There are no doubt better lists for hardware engineers, but we
probably have a few here.

I think you would need to say what it was about these 40 boards that
did not meet your requirements before I could say anything useful
about what might satisfy you.

Emdebian welcomes help to make it to being an actual distribution you
can use - we're not quite there yet. Note that Embedian is a(n
unhelpfully-named) company in Taiwan (nothing to do with emdebian).

You are in the right place for any such activity.

Wow - do you have web-pages on this project? It sounds quite something. 
I don't think we've had any debian self-build motorhomes on this list

All the ones I know have a subject focus: bikecurrent (bicycle
eletronics), speleonics (caving electronics/low-frequency radio),
lart, balloonboard (specific SBCs), TAPR (radio ham stuff),
candlepower forums (lighting), SBMCC, Eastern MHC  (self-build
motorhomes), and so on. I do not know any for general EE's, although
there no doubt are some.

I just gave a talk on this at FOSDEM. There are at least 5 things
people mean by 'Open hardware': Documented interfaces, free firmware,
VHDL designs, freely-manufacturable PCBs/devices, and (I discovered at
FOSDEM) a power management software infrastructure.

The best collection of this sort of info I know of is the OpenTech CD:

I am also interested in this area, having been making Open Hardware
SBCs since 2002 (lart). I now do it full-time (see balloonboard.org).
