In order to help documenting how people learn, we imagine minimalist infrastructure such as paper notebooks or very simple computers to record ideas, read, think, communicate between peers using minimal energy & program from the ground up. 

The idea is not to solve poverty, ecological crisis or political inequity with technology (solutionism) but to recognize how these challenges might also be addressed from the perspective of minimal yet powerful technical infrastructures at human scale, which are understandable, buildable and limitable by anyone.

These are propositions ( a complex puzzle needs a picture on the box ):

** [[Zero notebook]] **

A documentation-oriented paper notebook.

** [[Zero board ]] **

A __sub-dollar__ concatenative ([[forth]]/[[fonc]]) chip in a rugged USB key form factor, with micro-screen, GPIO, battery, network, radio, text-only shell, remote terminal & TF storage preloaded with Sugar [[https://wiki.sugarlabs.org/go/Sugar_on_a_Stick|on a stick]] & live [[https://www.debian.org|Debian]]


** [[ Zero host ]] **

Zero board inserted in host keyboard + display OLED/TFT + outputs :ntsc ::vga :::videoproj

** [[ Zero cam ]] **

Zero board with a small camera

** [[Zero hub]] **

A __few dollars__ linux box with big storage (wikipedia, wikimed, stackoverflow, hacker news...), high-speed networking and graphics. 

Sugar, Proce55ing, ShaderToys, [[Squeak]], [[eToys]], Sugar, Scratch, Python, Forth, Smalltalk, C for children ... (non-exhaustive list)

** Peripherals **
  - Low-tech Videoprojectors (e.g. DIY [[https://dspace.mit.edu/handle/1721.1/29145|I/O Bulb]]).
  - PSU (power supply unit), Solar.
  - Low Tech screens
  - Input devices (e-textile / e-paper diy keyboards). 
  - Radio (LoRa, Sdr, Synth/Oscillo). 
  - Simple breakout boards (sensors, actuators)
  - Fabrication devices (CNC, Lasercutter, ...)
  - Tangible Interfaces for children (remake of TMG classics, URP, InTouch, CurlyBot ), Turtle that produce its own code while moving physically
  - [[https://en.wikipedia.org/wiki/Internet_0|Internet0]] Router

** Zero atom **

Programmable matter module composed of active biopolymers or other future active biomaterials. 

-> towards a programmable matter kindergarten (softmatter loose parts)

Tangible Asynchronous / Mesh programming (e.g. think of [[https://dspace.mit.edu/openaccess-disseminate/1721.1/72349|RALA]] / [[https://inst.eecs.berkeley.edu/~cs152/fa06/lecnotes/async.pdf|FLEET]] for non-electronic substrate).

Digital simulation in an asynchronous chip (e.g [[http://www.greenarraychips.com/home/products/index.html|GA144]]) bootstrappable by children.
