The Ground Sphere Test Transmitter will transmit radio signals on 915 MHz
Be mobile so that the terrestrial tests can be done by adding distance between the transmitter and Ground Sphere receiver
The Ground Sphere Test Transmitter will only require simple tools (screw drivers, pliers, wrenches, etc) for assembly
The Ground Sphere Test Transmitter will take no longer than 60 minutes (threshold)/30 minutes (objective) to assemble by an average maker
The Ground Sphere Test Transmitter kit will cost no more than $15 (threshold)/$7.50 (objective) to ship by ground across the USA.
The Ground Sphere Test Transmitter software must run on Windows 7 or Windows 8 (32bit or 64bit)
The Ground Sphere Test Transmitter software must ship in a Windows installer
The Ground Sphere Test Transmitter radio must connect to the ground station computer through a commonly available port (for example: USB)
The Ground Sphere Test Transmitter hardware should minimize the opportunity for mechanical failures (from things such as broken connectors or a lack of strain relief)
The Ground Sphere Test Transmitter design must enable the production of at least 30 +/- 5 v1.0 kits by volunteers in one or more makerspaces
The materials cost must be under $75 per kit.
The project budget (covering three prototypes) must be no more than $200 (threshold)/$100 (objective)
Version 1.0 of the Ground Sphere Test Transmitter will be ready for kit production no later than Feb 14, 2014.
