Ağırlık disklerini revolver silindiri gibi döndüren ve mermi şeklinde yüklenen "Revolver Dumbbell" adlı yeni bir spor aletini tanıtıldı.

Four rotors create complete control authority. Eight offers redundancy. But can someone explain why in the world you'd want to add weight and complexity to pivot each rotor pair?

🔴Çin ordusu,optik güdümlü İHA’lara karşı aerosol duman perdesi sistemi kullanmaya başladı. Sistem,yoğun duman tabakası oluşturarak İHA’ların hedefi görmesini ve optik takip yapmasını engelliyor.

A Chinese drone show company just demonstrated how they fly 20 drones indoors in a tight space. The flight programming behind this is next-level.

@rafamilton44 @WCTRCollector sert kapaklı albüm aramıyorsanız fazladan albümüm var

@WCTRCollector Ya benim merak ettiğim bu sevkiyat ne kadar daha sürecek? 1 aydir arıyoruz daha sadece bir kaç paket alabildim album bile yok

Biraz da stok bilgisinden ziyade sohbet edelim. Bu stok sorunu sadece bu turnuvada mı oldu? Yoksa daha önce başka turnuvalarda da böyle stok sorunu yaşanmış mıydı?

study topology optimization. it’s one of the most beautiful ideas in engineering. instead of asking: “how do i design this part?” you ask: “where should material exist?” that shift is powerful. what it teaches you: • constraints first → load, weight, stiffness, space, material, manufacturing limits • remove dead material → if it doesn’t carry force, it doesn’t belong there • let physics shape the design → the structure emerges from stress paths, not aesthetics • optimize for function → lighter, stronger, more efficient parts • think like nature → bones, trees, wings. material appears where forces demand it why it matters: topology optimization is how engineering starts looking biological. • parts stop being blocky. • structures become organic. • material becomes intentional. you see it in aerospace, automotive, robotics, medical implants, and advanced manufacturing. especially with 3d printing, this becomes serious. because now we can actually manufacture geometries that were impossible before. topology optimization is not just design software. it’s a new way of thinking: don’t add material until it works. remove everything until only the load path remains.

🚨🇷🇺 ZELENSKY IN PANIC: RUSSIA DEPLOYS NEW GAME-CHANGING DRONE INTERCEPTOR Russian units are fielding the Sokol-I — a hand-launched pusher-prop interceptor already shredding the Leleka-100 and Hornet UAVs that feed Kiev’s reconnaissance and fire correction. 🔸 Russian Sokol-I crews are destroying 3–5 Ukrainian UAVs per day, directly degrading enemy aerial spotting and artillery adjustment in contested zones. 🔸 The Sokol-I’s high-mounted wing and pusher design delivers 135–140 km/h cruise speed, enabling effective interception of 120–130 km/h targets from 50 m to 2,800 m altitude. 🔸 Hand-thrown launch combined with mobile radar or optoelectronic cueing allows instant forward deployment with zero runway or heavy logistics. 🔸 The interceptor eliminates drones via kinetic impact with warhead detonation or 1.5–3 m proximity fuse, while maintaining high maneuverability against evasive low-altitude targets. 🔸 Future multi-channel integration will let single Sokol-I crews engage multiple targets simultaneously, dramatically raising the cost of Western-backed Ukrainian drone operations. Do you think NATO can match Russia's innovation in drones?

ÇELİK KUBBE'nin lazer gücü ALKA'nın yetenekleri artıyor • Türk savunma sanayisi tarafından güvenlik güçlerine kazandırılan ve "lazer silahı" olarak da bilinen ALKA Yönlendirilmiş Enerji Silah Sistemi, yeni yeteneklerle gelişimini sürdürüyor • ROKETSAN Silah Sistemleri ve Entegrasyon Direktörü Koray Dayanç: • Algılama ve tespit zamanlarını kısma, iyileştirmeler konusunda radarımızda güncellemeler yaptık. Daha fazla hedefi tespit edebilmek adına da yeni radar teknolojilerine geçmek üzerine çalışmalar yapıyoruz • Yapay zeka algoritmalarını komuta kontrol sisteminin içine gömdük. Hem algılama süresini hem önceliklendirmeyi hem de operatöre düşen zamanlamayı kısacak şekilde tedbirlerimizi aldık • (Lazer gücü) Belki 5, 10, 20 katlar şeklinde ilerlememiz gerekiyor. Çünkü tehditler çok hızlı ve asimetrik şekilde gelişiyor. Dolayısıyla güç çarpanını da hızlı bir şekilde artıracağız #SavunmaSanayi @roketsan #ÇelikKubbe #ALKA aa.com.tr/tr/bilim-tekno…

A new Russian concept for an FPV fiber-optic coil disc is called “Tort”. It has an internal winding held together with an adhesive compound and pre-twisting so that the cable emerges straight. The Russians claim that this results in 70% less cable breakage during flight.

@TurkalpU @eskibirkeko hangi mağazalar stok var?

@eskibirkeko Hocam beylikduzu'ndeyim paketleri alinca takas listesini paylasirim takip ettim

Panini kartları stoklara gelmeye başlamış. Bu bolluk sonrası takas işine başlamak lazım. Beylikdüzü/Büyükçekmece taraflarında olan arkadaşlar menşın atabilir.

Şöyle gösterimler bize de lazım

【設計とは】「設計は何をやってるの」という質問受ける事がある。定型の分野では、ただの穴埋め問題だったりもするが、柔軟なな条件下で要求を満たす解答を出す上位（概念）設計は普通、一般の人には理解ができない。学習で得る感覚ではなく、持って生まれる物だ。 写真は脚設計の例だが…続

🚨🇷🇺Russia can produce up to 15,000 FPV drones per day Russian special military operation in Ukraine has finally cemented the status of unmanned aerial vehicles as a key element of modern warfare, Russian First Deputy Prime Minister Denis Manturov said.

🇷🇺 Russia has unveiled its new “Argus” UAV at SPIEF It can reach altitudes of up to 25 km and remain flying for up to 40 days using only solar power

Yazıcıdan çıkması ile uçması arası yarım saat. Bataryasız 50 gram, batarya ile 92 gram Bu Li-ion pilli dronlara Long Range deniyor çünkü li-ion pillerin enerji yoğunluğu li-po pillerden çok daha yüksek. Zorlamadan daha uzun süre havada kalabiliyorlar.

CAD used to take years to learn. Now it takes one sentence. “If you can type, you can build.” We’re letting anyone get started for $2. cadxstudio.in

Китайці вже штампують «цивільні» дрони-перехоплювачі, які продаються в інтернеті у роздріб. Сам перехоплювач не оснащений бойовою частиною та знищує ціль за рахунок власної кінетичної енергії, фактично тараном у повітрі.

🚨🇨🇳 PENTAGON'S WORST NIGHTMARE: CHINA'S UNJAMMABLE AI DRONE SWARMS China just dropped HG-STR — the AI algorithm letting drone swarms autonomously detect, coordinate and annihilate targets even when jammed into total comms blackout and near-zero visibility. 🔸 HETEROGENEOUS GRAPH BRAIN: Tags every object by class (friendly UAV, search zone, enemy target) — unlike the West’s outdated “everything is data” swarms. 🔸 6.6 MILLISECONDS DECISIONS: Memory module stores last-known positions so swarms keep fighting autonomously when links die. 🔸 PREDICTIVE HUNTING: Estimates hidden enemy locations from terrain, patterns and prior intel — no ground control needed. 🔸 DOMINANT SIM RESULTS: 100% target hit probability in testing, showcasing China's edge in next-gen swarm intelligence Do you think U.S. can catch up China in drone AI technology?
