We present our ongoing work building a large Raspberry Pi cluster. One Raspberry Pi can be purchased cheaply and has a low power consumption. Despite of the lack in computing power we see several interesting use-cases for our cluster. One of these is “Bobo” which brings a company like Google, Amazon or alike inside a box that is designed sustainably using material that anyone can obtained from any store. As a result, the anyone can experiment with Bobo running a similar set of services like any other cloud computing service offering company.
