The housing has been designed, and the injection-moulding tools are in the process of being fabricated. We expect the first shots from the injection-moulding to be received in early April.
Industrial design for the housing was by ProEn, South Australia. ProEn are also organising the manufacture and testing of the injection moulding tools. Injection moulding will be performed by Garon Plastics, South Australia, after the initial test phase, which will likely involve the tool-makers in China producing a test-run of perhaps 100 parts, that we will use for the first stage of the DFAT pilot, while waiting for the tool to be shipped to Australia.
The housing requires a BS154 o-ring to provide the seal between the two halves of the case. We currently source these from Statewide Bearings (http://www.statewidebearings.com.au/branch-locations/south-australia/) for AU$0.53 each in lots of 100.
The following images show 3d models of the housing, as well as how the PCB and antennae cabling will connect.
Perhaps the greatest challenge with the housing is to ensure that it will be IP65/66 rated, so that it can endure tropical-maritime and hot/cold outback conditions, while still being able to reject enough heat to keep the internal ambient temperature below 70C for proper operation of all components. This requires that the cases be light in colour, and ideally, have an optional shade fitted if they are to be used in full-sun situations.
