Raspberry Pi's run off of the Rasbian operating system which comes in many different "flavors" (versions). N00Bs, the most common flavor can just be unzipped onto the mini-SD but other projects made need to have an operating system "flashed onto it". The Makerspace does this using the software, balenaEtcher.
When the Raspberry Pi is returned make sure the borrower has copied any personal files off of it before reformatting the microSD card. By reformatting the microSD card, you're removing all the data from it including the operating system (e.g. N00BS, RetroPie).
The RetroPie project turns a Raspberry Pi into a retro-gaming machine that can emulate older video game consoles such as the original Nintendo, Super Nintendo, Sega, Game Boy, etc. While RetroPie itself is perfectly legal, the games in the form of ROMs are more of a gray area. The library is able to use its RetroPie set up only because of its status as an academic institution and the Fair Use Act.
Absolutely do not give patrons our ROMs, this would be a violation of copyright law.
NOOBS (New Out Of the Box Software) is a basic Raspberry Pi operating system. It contains the essentials such as a text-editor, an internet browser, and a learn-to-code program called Scratch. The installation process is (fairly) simple:
Scratch is an easy-to-use, graphical programming language that introduces users to computer programming. Blocks, not text are used to build simple computer programs and animations. Scratch comes along with the N00BS operating system but is compatible with most Rasbian flavors.
