Andrew Mulholland wrote up a great tutorial on how to create a networked classroom of Raspberry Pis using Raspberry Pi-LTSP.
Raspi-LTSP is a utility for setting up infrastructure required for a classroom set of Raspberry Pis. Its main features include
- Network based user accounts – A student can log onto any Raspberry Pi in the classroom and have access to their files. Their files are stored centrally on the server.
- Centralised master operating system – All the Raspberry Pis boot a single master operating system from the server every boot.
- Automated work submission and collection system – A teacher can easily collect work from students digitally for marking without the need for printing.
Raspi-LTSP requires a wired Ethernet connection between the server machine and every Raspberry Pi. Infrastructure for this is usually already included in ICT classrooms but if not, a simple network is relatively cheap and simple to set up. On top of this, an old desktop or laptop is required to run the server. It does not need to be powerful as will be running Ubuntu Linux, a very lightweight operating system.
