Software defined radios that can work in extreme conditions (like during or just after a giant disaster), an IoT kernel that does useful work in a mesh network without a back haul, a personal 'internet radio' that can stream your home market AM/FM stations to you anywhere, and computer system to teach the mid-levels of computer science between programming and and database design.

Where can I read more about your SDR project? Is it a transceiver or just for monitoring communications? I'm a HAM (KK6BXK) and starting a website (http://www.survivalscout.com) that plans to cover this type of stuff. I try to link out to neat projects like this

Could you explain more about the computer system to teach computer science ?

Would it be like an iron python notebook ?

In my opinion, there is a gap between what you can learn on an Arduino type environment and a Raspberry Pi type environment. When I started using Cortex-M level processors (32 bit, very simple MMU (protection only) I realized that it could be the basis for a "PC/AT" type system where you could explore everything from a simple monitor based operating environment (think MS-DOS or AmigaDOS like) through to a self hosted set of compilation tools. The hardware is pretty easy (there are lots of different ideas in this space) but the curriculum is currently still a bit weak. So with the addition of a simple FPGA based frame buffer I've been building a system that can be used to teach a student computer systems.
