in my master controller, running an LCD panel, 433Mhz Receiver, transmitter and keypad. 

Thanks for posting the pic too, very clean design! Are you making your own pc boards at home? I've seen several kits online and was debating on trying them.
