I'm not really sure if I really need beefier analogic HW, but I've
something to play with where I'd see a pic as a better coprocessor than
the atmel (dsp and pwm?).

The Yun is very nice since at least it comes with a Linux part that is
ready to use, but I really would like to feel comfort and have fun and
be able to have debian there.

One of the things I was planning was driving pwm at 500KHz being able to
adjust the frequency in step of around 500Hz every 500ms.
I still haven't thought about how much RT math I've to do in those
500ms, a dsp could be welcome. But yeah, I'm daydreaming.

Thanks, a good place to start.

Just the list you sent me will keep me busy for months ;)

Actually I saw many boards that have interesting prices and hw specs, I
just have to check which one has the best linux support so to make it
easy to install debian.

I just have to test koa on node.js and I'll find some time to chose and
by one.

thanks, the linuxgizmos list was really a good place to start, it gives
me some hope I'll have fun.
