One thing I found particularly difficult was being able to access each of them via SSH without my usual router that I‘d have at home, let alone the lack of internet access (access was available but naturally very stretched at an event like this).
I've found a very handy pocket sized solution to my problem - the FileHub from RAVPower. In a nutshell it's a portable router that allows you to connect your devices on the move - but it also offers a load of other features that will help make PiJams a hassle-free experience.
Lets run through my new pocket-sized pal...
