  • When I need to run something that I can’t or won’t run at home, I usually spin up a machine at Hetzner. Cheap, reliable, and setup is fast. The server auction can give you a pretty nice hardware stack at a low cost, and you can cancel at any time.

    However, the cases were I use hosting providers are becoming fewer and fewer, as I’m in the final stages of rebuilding my “homelab” the way I want it. If only those UPS batteries could arrive soon…


  • Anything made to be run from battery can work fine without one. Worst case scenario requires you to spoof some I²C communication to properly emulate a battery, but most devices and batteries are far dumber than that. DC is DC, and sometimes you just need to graft something on top for the other pins.

    Source: My old laptops charging circuit failed, so I soldered the charger onto the battery pins instead. Then I replaced the actual battery with an Adafruit Itsybitsy 32u4 (because that what I happened to have available) that emulated the battery status of “Charging, nothing to see here, move along” and sent it via I²C
