    Don't need global shutter just use a bit more math and IMU data with frequency in excess of the frame rate. Make it work with the recording capabilities of a good modern phone and …

    There's also the potential of co-locating non-evaporative cooling with CO2-scrubbing using a strong KOH solution in the big cooling towers and regenerating the hydroxide with calci…

    It'd suffice for them to sign the transmitted information (audio and required timing metadata for the packet stream) and make you do the temporary recording on your side, transmitt…

    The tin plasma source is the one we don't know how to reproduce; in contrast we know how to do it with an electron-syncrotron (though IIRC for the energies here it is technically p…

    You could give each one a diceware-eff-wordlist-like "ID" when they input where they want to go, perhaps have a "group" and "single" button/column per destination in the menu as we…

    What battery technologies are banned??? While being good except for efficiency?

    No the beam source we know how to create; it's just that the way to do so requires a factory sized machine that better be feeding 10~30 steppers or a pair for uptime/maintenance wi…

    My fine spice recipe writing scale (20g max, 20k count) consistently over years of me having it keeps it's magnitude calibration of the 10g reference to a single digit count, i.e.,…

    The video codec does not care about VRR, it happily does it. If the receiving display can do VRR, it'll just work.

    Stop insisting on Cat.6A (and related) copper cables for speeds beyond 1000BASE-T (maybe beyond 2.5G by now), just use dumb multi mode fiber it's way easier technology-wise and if …

    A good chunk of 802 is not paywalled for individuals, notably at least 802.3 and 802.15.4, which I read good chunks of.

    The actual alternative is induction motors, which are just a bit less efficient than PMSM and otherwise basically the same. Except that the frequency fed to them isn't exactly prop…

    Yeah so the relationship between speed, power, frequency, size (both in the direction of primary flux excitation and in the direction orthogonal to both that and the movement), and…

    Actually large data centers at least if done in a vaguely alirack style architecture, can do this with a decent fraction of their nominal power for very little hardware cost, as re…

    10+ MW voltage-source converters that can't do up to around 80% of their nominal capacity as mostly-reactive apparent power with stabilizing synthetic inertia scaled as desired/spe…

    Isn't the problem with write back cache mode just due to the GPU being unable to invalidate cache lines in the CPU?

    You can also have two shunts per phase, one low side and one high side. The "hall" "shunts" are pretty good though.

    Ehhh if it's just for looking and you don't have anything lidar just go for splats they're way better behaved, mostly because they don't need to understand a concept of "surface" t…

    Dropping containers at the consumer end isn't that bad, at least when they're empty they're not that hard to move back on a truck and there are plenty of uses above scrap value for…
