I will walk you through the steps to set up a full Ravencoin node on a Raspberry Pi running within your home network. A Raspberry Pi node is one of the cheapest options for a Ravencoin node (under $75) and consumes around 3 Watt when running the node and no peripherals are attached to it. The guide runs you through buying and installing hardware, setting up the operating system ([https://www.raspberrypi.org/downloads/noobs/ using NOOBS]), installing the node, and setting up security. Setting up security is highly recommended because you are opening a port to the outside world and you want to make sure it is only used for Ravencoin. Also, as there is no working Raspberry Pi graphical user interface for the Raven Core wallet, you will have to set it up through commands in the terminal. For each step, I will try to explain what you are doing and provide command lines that you need to execute. I will provide links that 1) don't require you to compile the node (which takes about 2 hours if it doesn't crash halfway), and 2) a direct download of 1.8GB of the blockchain, so you don't have to download it from other nodes in the network. These steps likely save you days in getting the node up and running.
