🚨“See through walls” without WiFi.
Iridium L-band: 1–6 dB through walls, 2–4 dB foliage.
Add micro-Doppler + multi-sat CIR → passive detection with just an SDR.
No TX. Satellites do the work. 🤯

Un moteur imprimé en 3D pour 0,5$. Une entreprise pourrait télécharger le plan, et réparer une élément défaillant de sa chaîne de prod en quelques heures. Ou nous, nos robots personnels…
Les Électrons Libres@lel_media

Imprimer en 3D un vrai moteur électrique en trois heures ! Une plateforme d’impression 3D capable de produire un moteur électrique fonctionnel en seulement trois heures, pour un demi dollar ? C’est ce que viennent de réaliser des ingénieurs du Massachusetts Institute of Technology (MIT). Traditionnellement, la fabrication d’un tel moteur exige de multiples étapes complexes – usinage de pièces métalliques, bobinage de fils, assemblage d’aimants – dans des usines spécialisées, souvent sur plusieurs jours ou semaines, avec une chaîne d’approvisionnement lourde et coûteuse. Grâce à leur nouvelle imprimante, les chercheurs ont déposé, couche par couche, cinq matériaux aux propriétés distinctes. Une fois l’impression terminée, il ne reste plus qu’une seule étape simple : aimanter les matériaux magnétiques. Le moteur ainsi créé fonctionne immédiatement et offre même une force d’actionnement plusieurs fois supérieure à celle de certains systèmes hydrauliques équivalents. Le coût en matériaux ? À peine cinquante centimes par unité. Et ce, en modifiant une imprimante commerciale pour traiter simultanément filaments, granulés et encres. Cette technologie ouvre la porte à l’impression sur place de pièces de rechange pour robots, drones, appareils médicaux ou systèmes spatiaux, sans dépendre de chaînes d’approvisionnement vulnérables dans un contexte géopolitique tendu. Elle réduit drastiquement les délais, les coûts et les déchets, tout en permettant des conceptions impossibles avec les méthodes classiques. À plus long terme, elle rapproche le rêve de fabriquer des objets électromécaniques entiers, voire des véhicules complets, directement par impression 3D.

Le PDG qui a créé Claude vient de publier une lettre de 38 pages pour toute l'humanité. Dario Amodei a cartographié exactement quelles carrières survivront à l'IA et lesquelles non. Rien d'exagéré. Rien d'apocalyptique. Juste la prédiction la plus froide et précise qu'ait faite un leader de l'IA. Mais la page 29 contient un cadre de raisonnement qui transforme l'IA de "ce qui te remplace" en "ton plus grand avantage injuste". Voici 9 prompts Claude basés sur la méthodologie d'Amodei qui te placent des années en avance : [ Ajoutez en signet 🔖pour ne pas perdre ! ]

🚀 Dünyanın ilk füzyon roketi ateşlendi: Yeni bir uzay çağı başlıyor! 📌 İngiltere merkezli Pulsar Fusion, Sunbird füzyon roketinde ilk plazmayı üreterek uzay itkisinde kritik bir eşiği aştı. 📌 Füzyon roketleri, derin uzay görevlerinin hızını kökten değiştirebilecek bir teknoloji olarak görülüyor. 📌 Sunbird, doğrudan yük veya astronot taşımayacak. Bunun yerine, alçak Dünya yörüngesinde (LEO) uzay araçlarına kenetlenerek onları hedeflerine taşıyan bir “uzay römorkörü” gibi çalışacak. 📌 Sistem olgunlaştığında 1.000 ila 2.000 kilogram yük taşıyan bir aracı Mars yörüngesine 6 aydan kısa sürede ulaştırabilecek. 📌 Günümüzde kullanılan kimyasal roket teknolojisiyle bir uzay aracının Mars’a ulaşması yaklaşık 10 ay sürebiliyor.

Today, @teamairbase is emerging from stealth. With a $5M round led by @a16z alongside @squadra_vc and @foundersysk, we’re solving a critical, invisible bottleneck in American national security: radio frequency (RF) spectrum coordination. Nearly all modern technology–from 5G on our smartphones to weather satellites and next-generation autonomous defense systems–depends on spectrum access. Yet, as demand for connectivity soars, the government systems used to allocate spectrum licenses and coordinate usage are stuck in a bygone era. Slow, manual workflows stall innovation and allow our adversaries to outpace us. Airbase is building the modern infrastructure for RF spectrum licensing, coordination, and intelligence. This isn’t merely a vision. We’ve secured an active contract with the U.S. Government to build and deploy the modern, software-defined data and coordination layer. We’re grateful to be partnering with brilliant minds across civil federal, commercial, and defense. America’s next era isn't waiting to be built. It’s waiting to be unleashed. The future of wireless is resilient, connected, and abundant. @espricewright, @rmcentush, Alex Oliver, Guy Filippelli, Dom Ventimiglia, Dan Madden, Jen Yip, and many more

OK SDR fans, here's something else to try. Finding amateur radio balloons through their low power WSPR beacons, also on 20 m, here at 14.0956 MHz. Here I am picking up the signal from balloon N4KCT, off the coast of California. This balloon is likely using 10 or 20 milliwatts of solar power. The first image shows the impressive reach of the balloon's signal. Second shows data on the capture by my system at callsign VE7AFV. Mapping is in the wonderful site WSPR.rocks. Antenna: MLA-30+ loop SDR: SDRplay RSPduo Tuner/decoder software: SDRuno, JTDX. Requires a virtual audio cable to link tuner and decoder.

🚨 BREAKING: Yann LeCun's team just dropped a world model that runs on a single GPU. It is called LeWorldModel. And to understand why it’s a massive deal, you have to understand the fatal flaw in every AI you use today. LLMs only predict the next word. They are incredibly good at language, but they have absolutely no understanding of reality. They can write a beautiful poem about a ball bouncing off a wall. But they cannot predict where the ball will actually land. World models predict physics. Objects moving, colliding, and falling. It is the foundational intelligence required for robots to plan and self-driving cars to navigate. But until today, world models kept collapsing. They would cheat the test by predicting the exact same output every time. LeCun's team just solved it. They built a 15-million parameter model that learns the laws of physics directly from raw pixels. It uses 200x fewer tokens than the alternatives. No massive supercomputers. No billion-dollar clusters. Just a single GPU and a few hours of training. We spent the last two years teaching AI how to talk. Now, we are teaching it how to see.
