Jim,

We're thinking along the same lines.

I'm envisioning a board about 3" x 5" with mounting holes for the gumstix as well as in the four corners :-)

I ended up doing a custom pcb for my current project in a configuration very similar to this.   Seeing the result is what gave me the notion to do something a bit more general purpose for prototyping future projects.

The dipstix idea is cool for "one off" protos on 3M solderless breadboards, but doesn't fly if you need to build more than one or require mechanical integrity.

We've been evaluating gumstix for an industrial application. While
we've been mostly happy with its functionality, my vote today would go
against using it.

Small size is good, and the size of the current board for some
applications is a real plus. For ours, its a pain in the a**. While its
ok to have to solder bits off the side and find an appropriate solder
track to get VCC from etc. for a one-off project, for even modest
volume deployments this becomes a deal breaker. The shear labor cost of
doing this (in time and/or money) and the hobbyist appearance of the
result means its probably better to just buy a pc/104 board.

My suggestion would be to think about a version of gumstix that may be
3-4 times as big but brings out the functionality in pads that accept
common connectors, already has a reset switch and a couple of leds and,
as trivial as it may sound, has 4 mounting holes of a size that
accommodates common standoffs and screws.

Such a board could serve as a prototyping board but would have utility
beyond that, and would open new markets for what is otherwise a really
good product.
