Egret's Hidden Laptop Computer
|
|
We have cut a hole in the back of the nav station
cubby. The laptop is mounted on an aluminium panel. The panel rests on the
lower edge of the hole. A 3/4" teak block is attached to the front
edge of the panel and is suspended from the front edge of the cubby by a
pair of barrel bolts.
|
Here, the barrel bolts have been retracted and
the front edge of the laptop is dropped down, allowing access to the CD-ROM
drive.
|
|
|
As the front edge of the laptop drops down, the
rear portion pivots on the lower edge of the hole in the rear of the cubby.
The aluminum panel has notches that engage with vertical tabs in
the corners of the hole. The DC-to-DC power supply for the laptop
can be seen at the upper right.
|
Now the laptop and its panel have been lifted out
of the cubby and placed on a pillow on the nav station desk. All the connecting
cables are clamped to the panel for strain relief and fitted with ferrite
chokes to reduce radio interference.

The laptop is connected to an
inkjet
printer located forward of the navigation station.
Egret's laptop, GPS, VHF, Radar, 1-wire sensors, and APRS TNC are interconnected
via a
"Serial Box."
