It's not
to have the "eierlegende Wollmilchsau" (German term for an
all-in-one
device suitable for every purpose). No, the essential point is
the design
of the interfaces and their usability that the device has. As
far as I
can remember over all previous discussions within this list,
this point
never had been expressed when describing the benefits of the
GTA04.</font>

Sounds as "the unix way": one thing, do it well, with clearly
defined and accessible interfaces. Only, it _would_ be nice if it
laid eggs. <br>

We can _at least_ design some Lego-compatible knobs on the backplate
or sides.<br>

AA-batteries have been mentioned more often. I'd also like that;
three of them supply 3.6V and are easily sourced up to (to my
knowledge) 2900 mAh for NiMH. Never saw li-ion AA batteries at 1.2V
though but didn't spend much time searching for them. Alibaba goes
over 3000mAh for AA batteries, but I imagine them "incorrectly
labeled" or having a larger diameter than usually.<br>
<br>
Are we bound to 3.7V for input, by the way? Most telephones I know
use it, but not all our components use 3.7V so we have to step up or
down anyway.<br>
