[sdiy] Which programable chip?

[Jason Proctor]

>That's it... there's the problem. I need 8 analog ins and 8 analog 
>outs and all the switchy bits in between.

the regular Arduino has 6 10-bit 0-5v analogue inputs. other 
varieties have more. the new Arduino Mega has... 16 analogue inputs, 
not to mention 56 digital pins and 4 hardware UARTs (gulp).

then slave up a TLV5610 for 8 analogue outputs.

(not that i'm advising the Ard for any particular reasons other than 
it's a great way in to microcontrollers and i've had success with the 
platform.)
