The Raspberry Pi is a series of credit card-sized single-board computers developed in the UK by the Raspberry Pi Foundation. They are tiny computers often used in Hackathons to make cool stuff.

Matt: Why would anyone want something like that.
Zeeshan: Lord knows but it won a prize at this Hackathon.
