  • L’espansione territoriale di Israele dall’ottobre 2023
    @anarchia
    Quali sono i confini di  Israele? Questi sono in continua evoluzione – e si respingono – dal 1949, in ogni guerra contro i suoi vicini. Troppo spesso presentate come operazioni di   “difesa”, le offensive che Tel Aviv conduce sui https://www.rivoluzioneanarchica.it/lespansione-territoriale-di-israele-dallottobre-2023/

  • Studying a Battle Born LFP Battery’s Death Under Controlled Conditions

    There has been quite a bit of news recently about the Battle Born LiFePO4 (LFP) batteries and how they are dying in droves if not outright melting their plastic enclosures. Although the subsequent autopsies show molten plastic spacers on the bus bars and discolored metal in addition to very loose wiring, it can be educational to see exactly what is happening during repeated charge-discharge cycles at a fraction of the battery’s rated current. Thus [Will Prowse] recently sacrificed another Battle Born 75 Ah LFP battery to the Engineering QA Gods.

    This time around the battery was hooked up to test equipment to fully graph out the charging and discharging voltage and current as it was put through its paces. To keep the battery as happy as possible it was charged and discharged at a mere 49A, well below its rated 100A.

    Despite this, even after a mere 14 cycles the battery’s BMS would repeatedly disconnect the battery, as recorded by the instruments. Clearly something wasn’t happy inside the battery at this point, but the decision was made to push it a little bit harder while still staying well below the rated current.

    This led to the observed failure mode where the BMS disconnects the battery so frequently that practically no current is flowing any more. Incidentally this is why you need to properly load test a battery to see whether it’s still good. In this failure mode there is still voltage on the terminals, but trying to pass any level of current leads to the rapid disconnecting by the BMS, even while as in this case the plastic spacer on the bus bar melts a little bit more.

    Despite these very rapid disconnects and observed thermal issues, the BMS never puts the battery into any kind of safe mode as other LFP batteries do, leading to the melting plastic and other issues that have now been repeatedly observed. The discoloration of the battery terminals that originally started the investigation thus appears to be a result of higher charge currents and correspondingly higher temperatures.

    Worryingly, Battle Born recently put out a statement – addressed in the video – in which they completely disavow these findings and insist that there is no issue at all with these LFP batteries. Naturally, if you still have any Battle Born LFP installed, you really want to test them properly, or ideally replace them with a less sketchy alternative until some kind of recall is issued.

    🎉 What's New in Org Social! 🎉This month the community has been buzzing about LoRa radio communications, members shared deep Emacs workflows, including GNUS for email, AUCTeX for papers, BQN/ngn/k array languages with Org Babel, pdf-tools, whisper.el voice dictation tricks, and org-alert debugging on Termux/Android. The org-publish vs Hugo debate sparked up, with one member proudly running a website built 100% with org-mode and elisp.The spirit of digital freedom ran strong: deleting big tech accounts, supporting EU tech independence, and celebrating that "in plain text, identity verification doesn't exist and never will."Also, org-social.el v2.11 was released with bug fixes found by the community itself.And yes, there were cat photos 🐱If you love Emacs and plain text freedom, join us!For more information: https://github.com/tanrax/org-social#emacs #orgmode #orgsocial

    Grandiose day! However I haven’t read the book yet thou’. I spent my evening today building a automation by forking Tinker hack Blusky integration for running playlist etc. I am halfway there but when I run tested it – the last block doesn’t seem to work so I’ve contacted them about it. I hope soon to get help. This year I did lot of techie projects for myself like vibe coding built ways for me after taking course on ai and then vibecoding snake game and all of that. Later, doing html/css course to understand the basics and loving it all and then jamming up with neocities more. This year I also got excited with Nothing community project challenge – and built a marketing plan even the date was done and all. As I got to know late – being so inspired by the brand I went ahead and did something cool too. Nothing has cool software and hardware. The UI is cool as they say it. Got back to the ropes of smartphones as I grabbed Vivo iQOO Z10X as my daily driver – as they call it! I’ve since loved watching tech videos alot. I do love tech. I am not very much diving into fitness gadgets as of yet. As that would just tumble me down of anxiety passage I find.Well, the Founder of Mastodon is giving the next baton to new guy. Felix! Also, Eugen did a wonderful job with Mastodon. I saw his interview on YouTube while dinnering my way up through the day. I also read how a 101 year old Barista has been serving since WWII – that was the good news over bsky this morning. Also one 87 year old lady did something cool – which I don’t recall. You know we don’t care much to remember good news as we keep bad news itched in our brain for like whole time and all. Bad news is impactful is it? It creates fear and then that becomes memorable all of a sudden. Ah!
