SHELVES

     Shelves are used to mount other components on.  So far, Leaf has three.

    The  lower shelf is used to hold the microcontroller and associated parts.  It is built by placing a 3/4" x 3/4" angle  (.055 thickness) across the front and the rear of the frame.  I then used a 6 mm thick piece of Sintra plastic to form the shelf.  6-32 screws and nuts were used to attach the angles to the frame and to attach the shelf to the angles.

   The angles and shelf were cut to a 12 3/4 inch length.  This leaves 1/2 inch in each corner to run wires up and down inside the vertical angles.

   The top shelf (on top of the frame) is a piece of aluminum attached to the frame with screws.  It is a convenient place to mount the camera microphone and speaker until I figure out something better to do for them.

   Lastly, there is another shelf mounted behind the laptop.  This shelf currently holds a USB hub and the CMPS03 compass. 

Note that there is an aluminum enclosure attached underneath each shelf which provides a nice hiding place for all the excess wire lengths of the USB cables, microphone and speaker wires and laptop recharging wire.
