    I believe mailbox.org is all renewable, and I’m pretty sure it’s solar.

    But you need a massive battery bank to run stuff, batteries have a limited lifespan (especially the crap used in a UPS).

    It’s not cheap, you generally want to overbuild everything, and there are ongoing costs (hardware failures, batteries, etc).

    But it can be done. Just have to do the math for your max power draw, then how much uptime you need determines the size of your battery bank and number of panels (which is influenced by how much sun you get/how consistent it is). You need enough panels to run your system and charge batteries, given the limitations of sun availability.


  • It’s really frustrating there’s no proper backup/restore without root - that’s my primary reason for having root.

    Yea, Syncthing-Fork is still maintained, though there hasn’t been an update for a while. The company that makes Möbius Sync for iOS is a big supporter of Syncthing, hopefully they’ll help in some way. Alternatively there’s Resilio Sync, but it’s hard on phone ram - I’d have to manage it a lot more often. Though it has Selective Sync - I can browse a shared folder from my phone and tell it to sync specific files. This is great for my media server - I can grab any movie/music anytime.

    I like Syncthing-Fork better because it moves sync conditions to within each folder. So my DCIM folder syncs on any network or battery condition (so I don’t lose photos), but NeoBackup folder only syncs on wifi and while charging.

    Pretty much all folders now sync 2-way, and I export the Syncthing config on the phone whenever I change something. That export folder is also synced, so when I switch phones I just install ST, import that config, and after a couple hours the new phone has all the same stuff as the old phone. Then I launch NeoBackup and start restoring.









  • Really has virtually no battery life impact (this from 15 years of testing many phones and configurations). Perhaps 1% in 24 hours, I’d have to look at my stats.

    May have a slight privacy impact, but given the overall data collection out there, probably unmeasurable. That said, I do turn mine off a lot for the same reason, I just don’t believe it really makes a difference





  • Parallel won’t show current load of a device. Even a clamp type can be thought of as serial, it’s just picking up the EM field instead of actually carrying the current load across the device.

    Something in parallel will be powered by the same source, with it’s current load independent of the other device.

    (And yes, I had to think about it for a second, it’s not always immediately intuitive for me either.)


  • 12-18 mo?

    Can you imagine a datacenter replacing them that often?

    Don’t get me wrong, it’s very good advice to remind folks these batteries are a wear item, and to be be prepared to replace them, but if you’re having to replace them at 18 months, I’d be looking for a different, not junk, brand.

    Maybe 2 years, if I have bad power so it’s being used, a lot.

    I can only imagine batteries wearing this fast because the UPS is cheap and doesn’t have pass-through design, and instead uses the batteries constantly to provide power conditioning.
