    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.






  • 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.

    They host software for anyone to use, and capture all the data, usage patterns, etc, for themselves, to use for their benefit, and to use against you.

    Hell, Google deleted a company’s entire dataset recently. Everything. They gave the police location data on an area and a random person, for no reason other than happening to be in the area, was arrested for murder. Nevermind that they biked through that area every day. Remember Facebook tracking pixels? Cambridge Analytica (which is currently in court)? I mean I can go on and on about how FAANG is abusive and dishonest.

    And you want to sit here and tell me they’re the answer?

    Are you just an apologist for FAANG, etc? Because you’re really sounding like one at this point.

    Who’s paying you to post this disinformation?
