Encasing it in a LEGO brick would make it far more resilient and reduce the chances of
dust, etc, contaminating the circuit board. Further, if it were pluggable into regular
LEGO bricks, the model would not *demand* construction oriented towards carrying a
delicate and loose load. Although such models can be interesting and challenging to
build, they do not represent every possible robot design. Finally, as I stated
before... it's about modularity. LEGO bricks plug into eachother -- physically. They
hold together to an extent by this force alone. If one wanted to use a Handyboard
exclusively for LEGO projects, and wanted it to be convenient to disassemble,
reconfigure on the fly, etc. this sort of thing would make it much easier to work
with. I fully expect that the preceeding comments may produce a swarm of "but you
should carefully design your model first!" responses, and let me just say up front that
I understand the importance of this. LEGO is, however, a toy. Is it criminal to want
to just play with it?

Of course, any enclosure designed for the Handyboard should have room for Fred's
expansion board already accomodated.

| There are two very easy methods of making LEGO compatible 9V connectors. 1. Use Dacta #779897 9V Connecting Leads (3 pieces) @ $12.25. Cut the leads to the appropriate length for your use.
