    Most autos have an override to shift manually and engine brake more, hardly ever see people use them except if they tow frequently though. A lot of CVTs have virtual gears for that…

    There’s a few luxury cars that use the same or larger engines for the hybrid. Lexus did it with the LS, hybrid 600h had a larger engine (5L) than the gas 460 (4.6L). Those are supe…

    Yeah and it prevents issues if the subject line changes in an unexpected way that confuses the email client, or issues where an email chain goes on for a long period of time but re…

    The PCB is easy to screw up, so are the cables. And scopes that go that high are expensive but customers expect USB3 even on low volume low cost products so there’s definitely adva…

    Yeah, this is a well known technique for boosting resolution. For example: You add a dithering signal which can be processed out. If the signal has the right properties (for exampl…

    Did some similar testing with an on-off rocker switch for a project last year. Traces were highly predictable if you pressed it just gently past the detent. But if you did it too s…

    I don’t see a world where this is possibly cheaper than just putting a AC-DC supply at the point of load. Looks like a big safety hazard too. IDK, but I wouldn’t even want to debug…

    This is true for basically any AD windows login. If you log in with an account on a machine on your domain, then take that machine offline and change the password elsewhere- you ca…

    No, unplugging works because cables are antennas. Power cables being disconnected dramatically reduces the ability for the lightning to couple into the device The device itself usu…

    You could have some moving element with limit switches and an encoder, that’s pretty common. There’s probably others… Normally the limit switch would be reliable but it will degrad…

    Interest, military, and social security are the only things big enough to cut to fix the deficit much less pay down the debt. The entire rest of the government could be free and we…

    I mean commodity hardware usually did ok in games consoles prior to then too. NES was a modified commodity chip

    What’s the average IPC of these chips for a reasonable workload? Early processors were typically 1 or lower. Modern stuff is all superscalar piplined and out of order and can do wa…

    Logitech makes them. Ergo k680 is sitting on my desk right now and has both cmd and option in the correct spots. Wireless tho so you’ll have to get over that one. Not a lot of opti…

    Yes that sort of stuff happens all the time in the business side of things. There’s a reason it’s a trope. Not to every company per se but it’s been commonplace well probably for a…

    Over 100nF of unbalanced Y-caps is needed at 60Hz/120V to see 5mA gnd current. That would be a big Y capacitor (2.2n or lower is common) and they’re usually used in a balanced conf…

    That exit strategy sounds suspiciously similar to a technique I’ve heard for lucid dreaming. Wonder if they’re related?

    Your estimate is late by almost 20 years - the first of that generation graduated high school ten years ago. But the problem is that over those ten years google docs mostly feels l…

    There’s oscillators out there that slowdown as they brownout. That would cause those symptoms. A lot of logic families have slower edges and longer delays too, not that there would…

    Chipquik works fine. There’s probably better stuff but it is consistently good and doesn’t seem to go bad (i can’t tell much performance stuff between a roll that’s old enough to h…

    1) board preheat. In a pinch, heat gun or old hairdryer. But ideally get a cheap ceramic one off amazon or something. Typically set it to 75C for delicate components. For sturdy bo…

    They probably just provide extra power over the port. It costs extra to design an extra supply for a specific port so it’s probably shared, and likewise also costs extra to current…

    Seconded. There’s almost certainly NXP IP used in nearly all NFC implementations which makes them subject to their terms. Those terms are in turn set by the partners that asked for…
