The challenge is to design a case for the Raspberry Pi computer with these qualities:
* # Waterproof to 3 metres.* # Maintains the system-on-a-chip at temperatures not exceeding 50C when operating at 100% CPU utilization in 30C water for 1 hour.* # Able to protect the Raspberry Pi through a drop of 2m to a concrete floor while powered-on and operating.* # Provides waterproof connections for power, USB, ethernet, and GPIO header cables.* # Permits viewing of the Raspberry Pi LED POWER and OK indicators.* # May be securely mounted to a flat surface such as a plywood board.* # Either uses no energy, or uses 5 VDC at up to 500 mA for active systems (e.g., cooling, indicators).* # Can be opened to provide access to the SD card slot and SOC in less than 3 minutes, while the unit remains in operation and attached to a mounting surface.* # Can be built for less than $40 per unit in a 50-unit production run.
