## Latest articles

- [At EPFL, a hollow cavity becomes an acoustic thruster](https://irz.fr/en/articles/acoustic-resonator-thrusters-en.md): At EPFL, tuned cavities convert external sound into an air jet. The motor is not simply miniaturized: part of the machine is moved into its environment.
- [Sigma removes almost all the controls, then machines the body for seven hours](https://irz.fr/en/articles/sigma-bf-seven-hours-en.md): The Sigma BF tries to make the camera disappear between photographer and image. Achieving that visible simplicity moves a surprising amount of complexity into the factory.
- [A 2.9MB song becomes eight QR codes and a paper cassette](https://irz.fr/en/articles/paper-tunes-music-on-paper-en.md): Paper Tunes does not really put an MP3 into a QR code. It first compresses music into a neural representation, then turns that data into a physical cartridge and an offline radio payload.
- [Can paint really be open source?](https://irz.fr/en/articles/experimental-paint-archive-open-materials-en.md): The Experimental Paint Archive publishes 28 paints, gels and conductive materials. Its most interesting question goes beyond the recipes: what has to be documented before a material is genuinely reproducible?
- [No supplier would tool up for this C‑17 part. So the factory became the inventory](https://irz.fr/en/articles/c17-incremental-sheet-forming-en.md): A nose panel no supplier wanted to tool up for could have grounded a C‑17 for years. The Air Force formed one without a dedicated die, pointing to a different model for keeping old machines alive.
- [Bill Gates, the science of power](https://irz.fr/en/articles/bill-gates-power-microsoft-philanthropy-en.md): From Microsoft meeting rooms to global health, employee testimony, antitrust archives and academic research show how Bill Gates turns strategic positions into power over entire systems.
- [Two families, one volume, a game of Tetris: how a constraint became a plan](https://irz.fr/en/articles/woonpioniers-cohouse-tetris-en.md): The Dutch municipality would only allow one building volume for two families. Woonpioniers answered by interlocking the two homes around each other “like a game of Tetris”, and the constraint became the plan.
- [What if your judgment could outlive you? The hard part is the tacit](https://irz.fr/en/articles/bottle-judgment-outlive-you-en.md): An essay argues that AI finally makes it possible to extract a person’s judgment from their head — to “productize a person”. The interesting question is what survives the extraction, and what only travels hand to hand.
- [Vocal Slice turns a transcript into the timeline: edit audio by selecting text](https://irz.fr/en/articles/vocal-slice-text-audio-edit-en.md): Vocal Slice transcribes a voice recording on your machine, then lets you cut the audio by selecting text in the transcript. The waveform stops being the timeline; the words become it.
- [The Godox C100 removes the screen and asks you to trust a viewfinder](https://irz.fr/en/articles/godox-c100-no-screen-camera-en.md): Godox’s first camera has no rear screen and no electronic viewfinder — just a transparent optical viewfinder, a light meter, and a price around thirty dollars.
- [A website can describe you before you click: the quiet machinery of fingerprinting](https://irz.fr/en/articles/fingerprinting-cookie-before-click-en.md): A single page can build a detailed profile of your browser before you click anything — no cookie, no permission, no consent dialog. The banner is the visible part; fingerprinting is the part that survived it.
- [C3 is stepping away from the ‘C alternative’ label](https://irz.fr/en/articles/c3-general-purpose-positioning-en.md): Christoffer Lernö thought “C alternative” meant a modernised C for building applications. He now believes the phrase mostly evokes C’s systems niches, and is changing how C3 describes itself.
- [In Ichihara, a six-tatami room keeps the building’s old layers instead of erasing them](https://irz.fr/en/articles/ichihara-six-tatami-tea-room-en.md): Kurosawa Kawara-ten renovates a small family annex without editing its history down to one period. Salvaged oak, reused keyaki, new cypress, Corten steel and titanium are allowed to age differently.
- [A Nokia DCT3 emulator boots real firmware without patching it](https://irz.fr/en/articles/nokia-dct3-emulator-en.md): The DCT3 project models the chips, display, SIM and even a synthetic GSM network. Nokia firmware is neither bundled nor patched: users bring their own .fls image.
- [Two lasers strengthen the bonds between FDM layers](https://irz.fr/en/articles/laser-fdm-layer-bonding-en.md): An experimental toolhead reheats the previous layer just before the nozzle arrives. In the creator’s tests, ABS reached up to 94% of the strength measured in the other orientation.
- [The Famicom modem survived. Its network had to be rebuilt around it](https://irz.fr/en/articles/famicom-network-reconstruction-en.md): The 1988 hardware still works. Giving it something to talk to required a new flash card, two CPUs worth of reverse engineering, a simulated phone line and a replacement for a vanished server.
- [Qwen, Grok, GLM and DeepSeek: the model is no longer the whole product](https://irz.fr/en/articles/ai-models-harnesses-august-2026-en.md): In fifteen days, Qwen 3.8, DeepSeek V4 Pro, Muse Code, Grok 4.6, Gemini 3.7 Flash and several open models arrived. The more interesting change sits around them: the harness is becoming a measurable part of the product.
- [Low-tech Lab applied low-tech thinking to its own server](https://irz.fr/en/articles/lowtech-self-hosting-server-en.md): Three months of experimentation, a migration away from Google and CC BY-SA documentation: Low-tech Lab treats self-hosting as a skill to transmit.
- [Instagram tried dropping its script wordmark. It stopped looking like Instagram](https://irz.fr/en/articles/instagram-refresh-script-en.md): Instagram’s 2026 refresh is mostly a lesson in constraint: after hundreds of directions, the team discovers what an omnipresent brand can no longer remove.
- [This printer already had the sensor needed to calibrate its extrusion](https://irz.fr/en/articles/prusa-load-cell-pressure-advance-en.md): PrusaPATuner repurposes the Nextruder load cell to measure extrusion response and estimate Pressure Advance without adding another sensor.
- [PyPI can prove where a package came from. Not yet that it matches the source code](https://irz.fr/en/articles/pypi-reproducible-builds-en.md): A study of 12,180 PyPI releases shows why provenance, byte-for-byte identity and build equivalence answer three different trust questions.
- [At EPFL, digital carpentry keeps the saw in the carpenter’s hands](https://irz.fr/en/articles/augmented-carpentry-hand-tools-en.md): Augmented Carpentry adds vision, tracking and feedback to ordinary handheld power tools. A one-to-one fabrication campaign shows what this compromise gains, and where it breaks.
- [STL forgot almost everything about a 3D model. That is why it survived](https://irz.fr/en/articles/stl-nearly-40-3mf-en.md): STL does not know the unit, color or material of your part. It turns curves into triangles and forgets almost everything about the original model. That loss is also part of why it became so hard to replace.
- [Human Computers: the machine never worked alone](https://irz.fr/en/articles/human-computers-labour-en.md): RYBN’s project connects human computers, Mechanical Turk and data annotation. Behind the metaphor is a practical question: where does the work that makes a system computable hide?
- [Before the cloud, data had weight: what old processing chains reveal](https://irz.fr/en/articles/old-data-processing-en.md): Carved bones, clay tablets, punched cards and human operators tell a less abstract story of data: matter that must be prepared, moved and checked.
- [How Buildings Learn: the real building begins after handover](https://irz.fr/en/articles/how-buildings-learn-en.md): Stewart Brand’s book and BBC series shift attention to life after handover: building layers age at different speeds, and that friction can become design material.
- [On embedded Linux, logs are memory you have to design before failure](https://irz.fr/en/articles/embedded-linux-logging-en.md): A deployed device cannot record everything. Its logging system must decide in advance which evidence will survive the next incident.
- [DS8: a PS Vita becomes an instrument because its controls resist](https://irz.fr/en/articles/psvita-ds8-groovebox-en.md): DS8 Drumstream does not revive the PS Vita through nostalgia. It turns its buttons, sticks and limits into an instrument grammar.
- [TR-808: three ways to keep a machine that no longer changes alive](https://irz.fr/en/articles/tr-808-firmware-mods-en.md): Around the TR-808, repair, extension and reconstruction are not three kinds of nostalgia. They are three ways of deciding what an instrument should remain capable of being.
- [EITWatch: the interface begins in tissue, before the screen](https://irz.fr/en/articles/eitwatch-gesture-watch-en.md): EITWatch places eight electrodes under a watch to read gestures from changes in wrist impedance. Its value is less the 92% headline than the tradeoff between geometry, calibration and everyday use.
- [Poem/1: the real product begins after the first clock ships](https://irz.fr/en/articles/poem-1-firmware-en.md): A Poem/1 update reveals the quiet work after a small connected object ships: fixing, recovering, distributing and documenting.

- [Haworth sends Fern chair scrap back into the next chair](https://irz.fr/en/articles/haworth-fern-closed-loop-en.md): With PADNOS and Royal Technologies, Haworth turns black Fern plastics into pellets and new parts, while factory scrap also travels back into the same loop.
- [MIKU turns the 3D printer bed limit into a construction rule](https://irz.fr/en/articles/miku-modular-print-en.md): A full-size bag will not fit on many accessible printers. MIKU answers with one flexible brick that repeats, connects without glue and can be replaced individually.
- [To film a potato peeling itself, he had to build a steam machine](https://irz.fr/en/articles/steam-decompression-peeler-en.md): Stuff Made Here wanted to see industrial steam peeling happen. The hard part was not the potato, but building an observable prototype without turning the workshop into a projectile.
- [WifiSense-Pi turns the room’s Wi-Fi into a breathing sensor](https://irz.fr/en/articles/wifisense-pi-presence-en.md): An ESP32-S3 and Raspberry Pi read changes in the Wi-Fi channel to distinguish motion, presence and breathing, while documenting what the system cannot infer.
