  2. (archaeology) An object, such as a toolweapon or ornament, of archaeological or historical interest, especially such an object found at an archaeological excavation. 

    The dig produced many Roman artifacts.

  3. Something viewed as a product of human conception or agency rather than an inherent element. 

  4. structure or finding in an experiment or investigation that is not a true feature of the object under observation, but is a result of external action, the test arrangement, or an experimental error.

    The spot on his lung turned out to be an artifact of the X-ray process.


  5. (biology) A structure or appearance in protoplasm due to death, method of preparation of specimens, or the use of reagents, and not present during life.

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.

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.

sonic
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.

Touchless Ukulele
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. 
Carboard Primer
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.

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.
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.

mutantC

https://mutantc.gitlab.io/index.html

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.
