I apologise if this is not an appropriate place for this question. Does the Blender Foundation consider GSOC applications that are for add-ons, not core code?
To be more specific, my proposal would be for a python tool that connects Blender to various open source microcontrollers (e.g. Arduino) to allow creative (and ideally easy) use of data from the physical world in virtual worlds.
To be even more specific, I have already started work on this tool, if you require further clarification. Current documentation here.
In short, would an application along these lines even be considered, or are there strict core code stipulations?
