Motor is a mechanical device, so I don&#39;t think any circuit simulator can simulate the mechanical behavior of a motor, with influences its electrical characteristics under load. You can simulate a motor driver circuit for sure, and you can also model the motor as a load impedance, and you can observe the output voltage waveform. But the emulator is not going to tell you whether a real motor has enough torque. If that motor costs a million dollar, you can do multi-physics circuit + mechanical FEM simulations to tell, but I don&#39;t think most engineers would simulate the whole motors to design a circuit. 2026-04-02T16:57:58Z https://yabu.me/nevent1qqs8l5jcpjt08wssfq0w0nzrpgs0mq4pac7zpv7jje58v4gaesxfzjszyryadqmg3e0yevdl5xphg8p0nfcen30c4rhaf8rmmjc2u9z6e48ex2ydj9w In reply to <a href='/nevent1qqsw2snlapskt660ltj2lu70fy2ws8qpgyzvzxn9pyr04xl2c2yp27cdcdlcm'>nevent1q…dlcm</a><br/>_________________________<br/><br/>In theory, the standard workflow is as follows:<br/><br/>1. Express the circuit schematics as a &#34;SPICE netlist&#34;, a SPICE netlist is the universal language of circuit emulator.<br/>2. Run the &#34;netlist&#34; through a SPICE-style simulator. The original SPICE was free software from Berkeley, and ngSPICE is the spiritual successor of it.<br/><br/>But in practice the problem is not that simple.<br/><br/>1. The simulator is best at simulating ideal parts, such as passive RLCs, ideal op-amps, etc. However, working with ideal parts teaches you circuit theory, but nothing about practical design with off-the-shelf parts and ICs.<br/><br/>2. Models of off-the-shelf parts and ICs exist, but often with a propertiary favor of SPICE with non-standard extentions, such as PSPICE or LTspice, so they&#39;re usually not compatible among the SPICE implementations. In particular, most models are obfuscated.<br/><br/>3. For a long time, few free software GUI existed for schematics entry. This problem is largely worked around in recent years by reusing KiCad as the front-end.<br/><br/>4. &#34;one could design and test a circuit in its entirety&#34; This is just not going to happen. Unlike IC design where there&#39;s a strong motivation for faithful simulation of all non-ideal effects, in comparison, faithful simulation is rarely attempted by most engineers for PCB-level designs. Circuit parasitics or exact internal IC behaviors are not often modeled. Simulation is used only a rough guideline.<br/><br/>5. Much background knowledge is needed to get what you want from the simulator, For example, setting up the circuit parameters of a realistic power or small-signal diode. In comparison, a breadboard allows you to just connect things randomly and see what happens. If the simulator is incorrectly configured, it can be extremely difficult to get the circuit to run at all, &#34;error: matrix is singular&#34;. Worse, you can also get non-physical results. A classic example is the startup process of a LC circuit without resistance. Without losses, initial the transient never dies, and you can two waves instead of one.<br/><br/>6. To my best knowledge, there is no ready-made mixed-domain simulations to mix passive parts, logic or microcontroller code, this is sometimes a feature for proprietary EDAs.<br/><br/>So paradoxically, I think circuit simulators are usable only after you already know some electronics. Great to try some ideas, learn circuit theory and circuit topologies. Not great to replace the oscilloscope and the breadboard. 2026-04-02T16:42:07Z https://yabu.me/nevent1qqspusq58y6d3ggnnnl0463m95g8ap6zvcnjef0j5lexngea2gl5l7qzyryadqmg3e0yevdl5xphg8p0nfcen30c4rhaf8rmmjc2u9z6e48ex5p6893 Saw a #Linotype today after walking into a museum on the side of the road while returning home.<br/> <img src="https://misskey-taube.s3.eu-central-1.wasabisys.com/files/webpublic-2071f658-b692-4a25-9603-f881957dabcf.webp"> <br/> <img src="https://misskey-taube.s3.eu-central-1.wasabisys.com/files/webpublic-8f1b6556-2600-4a09-8680-b07baeb04a7e.webp"> <br/> 2026-03-31T07:06:40Z https://yabu.me/nevent1qqszuv9sp70akncm2h40y5f2wwpqe6zgvrure0g0jq8n7nfzznv2pfczyryadqmg3e0yevdl5xphg8p0nfcen30c4rhaf8rmmjc2u9z6e48exj7e5cf The US heat pump trend sounds pretty funny, since in some parts of the world, running in reverse for heating is a default feature of all air conditioners for decades, it&#39;s like saying you&#39;re buying &#34;the Chromascreen receiver&#34; instead of &#34;a TV set&#34; because it has colors. 2026-03-23T16:15:03Z https://yabu.me/nevent1qqs9z62ntjqp23pg56g03m5fm8eqefvvslzv22extz572evrdt0pehqzyryadqmg3e0yevdl5xphg8p0nfcen30c4rhaf8rmmjc2u9z6e48extkz78s In reply to <a href='/nevent1qqsg4errsshrn607pltsxqnzueqkcgcu7ku5fedck6cglt6kv0hdhagv3zt75'>nevent1q…zt75</a><br/>_________________________<br/><br/>Didn&#39;t the 2017 sequential resilver patchset already significantly improve the disastrous performance? <a href="https://github.com/openzfs/zfs/pull/6256">https://github.com/openzfs/zfs/pull/6256</a> Or is that still too slow for many poeple? 2026-03-11T09:02:13Z https://yabu.me/nevent1qqsqlcspg0t7v8qrrj2clhy9yc3u36sw63n2uw8yh9lwhykw8xj7njszyryadqmg3e0yevdl5xphg8p0nfcen30c4rhaf8rmmjc2u9z6e48exjz5c4e In reply to <a href='/nevent1qqs0elg2d8zn4gattmfdp67cw8d7eywycsc03rg4aqulvnv0l7nelaqu0j3sr'>nevent1q…j3sr</a><br/>_________________________<br/><br/>Fun fact: many famous shooting games existed on Japanese feature phones as i-mode apps, running on the DoJa runtime, NTT DoCoMo&#39;s variant of J2ME.

There are only guesses: buggy controller logic behaves unpredictably with non-FAT32, journaling increases unclean-unplug FTL corruption risks of already-buggy logic, etc. I wonder if anyone ever seriously engineered or reverse-engineered one of those to see what exactly went wrong in the firmware? 2026-01-31T19:41:00Z https://yabu.me/nevent1qqsqjzmtgx2s5kgtpcfty9ax43z2alvddy6qt3jtw9wun22h5xjk95qzyryadqmg3e0yevdl5xphg8p0nfcen30c4rhaf8rmmjc2u9z6e48ex2g4qlr &gt; &#34;Strangely the only people who’ve developed software to reset flash controllers are the Russians, maybe they’re used to this.

The consequence of this system is that most software projects are not a product, there&#39;s no such a thing called &#34;the software&#34;, but a human process: reporting issues, creating breakages, writing patches, doing CI/CD, packaging for distro, that are in constant motion. If the motion stops, the software will stop working very soon.<br/><br/>If you look at a Win32 app, it&#39;s exactly the opposite - it&#39;s a product, not a process, once it&#39;s completed it&#39;s &#34;set in stone&#34;, and some people will still use the same binary 20 years later, sometimes they spend great effort to keep the mysterious binary running, even when very little is known about it. The later &#34;minimum maintenance&#34; approach is historically rarely used by the free software community. Perhaps some projects should try it seriously. 2024-10-26T12:54:34Z https://yabu.me/nevent1qqspwl5xzvd3760guv2870dy8x9qfdyhk7asact6q4lkgwwal9ngxlszyryadqmg3e0yevdl5xphg8p0nfcen30c4rhaf8rmmjc2u9z6e48exgpz6u4 Congratulations, the screenshot showed that you&#39;ve just passed the Internet Operator Competency Assessment Test of China, Level 1 (Learner, China in 2005). To obtain higher levels of certification, study the following subjects:<br/><br/>Level 2 (Beginner, China in 2007): Upgrading all deployed network protocols to encrypted versions, not only TCP but DNS and TLS SNI. If no encrypted version is available, use heuristic filters to ignore spoofed results.<br/>Level 3 (Technician, China in 2010): Implement an original tunneling protocol resistant to keyword Sniffing, TCP reset attacks, and active probing.<br/>Level 4 (Professional, China in 2013): Design an anti-traffic policer to maintain high throughput under intentional QoS and packet loss. Assess its effectiveness for China Telecom, China Unicom to Hong Kong, Korea, Japan, Singapore, USA, and Russia.<br/>Level 5 (Engineer, China in 2015): Run multi-city network congestion monitoring servers via ping and traceroute. Learn the topology of domestic and international network backbone using self-study materials of mixed quality, identify key ISPs with good peering and transit relationships using BGP Looking Glass. <br/>Level 6 (Expert, 2000-2024, always ongoing): Develop an original exploit to disrupt or de-synchronize stateful firewalls, such as manipulating packet fragmentation bit, spoofing SYN, ACK, FIN, allowing the Great Firewall of China to ignore your traffic completely.<br/><br/>By completing these certifications, you would be able to surf the Internet and looking at GitHub source code and American cat pictures with confidence.<br/> <img src="https://misskey-taube.s3.eu-central-1.wasabisys.com/files/c08f7a27-97c4-4236-9afe-d9f704a00dee.webp"> <br/> 2024-10-25T17:18:47Z https://yabu.me/nevent1qqsffvse4wdpp9l9x9w86cmrrctp0jlyra5mwme40m8jh6t0pxsgu2qzyryadqmg3e0yevdl5xphg8p0nfcen30c4rhaf8rmmjc2u9z6e48exl93g4q The Unix permission mapping features (cifsacl, idsfromsid, modefromsid) provided by Linux&#39;s CIFS driver for SMB v2+ are completely undocumented!
