I’m beautiful and tough like a diamond…or beef jerky in a ball gown.

  • A few years ago I decided to try the lithium-ion UPSs. I’m on my 3rd year with them, and I will never go back to lead acid. I’ve got one “classic” UPS that is still in good shape as long as you don’t try to run more than 100w from it, but when it goes, it goes.

    These use the LiFePO4 batteries, and I get close to twice the runtime as my old ones, and they don’t drop from 80% to 10% like lead acids do. The battery chemistry is also good for about 10 years of daily cycling, so assuming the electronics hold out, they seem like they’ll last.

    The only hiccup with the model I got is it doesn’t have a serial monitor connection, but you can probably fine plenty that have it.



  • You can’t uninstall Play services once it’s installed (or if you’re on a stock ROM where it’s “baked in”), but you can disable it. Apps -> Set option to “show system” -> Google Play Services -> Disable

    Will it crash as soon as I uninstall it?

    No. However, you won’t be able to use most Google apps and RCS messaging and anything that relies on Google sign in or integrated Google Maps will not work.

    You’ll also get hammered with “Google Play Services are unavailable” notifications from SO MANY APPS. Most of those, you can go into the app’s notifications and disable the alert for “Play Services Availability”. The only one I can’t disable on my phone is from Android Setup, but it only pops up once after a reboot.

    Some apps depend on it more than others. Some will just complain that Play Services aren’t available but otherwise work just the same, but others will lose some functionality depending on how they use those services. For example, my bank app still works but complains Play Services isn’t enabled.

    Most apps that depend on Play Services use it for notifications. So, with my bank app, I no longer receive transaction notifications. I can live without those, though, but some people may not be able to.

    Can I have Android but not Play Services?

    Yes. Most custom ROMs don’t include it by default or offer builds that exclude it.

    Should I use MicroG? If yes, where do I download it?

    You can only install MicroG or other Play Services features before booting into the phone for the first time (e.g. with custom ROMs), but you can’t just replace Play Services with MicroG.









  • I feel that.

    Before I downsized, I was running 3x HP DL360 G6’s with dual Xenons and 96 GB RAM each. Way overkill for my needs but I got them cheap. Unfortunately, they and my air conditioner competed to see who could use the most electricity each month. 😆

    The only thing I really lost in the scale down was the ability to spin up dev/test VMs for every little purpose. I’ve mostly just started using Docker containers for things like build environments.




  • About 220W on average with peaks around 280W. I’ve got 8 Optiplex micro PCs, 5 upcycled thin clients running smaller services, fiber ONT, another micro Optiplex as a router, a storage server, main switch, and a 5 port PoE switch for my 4 access points around the house.

    Before I downsized everything to the USFF PCs, I was running 3 old enterprise rack servers that were about 220W each.

    It’s currently running from solar from about 7am to 4pm with my small solar setup, but I’m in the process of installing a whole house PV system so hopefully will be 24/7 solar powered soon-ish.








  • Thanks, and yeah, it’s been fun putting that all together. Unfortunately I’m still learning FreeCAD so they’re not as integrated as I’d like yet, but as soon as I have time to hammer out a design, I hope to have all 3 of these and the UPS/power supply in a nice case.

    Yep, running/charging it from solar is why I ended up getting that chonky 18650-based UPS board. It’s the only one I could find that could combine 5V input and battery without dropping out (battery kicks in immediately if solar insufficient and draws the difference between input and output and charges and powers simultaneously otherwise).
