I'm actually working on finishing a project I started over 10 years ago,
but it stalled when I needed to provide some mass-storage.  I built a
Compact-Flash card interface but never finished the file system code.

So now I'm using a PI3 to provide the file server features.  The PICs
are all 18F4585s with CAN interfaces and the PI has a PICAN2 CAN
interface.

I've actually bought a couple of PIC24FJ64GA004s (and breakout boards to
mount them on) to play with and learn about the newer families.
