    Arduino Nano built in RGB LEDs won't turn off

    Also be aware modern LEDs even with uA current in them will glow. So depending on drive circuit one can have this problem. In your case you only have leakage so should be OK on this.

    tek 2712 identification of a destroyed component

    Your picture not well focused to help you determine what it is. Pre explosion. How many electrical connections to it ? Given a liquid of some sort internal to it could be a battery or a classic electrolytic .... The liquid may be caustic/acidic so cleaning the board imperative so it does not...

    "Assessed", but google "how many species are on earth" to get an idea of %age impact

    What a revelation you have posted. Of course uncertainty theory tells us an extinct species can possibly come back, the non zero probability that can happen. That was the point in mentioning mammals. Thats all occurred and its rates w/o AI. So you and I must seek the knowledge will AI...

    Excellent scientific justification. Deep insight I see. Or is that just "denial" as you put it. Earth has been evolving for millions of years, species come and gone, change inevitable. And here we are. Our species so far ~ 300,000 years. Of course we are not discussing how huge an impact, mostly...

    No question I can see AI asking itself "Who is the greatest threat to the planet in terms of my destruction, in terms of species elimination, in terms of war and death, in terms of environmental damage...., who ?" and the answer to that would be humans ! But then it would ask "If I eliminate...

    Google this "planets external to solar system with atmosphere", already findings. We have already left Earth, first baby step, eg. moon landings, several. Our robots already to extended planets Space station, astronauts already exceeding a year stay in it, 437 days to be exact. Oh for sure...

    No, actually power control would most likely be at card level, so that specific server would be idled. Of course if a volcano erupted under the center the whole center would be shutdown. There are well established "data centers", re. google search is a "data center", and multiple sites (server...

    We EE's regularly design protection circuits for excessive heat, V, current, wear.....thats old ongoing technology. They do not generate waste water, its recycled like a car engine/radiator/fan do. Problem is what is the heat sink, atmosphere, earth, radiant, conductive, where is the heat...

    The accounting is still out on AI centers. Yes water big issue, heat released, metals and chemicals needed for chip manufacture.... BUT will AI reduce errors of human designers, read wasted materials, bigger waste dumps needed to handle all the garbage ? Will AI produce better health...

    Dealing with limited GPIOs on ESP8266 vs upgrading to ESP32 for IoT security?

    I am a newbee to RTOS to handle dual cores, but the first experience, simple as it was, made a dramatic difference in code simplification. Think of all the spaghetti code we all have been writing over the years where timing task to task was crucial to get decent behavior, like display refresh...
