Glad you like it! Raspberry Pi and similar embedded systems are actually widely used, for example NAS, IoT and smart things. Many people asked if Node can run on Pi, so I figured it out and would like to share my discovery.

An unsensored and equal internet ensures a healthy and bright future for crypto. This guide may serve as an entry gate for other interesting projects made by creative community.
