UPSes compared to guard dogs

Somebody using the handle JeffyPoooh (yes, ‘ooo’) left a comment on The Register that is an only slightly exaggerated summary of the reasons for UPSide:

You’re concerned about your family’s safety. So you get a guard dog. The dog costs a fortune. It immediately poops on the floor. Then it chews off the entire left side of your Bang and Olufson. It bites the postman’s fingers. It then sleeps through an actual burglary. And finally it eats one of your children.

This is the UPS experience: If they’re not preoccupied with smoldering their lead acid batteries, then they’re busy buzzing and arcing. Then they blow an internal fuse on the output, and your Great American Novel is suddenly lost, again, for the third time. Then there’s an actually power failure (Yay!), so they turn on their patented 387 volt offset square wave, and your PC is instantly corrupted. Meanwhile battery acid squirts out onto the ceiling, again. Then, while you’re out trying to buy a replacement PC, the UPS catches fire and burns your house down.

I’d happily pay $800 to not have one.

  1. I’m just enjoying the comments to the effect of “building a UPS is incredibly hard, and it’s just not possible for several technically-skilled people to ever build one, because!”

    Yeah, it’s a miracle that one was ever built in the first place. Probably nuclear fission involved, or maybe nerve agents.

  2. A bomb that only goes off when least expected. Sign me up.
    I expect periodic updates. Like calling the fire department when activated.

    • I’ve never had a problem with any of my UPS at home. Everything important is covered by one. One large cap in a large UPS at the HF Receiver Site at Clark went “boom” and blew panels off and made a big mess of the rest. Then one at later civilian work that had had maintenance and known issue fix deferred because the upper management thought we couldn’t afford the downtime. Until it went boom. Then two weeks later, the repaired system went boom. Then we got a brand new UPS. No booms yet.

  3. You’d spend $800 to have something *REAL* that does it’s damned job for real and does it right.

    You’ve already talked about a Maker type thing. It’s still doable. But you need to deal with Lithium Iron Phosphate type chemistry and/or ultracapacitors combined with an Arduino or something like a NanoPI Neo or Raspberry PI ZeroW type controller with an OLED/E-Paper display.

    It won’t be cheap, but that’s the point
