seestar S50 pro camera sensor

 from Luca, aka spaceKoala, close up of S50 pro sensor for S50 pro. TLDR: NOT a IMX585. ZWO facebook post  on 27 Aug cloudynights reddit: software compatible S50 pro main sensors: IMX06a IMX585 SmartSens SC880SL (8MP)  spec  in 2023 OmniVision OS08B10   spec  in 2021. details here from cloudynights post   Seestar Pro's not sourcing their "585" sensors from Sony? milleniumfalcon here  in Cloudynights reddit The S50 Pro has been released, but the specs on the ZWO website do not state "585" sensor. They only give general specs that match the 585. The S30 Pro page on ZWO doesn't either. Did it ever? Retailers state "585", but maybe this is no longer correct. (Update: It isn't stated on their global site, but the US store site states 585) Sam (ZWO CEO) did mention to Luca at NEAF, "Sony, they say they cannot provide enough sensor" Context starts HERE in her video. The quote starts at 23:21.  Cuiv, in his review, points out HERE that ...

BEST (Burning Plasma Experimental Superconducting Tokamak)

  The toroidal superconducting magnet: The newly accepted toroidal field superconducting magnet, a D-shaped structure measuring 21 meters long, 12 meters wide and weighing 582 tons, is the largest fusion reactor superconducting magnet ever built, with 1.3 times the volume and three times the stored energy of comparable magnets in the International Thermonuclear Experimental Reactor. Sixteen such coils will eventually form a ring generating a 6.5-tesla magnetic field at the plasma center. During heat treatment of niobium-tin superconductors, a temperature deviation of just a few degrees can cause performance to collapse, and keeping temperatures uniform across a furnace holding coils more than 10 meters in size is itself a cutting-edge engineering feat. The BEST (Burning Plasma Experimental Superconducting Tokamak) is a compact, next-generation nuclear fusion device being built in Hefei, China, aiming to demonstrate actual deuterium-tritium plasma burning and generate the world's fi...

定風波 蘇軾

  三月七日,沙湖道中遇雨。雨具先去,同行皆狼狽,餘獨不覺,已而遂晴,故作此。 莫聽穿林打葉聲,何妨吟嘯且徐行。竹杖芒鞋輕勝馬,誰怕?一蓑煙雨任平生。 料峭春風吹酒醒,微冷,山頭斜照卻相迎。回首向來蕭瑟處,歸去,也無風雨也無晴。 dugushushi 石鼓

秦趙長平之戰

  wiki kknews edbhk baidu 考古人员仅在这层就挖掘出头盖骨60多个,因天寒地冻无法再挖,专家们推测,此坑所埋赵军官兵尸体至少超过百具。此外,考古人员还运用国际最先进的射线测定法,探测到在一号坑的西侧,还有一个宽3至4米、长55米的大尸骨坑,他们将其编为二号坑。他们分析认为,此坑和附近的二号坑均为深坑,不像秦军专为掩埋战俘尸体所挖,更像是天然的深沟大壑。当年,秦军将战俘尸体抛入沟内,再填上一层薄土加以掩盖。 紙上談兵 史記 白起王翦 列傳 .…至九月,趙卒不得食四十六日,皆內陰相殺食。來攻秦壘,欲出。為四隊,四五復之,不能出。其將軍趙括出銳卒自搏戰,秦軍射殺趙括。括軍敗,卒四十萬人降武安君。武安君計曰:「前秦已拔上黨,上黨民不樂為秦而歸趙。趙卒反覆。非盡殺之,恐為亂。」乃挾詐而盡阬殺之,遺其小者二百四十人歸趙。前後斬首虜四十五萬人。趙人大震。 趙最大弱點/失敗,是在於logistics 後勤

Humanoid robot component list breakdown

  unitree G1 teardown  from baidu site jonver munro  on motortrend moomoo CNP Securities conducted a component-level teardown of Unitree G1 and found its BOM cost to be only RMB 41,600, compared to a selling price of RMB 85,000, resulting in a gross margin of up to 40.7%; the EDU version's gross margin can reach as high as 66.7%. The teardown revealed that its core hardware consists of mature components from supply chains such as Intel, DJI, and Longsys, with no significant barriers in the hardware itself. The true competitive advantage lies in proprietary motion control algorithms. However, the teardown also exposed design limitations: a single-arm load capacity of only 2kg and a battery life of 1-2 hours, making it difficult to enter industrial applications. robot hand @technialhqrobot zhihu Wechat   semianalysis nikkei
