1st Mockup

I thought I'd try and see if the NSLu2 fits on my chassis.
Looks like it will fit. A couple of concerns at the moment is I need a way of mounting the NSLU2 that will allow me to remove it easily but still keep it in place during use. The USB key hangs over the side of the chassis, it looks a bit vunerable, I guess I could either get a smaller key or move it somewhere else.

The weight needs to be over the ball caster else it tends to tip, I'm sure the positioning of the batteries can be used to balance the robot.

The last photo shows a very rough mock up to try and establish the size of the circuit board. I've temporarily put 32mm spacers on the chassis and cut out some cardboard (courtesy of Mr Kipling, mmmm cake!!!). I've ended up with a 125mm disc with a 98mm x 30mm slot. One interesting thing I've noticed is the power socket on the NSLU2 is very close to the height of the board, I'm sure there's some mileage in mounting a power plug on the board.
