Does that sound about right?
imho YES!
Can you see the potential?
Feel the extra degrees of freedom!
Smell the creative mind exploding with (litterly) out of the box ideas ...
talking about box...
Another shield I would like is a shield that acts like a box. No need to screw the arduino on some bottom, just plug in to the boxshield (tm) and ready.
The box-shield has the famous pin layout in its cover that can be plugged on top of an Arduino stack of shields.
Put the cover over the box and done.
One size cover fits many sizes of boxes. And there are many coversizes - MEGA, UNO, DUE, TRE, QUATTRO etc*
"Of course they come in any colour as long as it is black" ;)**
- A QUATTRO is a cover that can hold 4 UNO-stacks in one box.
