An optocoupler is an electronic device that sends a signal using light while keeping two circuits electrically separate. It is used to protect sensitive parts of a circuit from high voltage, reduce noise & safely connect control circuits to power circuits. It's used in power supply regulation, microcontroller protection, motor control & switching high-voltage loads.

@OT_1269 @QuantaMagazine 🤣 damn son it’s like the new Milwaukee drills

Biologists have been unpacking the mystery of the flagellar motor for decades. It wasn’t until this year that the final pieces of its dynamic puzzle finally fell into place. “My lifelong quest is now fulfilled,” said Mike Manson, a professor emeritus of biophysics at Texas A&M University who started studying the flagellar motor in the 1970s. “I finally understand how this thing I’ve been studying for 50 years actually works. That’s about as satisfying as can be.” quantamagazine.org/what-physical-…

Want to learn how to analyze an RF device block by block, without any docs? Here's a thread I've written on exactly that, with a real product as the example. Some sort of high-level reverse engineering for beginners.

What you really need to know about variable resistors or potentiometers, pots. Whether you call them variable resistors, potentiometers, or simply "pots," these components are essential electronic components of the electronics world. From the volume knob on a vintage radio to the precision adjustment in a high-end medical device, variable resistors allow us to bridge the gap between fixed circuit design and real-world adjustability. Drawing on insights from my Electronics Notes website, here is a breakdown of why these components are essential and how to choose the right one for your project: 1. Potentiometer vs. Preset: Know the Difference • Adjustable (Potentiometers): These feature a spindle and knob, designed for frequent user interaction (think volume or tone controls). • Presets (Trimmers): These are small, internal components adjusted during manufacture or maintenance. They are meant to be "set and forget." 2. Material Matters The "track" material changes everything from power handling to noise levels: • Carbon Composition: The most common and cost-effective. • Cermet: A ceramic-metal composite ideal for high temperatures and offering much lower noise than carbon. • Wirewound: Often used for high-power applications where precision and durability are paramount. 3. Linear vs. Logarithmic Taper This is where many designers get tripped up! • Linear (LIN): Resistance changes at a constant rate. Best for most measurement and calibration tasks. • Logarithmic (LOG): Resistance changes slowly at first and then rapidly. Why? Because human hearing is logarithmic! We need a "Log" pot for audio volume so the increase sounds smooth to our ears. 4. Rotary vs. Slider • Rotary: Space-efficient and the standard for most "knob" interfaces. • Sliders: Common in audio mixers and lighting desks. They provide a clear visual representation of settings across multiple channels. In a world moving toward digital-everything, the tactile, reliable nature of the variable resistor remains a cornerstone of electronic design. Are you working on a project that requires precise calibration? Or perhaps designing a user interface that needs that perfect "analogue feel"?

Before we can use a FPGA, we need to design it correctly on to its board. Tomas Chester is one of the best there is at this, his latest Horizon article looking at Sparse vs Dense breakout is one you should definitely read. Either as electronic engineer or FPGA designer. issuu.com/fpga-horizons/…

Tuve que trabajar este fin de semana y no pude grabar. Pero ya está el material de inicio para el curso que lanzaré en el canal que iniciaré. Esten atentos!!

@IntensoPolitica @MNI_CDMX Eres un puto comunista, ya es redundante que debas defenderlo, pedazo de mierda. Tienes el cerebro conectado al culo.

@OT_1269 @MNI_CDMX Me sorprende el nivel de estupidez que puede manejar la masa y después no asumir su responsabilidad.

Esto es lo que tiene que pasar cada que un imbécil sale a querer defender la izquierda, el marxismo o cualquiera de esas ideologías que han resultado en colapsos irrecuperables. No son ideólogos solo son parásitos levantando la bandera de la justicia social y esperando su turno para robar.

これ利用して電気回路で機械振動を模擬できます！制御工学とかにもつながるのでおすすめです！！

@IntensoPolitica @MNI_CDMX ¿Quién dijo que los estabas defendiendo?, ni leer sabes hijo de la puta y desenfrenada verga JAJAJAJAJAJAJAJAJAJAJAJAJAJAJA

@OT_1269 @MNI_CDMX ¿Quién está defendiendo el comunismo? ¿Defender la libertad de expresión es defender el comunismo, imbécil?

对半导体芯片处理器感兴趣的朋友 可围绕 Open Source EDA 展开学习、实验、仿真 虽然开源 EDA 和 EDA 三巨头的商业产品还存在较大差距 但开源 EDA 给了我们一个学习和实验的绝佳途径与平台 这些开源EDA解决方案配合模拟仿真软件和形式化验证，形成统一开源方案，正在把不同的工具结合一个集成化设计环境（IDE） 背景知识： 原子物理学、半导体物理学、RISC-V、量子力学、量子计算 量子理论应用：量子化学、量子光学、量子计算、超导磁体 发光二极管、激光器、晶体管和半导体如微处理器等 需多关注 HDL,RTL（寄存器传输级） C++/SystemC,VHDL,GHDL,Verilog,SystemVerilog,Clash,Chisel/FIRRTL IEEE 1076 VHDL IEEE 1666 SystemC IEEE 1800 SystemVerilog IEEE 1850 Property Specification Language (PSL) KiCad 就是这样的开源 EDA IDE 附图是我在 Mini M4 上运行 KiCad 10.0.1 的效果 这是 Antmicro Jetson AGX Thor 底板 为 [NVIDIA Jetson AGX Thor (T5000)] 系统模块设计的底板的开源硬件设计文件，包括的开源组件也发布至 GitHub github.com/antmicro 类似这样结合开源软硬件设计、实验、仿真的学习实践思路大家可参考

@ChefBoiRDoge @QuantaMagazine Is brushless, my todo pendejo 😂

@QuantaMagazine Why’s it got a stator but no rotor haha does it got field windings too and slip rings 😂

量子力学是晶体管半导体发展的基础 半导体物理学的研发严重依赖于量子力学 晶体管半导体是集成芯片里的基本单元 量子力学在电子器件中有着广泛应用 现代计算机的基础，微处理器，由上亿个半导体晶体管集成 且随着晶体管数量的增加，晶体管中的量子效应越来越明显 量子力学对于解释和模拟半导体器件中的电学、光学、热学性质等尤其重要 还有量子计算，量子计算机就使用量子位作为基本单位 量子位由不同的电子态叠加形成 《半导体物理学》+ 量子理论（量子力学） 可以作为研究和学习方向，半导体芯片产业的巨大市场 买了本《半导体物理学 (第七版)》（二手书） 附件是教学 PPT 幻灯片，大家可直接下载参考学习 docs.huihoo.com/physics/the-ph… 个人兴趣学习方向也从开源软件转向软硬件结合： 机器人、电子器械、芯片、半导体等 希望在未来生活压力没那么大时 能更多投入到数学和物理的学习中

@nohayred ¿Y que hace el cabrón todo el día en la casa?, tan fácil que es divorciarse para que se ponga a trabajar y todavía llegué de sirvienta para sí misma, pero no, a la puta le gusta parasitar y que le dé verga otro que no sea el marido 😂

Asi es la vida de toda mujer después del matrimonio 😭

エンジニアの皆さん。 ラズパイで最初に書いたPythonの1行、 覚えていますか？ 私は GPIO.output(17, True) でした🐍 ブレッドボードに挿したLEDが ピッと光った瞬間、 画面の中だけだったコードが 現実の世界に染み出してきた感覚で、 今でもはっきり覚えています。 print("Hello") の感動とはまた別軸で、 「コードで物理が動く」体験は ラズパイにハマる決定打でした。 皆さんの「最初の1行」、何でしたか？ ライブラリ名でも import 文でも、 覚えている方はぜひ教えてください👇 #RaspberryPi #Python
