well like Nik, I managed to get hold of acouple of raspberry Pi's , took me full year of begging the supply houses but they are here.
If you are using the Pi board or its add on the GERT Board or arduino boards you need something to mount them in/on.
I was trolling thro the kickastart site (useful for funding you ideas into production !) and came across the SPACE STATION set up.
take a look at the Kickstart site and the space station site for more details
I have no commercial interest in the company except that I made a donation to start the production.
