  • There are endless specific warnings about specifically opening microwaves, because this exact thinking is what has gotten hundreds to thousands of people killed over the years.
    Specifically microwaves, specifically from feeling safe because they have been sitting in a trash pile or basement for months or years.
    It happens comically often, to my knowledge it’s the most common specific cause of death in diy.


  • Sounds like you are talking about the entirety of a small circuit?
    If the circuit connects both sides of the capacitor, then it will discharge it. But that means the circuit is discharging the capacitor.

    If I am, say, putting a capacitor across neutral and live of an ac cord, then I am charging it. Then if I unplug the cord and connect the live and neutral wires, I would be discharging the capacitor.
    But … you don’t connect the wires of your plug. They are floating. If one is held at 300V from the capacitor because that was the voltage at the moment I broke the connection, then it will remain at 300V relative to the other forever.

    Floating is the default state of disconnection. If I rip the capacitor straight out of the running machine, it will be floating and will usually keep its charge for years. If your remaining circuit doesn’t contain something that can drain the capacitor, it will stay undrained.









  • If you measure response curves of individual cones and rods you won’t see any of the parameters go below the ms range, probably not even below 10ms. However the retina does receive bright short pulses as longer averaged signals. All the very high Hz vision cases see information of the same “object” spread over many cells in the retina. A trail showing up as many distinct images vs a long smear.

    If you couldn’t move your eyes the limit would be lower, but because you can’t the rendering cannot anticipate those effects and emulate them. Motion blur is what happens when you always “anticipate” the eye to remain static. If you could measure eye movement extremely well and react within well under a ms, you might be able to match motion blur to eye movement of a single person. Add a second observer and it already breaks down. Not that our sensors are anywhere remotely near making this possible.

    Edit: I suppose this would mean if you integrated a display into contact lenses and got the latency right you would max out at lower Hz.








  • This. Aegis does all of the points except offsite backups. And for good reason.
    The Aegis app has no network permissions at all, which is obviously a massive boost for security and privacy. And besides, off-device backuping is a nightmare.

    Syncing the Aegis backups made on change to some other server is better handled by a great dedicated app. Syncthing is the best such program (by far), though for the few files involved here nextcloud would work just as well.
