Description

This project is about establishing digital communication with Free Open Source Software (FOSS) and low power Hardware. The main aim is not to develop "the one and only next big thing", but to give students a basic idea of what is needed to exchange data between computing devices and to show that it isn't that much!
The more people have an understanding of how to build a communication network, the more of them will appear on the scene - at least that's what I hope will happen. Knowledge to the people is the only thing that can break the monopoly game that currently dominates digital communication.

Questions to answer are:
-How to input data (keyboards)
-How to output data (displays)
-How to forward data (networking)
-How to do it in a secure way and what inevitably kills security

Hard and software of very first "prototypes" of communication terminals. One with an ATmega328, a 8x8 LED matrix and a Morse button and a second terminal with a Raspberry Pico, a 320x240 Display and a 3x4 keypad.

No quantum computer nor Blockchain needed to exchange encrypted data

Quick & Dirty "Prototypes"

In a video I am demonstrating two very basic concepts of text terminals, communicating via an infrared interface:
It is a bit of a "rant" about the current monopoly game on digital communication and a quick demonstration that less is more.
