One of several single-board computers. The Raspberry Pi is an ARM computer that typically sells for less than $50. Generally is runs a derivative of Debian.
Others such as the Pine64 are less popular but even more open.
Additional information
- Installing Debian Backports on Raspberry Pi - particularly useful for running NNCP or Yggdrasil on a Pi.

Filespooler lets you request the remote execution of programs, including stdin and environment. It can use tools such as S3, Dropbox, Syncthing, NNCP, ssh, UUCP, USB drives, CDs, etc. as transport; basically, a filesystem is the network for Filespooler. Filespooler is particularly suited to distributed and Asynchronous Communication.
This page is intended to describe how to run Debian’s backports on a Raspberry Pi. Backports is Debian’s way of building newer packages for its stable releases. I intend this page specifically to help people run the Debian packages for NNCP and Yggdrasil, both of which are maintained by me, John Goerzen.
NNCP lets you securely send files, or request remote execution, between systems. It uses asynchronous communication, so the source and destination need never be online simultaneously. NNCP can route requests via intermediate devices – other NNCP nodes, USB sticks, tapes, radios, phones, cloud services, whatever – leading to a network that is highly resilient and flexible. NNCP makes it much easier to communicate with devices that lack Internet connectivity, or have poor Internet.
Old technology is any tech that’s, well… old.
Yggdrasil is a Mesh Network that is fully Encrypted and provides an IPv6 IP on the network to anyone.
