Helping my son with a highschool CDAT project. (And at the same time aid the Ethereum project: community awareness). We would like to build a node on a "reliable" single board computer, then scale it 10x or larger. The project would teach: hardware, software, and general Ethereum knowledge. Currently, looking at the lattepanda, and/or cluster concepts in our current research. The ultimate vision is to have a fully functional compact design which will give system status information via remote access. Any advice, would be greatly appreciated.
