Equipment Packaging

High-tech equipment is exciting indeed, but there are all sorts of problems associated with installing a wide range of delicate components onto a mobile platform that has to withstand years of heavy shock, rain, temperature extremes, and human abuse -- yet still be easily serviceable. Fortunately, circuit fabrication techniques have evolved to the point where the silicon innards of most electronic devices are extremely rugged... but that does not necessarily include the I/O devices, disks, frequency-determining components, and so on.

There are three major equipment bays in BEHEMOTH -- the console, which unfolds completely for service; the RUMP, with an access cover to a shock-mounted platform; and the trailer, which contains all radio communication gear as well as a secondary operating position. The latter two are constructed of CSPC (cellulose core, silicon matrix, polyester-filled composite -- otherwise known as fiberglass over hot-glued corrugated cardboard). This material is light, waterproof, cheap, and easy to build in any arbitrary shape; learn how here.

The console is where most of the hard-core action is, and it is a complex articulated structure shock-mounted to the frame, protected by both a custom fiberglass fairing and secondary waterproofing layers. Releasing a succession of push fasteners turns the entire affair into a workbench, with easy access to every subsystem and the back of the control panel. Boards that require frequent work are themselves hinged, such as the "nexus" board that carries all random logic associated with the BCP.

To a somewhat lesser degree, the RUMP and trailer offer similar access to internal equipment. But as we move aft, there are more and more RF and power devices, necessitating a different class of design in order to keep noise to a minimum. Suffice it to say that every component is either a custom assembly or a repackaged commercial product, requiring some special attention to keep it working and fixable during the unknown miles ahead.
