Once we have cut our teeth on the VLF based SID detector network and have the Radar Back-scatter meteor detection system up and running how about this as the next Flamsteed Radio Group Project?
How important is the Banana?
This looks absolutely fascinating. Have done some further digging on this, and the website where you can sign up for further information is here: http://cosmicpi.org
Definitely something I'd like to get involved in. I've just got hold of a Raspberry Pi 3, specifically for it's built in wireless LAN and bluetooth capabilities... so, yes, this project is certainly on my list of things to do.
It looks like the schematics and PCB layouts can be downloaded from here http://www.ohwr.org/projects/cosmic-pi ... but I may wait until the crowdfunding is available.
