  • It will not affect system stability, but… Surge protectors do not work at all without a ground wire to drop excess voltage to. Any kind of line voltage disturbance could kill every device.

    Additionally, without any ground wire to pull the housings of devices to ground, the potential for a short to energize the case and then electrocute you is also high.

    additionally additionally, if you have grounded outlets that don’t actually have a ground connection running to them, that means either the wiring system is broken or it was “updated” by an unlicensed hack job who has undoubtedly made numerous more dangerous decisions elsewhere in the circuit.

    If your house is entirely ungrounded you really should have an electrician come update it ASAP. Outlet grounds have been mandatory since 1971. The chances are high that wiring predating that code is still using old cloth-wrapped wire insulation or even knob&tube, both of which are huge fire risks as the insulation is decayed badly by now. It’s expensive to have all new wire pulled but it is necessary.










  • it’s because implementing an existing touch screen module and then telling a bunch of code monkeys in a 3rd world country to write a barely functional UI for it is actively cheaper than engineering, sourcing, assembling and testing keypads with physical buttons or even a membrane keyboard these days

    using a touch screen also means they can put the same mass produced PCB into 40 different products instead of needing a custom button pattern for each. just tell the code monkeys to update the UI. there’s a lot of economic arguments for the use of touch screens, but it sure doesn’t make the field worker’s lives any easier.





  • This is true. If you left it in the same environment it would eventually return to equilibrium and the net result would be the same. the key is that the plastic has a limited take up rate of atmospheric moisture. so if you dry it for a few hours, the water migrates out slowly, but then takes quite some time to migrate back in.

    generally people either print from a dryer box or dry filaments immediately before printing.
