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 &quot;the one and only next big thing&quot;, but to give students a basic idea of what is needed to exchange data between computing devices and to show that it isn&apos;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&apos;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.
