right now I take the test outputs and run them through dieharder.
They are disgustingly big (and somehow don't compress very well:-) but
it should be possible to upload them somewhere.

But again, a dieharder run needs at least about 14 GB; more if one of
the more demanding tests turns out "weak" and needs more input.

Both the RasPi/Arduino headers and the boards we've built use standard
100mil headers, so they can be easily connected using jumper wires.  The
only problem may be voltage levels; either rely on the input protection
on the host side or use a voltage divider---either a fixed 3.3k/6.8k
resistor pair or a 10k potentiometer should do the trick for 3.3V.

And of course, when it comes to the RasPi and my board, there's USB.


Cheers,
