Source for 16ch datalogger with Atmel AVR needed

[panalog9]

Does anyone know a good source for a 16 channel datalogger based on an AVR ?

I'm certain it's been done before, and rather than reinvent the wheel, something like this would give me a good start.

I'm thinking of using an AT90S2313-10 with a pair of m@xim m@x186 a/d chips and a 64mbit Atmel serial dataflash for storage. Probably add on a Dallas DS1302 or 1305/6 for a RTC.

I've never done mixed digital and analog before, so I'm reading up on the caveats for the pcb design.

Any ideas ? Comments ?

Wow - no responses ? No-one has any information on dataloggers or AVR ?

How about mixing digital an analog signals on the PCB ? I'm learning, but experienced hints are always welcome.
