Ah! I didnt mean to show it off, just my desk is a mess..

Yea its a cyberdeck I am building with hardwired Atreus directly connected to pi zero gpios and using libuinput to make a software keyboard, which works amazing btw.

I am making it to init directly into getty without login (with busybox init), so it boots directly in usable /bin/bash in only 2-3 seconds, and all the available programs are simple python programs (ls, cp, mv, a basic line editor, touchtyping game, hangman etc) and the keyboard itself is a simple python program that basically scans the matrix and emits events to uinput. The frame is from plywood.

And I am trying to make it like a 'scavenger hunt' experience for my daughter, I will put special codes in various places in the programs or on the file system with different difficulty, and I can challenge her to find them.

The goal is to have < 50$ scavenger hunt computer kit (thats why I cant afford teensy or something)

This is just the prototype to see how it feels to write code using line editor, and also to test the effect of thinking of the keyboard as a program with a nested for loop, on her thinking about 'what happens when you press a key'

    for r in rows:
        send(r, 1)
        for c in cols:
             v = read(c)
             if v == 1:
                  # (r,c) is pressed
        send(r, 0)

I just uploaded those to show you how it looks, but again, its just to test the software and the screens size:
