  1. Definition of Digital Education ("education-of" or "education-with" ?)
  2. Evaluation criteria for e-didactic tools, media and methods
  3. Parent participation in digital education

Two topics of PRAXIS :
  1. Evaluation and extension of "Computer Science Unplugged" curricula

Digitale Fibel :: Project Participant Interaction Space 

Daniel :: Hello world !
Gero: hi
Akif:: Hey everyone! (:

Fibel :: Architectural primitives

Hardware is Raspberry Pi, OS is Raspbian which after booting automatically logs in the user fibel whose .bashrc specifies to launch xinit whose .xinitrec specifies to run chromium
Frontend is running in chromium which loads index.html which loads all the rest.

Interaction between backend services / sensors and frontend takes place by means of websockets. Every backend service pipes it outputs into pipes located in /dev/fibel, these pipes are created by bunch of gwsocket-daemons launched at startup, config file for service2port associations is in /etc/fibel/sockets.

All necessary frontend code for dealing with sockets is in js/sockets.js

Session 2 - Constraints

Of constraints, their usefulness and influence they exerce on design and designers of the Primer artefact


Think about all possible and impossible constraints (and obstacles) which could (and many of them also will ;) during the creative process.

Try to categorize these constraints into 3-5 main categories.


Constraints are designer's (strongest) allies.

Categories of constraints which an artefact like digital Primer is to be a subject.

Raspberry Pi Kiosk Tutorial

The Raspberry Pi has proven itself to be a great computing device while keeping cost as low as possible. For less than $40 you are getting a great little device with its 64-bit ARM processor. This made me think, would it be a good idea to turn the Raspberry Pi 3 into a kiosk?

The software that you'll need

A list is not even needed, because you only need three things: Raspbian Jessie Lite installed as the OS, the X11 display stack installed and the Chromium webbrowser installed on the Pi.

Why Chromium

Chromium is the open source variant of the popular Google Chrome browser. It has great potential for this project because of the --kiosk flag. With this option you can create a full-screen browser window inside your empty X11 session.

Installing the X11 display stack

You can install the X11 display stack on your Raspberry Pi with the following command:

sudo apt install xserver-xorg xinit

This will install the X11 server on your Pi together with the X11 server initialisation program. You also have to run this command:

sudo dpkg-reconfigure x11-common

To select who's authorized to start the X11 server. Make sure it is set like this:

x11-common package reconfiguration

Installing Chromium

Just run sudo apt install chromium-browser to install Chromium on your Pi. It's literally that simple.

Writing the .xinitrc script

When you execute the xinit command on your Pi, you will see a terminal window instead of Chromium. To fix this, you'll need to write a file in your home directory called ~/.xinitrc. This file contains everything that gets run when the X11 server starts up. So, edit this file with nano (or any other text editor) and make sure it looks like this:

.xinitrc file with Chromium

Save it, and try running Chromium by invoking the xinit command on your Pi.

But... my window is not fullscreen!

It could be that your Pi shows black borders around the screen, which has to do something with overscan. Open your /boot/config.txt file (with sudo) and add disable_overscan=1 to this file like this:

Disable Overscan

Reboot your Pi and the problem should magically disappear! (at least, that's what happened to me...)

Starting X11 at boot

Raspbian comes with a built-in tool to configure your Pi: raspi-config. Run this command on your Pi and you will be greeted with a command-line dialog window. Go to option 3 and press enter:

raspi-config main menu option 3

And then go for option 2:

raspi-config boot options option 2

Press enter, go to finish and when the program asks for a reboot choose yes.

Once you have rebooted your Pi, you'll have to do one more thing to finish this project: finally starting X11 at boot! My method might be more sophisticated than needed, but hey: it worked for me. Edit the ~/.bashrc file in your favourite text editor and add the following to the bottom of the file:

if [ -z "$SSH_CLIENT" ] || [ -z "$SSH_TTY" ]; then
    xinit -- -nocursor

save the file and reboot your Pi. Enjoy your beautiful self-made Raspberry Pi Kiosk!

Load webpage from an URL specified in a file

A Raspberry Pi with the default partition layout contains two partitions: the OS partition, and the BOOT partition which is formatted in FAT32 and gets automatically mounted at boot. For example: create a new file in /boot/ called website.txt and put your desired URL in it. Finally to make it work you simply replace the URL in your ~/.xinitrc file with $(cat /boot/website.txt) and it should work! The thing is that you can actually see and modify contents of this file in Windows, since the BOOT partition is partitioned as FAT.

Hacks and Tricks

Some useful know-how for creation of Your own digital Primer.

raspi(usb)-raspi zero+inkyPhat hack

I just realized that a following hack could be worth trying:

1) we have the main PI with all pins already taken but with an available USB port

2) we connect the cheapest 5$ no-WIFI variant of RasPI Zero to the USB of the "main" PI, and we put the inkyPhat on this pi zero

3) wittyPi starts the main PI

4) power starts to flow to main PI's usb port, hence the small PI starts

5) the main PI can communicate with the zero in a sort of ethernet-emulated through USB, c.f. ... for example, an image to-be-displayed can be sent from the main PI to the zero

6) once the image is transfered and displayed on the inkyPhat, pi zero can communicate to the main PI that the job was done and halt

7) additionally, the main PI can shut down the USB port through which the zero was powered ... c.f. , if  that hub-ctrl.c will work than it is a hammer

8) when a new image is supposed to be displayed on the inkyPHAT, power flow to the USB port can be reactivated and steps 4-7 can be repeated

The idea is to counterbalance the deficit of GPIO pins on a PI with communication with "peripheral" zeros, which have a new full set of GPIOs, are small and cost 5$ a piece...

Raspberry pi 

Der Raspberry Pi (engl. Aussprache: ˈɹɑːzbɹi 'paɪ) ist ein Einplatinencomputer, der von der britischen Raspberry Pi Foundationentwickelt wurde. Der Rechner enthält ein Ein-Chip-System von Broadcom mit einem ARM-Mikroprozessor, die Grundfläche der Platine entspricht etwa den Abmessungen einer Kreditkarte. Der Raspberry Pi kam Anfang 2012 auf den Markt; sein großer Markterfolg wird teils als Revival des bis dahin weitgehend bedeutungslos gewordenen Heimcomputers zum Programmieren und Experimentieren angesehen.[1] Der im Vergleich zu üblichen Personal Computern sehr einfach aufgebaute Rechner wurde von der Stiftung mit dem Ziel entwickelt, jungen Menschen den Erwerb von Programmier- und Hardware­kenntnissen zu erleichtern. Entsprechend niedrig wurde der Verkaufspreis angesetzt, der je nach Modell etwa 5 bis 35 USD beträgt.

Bis Ende 2017 wurden mehr als 17 Millionen Geräte verkauft.[2] Die Entwicklung des Raspberry Pi wurde mit mehreren Auszeichnungen bzw. Ehrungen bedacht. Es existiert ein großes Zubehör- und Softwareangebot für zahlreiche Anwendungsbereiche. Verbreitet ist beispielsweise die Verwendung als Mediacenter, da der Rechner Videodaten mit voller HD-Auflösung (1080p) dekodieren und über die HDMI-Schnittstelle ausgeben kann. Als Betriebssystem kommen vor allem angepasste Linux-Distributionen mit grafischer Benutzeroberfläche zum Einsatz; für das neueste Modell existiert auch Windows 10 in einer speziellen Internet-of-Things-Version ohne grafische Benutzeroberfläche. Der Startvorgang erfolgt gewöhnlich von einer wechselbaren SD-Speicherkarte als internes Boot-Medium. Bei der neueren Generation mit dem BCM2837 ist der Start auch von einem USB-Massenspeicher[3] oder Netzwerk[4]möglich. Eine native Schnittstelle für Festplattenlaufwerke ist nicht vorhanden, zusätzlicher Massenspeicher kann per USB-Schnittstelle angeschlossen werden, beispielsweise externe Festplatten bzw. SSDs oder USB-Speichersticks.

Head-shaped tridecahedral (13-plane) wooden shell crafted by Chris Schmidts and filled with Raspberry pi 3A+, Seeed Respeaker (4mic circular array, ac108 converter; APA102 12-LED RGB pixel ring) enriched with UltraSonic Ranger System sending UDP packets to "active wall" installation by architecture student Akif Sari.

6-inch e-ink displays page 4. of McGuffey's Ecclectic Primer, a well-known Fibel of Victorian Era. Display is currently powered off and as such has zero carbon dioxide trace (hallo Gretha!) while still teaching Alphabet. To see more interactive e-ink setup please check the artefact CardboardFibel0.

Carboard Primer

(with Astrid Kraniger)
First functional cardboard-embedded artefact combining touchless gesture-based recognition (Seeed Grove Gesture Recognition Sensor PAJ7620U2)with an e-ink controlled by IT8591 board and some ANSI C coded  for the purpose of diagnostics of difficulties in acquisition of learning and writing (Leserechtschreibschwierigkeiten - LRS).

Diagnostics focuses on so-called "Rapid Automatized Naming" which is considered to be one among the most important LRS-predictors.

Visual content ("animal pictures") scanned from reedition of Lumen Picturae et Delineationis (Amsterdam, 1660, BE310).

Instead of a signature, this artefact contains a four-leaf clover (harvested in July) attached by duct-tape above the e-ink screen. Bottom of the cardboard shell is photovoltaic, making it possible to transform PappeFibel 0 or one of its derivatives into an energy-autarch ("eutark"; Hromada, 2019, AE49) digital education artefact.

TASK: Identify mismatch between visual and textual modality. 

INSTRUCTION OF USE: You interact with the device by moving Your hand in front of the Gesture Recognition Sensor (to the right from e-ink screen). Movement along vertical axis (up/down) maps to boolean (true/false, JA/NEIN) answers. Movement along horizontal axis (left/right) is used to browse the content. Rotation is used to switch between "learning" and "testing" mode.

CAVEAT: When changing modes of operation, new data has to be loaded into the buffer of the e-ink controller. This takes few seconds. Be patient. Breathe.

Touchless Ukulele

(with Anna Petzer)
This upcycled, portable, cable-less digital artefact combines touchless gesture-based recognition (Skywriter sensor)with a Raspberry pi 3a+ and integrated bluetooth loudspeaker.

TASK: Play with speed (time), position (space) and quality (suspense) of your hand movements. 

INSTRUCTION OF USE: You interact with the device by moving Your hand in front of the Skywriter sensor (above the sound hole of the instrument). Play the string to observe how the string vibration deforms the field measured by Skywriter. 


(with Nikoloz Kapanadze)
sonic is an experiment on the topic of screenless computers. what would our smart devices look like, and act like if they were not bound by the rectangular standard of the screen. sonic is a pair of headtracking headphones powered by a Raspberry Pi. the headtracking information is used to control a supercollider program that performs binaural processing. in  other worrds the spatial positions of sound sources are  decoupled from the listeners frame of reference. so to say the sounds stay in place as the user changes the orientation of their head. its like VR but for your ears not your eyes.

the device can also record stereo audio using the two microphones mounted on the two earcups. having microphones so close to where one's ears would be gives the sound a lot of presence.  the componnts are mounted on a pair of headphones that i've had for around five years now and the whole assembly is modular, meaning that faulty components can be easily swapped out.

sonic uses twin i2s mems microphones( SPH0645) for audio recording and a accelerometer+gyroscope+magnetometer(LSM9DS1) ic for head-tracking.

In a Praise Of Void

The stable "wall" is the very basis of land creatures and thus by "having responsive space rather than the linear presentation of the wall," the body is suddenly made aware of the situation it is in.

With the current housing crises and the reduction of the living space per person, the effect of the occupancy and void becomes more valuable day by day. But this concept, void, which can only be defined by its contrast: fullness, and which can change the perception of everyday spaces we are accustomed like a room, is not easily readable. This situation removes the concept from our daily practices and traps it in the dusty pages of abstract architectural books.

The project based on an example ordinary wall of living space offers a responsive space that will bring up a concept of void on the agenda in order to challenge perceptions of living space and physical context.

This exploration simulates an extreme architecture of responsive variable structure by suggesting a technological infrastructure with hypothetical material.

The narrative analyzes the benefits and limitations of these projects but avoids explaining the necessity and result of living in such a space. It remains speculative, is leaving the questions open for the next phases.

Over the years we’ve seen the Raspberry Pi crammed into almost any piece of hardware you can think of. Frankly, seeing what kind of unusual consumer gadget you can shoehorn a Pi into has become something of a meme in our circles. But the thing we see considerably less of are custom designed practical enclosures which actually play to the Pi’s strengths. Which is a shame, because as the MutantC created by [rahmanshaber] shows, there’s some incredible untapped potential there.

The MutantC features a QWERTY keyboard and sliding display, and seems more than a little inspired by early smartphone designs. You know, how they were before Apple came in and managed to convince every other manufacturer that there was no future for mobile devices with hardware keyboards. Unfortunately, hacking sessions will need to remain tethered as there’s currently no battery in the device. Though this is something [rahmanshaber] says he’s actively working on.

The custom PCB in the MutantC will work with either the Pi Zero or the full size variant, but [rahmanshaber] warns that the latest and greatest Pi 4 isn’t supported due to concerns about overheating. Beyond the Pi the parts list is pretty short, and mainly boils down to the 3D printed enclosure and the components required for the QWERTY board:  43 tactile switches and a SparkFun Pro Micro. Everything is open source, so you can have your own boards run off, print your case, and you’ll be well on the way to reliving those two-way pager glory days.

We’re excited to see where such a well documented open source project like MutantC goes from here. While the lack of an internal battery might be a show stopper for some applications, we think the overall form factor here is fantastic. Combined with the knowledge [Brian Benchoff] collected in his quest to perfect the small-scale keyboard, you’d have something very close to the mythical mobile Linux device that hackers have been dreaming of.

Alan Kay - A personal computer for children of all ages

The KiddiComp concept, envisioned by Alan Kay in 1968 while a PhD candidate,and later developed and described as the Dynabook in his 1972 proposal "A personal computer for children of all ages", outlines the requirements for a conceptual portable educational device that would offer similar functionality to that now supplied via a laptop computer or (in some of its other incarnations) a tablet or slate computerwith the exception of the requirement for any Dynabook device offering near eternal battery life. Adults could also use a Dynabook, but the target audience was children.

Part of the motivation and funding for the Dynabook project came from the need for portable military maintenance, repair, and operations documentation. Eliminating the need to move large amounts of difficult-to-access paper in a dynamic military theatre provided significant US Department of Defense funding.

Though the hardware required to create a Dynabook is here today, Alan Kay still thinks the Dynabook hasn't been invented yet, because key software and educational curricula are missing. :: Phase 0 :: Permutations

Prof. Dr. Daniel D. Hromada (ECDF Juniorprofessor for Digital Education) and Nikoloz Kapanadze (Kunst und Medien; Tutor)
We present multiple digital artefacts which emerged first stage of construction of a digital Primer. These include: touchscreen&HTML5-based prototype; e-ink screen (recently broken) with touchless sensing embedded in an upcycled old book; and OID-enriched paper page from the Primer "Wir Kinder vom Zirkus Palope". 
Aside this, we'll present some additional digital artefacts exploiting the modularity and extensibility of Raspberry Pi technology: Make Your Own Instrument kits, touchless PONG-game, speak2listen headphones and a touch-the-plant botanics education setup. 



You'll get the signature only when actively participating on creating of an artefact which DOES something, e.g.

  • digital primer

  • music instrument for algorithmic drum circle

  • garden guardian

  • digital primer

  • light source

Making of a digital education artefact #3 : E-ink

Make Your Own Device ! During this seminar, we are going to familiarize ourselves with e-ink technology: what are its main (dis)advantages in comparison to dominant display technologies. And we are going to connect our e-papers to Raspberry Pis and Arduinos and create some real stuff: e-paper based wearables (maybe), the second prototype of a digital primer and who knows, maybe a cool interactive but low-consumption menu for Medienhaus cafeteria.

M.O.D.E.A #4 : (Machine) learning and data (science)

In this course, we are going to follow some nice O'Reilly data science manual and, line by line, learn about meaning of terms like "feature", "multi-class classification", "training" and "cross validation" and, while doing so, acquire all necessary prerequisities of "the most sexy job of 22nd century".

We start this Friday (24th April) at 10:00 am

M.O.D.E.A #5 : Voice and Speech - Lost in Translation

In the middle of a battle there is a company of Italian soldiers in the trenches, and a commander who issues the command “Soldiers, attack!” He cries out in a loud and clear voice to make himself heard in the midst of the tumult, but nothing happens, nobody moves. So the commander gets angry and shouts louder: “Soldiers, attack!” Still nobody moves. And since in jokes things have to happen three times for something to stir, he yells even louder: “Soldiers, attack!” At which point there is a response, a tiny voice rising from the trenches, saying appreciatively “Che bella voce!” “What a beautiful voice!” - excerpt from the book 'A Voice and nothing more' by Mladen Dolar

In this course, we are going to make your own digital artefacts in the scope of your personal interests in Voice and Speech.
Throughout the seminar, we will build our own personal speech recognition system based on machine learning which can understand (more specifically „transcribe“) human speech as a medium for our artistic practice. For the first half of the seminar, students will be introduced a domain of Automatic Speech Recognition (ASR) technology, and also diverse ways how speech-to-text (STT) inferences can be realized on non-cloud, local (i.e. edge-computing) architectures. It means that python programming and basic unix command line skills will be involved.
By the time we will have developed our own system, we will dive into making artfacts (media installation, educational device, musical instrument, performative material, sound works, etc, of your choice) where human and machine will communicate in human voice and speech as the second half.

*Please register for the seminar before the semester starts by e-mail.
*Seminar starts on 27.10
*A Raspi 4B and a ReSpeaker 2-Mics Pi HAT will be given to each person during the semester period.
*The seminar takes place time to time at Berlin Open Lab (Einsteinufer 43)
