The signature proves less than the project implies — that is what makes it interesting. tech Léa Perrin https://irz.fr/en/articles/kmart-digicam-projector-lens-en https://irz.fr/en/articles/kmart-digicam-projector-lens-en Sat, 05 Sep 2026 02:30:00 GMT A 'C-mount lens' bought for $20 on eBay turned out to be a Super 8 projector lens. Mason Mirabito redesigned his 3D-printed adapter around it, and learned why a camera's geometry has to be discovered with a file. craft Léa Perrin https://irz.fr/en/articles/eta-learning-precipitation-en https://irz.fr/en/articles/eta-learning-precipitation-en Fri, 04 Sep 2026 10:15:00 GMT A new MIT algorithm generates plausible extreme-event scenarios without ever training on an extreme event. The trick, and its limits, live in what is imposed on the model. ai Hugo Marchal https://irz.fr/en/articles/flit-m2i-bonded-frame-en https://irz.fr/en/articles/flit-m2i-bonded-frame-en Fri, 04 Sep 2026 09:30:00 GMT The FLIT M2i swaps the welds on its aluminium frame for structural adhesive. Welding weakens thin tubes; bonding buys back alignment and weight, but raises repair questions that are not new. craft Camille Morel https://irz.fr/en/articles/verre-remplace-pas-encore-organique-en https://irz.fr/en/articles/verre-remplace-pas-encore-organique-en Fri, 04 Sep 2026 08:30:00 GMT Glass-core substrates were meant to replace organic packaging after Intel's 2023 announcement. Three years on, they are only entering package qualification, and the first product keeps slipping. tech Camille Morel https://irz.fr/en/articles/kallax-workbench-ikea-en https://irz.fr/en/articles/kallax-workbench-ikea-en Fri, 04 Sep 2026 02:20:00 GMT Michael Green built a €130 workbench from a KALLAX unit and an old desk top, against €1,000 for custom furniture. The point is not the price, but a standard module becoming a reversible fabrication platform. craft Hugo Marchal https://irz.fr/en/articles/laser-graffiti-projection-wall-en https://irz.fr/en/articles/laser-graffiti-projection-wall-en Thu, 03 Sep 2026 09:00:00 GMT Laser Graffiti runs in the browser and paints on a wall from a laser pointer. Behind the gimmick: calibration across camera, projector and surface, plus a neat feedback problem. tech Léa Perrin https://irz.fr/en/articles/vibe-coded-mnist-chip-tapeout-en https://irz.fr/en/articles/vibe-coded-mnist-chip-tapeout-en Thu, 03 Sep 2026 08:45:00 GMT Ken Chang admits he cannot write Verilog, yet an AI co-wrote a handwritten-digit classifier that is heading for a TinyTapeout shuttle. Everything checks out in simulation; the foundry remains the real test. tech Léa Perrin https://irz.fr/en/articles/lethal-universal-travel-adapter-en https://irz.fr/en/articles/lethal-universal-travel-adapter-en Thu, 03 Sep 2026 08:00:00 GMT A nine-dollar universal travel adapter bus-bars every set of prongs onto one conductor. Plug in one set and the others sit at mains voltage. tech Léa Perrin https://irz.fr/en/articles/phion-identite-fonte-partition-variable-en https://irz.fr/en/articles/phion-identite-fonte-partition-variable-en Wed, 02 Sep 2026 11:00:00 GMT Orkest Phion is a travelling orchestra with no permanent hall. Thonik anchored its identity in the variable font GT Planar, whose slant angle acts as a score for every campaign. creative Manon Girard https://irz.fr/en/articles/ziva-tissues-before-the-monster-en https://irz.fr/en/articles/ziva-tissues-before-the-monster-en Wed, 02 Sep 2026 09:00:00 GMT Ziva VFX builds the muscles, fat, fascia and skin of a digital character, then lets a solver compute how the matter deforms. VFX work moves before the drawing: you build an anatomy instead of sculpting a surface. tech Arthur Lacoste https://irz.fr/en/articles/badminton-robot-denso-arm-en https://irz.fr/en/articles/badminton-robot-denso-arm-en Tue, 01 Sep 2026 18:00:00 GMT Travis Mitchell turned a used Denso industrial arm into a badminton shuttlecock feeder. The robot behaved. Two small launch wheels nearly sank the whole project. craft Hugo Marchal https://irz.fr/en/articles/ibteda-urdu-archive-labels-en https://irz.fr/en/articles/ibteda-urdu-archive-labels-en Tue, 01 Sep 2026 15:30:00 GMT A community archive spent ten years fixing photographs of Urdu books by hand in Photoshop. When it had to stop, 526,000 scans remained. It recycled its own corrections to train the pipeline that replaced them. craft Camille Morel https://irz.fr/en/articles/cabin-sande-viking-roots-en https://irz.fr/en/articles/cabin-sande-viking-roots-en Tue, 01 Sep 2026 10:00:00 GMT At Randaberg, an 112 m² cabin rests on eighteen whole spruce trees kept with their roots: the root-starts form a timber knee, as in Viking hulls, made precise by 3D scanning and robotic milling. craft Arthur Lacoste https://irz.fr/en/articles/word97-debugger-cpu-erratum-en https://irz.fr/en/articles/word97-debugger-cpu-erratum-en Mon, 31 Aug 2026 12:50:00 GMT Near the end of Word 97 development, a reproducible crash vanished under a debugger. Microsoft traced it to a CPU erratum and patched one binary sequence with a NOP instead of changing compilers. tech Léa Perrin https://irz.fr/en/articles/mubites-pet-carbon-yeast-en https://irz.fr/en/articles/mubites-pet-carbon-yeast-en Mon, 31 Aug 2026 11:20:00 GMT µBites does not make plastic edible. PET is first broken into microbe-accessible molecules, then yeast rebuilds that carbon before the food mixture is printed into a cookie shape. tech Léa Perrin https://irz.fr/en/articles/stock-accurate-stockout-invumi-en https://irz.fr/en/articles/stock-accurate-stockout-invumi-en Mon, 31 Aug 2026 09:55:00 GMT A stock count can be perfectly accurate and still arrive too late. Invumi starts from real movements to help small teams work out what to reorder, and when. ideas Manon Girard https://irz.fr/en/articles/berkeley-humanoid-actuators-81-percent-en https://irz.fr/en/articles/berkeley-humanoid-actuators-81-percent-en Mon, 31 Aug 2026 09:01:00 GMT Berkeley Humanoid Lite costs $4,312 in its US BOM. Its 22 actuators account for $3,512. Openness does not erase their cost; it breaks the most expensive part into components that can be understood and replaced. tech Léa Perrin https://irz.fr/en/articles/autogeoref-sanborn-refuse-uncertainty-en https://irz.fr/en/articles/autogeoref-sanborn-refuse-uncertainty-en Mon, 31 Aug 2026 09:00:00 GMT AutoGeoRef automates the first placement of Sanborn maps without confusing an estimate with truth. Its most useful mechanism may be its ability to refuse a sheet. tech Léa Perrin https://irz.fr/en/articles/yxstaby-thumbstick-stool-en https://irz.fr/en/articles/yxstaby-thumbstick-stool-en Sat, 29 Aug 2026 09:30:00 GMT IKEA and Xbox built a stool from the controller stick's original 3D files. It tilts in every direction, but nothing brings it back to center: that job is yours. craft Hugo Marchal https://irz.fr/en/articles/synchronal-bimodal-nuclear-rocket-2026-en https://irz.fr/en/articles/synchronal-bimodal-nuclear-rocket-2026-en Sat, 29 Aug 2026 09:00:00 GMT Two engineers (NASA, General Atomics) describe the S-BNR: one reactor, two loops, two fuel zones, to bring the Mars transit under 335 days. Architecture, numbers and what is still missing. tech Arthur Lacoste https://irz.fr/en/articles/perry-neighborhood-unit-15-minute-city-en https://irz.fr/en/articles/perry-neighborhood-unit-15-minute-city-en Fri, 28 Aug 2026 11:30:00 GMT In 1929, Clarence Perry codified the neighborhood unit: school at the center, shops at the edge, a hard boundary. In 2016, the 15-minute city repaired it by switching the metric from space to time. ideas Arthur Lacoste https://irz.fr/en/articles/wildlife-tower-honeygar-multi-especes-en https://irz.fr/en/articles/wildlife-tower-honeygar-multi-especes-en Fri, 28 Aug 2026 11:20:00 GMT A five-metre-plus tower stacks reclaimed materials to house bats, owls and insects. The twist: its timber skin is designed to rot, while a hidden steel frame keeps the structure upright. craft Camille Morel https://irz.fr/en/articles/holly-thomas-journal-fragments-comic-en https://irz.fr/en/articles/holly-thomas-journal-fragments-comic-en Fri, 28 Aug 2026 11:10:00 GMT Picking up a Toad began with a diary written in the Andes, but Holly Thomas did not illustrate it entry by entry. She extracted sentences, placed them inside images and let conflicting feelings remain adjacent. creative Hugo Marchal https://irz.fr/en/articles/kizhi-lens-timber-viewfinder-en https://irz.fr/en/articles/kizhi-lens-timber-viewfinder-en Fri, 28 Aug 2026 11:05:00 GMT Kizhi Island is not getting another sculpture. A slatted timber frame points the visitor at the Pogost from the north, turning a touristic stop into a built way of looking. craft Léa Perrin https://irz.fr/en/articles/sourcehut-ai-authorship-boundary-en https://irz.fr/en/articles/sourcehut-ai-authorship-boundary-en Fri, 28 Aug 2026 10:56:00 GMT SourceHut's announced rule is more specific than a blanket LLM ban: private advice remains allowed, original AI-assisted content does not, and enforcement will use trust rather than detectors. ai Manon Girard https://irz.fr/en/articles/browser-loads-module-not-package-en https://irz.fr/en/articles/browser-loads-module-not-package-en Fri, 28 Aug 2026 10:42:00 GMT ES modules and import maps let browsers use libraries without a local bundler. Package resolution, CommonJS conversion, transformations and graph optimization still have to happen somewhere. tech Hugo Marchal https://irz.fr/en/articles/mark-francis-sound-as-grammar-en https://irz.fr/en/articles/mark-francis-sound-as-grammar-en Fri, 28 Aug 2026 10:28:00 GMT Chroma talks about frequency, echo and resonance. But the sources document no audio-to-colour converter: Mark Francis uses sound more like a grammar for rhythm, repetition, interruption and chance. creative Manon Girard https://irz.fr/en/articles/qctrl-no-gps-still-needs-gravity-map-en https://irz.fr/en/articles/qctrl-no-gps-still-needs-gravity-map-en Fri, 28 Aug 2026 10:14:00 GMT Q-CTRL corrected inertial drift over an 83 km maritime run with GNSS excluded from the navigation chain. The quantum sensor does not output position: it measures gravity and matches it against a map prepared beforehand. tech Hugo Marchal https://irz.fr/en/articles/dtile-3d-tile-system-en https://irz.fr/en/articles/dtile-3d-tile-system-en Fri, 28 Aug 2026 10:00:00 GMT Three Dutch industrial designers built a tile system that follows curves, corners, and volumes. No one could manufacture it, so they bought a factory. craft Camille Morel https://irz.fr/en/articles/andrew-ng-data-centric-two-curves-en https://irz.fr/en/articles/andrew-ng-data-centric-two-curves-en Fri, 28 Aug 2026 09:45:00 GMT Andrew Ng was arguing for data-centric AI in 2022. Four years later, small models have become dramatically more capable even as frontier compute keeps expanding. ai Camille Morel https://irz.fr/en/articles/rust-money-cannot-create-maintainer-en https://irz.fr/en/articles/rust-money-cannot-create-maintainer-en Fri, 28 Aug 2026 09:43:00 GMT Rust's first Maintainers in Residence program funds six contributors. Its most useful lesson is elsewhere: money can reserve time, but it cannot instantly buy the trust and context maintenance requires. tech Léa Perrin https://irz.fr/en/articles/berninox-disposable-part-smaller-en https://irz.fr/en/articles/berninox-disposable-part-smaller-en Fri, 28 Aug 2026 09:34:00 GMT The Berninox 316 separates two lifetimes: a 316L stainless-steel handle that stays, and a small multi-material head that wears out. Less dramatic than zero waste, but more useful. craft Camille Morel https://irz.fr/en/articles/hippie-houses-construction-never-ended-en https://irz.fr/en/articles/hippie-houses-construction-never-ended-en Fri, 28 Aug 2026 09:15:00 GMT Handmade Utopia returns to Northern California’s self-built homes half a century later. What endures is less a style than an ability to repair, extend and adapt. ideas Léa Perrin https://irz.fr/en/articles/sala-kin-khao-fixed-flood-threshold-en https://irz.fr/en/articles/sala-kin-khao-fixed-flood-threshold-en Fri, 28 Aug 2026 09:14:00 GMT Sala Kin Khao is not amphibious: its floor stays fixed 70 cm above the ground. Its real strategy combines a threshold, a 3 m grid, dry construction and parts that are easier to inspect and repair. craft Léa Perrin https://irz.fr/en/articles/sip-puff-forty-dollar-electronics-en https://irz.fr/en/articles/sip-puff-forty-dollar-electronics-en Fri, 28 Aug 2026 09:13:00 GMT Caleb Kraft's prototype brings sip-and-puff electronics down to about $40. Its code shows a capable gamepad architecture, but a testable assistive device costs more than its BOM. craft Manon Girard https://irz.fr/en/articles/ai-interface-museum-supervision-en https://irz.fr/en/articles/ai-interface-museum-supervision-en Fri, 28 Aug 2026 09:12:00 GMT The AI Interface Museum lines up 49 interfaces from 2011 to 2026. Their evolution says less about model capability than about the human role: command, prompt, converse, edit, then supervise. ai Hugo Marchal https://irz.fr/en/articles/saekdong-house-redistribute-before-adding-en https://irz.fr/en/articles/saekdong-house-redistribute-before-adding-en Fri, 28 Aug 2026 09:11:00 GMT In Seoul, Saekdong House removes the old living room to restore a courtyard, moves floor area into an annex and keeps the air-raid shelter. Renovation begins by redistributing what exists. craft Hugo Marchal https://irz.fr/en/articles/neramit-six-meter-nonarchitecture-en https://irz.fr/en/articles/neramit-six-meter-nonarchitecture-en Fri, 28 Aug 2026 09:10:00 GMT Boonserm Premthada calls Neramit non-architecture. The useful move is more concrete: start from six-metre stock tubes, reduce offcuts and make one roof perform several jobs at once. craft Hugo Marchal https://irz.fr/en/articles/corrosion-simulation-between-tests-en https://irz.fr/en/articles/corrosion-simulation-between-tests-en Fri, 28 Aug 2026 09:09:00 GMT At DTU, a model links water films, geometry and PCB leakage current. Its useful role is not replacing climate tests but exploring parameters between experiments. tech Hugo Marchal https://irz.fr/en/articles/warehouse-project-night-archive-en https://irz.fr/en/articles/warehouse-project-night-archive-en Fri, 28 Aug 2026 09:08:00 GMT Three Warehouse Project photographers show why a durable archive cannot be built from headliners alone: arrivals, pauses, gestures, crowds and the end of the night carry the culture forward. creative Hugo Marchal https://irz.fr/en/articles/ai-contribution-credit-maintainer-en https://irz.fr/en/articles/ai-contribution-credit-maintainer-en Fri, 28 Aug 2026 09:07:00 GMT A pull request can take minutes to generate and still demand real review work. Projects are therefore filtering less for whether code exists and more for evidence that a human actually owns it. ai Hugo Marchal https://irz.fr/en/articles/duckdb-aws-governance-test-en https://irz.fr/en/articles/duckdb-aws-governance-test-en Fri, 28 Aug 2026 09:06:00 GMT DuckLabs is set to join AWS in September, while the Foundation retains DuckDB's IP and trademarks. Independence will be easier to judge through roadmap and extension control. tech Manon Girard https://irz.fr/en/articles/let-me-click-state-repair-en https://irz.fr/en/articles/let-me-click-state-repair-en Fri, 28 Aug 2026 09:05:00 GMT Ilya Birman's 'Let me click' principle accepts intent before repairing dependencies. A reliable target must look actionable, be reachable and produce a coherent state. tech Manon Girard https://irz.fr/en/articles/lassie-social-skin-en https://irz.fr/en/articles/lassie-social-skin-en Fri, 28 Aug 2026 09:04:00 GMT The Lassie concept wraps a quadruped in a removable knitted suit while keeping impact zones hard. Softness becomes a replaceable layer rather than the structure. craft Hugo Marchal https://irz.fr/en/articles/plou-prou-maintaining-the-image-en https://irz.fr/en/articles/plou-prou-maintaining-the-image-en Fri, 28 Aug 2026 09:03:00 GMT Plou prou? materializes more than 12,000 litres of evaporation over fourteen days. What it exposes is the daily cost of maintaining an architectural image. ideas Hugo Marchal https://irz.fr/en/articles/scanwheel-pixels-cost-different-en https://irz.fr/en/articles/scanwheel-pixels-cost-different-en Fri, 28 Aug 2026 09:02:00 GMT Scanwheel displays 4,096 × 20 pixels with a printed drum and five LEDs. Width mostly costs memory; height means rebuilding the mechanics. tech Léa Perrin https://irz.fr/en/articles/antidote-ski-lift-engine-en https://irz.fr/en/articles/antidote-ski-lift-engine-en Fri, 28 Aug 2026 09:01:00 GMT Antidote carries no motor: the lift supplies altitude and gravity supplies the descent. The real product is a loop built around existing ski infrastructure. craft Léa Perrin https://irz.fr/en/articles/notion-office-visible-seams-en https://irz.fr/en/articles/notion-office-visible-seams-en Fri, 28 Aug 2026 09:00:00 GMT At Notion's headquarters, IA does not disguise the mismatch between a 1907 building and a new office plan. The visible patch becomes a design method. craft Camille Morel https://irz.fr/en/articles/phillips-print-identity-proofing-en https://irz.fr/en/articles/phillips-print-identity-proofing-en Wed, 26 Aug 2026 15:10:00 GMT Laura Clink did not hand Phillips Print one locked logo.
