Lately I have been back and forth to Hackathons via Plane, without access to my full electronics kits due to having to travel light. I really wanted to have something that I could build POC's on, and could never decide between Raspberry Pi, or Arduino. In the end I built this little Briefcase that contains a RPI, LCD Screen, a GertBoard expansion board (Contains an ATMEGA section) And a few other useful bits and bobs. This is just perfect for Hackathons, so long as airport security doesnt freak out!
