  • I’ve been pleased with it. Family is very relaxed about projects like this, but yeah it’s low power draw. I don’t think I have anything special set up but the right thing to do for power would be to spin down drive when not in use, as power is dominated by the spinning rust.

    Uptime is great. Only hiccups are that it can choke when compiling the ZFS kernel modules, triggered on kernel updates. It’s an rpi 3/1GB RAM (I keep failing at forcing dkms to use only 1 thread, which would probably fix these hiccups 🤷).

    That said, it is managed by me, so sometimes errors go unnoticed. I had recent issues where I missed a week of rsync because I switched from pihole to technitium on my home server and forgot to point the remote rpi there. This would all have been fixed with proper cron email setup…I’m clearly not a professional :)

    High frequency is generally bad for transmission line losses, so getting power from A to B is better at lower frequency — DC is a great option here.

    If we switched to DC, many things would still flicker though as they would presumably use switching power supplies, but those could be relatively high frequency like you said.

    Interestingly, airplanes use 400Hz, as transmission over distance doesn’t matter, and transformers can be made much smaller/lighter.
