Many Cyberdecks that use Pelicases mostly use the Peli 1300 case, this cyberdeck takes it one step further and integrates everything into a super-compact Peli 1200 case. This shoebox sized unit easily fits into a backpack with room to spare. Official Raspberry Pi 7" touch screen. This unit is all about plug'n play, use the internal powerbank to power the unit, or hookup an external power source between 9-36V from which the internal powerbank can be additionally charged.
This log entry covers the various operation modes that are currently being taken into account in designing the power routing and switching of the unit, as well as the usability and accessibility of the communications interfaces.
To operate the unit, several operational scenarios have been defined and have been separated into user modes and power modes, which can each be combined with each other.
User is in close proximity to the unit and interacts directly with the touch-panel
Remote mode - controller
Remote mode - (controller) is intended to be used when the user cannot access the unit directly and is closed, but is still in close proximity to the unit. For this purpose it is foreseen to design a small hand controller/handheld unit with a simple dot matrix LCD display to view frequency/mode/GPS info/altimeter/time/... This mode can be used when the unit is in a backpack for example or located in a vehicle without direct access but still required to be operated.
Remote mode - Ethernet
Remote mode - (Ethernet) is foreseen to be used when the unit is located relatively far away from the user (>10 meters). In this case an Ethernet link is established to the unit via a network cable and all unit operations can be carried out and monitored via a remote computer. Use cases include remote spectrum monitoring for example.
In the remote modes, the initial setup consists of opening the unit, configuring the desired power mode and then powering the Raspberry Pi. The screen does not need to be powered, saving energy. The unit can then be closed and is ready for remote operations.
Any of the above user modes can be combined with a power mode below.
Run on internal power
Run on 5VDC external power
Run on 9-36VDC external power
Run on 5VDC external power + charge internal powerbank
Run on 9-36VDC external power + charge internal powerbank
Run on 5VDC external power + charge internal powerbank from 9-36VDC input
Run on 9-36VDC external power + charge internal powerbank from 5VDC input
Shielding has been added to the inside of the unit using aluminium foil tape. The backside of the frontpanel makes contact with the aluminium tape strips that extend over the edges of the panel frame. An opening was left in the shielding for GPS antenna at the top.
Bench tests indicated an active GPS antenna placed under the top of the Cyberdeck acquired plenty of satellites with good signal strength, hence the next step was an internal GPS module.
The active patch antenna and corresponding NEO-6M receiver PCB conveniently had exposed PCB pads which were used to solder the 2 together forming a stack. An SMA connector was additionally soldered to the exposed pads on the receiver board to facilitate an external antenna when the unit is being used inside a vehicle for example. After some brackets and screws the unit is ready for integration.
2x M3 inserts were inserted into the inside of the panel frame and secured with bolts and locking washers. (Note the white silicone in the background for the waterproofed N-connector feedthroughs, maintaining the case's IP-rating).
